A strong upper level trough moved out of the southern Great Basin and into the Lower Mississippi Valley pulling Artic Air southward to the Gulf Coast. Moisture laden air from the Gulf of Mexico moved northward and overran freezing surface temperatures producing an ice storm across the region. Ice accumulations of one to four inches left upwards of 30,000 homes without power due to ice covered tree limbs which snapped and dropped powerlines. Bienville, Clariborne, Lincoln, Ouachita, Union and Webster parishes were declared disaster areas and became eligable for federal aid. Total area damage in these zones ran nearly 7 million dollars. Damage breakdown by individual Parish are not available through this source. Hundreds of chicken houses and carports collapsed from the weight of the ice and snow.

Very hot and moist low-level southerly winds became enhanced along and ahead of a stalled frontal boundary draped near to just north of the Interstate 20 corridor of East Texas and North Louisiana. An upper level ridge of high pressure also expanded northeast from Mexico across much of Texas. As a result, afternoon temperatures climbed into the mid to upper 90s over these areas. When combined with the high humidity, heat indices ranged from 110-119 degrees from the June 17th through the 20th. Although slightly cooler and less humid conditions moved into North Louisiana on June 21st, a 62 year old female was found dead in her home in Keithville (Southern Caddo Parish) following several days of no electricity after severe thunderstorms resulted in widespread power outages on June 16th. The Caddo Coroner's Office stated that the victim had suffered from previous health issues, and that the intense heat and humidity led to hyperthermia, and ultimately, her death.

A large and amplifying upper trough dug south through the eastern two-thirds of the United States along and east of the Rockies on December 22nd, which ushered in the coldest temperatures for December in decades to much of the country leading up to the Christmas Day holiday weekend. This very cold arctic air mass moved into extreme Southeast Oklahoma, Southwest Arkansas, and Northeast Texas during the morning hours of the 22nd, with temperatures falling sharply some 20-30+ degrees with the attendant cold frontal passage into the single digits and lower teens by the morning hours of the 23rd. Very strong and gusty northwest winds of 35-45 mph were observed behind the front even through the morning of the 24th, producing a long duration of wind chill values ranging from 0 to as low as -10 degrees across North Louisiana from the evening of the 22nd to the morning of the 24th. While the temperatures associated with this arctic air mass were not quite record-breaking for this time of year, the long duration of subfreezing temperatures, which persisted nearly 2 days, resulted in multiple reports of freezing and bursting of water pipes, as well as sporadic power outages across these areas.||Here are the lowest wind chill values recorded across North Louisiana from December 22nd through the morning of the 24th:||Caddo Parish: 9 S Barksdale Air Force Base, -10 degrees; Shreveport Regional Airport, -8 degrees.|Bossier Parish: Red River Research Station, -10 degrees; Shreveport Downtown Airport, -8 degrees; Bossier City, -8 degrees, Barksdale Air Force Base, -8 degrees.|De Soto Parish: Mansfield, -4 degrees.|Webster Parish: Minden Airport, -7 degrees; Minden, -3 degrees.|Bienville Parish: Bienville, -1 degrees. |Claiborne Parish: Caney RAWS, 3 degrees.|Lincoln Parish: Ruston Regional Airport, -5 degrees. |Union Parish: MS-Msr Port No. 3, 3 degrees.|Ouachita Parish: Monroe Regional Airport, -4 degrees; 6 N Monroe, -2 degrees; Monroe, -1 degrees. |La Salle Parish: Jena, 8 degrees.|Grant Parish: Dry Prong, 6 degrees; Catahoula RAWS, 6 degrees. |Winn Parish: Gum Springs RAWS, 0 degrees; Georgetown, 1 degrees. |Natchitoches Parish: Natchitoches Airport, -5 degrees; 2 N Natchez, 0 degrees; |Sabine Parish: Peason Ridge, 1 degrees; 3 NNE Hornbeck, 8 degrees.

A surface low was centered over the southern Texas Panhandle with a stationary front extending through southern Oklahoma into southern Arkansas eastward into northern Mississippi. A dry line extended southward from the surface low through west Texas into the Big Bend Country along with a cold front draped southwest from the surface low into southeast New Mexico. Aloft, an upper-level low was initially centered just east of the Rockies in eastern Colorado before tracking into eastern Kansas and eventually into the Ozarks on the morning of May 6th. Meanwhile, the surface low shifted along the Red River Valley with the cold front trailing along the I-35 corridor, shifting farther east into the Ark-La-Tex region on the afternoon and evening of May 5th. As a result, an ongoing complex of showers and thunderstorms over Oklahoma strengthened as they moved into a more unstable environment during the afternoon ahead of the cold front and upper low, becoming strong to severe across portions of Southwest Arkansas, East Texas, and Northwest Louisiana. These storms downed trees and power lines across portions of Northwest Louisiana before weakening by late afternoon, away from the stronger forcing along the cold front and closer to the upper low.

A large upper trough dug through the Southern Plains during the afternoon and overnight hours on April 12th-13th, allowing the dry line to mix east into Central Texas. Large scale forcing increased along the dry line across Central Texas during the late afternoon through the evening, as these storms tapped moderate instability and increasing wind shear ahead of this system. In fact, isolated showers and a few thunderstorms developed during the mid and late afternoon across portions of Northeast Louisiana, with one storm spawning a brief tornado over Northeast Ouachita Parish near the Swartz community. These storms over Central Texas eventually developed in a quasi-linear convection system (QLCS), as they became severe and accelerated east across much of East Texas and North Louisiana during the evening through the early morning hours of the 12th-13th. Instances of damaging winds were reported from these storms, downing numerous trees and power lines, and even spawning isolated tornadoes as well. While these storms exited the region prior to daybreak on the 13th, additional showers and thunderstorms developed along the associated cold front across East Texas during the mid and late morning of the 13th, before spreading into North Louisiana during the peak heating of the afternoon. Thus, adequate instability developed such that some of these storms again became severe, producing instances of damaging winds over portions of North Louisiana and an isolated tornado over Eastern Winn/Western Caldwell Parishes. These storms finally exited North Louisiana during the late afternoon hours of the 13th.

A longwave trough dug into the Southern Plains from the Central and Southern Rockies during the evening through the early morning hours of November 10th-11th, which reinforced a cold front southeast into these areas. A strong low level jet ahead of the front and attendant trough allowed for moisture to deepen across much of Texas and Oklahoma, with increased large scale forcing contributing to the development of numerous showers and thunderstorms over these areas during the evening of the 10th, which organized into a squall line as it pushed east of the I-35 corridor into the Four State Region. These storms weakened as they entered the area, but re-intensified over portions of extreme Eastern Texas and Northwest Louisiana during the early morning hours of the 11th, producing several reports of wind damage which downed trees and power lines. This squall line also produced two brief tornadoes over Southern Harrison County Texas and another two brief tornadoes over Northwest Louisiana, before weakening as they moved east into North-Central Louisiana.

A complex of showers and thunderstorms developed during the early morning hours of June 7th across Northwest Texas, and shifted east-southeast across North Texas throughout the morning, ahead of a shortwave trough that ejected east beneath an upper low pressure system that had begun to lift north across Southeast Oklahoma and Western Arkansas. The air mass ahead of this complex of storms across the Ark-La-Tex warmed considerably throughout the day, resulting in moderately unstable conditions within a marginally sheared environment. Thus, the storms intensified as they entered East Texas and remained severe and they progressed east across Southern Arkansas and North Louisiana. Trees and power lines were downed throughout the path of these storms across North Louisiana, before they exited the region during the late afternoon.

An upper low dove southeast across the Central Plains during the early morning hours of May 28th, with the associated upper trough axis quickly shifting southeast into the Southern Plains, along an attendant cold front. A southerly low level jet quickly spread low level moisture north ahead of the front, while also enhancing convergence along the front to allow for a complex of showers and thunderstorms to develop over portions of Oklahoma and North Texas. These storms produced a strong cold pool resulting in very strong to occasionally severe winds across East Texas, which downed sporadic trees before re-intensifying as they entered Northwest Louisiana during the pre-dawn hours. As a result, additional trees and power lines were downed, with an isolated tornado also touching down in Minden (Webster Parish).

On the heels of the first winter storm and historically cold temperatures observed earlier in the week across all of the Southern Plains and much of the Lower Mississippi Valley, a second significant winter storm developed across much of these areas from February 16th-18th, with areas of snow, sleet, and freezing rain (some heavy) falling across all of North Louisiana. Strong forcing and moisture associated with the next upper level trough to move atop the extensive arctic air mass in place resulted in widespread snow and sleet totals of one to three inches, with isolated higher amounts in excess of five inches over areas bordering the Arkansas state line. Strong overrunning of warmer air atop the shallow freezing air mass in place resulted in areas of freezing rain developing over the southern and eastern sections of North-central Louisiana, with ice accumulations of a tenth to a half inch observed.||The following are snow and sleet totals that were recorded at various locations across North Louisiana from this second winter storm:||Caddo Parish: Shreveport Regional Airport: 2.5 inches, Shreveport Southern Hills: 2.3 inches, 13 NNW Shreveport: 1.5 inches, Keithville: 1.1 inches. ||Bossier Parish: 4 W Plain Dealing: 5.3 inches, Red River Research Station (South Bossier City): 4.1 inches, 5 NW Bossier City: 3.0 inches, Benton: 2.5 inches, 4 S Bossier City: 1.0 inches.||Desoto Parish: Stonewall 5 NE: 1.5 inches, Mansfield: 1.0 inches.||Webster Parish: Sarepta: 4.0 inches, Minden: 2.0 inches.||Claiborne Parish: 1 N Homer: 3.5 inches. ||Lincoln Parish: Choudrant: 1.5 inches. ||Ouachita Parish: 2 SSW Swartz: 1.2 inches, Monroe Regional Airport: 1.2 inches. ||Jackson Parish: Jonesboro: 0.1 inches. ||Sabine Parish: Converse: 0.1 inches. |||The following are ice accumulations from freezing rain that that were recorded at various locations in North-central Louisiana from this second winter storm:||Caddo Parish: 3 SW Shreveport: 0.13 inches. ||Desoto Parish: Stonewall: 0.10 inches. ||Red River Parish: Coushatta: 0.25 inches. ||Bienville Parish: Arcadia: 0.15 inches. ||Claiborne Parish: 1 NNW Lisbon: 0.10 inches. ||Lincoln Parish: Choudrant: 0.10 inches. ||Ouachita Parish: West Monroe: 0.50 inches, 1 NNE Monroe: 0.30 inches, 2 NW Monroe: 0.15 inches. ||Caldwell Parish: Columbia: 0.25 inches. ||Jackson Parish: Jonesboro: 0.20 inches. ||Winn Parish: Winnfield: 0.25 inches. ||La Salle Parish: Jena: 0.25 inches. ||Grant Parish: Dry Prong: 0.20 inches. ||Natchitoches Parish: Natchitoches: 0.25 inches. ||Sabine Parish: Many: 0.10 inches, 1 W Zwolle: 0.10 inches. ||When combined with the previous winter storm on the 14th-15th, widespread snow and sleet totals of two to five inches were observed across much of North Louisiana, with isolated higher totals of six to ten inches along the northern tier parishes bordering Southern Arkansas. In addition, widespread ice accumulations of a tenth to near a half inch of ice accumulated on trees and power lines with the second winter storm across the southern and eastern sections of North-central Louisiana. These totals crippled the region, making driving nearly impossible, with rolling blackouts further aggravated by the additional power outages the snow and ice were responsible for. In all, over 100,000 customers lost power from this second winter storm across Northern and Central Louisiana. ||The weight of the snow and ice from these two back to back winter storms also resulted in numerous metal carport canopies collapsing across North Louisiana, with many homes and cars damaged. A portion of the roof at the Hirsch Coliseum at the Louisiana Fairgrounds in Shreveport also collapsed under the weight of the ice and snow as it began to melt on February 22nd, as it slid down the slanted metal structure onto the flat-roofed additions to the building. Extensive damage was done to the food preparation area, the hockey team's weight room, the team's laundry facility, and a woman's lavatory. In addition, a fence on the west side of the building was damaged, as was a local car dealer's display vehicle in front of the Hirsch.

Cold, Canadian air spilled south into the Southern Plains and Lower Mississippi Valley during January 9th and 10th, ahead of strong high pressure over the Central Plains. Meanwhile, an upper trough traversed the Southern Rockies on the 9th and amplified upon entering the Southern Plains during the early morning hours of the 10th, producing a large swath of heavy snow across much of Western and Central Texas, which eventually moved into East Texas and North Louisiana during the afternoon and evening hours. Snowfall amounts ranged from two to near five inches across much of North Louisiana. These accumulations resulted in treacherous travel conditions across these areas, with the weight of the heavy wet snow contributing to a total of 56,128 customers without power across the AEP SWEPCO service area across East Texas and North Louisiana. An additional 4,300 Cleco customers were also without power across North and Central Louisiana following this winter storm. ||Here are the snowfall totals measured from various locations across North Louisiana: ||Caddo Parish: 1 N Mooringsport: 4.0 inches, Shreveport Regional Airport: 3.2 inches, Shreveport Town South Estates: 2.7 inches, 12 NNW Shreveport: 2.5 inches, Keithville: 2.5 inches, NWS Shreveport: 2.4 inches, Blanchard: 2.0 inches, 5 SSW Belcher: 2.0 inches, Shreveport Southern Hills: 2.0 inches, Shreveport Spring Lake: 1.5 inches. ||Bossier Parish: Red Chute: 3.5 inches, Haughton: 3.0 inches, 4 S Bossier City: 3.0 inches, 5 NE Benton: 2.8 inches, Bossier City: 2.8 inches, 5 N Bossier City: 2.8 inches, Red River Research Station: 2.8 inches, 6.7 NNW Bossier City: 2.0 inches, Taylortown: 2.0 inches, 4 W Plain Dealing: 1.2 inches. ||Desoto Parish: Pelican: 5.8 inches, Keatchie: 5.5 inches, Grand Cane: 5.0 inches, Logansport: 4.0 inches, 1 NE South Mansfield: 4.0 inches, Stonewall: 3.0 inches, Mansfield: 3.0 inches, Stanley: 3.0 inches.||Red River Parish: Coushatta: 5.5 inches, 4 SSE Hanna: 4.5 inches, Hall Summit: 2.9 inches. ||Bienville Parish: Sailes: 4.0 inches, Saline: 4.0 inches, 5 WNW Gibsland: 2.8 inches, Arcadia: 2.0 inches.||Webster Parish: Minden: 3.0 inches, 2.2 NE Minden: 2.1 inches. ||Claiborne Parish: 1 N Homer: 4.0 inches, 3 ESE Homer: 2.0 inches. ||Lincoln Parish: 5.3 ENE Ruston: 3.5 inches, Ruston: 3.3 inches, Dubach: 3.0 inches, Simmsboro: 3.0 inches, Choudrant: 3.0 inches.||Union Parish: Spearsville: 4.1 inches, Farmerville: 4.0 inches, Downsville: 3.5 inches, Rocky Branch: 3.2 inches. ||Ouachita Parish: East Monroe: 4.0 inches, West Monroe: 3.2 inches, 4.3 SSE Calhoun: 3.0 inches, 2 NW Monroe: 2.3 inches. ||Jackson Parish: Jonesboro: 5.0 inches, Eros: 4.8 inches, Hodge: 4.0 inches. ||Winn Parish: 1 NNE Winnfield: 2.0 inches. ||Caldwell Parish: Columbia 4.1 NNW: 4.5 inches, Columbia Lock and Dam: 4.5 inches, Columbia: 3.0 inches.||La Salle Parish: Urania: 3.0 inches, Jena: 2.3 inches. ||Grant Parish: Colfax: 2.6 inches, Verda: 2.6 inches, Dry Prong: 2.5 inches, Hargis: 2.3 inches. ||Natchitoches Parish: 2 SSE Provencal: 6.0 inches, Marthaville: 5.3 inches, Goldonna 4.5 N: 4.5 inches, Clarence: 4.0 inches, Natchitoches: 3.0 inches, 3 NW Robeline: 3.0 inches, Melrose: 2.5 inches, 5.7 ENE Campti: 1.5 inches. ||Sabine Parish: 1 N Zwolle: 6.0 inches, Converse: 5.5 inches, Ebarb: 4.1 inches, Many: 3.0 inches.

A vigorous upper level shortwave trough shifting northeast across Oklahoma into the Ozarks during the evening through the early morning hours of November 24th-25th, drove a surface frontal system through the Southern Plains. Large scale forcing ahead of the trough and cold front produced a line of strong thunderstorms that moved east through the Four State Region during the evening and overnight hours. Strong instability and forcing resulted in these storms exploding vigorously to the west over North Texas early in the evening, producing some severe wind gusts even as the storms moved into portions of East-central Texas. These storms gradually weakened as they pushed through the remainder of East Texas, but strengthened as they moved into Northwest Louisiana (including Shreveport) after 2 am, where 60 mph winds were measured and downed trees and power lines across portions of Caddo, Bossier, Webster, and Bienville Parishes. These storms weakened further just before daybreak on the 25th as they moved across Northcentral Louisiana.

Hot and humid conditions continued from the final day in August through the first day of September, with temperatures climbing into the mid 90s across Northwest Louisiana. Oppressively high dewpoints in the mid to upper 70s in wake of a warm frontal passage on August 31st shifted back north across much of East Texas and North Louisiana, which when combined with the very hot temperatures, resulted in heat indices ranging from 100-110 degrees across these areas. This was brief though before scattered showers and thunderstorms and associated cloud cover ahead of a closed upper low pressure system over the Four Corners Region affected Northwest Louisiana on the 2nd, resulting in slightly cooler conditions with lower heat indices. Due to the extensive power outages across much of Northwest Louisiana in wake of Hurricane Laura, the NWS Shreveport Heat Advisory criteria was temporarily lowered to heat indices greater than or equal to 100 degrees for parishes where at least 10% of the parish was without power.

Within a few days in the aftermath of Hurricane Laura, hot and humid conditions lingered across Northwest Louisiana from August 30th-31st, as afternoon temperatures climbed into the lower to mid 90s each day. A weak surface frontal passage moved through the area during the early morning hours of the 29th, resulting in slightly drier air to filter into the area. However, these temperatures combined with the humidity contributed to heat indices ranging from 100-103 degrees on the 30th across Caddo and Bossier Parishes, and 105-110 degrees on the 31st. Due to the extensive power outages across much of Northwest and North-central Louisiana in wake of Laura, the NWS Shreveport Heat Advisory criteria was temporarily lowered to heat indices greater than or equal to 100 degrees for parishes where at least 10% of the parish was without power in wake of Hurricane Laura.

Major Hurricane Laura tracked north northwest across the Central and Northern Gulf of Mexico from the Central Carribean Sea near Cuba, making landfall in Southwest Louisiana near Cameron around 1 am on August 27th as a strong Category 4 hurricane with maximum sustained winds near 150 mph, and a minimum central pressure of 938 mb. Laura remained a hurricane as it tracked north across Southwest and Central Louisiana and into Natchitoches Parish, before weakening to a tropical storm as it moved northeast across North-central Louisiana and South-central Arkansas. A combination of observed and estimated wind gusts ranged from 50-90+ mph, resulting in numerous to widespread downed trees and power lines over these areas throughout the morning and early afternoon, before winds weakened by mid-afternoon with the departure of Laura into Southern Arkansas. Widespread rainfall amounts of 2-6 inches was observed across North Louisiana, with higher amounts of 6-8+ inches recorded across Southern and Western DeSoto, Sabine, Natchitoches, Western Grant, Winn, Jackson, and Eastern Bienville Parishes. Flooding was mostly confined to Natchitoches and Western Caddo Parishes.||Here are the peak wind gusts at various automated stations across the affected areas of North Louisiana: ||Gum Springs RAWS (Winn Parish), 70 mph (Incomplete data due to power failure) |Natchitoches (Natchitoches Parish), 66 mph (Incomplete data due to power failure)|Shreveport Regional Airport (Caddo Parish), 66 mph |Monroe (Ouachita Parish), 62 mph (Incomplete data due to power failure)|Ouachita Christian School (Ouachita Parish), 62 mph |Benton (Bossier Parish), 61 mph|Mansfield (DeSoto Parish), 59 mph |Shreveport Downtown Airport (Caddo Parish), 58 mph|Red River Research Station (Bossier Parish), 58 mph |Catahoula RAWS (Grant Parish), 56 mph (Incomplete data due to power failure)|The University of Louisiana-Monroe, Hanna Hall (Ouachita Parish), 55 mph |Bossier City, Barksdale Air Force Base (Bossier Parish), 55 mph |South Bossier City, LSU Research Station (Bossier Parish), 48 mph|Ruston (Lincoln Parish), 44 mph (Incomplete data due to power failure) ||During the peak of the widespread power outages shortly after Laura's center of circulation exited North Louisiana during the afternoon of the 27th, 136,000 customers were without power in Western Louisiana, East Texas, and Southwest Arkansas, with nearly 108,000 Entergy customers without power across North-central and Northeast Louisiana, as well as South-central Arkansas.||Preliminary damage estimates from the LSU AgCenter indicate that Hurricane Laura caused $525.4 million in damage to Louisiana farmers, and $1.1 billion to the Louisiana timber industry, more than Hurricanes Katrina and Rita combined in 2005. Grant Parish alone was 4th in the state with the amount of timber lost, with over $111 million. Entergy reported that Hurricane Laura caused $1.7 billion to its infrastructure throughout Louisiana. ||Here are the known damage across various parishes affected in North Louisiana: ||Caddo Parish: Numerous trees and power lines down parishwide, including the city of Shreveport. Homes were sporadically damaged across the parish from fallen trees. A large tree fell on a home on Ratcliff Drive in Shreveport, causing extensive structural damage and injuring one person. Trees also fell on homes across various locations in Shreveport including West Montego Lane, Tynneside Way, Burgandy Oaks Drive, Nona Circle, and Centenary Blvd, with a large pine tree falling/crushing a truck on Midvale Drive near Ridgewood Drive. A metal building behind a large church in Meriweather Road near West 70th Street has half of its roof peeled off. The shoulder of Interstate 20 at Exit 5 in Greenwood was flooded. ||Bossier Parish: Numerous trees and power lines down parishwide. Homes were sporadically damaged across the parish from fallen trees. ||DeSoto Parish: Numerous trees and power lines down parishwide. A metal roof was damaged on a home in Mansfield. ||Red River Parish: Numerous trees and power lines down parishwide. Power outages to nearly 100 percent of parish residents. ||Bienville Parish: Numerous trees and power lines down parishwide. Power outages to nearly 100 percent of parish residents. ||Webster Parish: Numerous trees and power lines down parishwide. Over 220 reports of incidents from trees down across the parish. The roof was partially blown off of the El Jimador restaurant in Minden.||Claiborne Parish: Numerous trees and power lines down parishwide. Power outages to nearly 100 percent of parish residents. ||Lincoln Parish: Scattered tree damage across most of the parish with more sporadic damage across the western portions of the parish. Tree damage mostly occurred from uprooted trees, with some tree trunks snapped. A tree was blown down onto a home in Ruston. The awning of an Exxon gas station was blown off along Highway 167 north of Ruston. Power outages to nearly 100 percent of parish residents. ||Union Parish: Numerous trees and power lines were down parishwide. Power outages to more than 90 percent of parish residents. ||Ouachita Parish: Numerous trees and power lines down parishwide. Power outages to nearly 80 percent of parish residents. Some trees fell on homes in West Monroe and Monroe. The awning at a Chevron gas station in West Monroe was significantly damaged. The damage and power outages led to the cancellation of classes at the University of Louisiana-Monroe for the following week. ||Jackson Parish: Numerous trees were down across the parish, particularly across the southern portion of the parish and to exposed areas along Caney Creek Reservoir in the Jimmie Davis State Park. One tree fell into a single wide mobile home and killed a 51 year old male on Ayres Loop in Jonesboro. The sustained winds bent trees and the brief stronger winds gusts helped contribute to the tree snaps in the Jimmie Davis State Park. The tree falls generally ranged from the southwest to west-southwest. Power outages to nearly 100 percent of parish residents. ||Caldwell Parish: Multiple trees and power lines down on Highway 4 West between Wiles Road and Mount Pleasant Road, as well as others areas throughout the parish. ||Winn Parish: Scattered to widespread tree damage across the parish, particularly across the central and western portions of the parish which were impacted by the eastern edge of Laura's center of circulation. The tree damage in Winnfield was significant with mostly uproots and some snaps. A few incidents of structural roof damage not caused by downed trees was observed. The tree fall ranged from the northwest to the southwest. Power outages to nearly 100 percent of parish residents. ||La Salle Parish: Scattered to numerous tree damage throughout the parish. A few incidents of structural damage not caused by downed trees were observed in Jena. The Jena High School Gymnasium lost a significant portion of its roofing material, with some damage to signs in front of the school. The awning covering a portion of the parking lot of a local Jena business was destroyed. Trees were also blown down onto homes and vehicles in Jena. The tree fall ranged from the northwest to northeast as the center of Laura's circulation passed just west of the parish. Power outages to nearly 100 percent of parish residents. ||Grant Parish: Scattered to widespread tree damage in the parish, particularly across the central and western portions of the parish which were impacted by the eastern edge of Laura's circulation. A few incidents of structural damage not caused by downed trees were observed, particularly around Dry Prong where a cluster of metal building systems lost a significant portion of roof panels. The most concentrated tree damage (and related home and electrical infrastructure damage related to tree fall) occurred between Dry Prong and the Bentley community along Rob Wallace Road. The tree fall ranged from the west through the northeast, suggesting wind damage was occurring both preceding and in wake of Laura's center of circulation. Power outages to nearly 100 percent of parish residents. ||Natchitoches Parish:Scattered to widespread tree damage in the parish, particularly across the southern and eastern portions of the parish which were impacted by the northern and eastern edge of Laura's center of circulation. The most concentrated damage observed was in Cloutierville and Natchez and locations between these communities along the Cane River. In Cloutierville, hardwood and softwood trees were snapped and uprooted around many homes. In Natchez, most trees were uprooted, while some were snapped. The roof was blown off of the Police Dept. in Robeline. Interstate 49 was closed near Highway 174 due to a fallen tree across the interstate at mile marker 154. Power outages to nearly 100 percent of parish residents. Widespread flooding was reported across much of the parish. Widespread flooding was observed across many areas of the parish. ||Sabine Parish: Scattered tree damage across most of the parish with more widespread damage across the southeastern corner of the parish and exposed areas to the open waters of Toledo Bend Reservoir in the far southwest part of the parish. Damage included snapped trees, roof damage to an apartment complex, and clusters of uprooted trees. The tree fall throughout the parish ranged from south to south-southeast. Power outages to nearly 100 percent of parish residents.

Warm, moist, and unstable air surged north into East Texas, North Louisiana, and Southern Arkansas during the evening through the early morning hours of April 11th-12th, along a warm front that lifted north across much of East Texas into North Louisiana. Meanwhile, a strong upper level low opened up into a trough as it entered the Southern Plains during the evening of the 11th, with large scale forcing ahead of the trough enhancing shower and thunderstorm development across much of West-central, Central, East and Southeast Texas during the evening through the early morning hours. Given the extent of shear, instability, and upper level forcing in place across the warm sector, numerous showers and thunderstorms developed over these areas, which quickly spread east northeast into East Texas around and shortly after daybreak on the 12th, and into North Louisiana during the mid and late morning hours. Some of these storms were severe, producing numerous reports of damaging winds, large hail, and tornadoes. In all, nine tornadoes touched down across North Louisiana, including two EF-3 tornadoes with estimated maximum winds near 140 mph which tore through the southern sections of West Monroe through Central and Eastern Monroe, as well as just southwest of Sterlington in Northern Ouachita Parish. ||While there was a lull in the thunderstorms during much of the afternoon, additional strong to severe thunderstorms developed across portions of Northeast Texas well behind the dry line which had mixed east to near Texarkana into Western Louisiana, and near the center of the upper level trough. Steep lapse rates aloft and the drier low level air mass contributed to areas of damaging winds and isolated instances of large hail, with the majority of the wind damage from a collapsing thunderstorm which originated just east of Dallas, and quickly moved east along the I-20 corridor in East Texas into Western Louisiana. Aided by strong pressure rises behind an associated cold front, a large swath of damaging winds were noted with the severe gust front, with gusts ranging from 50-70 mph well ahead of the collapsed storm. This resulted in numerous reports of downed trees and power lines across East Texas and Western Louisiana, with AEP Swepco noting that over 64,000 customers were without power at one time in the aftermath of the storms. These damaging winds diminished across Western Louisiana by mid-evening.

An upper level longwave trough emerged out of the Intermountain West and into the Central and Southern Plains during the daytime and evening hours of January 10th. A strong southerly return flow commenced out ahead of the trough during the 8th-9th, allowing for unseasonably warm and humid conditions to advance northward across Southern Oklahoma, much of Central and Eastern Texas, as well as Louisiana, Arkansas, and the Lower Mississippi Valley. Meanwhile, an intensifying surface low pressure system and associated dry line developed along the Red River of North Texas into Southern Oklahoma during the afternoon hours, which spread east northeast across the Ark-La-Tex during the early morning hours on January 11th. With afternoon temperatures climbing into the mid 70s ahead of this trough, moderate instability developed across the broad warm sector, with very strong wind shear in place as large scale forcing increased ahead of the trough axis across East Texas, Southeast Oklahoma, Southwest Arkansas, and North Louisiana. Thus, an axis of strong to severe showers and thunderstorms developed during the evening hours across Southeast Oklahoma, adjacent sections of Southwest Arkansas and East Texas, which advanced east into North Louisiana during the early morning hours of the 11th. Widespread damaging winds downed trees and power lines across much of Northwest and Northcentral Louisiana, with even a long track tornado developing along the line of severe thunderstorms across Central Bossier, Southern Webster, and Southern Claiborne Parishes. Another isolated tornado touched down in Western Union Parish, before these storms exited the region shortly before daybreak on the 11th. Unfortunately, these storms resulted in four fatalities across Northwest Louisiana, three of which occurred from the Haughton tornado.

A longwave trough dug south into the Southern Plains during the daytime hours of October 20th, with southerly winds increasing ahead of the trough helping to return low level moisture north from the Gulf of Mexico. Above normal temperatures were seen across much of the region as readings climbed into the mid 80s to near 90 degrees, which enhanced instability during the late afternoon through the evening hours across much of the Ark-La-Tex area. Wind shear increased during the evening, with an isolated supercell thunderstorm developing over Central Cherokee County Texas, which tracked northeast across Central Rusk, Western and Northern Panola Counties, and into the Shreveport/Bossier City areas of Northwest Louisiana before weakening. This supercell produced a tornado across Western Panola County Texas, with numerous reports of damaging winds which downed trees and power lines, as well as hail before diminishing over the east side of Bossier City in Northwest Louisiana. Additional strong to severe thunderstorms developed during the late evening through the early morning hours on October 21st across Northeast Texas, Southeast Oklahoma, Southwest Arkansas, and North Louisiana ahead of this trough and associated strong cold front, as wind shear increased within a still unstable environment. These storms produced numerous reports of damaging winds across these areas, before diminishing shortly after daybreak with the departure of this system.

An upper level ridge of high pressure anchored over the Southeast United States allowed for a deep southerly flow from the Gulf of Mexico across East Texas and North Louisiana on June 26th. This resulted in a large area of scattered showers and thunderstorms associated with a strong seabreeze to push north across these areas from the coast during the afternoon and early evening. Strong daytime heating and ample low level moisture in place enhanced instability across Northwest Louisiana as these storms lifted north, with isolated severe thunderstorms developing by early evening over Southern Caddo Parish. These storms produced damaging winds which downed trees and power lines across West and Northwest Shreveport before diminishing by mid-evening.

With the departure of an upper level ridge that resulted in oppressive heat across the Ark-La-Tex area in the preceding days, the upper flow aloft became more southwest during the daytime hours on June 23rd, ahead of an upper level trough and associated cold front that shifted east southeast across Oklahoma and Arkansas. Scattered to numerous showers and thunderstorms developed by mid and late afternoon across portions of East Texas and North Louisiana ahead of this upper trough and associated cold front, where the air mass destablized significantly given the hot and humid air mass in place. Some of these storms were severe, which downed trees and power lines during the mid and late afternoon hours. Meanwhile, the remnants of a mesoscale convective system (MCS) that moved across Southern Kansas and Northern Oklahoma earlier that morning helped to initiate another complex of showers and thunderstorms by early evening over Southeast Oklahoma and Southwest Arkansas, which intensified across portions of East Texas, Southwest Arkansas, and North Louisiana during the evening through the early morning hours of June 24th. Some of these storms were also severe, producing damaging winds which also downed more trees and power lines across portions of North Louisiana.

A weakening complex of showers and thunderstorms entered portions of Northeast Texas during the pre-dawn hours of June 19th, but a strong southwesterly low level jet feeding into these storms interacted with adequate instability still in place for these storms to re-intensify over portions of East Texas, such that they became severe producing damaging winds that downed trees and power lines, which eventually spread into portions of Northwest Louisiana before weakening again shortly after daybreak. ||This complex of thunderstorms left behind a surface boundary which lifted north across Northeast Texas, Southeast Oklahoma, and Southwest Arkansas ahead of an approaching upper level shortwave trough. Strong heating near this surface boundary resulted in the development of moderate instability, with large scale forcing ahead of the approaching trough contributing to the development of a second round of severe thunderstorms during the late afternoon and evening hours across East Texas, which eventually spread into Northwest Louisiana by late evening just prior to midnight. The storms produced damaging winds across Caddo and Bossier Parishes, and even a brief tornado touchdown in Northern Bossier Parish, before finally weakening during the early morning hours of June 20th.

A moist and unstable airmass was present during the afternoon and evening hours of March 13th across portions of Northcentral and Northeast Louisiana. A dryline moved rapidly eastward across Northern Louisiana during the day with showers and thunderstorms erupting along and ahead of this feature. Upper level forcing was present due to a vigorous upper level trough which moved into the Plains earlier in the day. Very strong winds were present in the lower and mid levels of the atmosphere across the Lower Mississippi Valley and a few storms that developed ahead of the dryline across Northeast Louisiana took on supercell characteristics. Damaging wind gusts were reported with one of these storms across Eastern Union Parish Louisiana with a report of trees downed east of Farmerville.||During the early morning hours of March 14th, a line of strong to severe thunderstorms developed along a cold front across Eastcentral Texas along the base of the upper level trough, and marched east into Northwest Louisiana after 330 am. These storms produced damaging winds which downed trees and power lines across portions of Caddo and Claiborne Parishes before weakening prior to daybreak.

An upper level trough amplified during the daytime hours of October 31st across much of the Plains and Southern Rockies, which reinforced a strong cold front southeast into the Southern Plains. Ahead of this front and accompanying trough, above normal temperatures ranging from the mid 70s to lower 80s coupled with increased low level moisture resulted in a moderately unstable air mass during the afternoon. The pressure gradient tightened across the warm sector which expanded across much of the Ark-La-Tex, well ahead of the front as surface low pressure intensified along the frontal surface over North Texas. This enhanced wind shear as the front advanced east across much of Texas and Southeast Oklahoma, with large scale forcing ahead of the trough contributing to scattered shower and thunderstorm development during the afternoon over Southeast Oklahoma, Southwest Arkansas, and Central Texas. Some of these storms became severe of portions of Southwest Arkansas and extreme Northeast Texas, with a squall line developing farther west over Central Texas by mid and late afternoon, which quickly advanced east across much of East Texas and North Louisiana during the late afternoon and evening hours. Several reports of wind damage which downed trees and power lines were received across East Texas and Northwest Louisiana. This squall line weakened as it progressed east across Northcentral Louisiana, but a discrete supercell thunderstorm developed out ahead of the main line over Southwest Rapides Parish Louisiana, and spawned a nearly 40 mile long track tornado that remained on the ground from just southwest of Alexandria and across Southeast Grant and Central La Salle Parishes just prior to and shortly after midnight on November 1st. These storms quickly exited the southeast sections of Northcentral Louisiana by 2 am on the 1st, but not before spawning additional tornadoes and widespread wind damage across much of Mississippi.

Remnants of a Mesoscale Convective System (MCS) shifted southeast across Southeast Oklahoma, Southwest Arkansas, and extreme Northeast Texas during the morning hours of July 29th, as a shortwave trough dropped southeast from Oklahoma into Arkansas and the Lower Mississippi Valley. While this complex of showers and embedded thunderstorms entered the region as non-severe, they gradually intensified as they moved across extreme Southern Arkansas and North Louisiana, in response to an unstable atmosphere that developed due to strong daytime heating as temperatures climbed to the mid and upper 90s. As a result, scattered severe thunderstorms producing damaging winds downed trees and power lines over extreme Southern Arkansas, before they spread southward across much of North Louisiana during the mid and late afternoon hours. These storms exited the area and weakened with the loss of heating once they moved into Central and Southern Louisiana.

An upper level ridge of high pressure was anchored across the Mississippi Valley west into the Central Plains during the afternoon of July 5th, with weak impulses aloft in the easterly flow interacting with strong diurnal heating to generate isolated to widely scattered showers and thunderstorms across Northwest Louisiana and portions of East Texas. Given the strong instability that had developed that afternoon, isolated storms became severe, which resulted in damaging winds downing a tree and power lines near Shreveport and Blanchard before diminishing during the evening with the loss of heating.

An upper level trough of low pressure shifted east from the Ohio Valley southwest across the Midwest and Central/Southern Plains during the late morning hours of September 5th. The accompanying cold front moved into Southwest Arkansas and extreme Northeast Texas during the mid and late afternoon, before moving into North Louisiana during the evening. Moderate instability developed along and ahead of the front, with increasing frontal convergence yielding scattered to numerous showers and thunderstorms during the late afternoon and evening across Southwest Arkansas and North Louisiana, where large scale forcing was strongest ahead of the trough. Some of these storms became severe, resulting in downed trees and power lines across portions of Northwest and Northcentral Louisiana. These storms began to diminish by mid to late evening as cooler and drier air began to spill south in wake of the frontal passage.

Scattered showers and thunderstorms developed during the afternoon and evening hours across East Texas, Southern Arkansas, and much of North Louisiana, near a stationary front that extended from near the Red River of North Texas into Northeast Texas and North Louisiana. Moderate instability developed as afternoon temperatures climbed into the mid 90s, with abundant moisture in place with the passage of a weak upper level disturbance atop the front. Strong thunderstorms developed over Eastern Harrison County Texas which moved southeast and intensified across Southwest and southern Caddo Parish and across much of Red River Parish in Northwest Louisiana. This resulted in a wide swath of damaging winds of 60-70 mph across these areas, which downed numerous trees and power lines before weakening as they moved into Natchitoches Parish.

Afternoon heating and moderate to high instability across the Lower Mississippi Valley resulted in widely scattered strong to severe thunderstorms across Northwest Louisiana during the late afternoon and early evening hours of July 6th. As these storms decayed, they produced outflow boundaries for additional convection to develop on. One of these storms produced a destructive cold pool boundary that moved directly over Shreveport, Louisiana. The result was numerous trees and powerlines downed across the city. The storms continued to move south and east into the early evening hours downing additional trees in DeSoto Parish.

Overnight showers and thunderstorms which held together into the morning hours of Sunday May 28th, moved into Northern Louisiana from the northwest during the morning hours after daybreak. Isolated severe thunderstorms developed near Bossier City during the mid-morning hours, producing numerous reports of penny to quarter size hail. These storms mostly dissipated by midday, leaving numerous outflow boundaries across the area. Meanwhile, a warm front moving northward into the area resulted in dew points quickly rising from the mid 60s to the mid 70s with its passage. This front stalled out near the Interstate 30 corridor of Northeast Texas, and south of this boundary, scattered thunderstorms quickly developed by mid-afternoon and spread east across East Texas near and south of the Interstate 20 corridor. These storms rapidly intensified during peak afternoon heating and instability, and produced numerous reports of wind damage across extreme Eastern Texas and North Louisiana. |In addition to widespread straight line winds which exceeded 80-90 mph at times as they organized into a large scale bow echo, isolated tornadoes also touched down south and east of Natchitoches. Training storms moving west to east also producing brief flash flooding at some locations. These storms overall had only shown very slight weakening trends by the time they entered Central Louisiana after 10 pm that evening. In the storms' wake, over 103,000 customers were left without power across East Texas and Western Louisiana in the AEP SWEPCO coverage area, which was the 4th worst storm (with outages) in the company's 105 year history.

A weak backdoor cold front moved into northern Louisiana from the northeast during the late morning and afternoon hours of June 18th. Scattered to numerous strong to severe thunderstorms formed along and ahead of this backdoor cold front and the storms developed a cold pool which quickly moved westward across the northern half of the state. The atmosphere ahead of this frontal boundary was moderately unstable but once the cold pool developed...trees and powerlines fell as a result of these thunderstorms.

An outflow boundary from showers and thunderstorms that developed over Southwest Oklahoma during the evening and overnight hours on April 10th became stationary over Northern McCurtain County Oklahoma into the adjacent sections of Western Arkansas during the early morning hours of April 11th. This boundary focused scattered shower and thunderstorm development through the morning of the 11th, with large scale forcing enhanced especially during the afternoon and evening hours as a weak upper level trough traversed the Red River Valley of Southern Oklahoma/North Texas into Southwest Arkansas. Afternoon heating and cooling temperatures aloft ahead of this disturbance contributed to moderate instability developing especially over Southeast Oklahoma, Northeast Texas, and portions of Southwest Arkansas, contributing to the development of several severe thunderstorms over these areas. Damaging winds were the primary severe weather mode over Southwest Arkansas, with numerous trees and power lines downed especially across the south side of Texarkana Texas and Arkansas, as well as adjacent Lafayette and Columbia counties. As the storms moved into a slightly more stable air mass across Northcentral Louisiana, they began to slow their southward motion such that heavy rainfall repeatedly moving over the same areas resulted in areas of flash flooding generally along and north of the Interstate 20 corridor.

With a very cold atmosphere already in place, an upper level storm system moved out of the Texas Hill Country and into Northeast Texas, Southwest Arkansas and Northwest Louisiana during the afternoon hours of February 11th. Precipitation became widespread across the region late in the afternoon and especially during the overnight hours of February 11th and the 12th. During the onset of precipitation, a mixture of rain and sleet was the predominant precipitation type with some sleet accumulations exceeding one inch across portions of Northwest Louisiana. There was even a brief transition of moderate snow across portions of the region as well. During the evening and overnight hours of the event, the transition turned to predominantly freezing rain with some hefty accumulations noted across the region. Ice accumulations of one quarter of an inch were common across much of Northwest Louisiana with totals of one half inch common across some parishes in Northeast Louisiana. These higher ice accumulation totals were noted across Union, Lincoln, Ouachita, Jackson and Caldwell Parishes. Impacts included numerous automobile accidents, downed trees and powerlines as well as thousands without power across the northern half of the state.

A shallow cold layer of air moved out of the Southern Plains and into the Lower Mississippi Valley on the 24th of November. The flow aloft across the southern portion of the country was from the southwest. This resulted in an overrunning pattern of warm and moist air overrunning the cold shallow subfreezing air. The end result was a period of freezing rain and sleet across portions of Northwest Louisiana, mainly north of the Interstate 20 corridor of Northern Louisiana. Ice accumulation was mostly less than one quarter of an inch. Temperatures were well above normal before this airmass settled into the region so the ice accumulation was mainly on elevated objects such as bridges, overpasses, trees, powerlines and car tops.

Showers and thunderstorms moved across the region during the morning hours of June 18th as well as the afternoon and evening hours. These storms trained across the same general area and produced copious amounts of rainfall, some of which produced flash flooding. Some of these storms became linear in nature and downed trees and powerlines as they moved east.

Three supercell thunderstorms developed during the early afternoon hours on the 30th over extreme Eastern Texas and North Louisiana, several hours after scattered showers and thunderstorms spread across the region. The thunderstorms developed along a pair of surface boundaries leftover from the morning convection, with adequate shear and afternoon heating contributing to moderate instability. One supercell developed over Bowie County Texas and produced damaging winds which downed power lines while also producing copious amounts of small hail which covered the ground. The second supercell developed over Cass County Texas, and moved into Caddo, Desoto, and Sabine Parishes in Northwest Louisiana. This storm produced a large swath of dime to golfball size hail and damaging winds which blew down trees and power lines as it tracked across West and South Shreveport and the east side of Stonewall. The hail fell for nearly 10 minutes across Shreveport, and covered the ground from several inches up to a foot deep over South Shreveport. The third supercell developed over southwest Jackson Parish, which produced damaging winds which downed trees in Jonesboro, Louisiana.

A strong cold front moved through Northwest Louisiana during the evening hours of January 13th and the predawn hours of January 14th. Rain and a few storms accompanied the passage of this cold front across the northern half of the state. A very cold airmass filtered in behind the frontal boundary. Meanwhile, weak disturbances moved towards the state from the west and with plenty of moisture still in place, overrunning precipitation developed during the morning and afternoon hours of January 15th. With surface temperatures near or slightly below freezing, the precipitation fell as a mixture of freezing rain and sleet. Only light ice accumulations from the freezing rain and sleet were noted across Northwest Louisiana, mainly less than one quarter of an inch. Some bridges and overpasses quickly became slick resulting in several automobile accidents across the northern half of the state. In addition, there were some minor power outages from falling limbs due to the weight of the ice.

A strong cold front moved through Northwest Louisiana during the evening hours of January 13th and the predawn hours of January 14th. Rain and a few storms accompanied the passage of this cold front. A very cold and shallow airmass followed the cold front yet southwesterly winds overran this cold shallow airmass above five thousand feet in the atmosphere. Meanwhile, weak disturbances moved towards the state from the west and with plenty of moisture still in place, overrunning precipitation developed during the morning of January 14th. With surface temperatures near or slightly below freezing, the precipitation fell as a mixture of sleet with some freezing rain noted as well. Accumulations were very light, mainly less than a tenth of an inch for the event. Regardless, bridges and overpasses quickly became slick resulting in several automobile accidents across portions of Northeast Texas. In addition, there were some minor power outages from falling limbs due to the weight of the ice.

A large outflow boundary initiated by previous showers and thunderstorms over northern Arkansas during the day Monday spread south into the Four State Region during the late afternoon and evening. This boundary helped with the development of showers and thunderstorms that interacted with other isolated and smaller scale outflow boundaries to produce scattered strong to severe thunderstorms that contained locally heavy rainfall, frequent and continuous lightning strikes, and gusty winds of 30 to near 45 mph and isolated higher gusts. These gusts downed trees and power lines. Daytime temperatures were near the century mark Around nightfall the storms went into a decreasing cycle with loss of the afternoon heating. However, during the evening, remnants of a sea breeze boundary spread north across parts of East Texas and lower Northwest and North Central Louisiana and collided with the south bound boundary, allowing storms to increase in intensity as they moved across parts of Louisiana just prior to midnight.

A significant winter storm affected the northern half of Northwest and North Central Louisiana on Sunday, January 9th. This storm system moved out of the Texas Hill Country late on January 8th and moved into the Southern Plains and Lower Mississippi Valley during the day Sunday, January 9th. An area of low pressure at the surface and in the lower levels of the atmosphere developed offshore the Southeast Texas Gulf Coast and remained offshore the Louisiana Gulf Coast during the day of the event. This low pressure system helped to feed moisture into the region from the south. Initially, the lower levels of the atmosphere were very dry, but lift provided by the storm system helped to moisten and cool the lower levels of the atmosphere such a combination of freezing rain, sleet and snow were the result across the northern half of Northwest and North Central Louisiana. While snowfall totals were on the light side, freezing rain and sleet totals ranged from one quarter to one half inch along and north of the Interstate 20 corridor of northern Louisiana with a few reports of snow near one inch across extreme Northwest Louisiana. The following are freezing rain reports across Northwest and North Central Louisiana: one half inch in Benton, Homer, Ruston and Farmerville, one quarter of an inch in Shreveport, Bienville, and Monroe. In addition to the freezing rain, sleet and snow totals were as follows: one inch in Shreveport, Bossier City, Benton and Springhill. There were numerous reports of traffic accidents across Northwest and North Central Louisiana, including 3 vehicular fatalities across the northern half of the state. There were also reports of isolated power outages.

A large upper level ridge dominated a large portion of the southern plains but there was a weakness in the ridge across the Lower Mississippi Valley on Sunday, June 21st. With extreme heating which developed during the afternoon and early evening hours of the 21st, isolated strong to severe thunderstorms developed across portions of northeast Louisiana as well as north central and northwest Louisiana. These storms developed in an airmass where temperatures reached the century mark during the afternoon...resulting in a very unstable airmass. These storms produced downburst type winds which downed trees and powerlines across the region.

A complex of strong thunderstorms developed across southeast Texas during the early morning hours of June 8th. These storms propagated northward along a strong outflow boundary and moved into northeast Texas and northwest Louisiana. A very unstable atmosphere awaited this line of storms and during the afternoon, a few reports of downed trees and powerlines were reported across northwest Louisiana.

Hurricane Gustav moved northwestward into the southeast Louisiana coast during the early morning hours of September 1st. The storm continued a steady northwestward motion into east central Louisiana and northwest Louisiana during the evening hours of September 1st. The storm was downgraded to a tropical storm just before entering east central Louisiana during the late evening hours of September 1st. As the storm continued to move to the northwest...tropical storm force winds affected much of east central and west central Louisiana which downed numerous trees and power lines. Power was out across many locations and several trees fell on top of homes and automobiles. Wind gusts likely approached 70 mph in a few locations during the evening and late night hours of September 1st into the pre dawn hours of September 2nd.

A complex of severe thunderstorms developed across northwest Mississippi and moved west southwest into the region...downing numerous trees and powerlines across north central and northeast Louisiana. A gust front developed ahead of the convection and preceded the convection by in some cases 10 to 15 miles. This outflow boundary or gust front produced winds approaching 50 mph which downed trees and powerlines as well. The storms propagated into a very unstable airmass during the late night hours of August 2nd and continued into the early morning hours of August 3rd.

Strong low level winds nearing 60 knots at approximately four thousand feet in the atmosphere mixed down to the surface during the afternoon of March 18th. These winds, not associated with thunderstorms, resulted in widespread trees and power lines down across portions of northeast Texas as well as northwest Louisiana during the afternoon of the March 18th.

Hurricane Rita came on shore across the Southeast Texas/Southwest Louisiana coast and moved north northeast across East Central Texas and Northwest and North Central Louisiana during the morning and afternoon hours of September 24, 2005. The storm weakened as it moved northward, however, all of Northwest and North Central Louisiana remained on the east side of the eyewall and experienced strong tropical storm force winds. Damage was sporatic across the region with damage consisting of downed trees and powerlines as well as structural damage to homes, businesses and automobiles from downed trees. The damage was particularly extensive along and near the Toledo Bend Reservoir of West Central Louisiana where several structures suffered minor to moderate damage. Many residents of Northwest and North Central Louisiana lost power during the height of the storm. A monetary amount was not available at the time of this report.
