Winds of 50 knots began at 1758 CST according to DVN ASOS. At 1800 CST measured gusts of 58 knots (67 mph) were recorded and at 1801 CST, DVN ASOS measured a gust of 67 knots (77 mph). Before the ASOS could update for 1802 CST a power failure occurred at the ASOS site. NWS personnel at WFO DVN estimated winds of at least 80 knots (92 mph) lasting for 2 or 3 minutes (Review of archived data indicated the DVN 88D measured winds of 80+ knots about 3 miles east of the office at 200 AGL). During this time about one third of the outer roof of the NWS building was peeled off (the roof is designed to withstand 90 mph winds). Only the air conditioning units on the roof prevented the peeling from going the entire length of the building. With the outer roof gone, water fell into the operations area necessitating a shut down of all equipment and implementation of service backup by WFO Des Moines. The only damage sustained to equipment inside the building was the phone system, 2 monitors, and 2 computer mice. Downed power lines were noted in the 9000 block of Harrison Street from the office along with numerous trees down.

Trees and limbs toppled some power lines.

Street lights damaged at 53rd Street and Eastern Avenue. Also, power was knocked out to 5,000 homes and businesses. Peak wind gust of 56 mph measured in Davenport.

8 inch diameter limb knocked down on power lines on the west side of the city. Reported by the general public.

Trees and power lines down at 13th Street and Brown Street.

On Thursday, June 29, a powerful severe wind event moved over the region. This event was known as a derecho given its long duration from north of Kansas City to southern Indiana and its consistent strong intensity. Almost all of the damage in the area surveyed locally was due to straight-line winds, at times easily peaking between 100-120 mph in far western Illinois. Those who experienced the event conveyed how the strongest winds persisted for 10 to 15 minutes, and in some locations, it lasted as long as 20 minutes, which is atypical for derecho events.||There were some swaths of enhanced damage. These were largely due to intense wind surges in the local area. One of these in Clark county, Mo was determined to be a short-lived EF1 tornado.

The evening of February 18th, a powerful cold front quickly moved through eastern Iowa and northwest Illinois. A narrow band of intense snow squalls accompanied this front, bringing a near instantaneous onset of brief winter storm conditions. Roads went from dry to snow covered in a matter of minutes, temperatures fell from around 35 to 28 in minutes, and visibility fell from over 6 miles to under 1/4 mile as the snow squall arrived. Snow accumulation generally was a 1/2 inch to 1 inch, falling in around 1 hour. Once the snow squall ended, dry and windy conditions continued the rest of the night.

A weaker winter storm moved into the area and added more ice and snow to the snow pack received the other day. This system moved in from the south and brought along a strong pull of warm air aloft. This led to a lot more ice accumulation than was expected prior to the event. While the storm was supposed to lead to mostly snow for the northern half of our forecast area, those areas received mainly freezing rain and sleet through most of the afternoon. This led to widespread ice accumulations of 0.10-0.25. In the southwest part of our forecast area, more ice accumulation was noted, with many locations reporting around 0.25 or even more. Along with the accumulating ice, some downed tree limbs and power outages were a result.||Mid afternoon, the freezing rain began to switch to snow from a line around Iowa City, IA to Freeport, IL. A relatively strong band formed in this location and dropped around 4 of snow, especially in the Iowa City area. There were widespread reports of 2.3 inches of snow and sleet accumulation across eastern Iowa.

A rare wake low wind event moved across eastern Iowa and northwest Illinois late Tuesday night into Wednesday morning. Sustained winds over 40 mph, and gusts over 60 mph occurred from 11 pm Wednesday to 4 am Thursday. These strong winds caused downed trees, power outages, and some minor structural damage to buildings.

A powerful line of thunderstorms developed ahead of a cold front that moved across eastern Iowa during the late afternoon and evening hours of August 28th. The line of thunderstorms produced damaging winds mainly south of a line from Cedar Rapids to Clinton Iowa. This line of storms also produced a tornado that traveled across Scott and Clinton Counties. There were also swaths of more intense damaging winds in Clinton, Henry, Iowa, and Scott Counties. The heaviest rain fell south of Interstate 80, where 2 to 4 inch amounts were reported.

A cold front pushing into a very moist and unstable airmass triggered numerous severe thunderstorms on May 30, 2013. Deep layer shear was moderate to strong and freezing levels were in the 11-12k foot level, which was ideal for large hail. The storms produced damaging winds, large hail and several weak tornadoes. An EF1 tornado touched down in Andalusia, IL around 445 pm CDT and traveled due north. This weak tornado crossed the Mississippi River and moved through eastern sections of Buffalo, IA. Wind speeds were estimated to be 95 mph. Some large trees were snapped and uprooted along the path. Some of the fallen trees fell onto houses. In extreme northeast Missouri, wind gusts estimated to be 70 mph produced heavy tree damage throughout Scotland County. Several outbuildings were damaged and about 30 power poles were snapped. The tree damage was mainly located between Bible Grove and Memphis.

A large low pressure system moved into the region and continued to deepen as it moved across Minnesota, becoming one of the most intense storms on record in the |Midwest on October 26-27, 2010. Very high gradient winds raked much of the Midwest with wind gusts of 50 to 60 mph. Iowa City and Dubuque reported wind gusts to 60 mph. In Davenport, the strong winds brought down a utility pole and power lines.

A strong upper air disturbance moved from Kansas to central Illinois on January 20, 2010. This was combined with a weak surface wave moving along a stationary front that extended from southern Missouri to Kentucky. Temperatures above the surface were above freezing, but below freezing at the ground. The result was an ice storm over much of eastern Iowa, western Illinois and extreme northeast Missouri, with widespread ice accumulations of 1/4 to 1/2 inch. Isolated thunderstorms also roamed across locations south of Highway 34 in southeast Iowa and extreme northeast Missouri. The ice knocked down some 1 to 2 inch diameter tree branches and smaller limbs, as winds gusted to 35 mph. There were also scattered power outages that lasted for up to 2 days, but no major outages were reported. In some areas, numerous accidents and vehicles sliding off the roads were reported.

A strong cold front plowed eastward through eastern Iowa and northern Illinois during the late afternoon and evening hours of June 27 triggering a line of severe thunderstorms. Several areas not only received torrential downpours of rain...but also saw wind gusts in excess of 60 mph which caused numerous reports of tree damage and downed some utility poles and power lines. One of the stronger storms hit just southeast of Walnut Grove, IL destroying a barn and a grain bin. In addition, hail 1.25 inches in diameter fell just north of Burlington, IA. Prior to all the wild weather, hazy, hot, and humid conditions prevailed across the region, with high temperatures ranging from the upper 80s north to upper 90s south.

A bowing line of severe thunderstorms, known as a Derecho, raced across Iowa and Illinois during the early morning hours of July 21 producing|widespread wind damage in about a 60 mile wide swath just south of Interstate 80. Winds gusting over 70 miles an hour toppled trees, ripped siding and shingles off homes and businesses, and left much of the region without power.

Non-thunderstorm winds blew across parts of eastern Iowa, mainly between Highway 20 and Interstate 80, during the afternoon of April 10th. Damage to some out buildings, flag and power poles, and trees were reported.

Due to the careful note taking and damage description of the individual along with actually witnessing a funnel, this is classified as a rare tornado on the cold side of the front that was initiated by a downburst.Tornado began just north of I-80 4 miles west of Le Claire at 2042 CST. The tornado traveled east northeast crossing 257th Avenue just south of 205th Street and dissipated on 205th Street about 0.5 miles east of the intersection of 257th Avenue and 205th Street at 2045 CST.The corner of a wooden roof was torn off a cattle building and boards scattered (some nailed themselves into the wall of the corn crib next to it). The entire roof was lifted and then set back down. The south cinder block wall collapsed inward on the cattle building and the north walls bowed out to the northeast from the roof lifting off. A large shed door on the east side of the corn crib next to the cattle building was torn off and flung 50 yards to the northeast. The door hit a 100 year old tree trunk and knocked it out of the ground. A window was blown out on the east end of the corn crib next to the original cattle building. The window landed on the northwest corner of the property up and over on the opposite side of farmhouse some 975-980 yards distance.Part of the steel sheeting was peeled back on the southwest corner roof of a new machine shed located to the north of the cattle building. A skylight window was sucked out of another freestanding cattle barn located to the east of the original cattle building.A wooden dog house on the porch of the farmhouse was flipped onto its roof and a power pole was knocked out a couple of miles northeast of the farm.

An upper level disturbance initiated a small cluster of thunderstorms in east central Iowa in a moist to near tropical atmosphere. The cluster bowed out across Scott County Iowa and then moved rapidly into northwest Illinois. Sporatic to near continuous wind damage occurred across Whiteside County Iowa with trees and power lines downed. In Coleta, Illinois, a tree fell on a moving vehicle and injured the driver.An hour before the small bowing line of storms developed, another line of storms bowed out across Whiteside County Illinois and produced estimated and measured winds of 43-48 knots (50-55 mph).

A strong fall storm system moved across the Upper Midwest during the day. Between 0900 CST and 1500 CST the surface low deepened at about 1 mb per hour. The strongest winds across Eastern Iowa and Northern Illinois coincided with the surface geostrophic maximum winds and a tropospheric fold that reached down to about 450 Mb. During the high wind event, about 15,000 people were without power and at least 4 radio stations (WXLP, KBEA, KBOB, and KORB) were known to be off the air. In Bettendorf, Iowa, part of the wall at Bowe Manufacturing collapsed around 1500 CST. Fortunately the building was evacuated and police closed down U.S. 67 before the failure occurred. Many observing sites recorded peak wind gusts in the 52 to 56 mph range (45 to 49 knots) with sustained winds of 30 to 40 mph (26 to 35 knots). Maximum measured winds were 53 knots (61 mph) by KWQC TV in Davenport, Iowa and 54 knots (62 mph) in Pearl City, Illinois. At Lock and Dam 11 in Dubuque, Iowa, wind equipment there carried a sustained wind of 49 knots (56 mph) at 1630 CST for about 5 to 10 minutes. Given the magnitude of the event, known damage appeared to be minimal. This may be due to the fact that most trees had already shed their leaves for the coming winter.

Less than one week removed from record warmth, a late January winter storm brought the region it's first dose of significant winter precipitation. The storm system developed over Southern California and then lifted east northeast through the Mid Mississippi Valley Wednesday into early Thursday producing heavy snow and icy conditions. The precipitation initially fell in the form of sleet and freezing rain along and south of Highway 34. Significant ice accumulations of 1/4 to 1/2 inch were reported with scattered power outages. Downed trees were also reported. Eventually the ice changed to snow in Southeast Iowa where the highest accumulations occurred. Amounts generally ranged from 8 to 13 inches. Further north heavy snow fell as far north as Highway 30, where 6 to 10 inches was common. The heavy snow and ice caused many schools to close. Many activities were either cancelled or postponed. Also, the winter weather was responsible for cancellations of several flights at the Quad City International Airport. There were numerous accidents with 2 indirect fatalities. One hand injury was reported when a man put his hand in a snow auger to unclog the heavy, wet snow.

Event Summary for 8/02/01: (For additional details, see individual entries for the date.)A surface boundary was in place, extending from southern Wisconsin into southwest Iowa. A moist and very unstable atmosphere interacted with the boundary to produce a line of powerful thunderstorms that raced across eastern Iowa and western Illinois during the afternoon and early evening hours. The primary threat was severe straight-line winds. There was one isolated report of nickel-sized hail. Numerous funnel clouds developed along the leading edge of the line, but there were no touchdowns reported. A likely downburst produced extensive damage over a two-block area in Burlington. Two people were injured when thunderstorm winds blew their car off the road in rural Scott County.

A vigorous upper level disturbance, dropping through the Dakotas, triggered scattered strong to severe thunderstorms from near Sioux Falls, South Dakota through Northern Iowa to near Rochester, Minnesota during the late afternoon on the 13th. The storms propagated east southeast during the evening. A small scale bow echo moved into the Waterloo and Marshalltown areas late in the evening on the 13th and weakened, as a gust front, marking the leading edge of cooler and stable air, surged out ahead of the small scale bow echo, choking off the inflow and weakening the storms. Additional strong to severe thunderstorms reignited early on the morning of the 14th, near the intersection of the outflow and surface cold front from Waterloo to Dubuque. The convection blossomed into a Mesoscale Convective System or MCS and tracked through Eastern Iowa producing very heavy rain, large hail and damaging winds. Lightning and strong winds from the storms knocked out power to some 4,400 homes in the Quad Cities.

The earlier round of thunderstorms had weakened and shifted east of the area. New thunderstorm development occurred quickly by late morning west of Waterloo and Marshalltown. The storms developed along and east-west frontal zone. Sufficient destabilization had occurred allowing CAPES to exceed 3000 J/Kg over much of the area. Other severe storms erupted over Southeast Iowa, Northeast Missouri and West Central Illinois as a Mesoscale Convectively induced Vorticity Maxima, from earlier thunderstorms in the plains, tracked eastward. Several reports of 60 to 70 mph winds, large hail and funnel clouds were received. The heavy rain, falling on saturated ground, led to urban and small stream flooding in a few areas. Severe winds forced many residents in Preston in Jackson County to take shelter. Tree limbs were scattered about, small trees uprooted, the Little League trailer overturned, and windows were broken from two businesses. Power lines were also knocked down. Severe winds also produced substantial damage in Durant in Cedar County. Damage included downed tree limbs, and roofs torn off a business and garage north of Main Street. Winds estimated at near 70 mph also caused damage in Olin in Jones County. Trees and power lines were knocked down, and several small structures were toppled, including a chimney on a home. Damage to a roof, sun porch and decorative fence was also reported along Maple and Trilby Streets. The Olin Community Park was forced to close because of downed trees and other damage. Trees were also toppled over in portions of Jefferson, Des Moines and Louisa Counties.
