Police officers were needed to direct traffic until crews from the Public Works Department could install stop signs at intersections.

A line of thunderstorms developed ahead of an approaching cold front during the afternoon across western Wisconsin and tracked through northeast Wisconsin through the evening hours on Wednesday (6/15). The storms formed into a Quasi-Linear Convective System (QLCS) with multiple reports of damaging winds of 70 to 80 mph as well as 10 tornadoes embedded within the main line of thunderstorms. The 10 tornadoes ties a record for the most tornadoes in an event for northeast Wisconsin. Additional storms late in the evening produced a few reports of large hail near the lakeshore as they moved offshore. ||The swath of damaging winds caused multiple power outages, with over 125,000 customers without power across northeast Wisconsin. Power was not restored for several days across many areas as the cleanup from the storms took an extended period of time.

The second winter storm in a week struck during the Thanksgiving weekend, impacting Wisconsin from late Saturday evening November 30th through Sunday December 1st. The storm developed over the Central Plains early Saturday, then quickly moved east to the Wisconsin/Illinois border on Sunday. Warm air aloft brought a mix of rain, sleet, freezing rain, and snow to the area Saturday afternoon and Saturday evening, transitioning to all snow by Saturday night and continuing into Sunday. A band of 8 to 12 inches fell across northern Wisconsin, with some areas receiving as much as 14 inches of snow. Farther south, snowfall totals were lower, in the 4 to 8 inch range; however, gusty winds caused some downed trees and power outages across the region. The combination of high bay and lake water levels and strong northeast winds also caused considerable flooding along the bay and lake.||Some of the higher snowfall totals included 14.0 inches in Wausaukee (Marinette Co.), 13.5 inches near Mountain (Oconto Co.), 13.4 inches in Florence (Florence Co.), 12.2 inches in Washington Island (Door Co.), 12.1 inches in Crivitz High Falls (Oconto Co.), 11.6 inches in White Lake (Langlade Co.), and 11.3 inches near Argonne (Forest Co.) as well as Rice Reservoir (Lincoln Co.).

A strengthening low pressure system developed over the central Plains and moved northeast to Lake Michigan, bringing 10 to 14 inches of heavy snow, and occasionally sleet, to northern and portions of central Wisconsin. The wet, heavy snow accumulating on trees and power lines, along with strong winds, caused widespread power outages across much of northern Wisconsin with over 40,000 residences impacted. The combination of strong winds and high water levels caused flooding along the shoreline of the Bay of Green Bay and Lake Michigan.||Some of the highest snowfall totals included 14.8 inches near Land O' Lakes (Vilas Co.), 14.1 inches in Eagle River (Vilas Co.), 13.5 inches in Hazelhurst (Oneida Co.), 12.7 inches in Phelps (Vilas Co.), 11.6 inches in Rhinelander (Oneida Co.), 11.0 inches west of Merrill (Lincoln Co.), 10.8 inches in Minoqua (Oneida Co.), and 10.0 inches in Summit Lake (Langlade Co.).

Severe thunderstorms formed in very unstable air ahead of a passing cold front. The worst of the damage from the storms occurred across east-central and parts of northeast Wisconsin. Thunderstorm winds downed numerous trees and some power lines, hail as large as golf balls fell, and a weak tornado touched down on the east side of Green Bay (Brown Co.). Heavy rain led to flooding in parts of east-central Wisconsin as the storms formed an east-west line that slowly moved southeast.

Isolated severe thunderstorms developed as a frontal boundary moved into the area from the northeast and encountered an unstable air mass. The storms caused tree and power line damage and dropped hail as large as penny size.

For the second consecutive day, a line of powerful thunderstorms moved across portions of central and east-central Wisconsin. The worst damage occurred from Wood/Portage counties eastward into the Fox Valley and lakeshore. Trees were uprooted or snapped and several structures were damaged as a result of straight-line winds and six weak, fast-moving tornadoes.||There was also a fatality due to drowning in Keshena (Menominee Co.) from abnormally fast flows on the Wolf River.

A line of severe thunderstorms moved across much of central, north central, and eastern Wisconsin during the evening hours of July 19, 2019. Widespread tree and power line damage was reported from central Wisconsin into the Fox Valley and lake shore. WPS reported over 50,000 outages at the height of the storm.||The worst damage was associated with a macroburst, a large downburst of straight-line winds that affected a large swath from Pelican Lake in Oneida County, southeast through Langlade and Oconto counties. Hundreds of thousands of trees were snapped or uprooted, resulting in damage to dozens of homes and cottages. The damage path was about 60 miles long and up to 10 miles wide at times. Winds were likely near 100 mph in the hardest hit areas near Lily in northeast Langlade County and near the Langlade-Oconto County line southwest of Boot Lake.

Thunderstorms, associated with a long-lived complex, moved across Wisconsin during the late afternoon. The storms downed trees and power lines across parts of central and east-central Wisconsin.

Winds of 45 to 55 mph, associated with a line of showers, downed numerous trees and power lines in parts of central and east-central Wisconsin.

A period of strong winds behind an area of rain resulted in downed trees and power lines. A few gusts of 50 mph or greater downed several hundred trees, many uprooted in the saturated soil, across north-central and northeast Wisconsin.

A fierce, late-winter storm produced heavy snow, freezing rain, and high winds across much of central and northern Wisconsin on February 23-24 as an area of low pressure rapidly deepened across the Great Lakes. At the height of the storm on the 24th, travel was not recommended across parts of central and northern Wisconsin as blizzard conditions made travel nearly impossible. The combination of ice, snow, and strong winds caused power outages and tree damage in many locations.||Strong winds and near-blizzard conditions shut down a few rural stretches of heavily traveled highways across east-central Wisconsin on February 24, including I-41 in Neenah (Winnebago Co.), where one motorist was killed and 71 others injured in a chain-reaction pileup involving 131 vehicles. This was the largest traffic accident in Wisconsin history.||The accident happened around 11:20 AM CST in the southbound lanes of I-41 at Highway G in Neenah. Cars, pickups, and semitrailers smashed together and sandwiched underneath each other. The interstate wasn't reopened until 3 AM on February 25. ||Some of the highest snowfall totals with the two-day storm included 18.9 inches near Eagle River (Vilas Co.), 16.1 inches at Rice Reservoir (Lincoln Co.), 15.9 inches near Argonne, 15.7 inches near Merrill (Lincoln Co.), 15.4 inches in Rhinelander (Oneida Co.), 12.7 near Boulder Junction (Vilas Co.), and 12.5 in Spread Eagle (Florence Co.). Parts of central and east-central Wisconsin received up to one-half inch of ice accumulation in addition to the snow.||Measured wind gusts in the 50 mph to 60 mph range were recorded at many locations, including: 60 mph in Green Bay (Brown Co.); 58 mph in Wausau (Marathon Co.); 57 mph in Kewaunee (Kewaunee Co.); 56 mph in Omro (Winnebago Co.); 53 mph near Zittau (Winnebago Co.), near Monico (Oneida Co.), in Marshfield (Wood Co.), and in Rhinelander (Oneida Co.); 52 mph in Wisconsin Rapids (Wood Co.) and in Manitowoc (Manitowoc Co.); and 51 mph in Appleton (Outagamie Co.) and in Wautoma (Waushara Co.).||New daily snowfall records were set for February 24 in Rhinelander and Wausau. The 10.9 inches in Rhinelander broke the previous record of 5.8 inches that was set in 2017, and the 7.6 inches in Wausau broke the previous record of 7.3 inches that was set in 2017.

Severe thunderstorms produced wind damage, including a tornado, over east-central Wisconsin. Numerous trees were snapped or uprooted and power lines downed. The storms also produced torrential rainfall that caused urban flooding and flash flooding in parts of the Green Bay area and Fox Valley. There were numerous reports of 2 to 4 inches of rain, along with a few even higher totals.

A low pressure system that moved from the Plains, across Illinois, to the Ohio Valley brought two periods of heavy precipitation and strong northeast winds to the area. The historic late season winter storm pummeled northeast and north-central Wisconsin from the evening of April 13th through the afternoon of April 15th. The storm brought blizzard or near-blizzard conditions to much of the area and made roads impassable from time-to-time. Winds of 35 to 50 mph caused sporadic power outages and created waves of 10 to 16 feet on Lake Michigan. The persistent northeast wind caused shoreline erosion along the western shores of the lake.||New snowfall records were set at many locations as a large area of 15 to 30 inches of snow fell and winds gusted over 45 mph. Some of the highest recorded snowfall totals included, 31.6 inches near Carlsville (Door Co.), 30.6 inches in Tigerton (Shawano Co.), 30.5 inches near Stiles (Oconto Co.), 28.4 inches in Waupaca (Waupaca Co.), 27.5 inches in Peshtigo (Marinette Co.), and 25.5 inches in Suamico (Brown Co.). The strongest recorded wind speeds included 52 mph near Plover (Portage Co.), 51 mph at Marshfield (Wood Co.) and Green Bay (Brown Co.), and 50 mph near Marinette (Marinette Co.) and near Rose Lawn (Shawano Co.).||The heavy weight of the snow caused several structures to collapse or partially collapse, mainly across east-central Wisconsin. Several barn roofs collapsed in Kewaunee County, killing at least 17 cows, and parts of several barn roofs collapsed in Shawano County, resulting in the death of at least 2 cows. A barn roof collapsed near Oconto Falls (Oconto Co.) and another collapsed near New London (Waupaca Co.) killing at least 4 cows. Roofs collapsed, or partially collapsed, on at least 5 buildings in Outagamie County, including a barn in the town of Freedom where 30 cows were injured or killed. The roof of the main arena at a horse therapy center near Neenah (Wnnnebago Co.) partially collapsed. In Brown County, at least 15 businesses, including a motel and a barn, had some sort of roof collapse. Four people were trapped when a barn roof collapsed in Denmark (Brown Co.).||Snowfall totals were the highest ever recorded for an April storm in Green Bay, Appleton, Wausau and Rhinelander. This was the largest snowstorm on record in Appleton (21.2 inches), the second largest snowstorm on record in Green Bay (24.2 inches) and Wausau (20.7 inches), and the third largest snowstorm on record in Rhinelander (18.2 inches).

A large convective system, that moved across Minnesota overnight, continued east and southeast into unstable air across the area. Thunderstorms produced widespread wind damage, downing trees and power lines as they passed. Embedded bowing line segments along the main line of storms caused the worst of the damage. Hail to quarter size fell at a few locations in central Wisconsin.

A line of thunderstorms, from western Upper Michigan into southeast Minnesota, produced widespread damaging winds that downed a large number of trees and power lines as the storms moved into very warm and unstable air. A wind gust to 61 mph was measured at Marshfield Municipal Airport (Wood Co.) as the storms passed and a COOP observer in Plover (Portage Co.) measured a gust to 59 mph. Isolated quarter size hail fell at Hogarty (Marathon Co.) and southwest of Shawano (Shawano Co.), and a brief, weak tornado occurred near Mackville (Outagamie Co.) as the storms passed.

Thunderstorms approaching from the northwest began to produce damaging winds in central Wisconsin as they encountered a more unstable air mass. The storms continued to cause damage as they moved across east central Wisconsin. There was also some nickel size hail with the storms. Thunderstorm winds downed or snapped numerous trees, large branches, and power lines; and wrapped a trampoline around a power pole. The winds and/or fallen trees caused roof damage to a middle school, a house, and a garage. The fallen trees and branches caused severe damage to 3 vehicles. Measured gusts from the storms included 60 mph at Manitowoc County Airport (Manitowoc Co.), 62 mph at Appleton International Airport (Outagamie Co.), and 64 mph at Wausau Downtown Airport (Marathon Co.).

A very strong low pressure system moved across the region during the early morning hours of December 24th. Widespread winds of 35 to 45 mph affected central, north central, and east central Wisconsin. The strong winds blew down some trees, numerous tree branches were knocked down and thousands lost power. Some of the strongest wind gusts included: 59 mph near Whitefish Dunes State Park (Door Co.), 52 mph at Algoma (Kewaunee Co.), 51 mph in Green Bay (Brown Co.), and 46 mph near Appleton (Outagamie Co.).

Thunderstorms that developed ahead of an approaching surface boundary moved south across Wisconsin. Some of the storms produced heavy rainfall that caused minor urban flooding, damaging winds that downed trees and power lines, and hail up to golf ball size across eastern Wisconsin. As the storms moved across southern Lake Winnebago they produced gusts to around 40 mph that caused large waves to quickly develop, capsizing a boat with four people on board. Three of the boat's passengers reached shore while the fourth had to be rescued by the Winnebago County Sheriff's Department.

Another round of severe thunderstorms with large hail and damaging straight-line winds affected parts of central and northeast Wisconsin during the afternoon of August 2nd. The most intense storms developed near a surface boundary that stretched from Wausau to Green Bay early in the afternoon.||Some of the first severe storms of the event developed just north of Green Bay, over parts of Oconto County and Marinette County, and produced hail in excess of three inches in diameter. These storms were part of a larger line of storms that raced eastward across the waters of Green Bay, causing widespread wind damage and knocking out power across much of Door County.||Additional storms developed westward toward the Wausau area. These storms moved southeast during the late afternoon and produced large hail and damaging winds from Marathon and Wood counties east to Lake Michigan.

A thunderstorm complex, that developed in South Dakota on the evening of July 17th, continued eastward and tracked across central and east central Wisconsin during the early morning hours of July 18th. The storm downed numerous trees and power lines and also knocked down tents at an outdoor event in Oshkosh (Winnebago Co.), causing injuries to 2 people.

A line of storms interacted with a warm front over central Wisconsin to produce severe weather. The storms downed trees and power lines, and tore part of the roof from a barn in Hortonville (Outagamie Co.), as they moved across central and east central Wisconsin.

Strong winds blew across east central Wisconsin, producing several measured gusts to around 50 mph, as low pressure passed east of the state. The winds associated with the low may have been enhanced by a gravity wave. The strong winds downed numerous trees, branches, and power lines. More than 14,000 customers were without power at the height of the event.||Some of the strongest measured wind gusts included: 53 mph at Austin Straubel International Airport (Brown Co.), 52 mph at Shawano Municipal Airport (Shawano Co.), and 51 mph at Outagamie County Regional Airport.

A line of severe thunderstorms, known as a quasi-linear convective system (QLCS), produced six tornadoes and widespread damaging winds across east-central Wisconsin during the late night hours of August 6-7. The storms formed ahead of a cold front that also produced severe weather in Minnesota and western Wisconsin.||The tornadoes occurred within about 50 minutes--between 12:22 am and 1:10 am CDT. Hundreds of homes, businesses and farm buildings were damaged. Two injuries occurred at a campground in Waupaca County. Thousands of trees and power lines were also downed, leaving tens of thousands of people without power. The strongest tornado of the event reached EF2 intensity (winds estimated at 115 to 120 mph). This tornado caused significant damage to a church in New London. ||The six tornadoes that occurred on August 7 were the most nighttime tornadoes in a single event in northeast Wisconsin since accurate tornado records began (1950).

Very moist and unstable air interacted with an approaching cold front and produced severe thunderstorms. Some of the storms had wind gusts to 68 mph that downed trees and power lines, golf ball size hail, and heavy rain. Lightning from the storms struck a house in Brown County, causing it to fill with smoke. The storms also knocked out power to about 4,500 customers in Manitowoc County and dropped 2 to 3 inches of rain in parts of east-central Wisconsin.

The combination of a cold front, unstable air and an upper level disturbance produced severe thunderstorms that caused extensive damage across the Fox Valley. A small cluster of intense thunderstorms produced wind gusts in excess of 70 mph, causing widespread damage across central and east central Wisconsin. Thousands of trees and power lines were blown down by the thunderstorm cluster. Numerous buildings were damaged by fallen trees and high winds. Power was knocked out to 60,000 people at the height of the storm. ||Some of the highest measured thunderstorm wind gusts included 81 mph at Sherwood (Calumet Co.), 78 mph at Wrightstown (Brown Co.), 74 mph at Oshkosh (Winnebago Co.), 72 mph at Appleton (Outagamie Co.), and 65 mph at Point Beach State Forest (Manitowoc Co.).||One of the hardest hit areas during the storm was Appleton (Outagamie Co.). Widespread 70 to 75 mph wind gusts were experienced in the city, with isolated winds estimated at around 95 mph.

A weak upper level disturbance interacted with a very unstable air mass to create scattered severe thunderstorms across central and east-central Wisconsin. Wind gusts over 65 mph occurred with the strongest storms, knocking down numerous trees, power lines and two large power poles.

A strong winter storm produced heavy snow and blizzard conditions across parts of Wisconsin and Minnesota on December 11-12, 2010. A widespread snowfall of 8 to 14 inches along with frequent wind gusts over 40 mph affected much of northeast and central Wisconsin. Thundersnow was even reported at several locations in east-central Wisconsin at the height of the storm.||The snow developed as low pressure moved from Wyoming to southern Lake Michigan. Strong winds, in response to the pressure difference between Arctic high pressure over southern Canada and the low pressure system, created severe blowing snow and blizzard conditions across Green Bay, the Fox Valley and the lake shore counties. The strong winds blew down trees and limbs, resulting in power outages to thousands of homes. Fire departments in Two Rivers and Manitowoc opened their buildings as warming stations until power was restored. A large stretch of U.S. Highway 10 in Manitowoc County had to be closed for 9 hours due to white-out conditions. Stranded vehicles kept plow operators from effectively clearing some roads. Winds gusted well over 60 mph in northern Door County.||At least one death was attributed to the storm in the area. A male died of caridac arrest due to hypothermia near Marshfield early on December 12, after leaving his stranded truck to get help.||Some of the highest snowfall totals from the storm included 18.0 inches at Marshfield (Wood Co.), 16.2 inches at Plover (Portage Co.), 15.5 inches near Forestville (Door Co.), 14.7 inches 8 miles west of Merrill (Lincoln Co.), 14.6 inches at King (Waupaca Co.), 14.4 inches near Dancy (Marathon Co.), 13.5 inches at Lac Vieux Desert (Vilas CO.) and Pulcifer (Shawano Co.), 13.1 inches at Denmark (Brown Co.) and 12.5 inches at New Holstein (Calumet Co.). The 13.5 inches of snow measured in Wausau makes this storm the biggest December snowstorm ever in that city.||The highest winds with the storm were in Door County where peak gusts included 70 mph in Sister Bay, 68 mph on Washington Island, 66 mph at Northport Pier, 57 mph on Chambers Island and 50 mph in Sturgeon Bay. The high winds tore siding and part of a roof from a building in Fish Creek.||Significant peak wind gusts across the rest of the area included 53 mph in Green Bay, 50 mph at Manitowoc (Manitowoc Co.) and Oshkosh (Winnebago Co.), 48 mph in Appleton (Outagamie Co.), 46 mph in Antigo (Langlade Co.) and 45 mph in Algoma (Kewaunee Co.).

An area of low pressure moved into the Midwest on October 25th, rapidly intensified as it moved northward through Minnesota on October 26th, and tracked northeast through Lake Superior into Southeast Ontario on October 27th. As the storm reached peak intensity during the late afternoon on the 26th over Minnesota, the lowest barometric pressure readings ever recorded in the central United States occurred (subject to verification). A reading of 28.21 (955.2 mb) was recorded at Bigfork MN, a pressure that is found in Category 3 hurricanes! ||This intense storm produced wind gusts over 60 mph across parts of Northeast Wisconsin. Highest gusts included 79 mph in Sherwood at a well-exposed location on the northeast shore of Lake Winnebago (Calumet County), 68 mph in Algoma (Kewaunee County), 61 mph in Wausau (Marathon County) and 60 mph in Rhinelander (Oneida County). The high winds caused widespread power outages across mainly northern Wisconsin, with as many as 60,000 customers without power at the height of the storm. Trees were knocked down in scattered locations in the region, some falling on homes and cars. The strong and persistent southwest winds pushed the water out of the Fox River and lower part of the bay of Green Bay, with water levels falling some three feet from normal. Over the course of the next two days, the water sloshed back and forth with water levels rising and falling in the lower bay and Fox River between one and two feet as a seiche set up. Water levels returned to normal on the afternoon of the 28th as the winds shifted to the west, then northwest.||Damage amounts are estimated. The total damage could be considerably higher since any damage that might have occurred to vacation cottages won't be discovered until spring.

Numerous thunderstorms formed along a cold front that moved across the western Great Lakes. Storms that moved through northeast Minnesota and northwest Wisconsin during the night July 13 intensified during the day on July 14 as they moved across northeast Wisconsin. The storms produced wind gusts as high as 95 mph, funnel clouds, a weak tornado, and very heavy rainfall. The thunderstorms left more than 22,000 homes without power for at least part of the event.

Lightning from thunderstorms that moved across east-central Wisconsin caused a fire near Oshkosh (Winnebago Co.) and knocked out power on the east side of Green Bay (Brown Co.).

One of the biggest winter storms in years pounded much of Wisconsin, including the northeast part of the state. Snow developed as low pressure rapidly deepened as it moved across Illinois into Lake Michigan. Strong winds in response to the deepening low created blowing snow and near blizzard conditions very early in the morning on the 9th across parts of northeast Wisconsin. Winds gusted to over 50 mph in Door County, and to 48 mph at the NWS Green Bay office. During the height of the storm, lightning and thunder were reported in the Green Bay area and in central Wisconsin.||The extremely wet and heavy snow combined with high winds to cause widespread tree damage and numerous power outages in northern Door County, mainly in the Baileys Harbor area and on Washington Island. Utility company reports indicated that about 12,000 customers, mostly in Door, Kewaunee and Marinette counties, lost power during the storm.||Widespread snowfalls of 8 to 16 inches were reported across much of northeast, east-central and central Wisconsin. Some of the highest totals included 16.5 inches in Allouez and Ledgeview (Brown Co.), 16.2 inches on Green Bay's east side (Brown Co.), 15.6 inches in Scandinavia (Waupaca Co.) and 15.5 inches at St. Nazianz (Manitowoc Co.). Officially, 14.7 inches fell in at the National Weather Service in Green Bay.||The 14.7 inches in Green Bay placed the storm in the top six biggest snowstorms in Green Bay weather history (observations since 1886), and was the biggest December snowstorm ever.

Several supercell thunderstorms developed ahead of a slow moving cold front. The storms produced damaging winds from wet microbursts and quite a bit of large hail.||High winds and hail from the storms combined to topple trees, damage crops and knock down power lines from Ogdensburg (Waupaca Co.) to Weyauwega (Waupaca Co.). Hail was piled up 9 inches deep in the ditches along Butternut Ridge Road between the cities of Waupaca and Weyauwega after the storm passed.

A cold front that moved from northwest to southeast across Wisconsin triggered thunderstorms in unstable air ahead of it. The southeast-moving storms produced copious amounts of large hail, up to golf ball size, high winds that downed trees and power lines, and a funnel cloud.

An intense low pressure system that moved from the Plains to southern Wisconsin produced heavy snow and strong winds across northeast Wisconsin. Thunder accompanied the snow showers early on the morning of the 25th in east-central Wisconsin. The heavy snow and strong winds led to power outages for parts of Seymour (Outagamie Co.) and for 100 customers on the east side of Green Bay (Brown Co.).|The highest snowfall totals from the storm included 20.0 inches at King (Waupaca Co.), 18.9 inches at Carlsville (Door Co.), 18.5 inches at Amherst and 17.9 inches at Almond (Portage Co.), 17.0 inches at Waupaca (Waupaca Co.), 16.6 inches at Wautoma (Waushara Co.) and 16.0 inches at Ephraim (Door Co.) and Kewaunee (Kewaunee Co.).

A thunderstorm complex that formed in northwest Wisconsin moved southeast across the area during the early morning hours producing large hail and causing extensive wind damage. A wind gust of 63 mph was reported by the Appleton (Outagamie co.) AWOS, the Green Bay (Brown co.) ASOS recorded a gust of 62 mph and a trained spotter in Waupaca (Waupaca co.) measured a 59 mph wind gust. The high winds damaged a gas station canopy near downtown Green Bay, flipped an airplane at the Appleton airport and downed numerous trees and power lines across the area. Power was knocked out to about 6,000 customers in the Fox Valley and between 4,000 and 5,000 customers in the Green Bay area.Heavy rainfall in Manitowoc (Manitowoc co.) resulted in localized street flooding and caused some manhole covers to pop off.A lightning strike in Wausau (Marathon co.) caused a natural gas line to rupture and leak underground. The gas then ignited and burned much of the siding along an exterior wall of a house. A cabin in Minocqua (Oneida co.) was struck by lightning. The electrical and plumbing heated up and started the floor on fire.

Scattered severe thunderstorms developed as a slow moving cold front entered northern Wisconsin from the northwest. Golf ball size hail fell in Bonduel (Shawano co.), half dollar size hail fell 3 miles west of Ashwaubenon (Brown co.) and there were several reports of penny to quarter size hail across the area.High winds snapped and uprooted trees in Spencer (Marathon co.) and downed trees and power lines across Shawano county and around Keshena (Menominee co.). A large billboard was blown from its mountings south of Antigo (Langlade co.) along Highway 45.An apparent wet microburst occurred in Brown county when extremely heavy rain fell as a 50 knot south wind was measured at the National Weather Service in Green Bay. Two airplanes at the airport sustained damage. Trees and tree limbs were knocked down in the Green Bay, De Pere and Hobart areas of Brown county.Around 2,000 customers in parts of Shawano and Menominee counties and about 1,400 customers in Brown county lost electrical service due to the storms.A 24 year old man died in Antigo when lightning struck a tree near where he was standing and the current traveled into his body.

An unusually strong low pressure system, for the month of May, moved north across Michigan and produced heavy rain and high winds in northeast and north central Wisconsin. The high winds downed power lines and knocked down and uprooted trees.Door county was hardest hit. Approximately 14,000 people lost power, at least temporarily, when trees knocked out the transmission line leading into northern Door county. There were power outages in 184 locations throughout the county, with most of them concentrated in northern Door county. Power was still out to 1,100 customers as of 5:30 PM the next day. The high winds also severely damaged a boat launch at Peninsula State Park.Strong winds downed trees and power lines in Vilas county, Oneida county, Brown county and southern Marinette county. One man died from injuries suffered when he was struck by a tree while trying to fix power lines in the town of Wausaukee (Marinette co.). Around 3,000 customers in the Wausaukee area and 1,000 in the Marinette area (Marinette co.) lost power during the storm. About 2,700 customers lost power in the Eagle River (Vilas co.), Minocqua (Oneida co.) and Rhinelander (Oneida co.) areas. In Brown county around 800 customers lost power and one house was damaged when a tree fell on it. The heavy rainfall that accompanied the high winds resulted in some lowland flooding in the town of Ledgeview (Brown co.).

Strong south to southwest winds developed as a deep low pressure system moved across northwest Wisconsin and Lake Superior. The winds caused scattered power outages, broke tree branches and tore shingles from roofs. In Appleton (Outagamie co.), a 6 foot section of fence was blown over which included two 4 inch by 4 inch posts that were snapped at ground level. A large tree was also blown down at a nearby residence damaging a house. The highest wind speeds were: 66 mph in Hortonville (Outagamie co.), 64 mph in Bellevue (Brown co.), 63 mph in Kimberly (Outagamie co.) and 61 mph in Algoma (Kewaunee co.).

Thunderstorms developed as a cold front interacted with a moist and very unstable air mass over Wisconsin. Many of the storms became severe, with gusts in excess of 60 mph, as they moved across east central Wisconsin. Downed trees and power lines were widespread. At least 50,000 people on the north side of Oshkosh (Winnebago co.) were without electricity for at least part of the evening.

Winds estimated at 80 mph downed numerous trees in western Marathon county and knocked out electrical service to about 2,700 customers around Athens and Stratford. Two supercell storms that moved through southern Forest county caused significant wind damage, dropped large hail and produced a funnel cloud. Three square miles of trees in the Nicolet National Forest were heavily damaged as winds estimated at 90 mph hit the south part of Birch Lake. High winds tore the roof from a metal building in Laona and a funnel cloud was spotted 3 miles east of Crandon. Two inch diameter hail fell at Crandon and baseball size hail fell at Laona.

A powerful storm system in the upper levels of the atmosphere combined with an approaching surface system to produce a band of moderate snow across central and northeast Wisconsin. Snowfall in Door county from this storm was enhanced by Lake Michigan. Some of the higher snowfall totals included 11.4 inches at Baileys Harbor (Door co.), 10.0 inches at Oconto (Oconto co.), 9.5 inches at North Bay (Door co.), 8.4 inches 4 miles northeast of Kaukauna (Outagamie co.) and 8.0 inches at Green Bay (Brown co.) and Marinette (Marinette co.).

Brisk northeast flow around a high pressure system in southern Canada brought unseasonably cold air into northern Wisconsin. At the same time, low pressure moved east along a nearly stationary frontal boundary that was over northern Illinois. A mixture of freezing rain and sleet developed north of the front resulting in the formation of ice on trees, power lines and roads.Roads in central and northern Wisconsin became ice-covered and hazardous and numerous traffic accidents were reported. Four fatal accidents occurred on the slippery roads in central and east-central Wisconsin and 78 accidents were reported in Brown county alone.Downed electrical lines caused power outages to about 21,000 customers in east-central Wisconsin, including about 3,000 in the Two Rivers (Manitowoc co.) area, 3,000 near Kewaunee (Kewaunee co.) and about 15,000 in the Appleton (Outagamie co.) area.

Thunderstorms moved through Wisconsin in very warm and unstable air ahead of a cold front. Severe thunderstorm winds and tornadoes downed trees and power lines and damaged buildings across a large swath of central, north central and east central Wisconsin. Thousands of trees and power lines were downed by high winds from the storms. An 11 year old Boy Scout was killed and another was seriously injured when trees landed on their tent at Camp Napowan (Waushara co.).High winds pushed a house off its foundation and blew a boat and trailer into a neighbor's yard near Merrill (Lincoln co.). Some downed trees damaged or destroyed buildings or vehicles when they fell. A church steeple was toppled by high winds and a tree landed on an SUV, boat and trailer in Neenah (Winnebago co.)

A powerful cold front moved through central and eastern Wisconsin during the late afternoon and evening. Gusty winds accompanied showers and thunderstorms ahead of the front and continued as cold air moved into the region after the frontal passage. The strong winds behind the front downed trees and power lines across northeast and north-central Wisconsin, knocking out power to about 4,000 customers. The strong winds caused large pieces of metal to become detached from a skywalk under construction in Antigo (Langlade co.). One vehicle was damaged by the falling pieces of metal.The strongest gusts recorded were at 55 mph at Rhinelander (Oneida co.) and 3 miles southeast of Hortonville (Outagamie co.), 48 mph at Sturgeon Bay (Door co.) and Eagle River (Vilas co.) and 47 mph at Antigo (Langlade co.).

Sailboats that were on their trailers were tossed by the strong winds and a barn was leveled.

Thunderstorms developed across northern Wisconsin as a weak cold front and an upper level disturbance moved across the state. Some of the thunderstorms downed trees and power lines and produced large hail.

A strong cold front swept into southwest Wisconsin during the mid morning hours. A narrow line of severe thunderstorms developed immediately ahead of the cold front. The storms caused strong winds aloft to reach the surface, resulting in damage to trees and power lines. At least 8,000 customers lost electrical power due to the storms. Thunderstorm winds ripped the tin roof from a barn in Marinette county and downed a shed near Freedom (Outagamie co.). More than 100 trees were downed by thunderstorm winds near Alice Lake (Lincoln co.). Two cottages were destroyed and six others were damaged when trees landed on them. One person sustained a minor injury when a mobile home was flipped on its side by thunderstorm winds 5 miles east northeast of Tomahawk (Lincoln co.).A waterspout developed over the southern part of Green Bay and moved north along the shoreline before it dissipated.

A strong low pressure system dragged an occluded front through Wisconsin as the low moved northeast across Minnesota. High winds behind the front downed numerous trees, tree limbs and power poles across central, east central and northeast Wisconsin. The wind removed part of the roof of a building in Rosholt (Portage co.) and knocked over a billboard in Outagamie county. The wind and accompanying warm and dry air contributed to the development of grass fires in the Coloma and Red Granite (Waushara co.) areas.High winds drove slabs of ice from Lake Winnebago onto the shore. A dead end street in Oshkosh (Winnebago co.) at Lake Winnebago was piled with a 20-foot to 30-foot high mountain of ice that threatened at least one home.

Strong winds developed across central and east central Wisconsin on the back side of an intense winter storm system that was moving away from the state. The wind caused power outages for around 800 customers in the Brussels (Door co.) area and 200 customers in the Oshkosh (Winnebago co.) area. The strongest wind gusts recorded were, 47 mph at Manitowoc (Manitowoc co.) and Stevens Point (Portage co.), 46 mph at Appleton (Outagamie co.), 44 mph at Green Bay (Brown co.), 43 mph at Sturgeon Bay (Door co.) and 42 mph at Oshkosh (Winnebago co.).

Sunny skies and lingering low level moisture allowed the atmosphere to destabilize. Weak surface troughs combined with upper support to initiate storms. The storms downed trees and power lines and dropped large hail as they moved through northeast Wisconsin. Two people were injured by quarter size hail at a golf course in Alaska (Kewaunee co.). A tornado briefly touched down northeast of Forestville (Door co.) with one of the storms.

A nearly stationary front across Wisconsin combined with upper air support and abundant moisture to produce a prolonged period of thunderstorms. A few of the storms contained high winds and hail but flooding from heavy rainfall caused the majority of the problems.The heaviest rainfall occurred in an area that extended from southern Vilas county southeast into Manitowoc county. Rainfall totals in this area ranged from 2 to 4 inches for the 24 hour period ending at 6:00 AM CST on the morning of the 8th. Flooding of roads and/or basements was reported in the area from Pelican Lake to Rhinelander (Oneida co.), around Antigo and Deerbrook (Langlade co.), Crandon (Forest co.), Keshena (Menominee co.), Oconto Falls (Oconto co.), Green Bay and De Pere (Brown co.) and Manitowoc (Manitowoc co.). Small streams and creeks overflowed their banks and rural areas suffered some crop damage.Green Bay (Brown co.) received 4.12 inches of rain on July 8th and 4.65 inches of rain in a 24 hour period spanning July 7th and 8th. These totals set a new rainfall records from July 8th and for the month of July respectively. The previous record 24 hour total was 4.39 inches set on July 23, 1912.At least 25,000 customers lost electrical power as a result of the storms. Strong winds downed trees in Wittenberg (Shawano co.), Tigerton (Shawano co.) and Marion (Waupaca co.).

Strong winds behind a cold front caused broken tree limbs and branches to fall onto power lines. Between 2,000 and 3,000 customers lost electrical power in parts of central and east central Wisconsin. The strong winds downed five small trees at Green Bay Botanical Gardens. The strongest wind gust was 46 mph at Appleton (Outagamie co.). Peak gusts were in the 35 mph to 45 mph range across the rest of the area.

Strong winds blew as sinking air behind a cold front brought stronger winds from higher levels of the atmosphere down to the surface. Sustained winds were mainly 30 to 40 mph with gusts in the 40 to 50 mph range. Scattered trees and power lines were downed by the winds in Oneida county.
