 Brief Description: A tornado developed two miles Southwest of Washington Iowa and produced a 30 mile long continuous path of damage and debris as it moved to the Northeast at nearly 30 mph. The tornado weakened and lifted before reaching I-80 near West Branch Iowa shortly before 6pm. The tornado continued Northeast across Cedar County Iowa producing another 15 miles of isolated damage...not continuous. The storm producing this tornado continued Northeast producing a brief touchdown one mile west of Oxford Mills Iowa near the intersection of county roads E53 and X64. Another brief touchdown occurred south of Dubuque near Zwingle Iowa before the storm moved into Wisconsin. In Washington Iowa extensive damage was reported to businesses, a church, numerous homes, an apartment complex housing elderly residents and a livestock sale barn. Fourteen single family homes were destroyed, another fourteen received major damage and forty five reported minor damage. Three multi-family housing units were destroyed and two received major damage. Twenty six detached units (sheds and garages) were destroyed or sustained major damage.

 Brief Description: Rated very high F2 with winds estimated at 155 mph. Tornado developed at the intersection of highways 1 & 218 on the southwest side of Iowa City at 1929 CST and tracked northeast through the city before lifting just northeast of the intersection of 1st Avenue & Hickory Trail at 1937 CST. This path took it through the southeast corner of the University of Iowa campus. This was the first tornado to hit near the campus in 35 years and the University was closed on Friday April 14th for safety reasons. The KIOW ASOS at the airport on the southwest side of the city recorded a peak wind gust of 49 knots (57 mph) at 1931 CST. This gust was likely the result of the rear flank downdraft as the tornado neared the intersection of U.S. 6 and highway 1 northeast of the airport. Hard times for the location of the tornado are 1930 CST at the Wal-Mart. At 1932-1933 CST power was lost at the Johnson County Sheriff Office with telephone lines, LAN, and automated systems going down as the tornado passed over the building. While the tornado was passing over the sheriff's office, someone flipped the outdoor warning sirens from automatic to manual override and activated the sirens one final time. Damage totals are still being evaluated and the $12 million amount will likely be closer to $15 million or possibly higher. Known damage amounts include; Iowa City and Johnson County $4 million with an additional $755,000 of uninsured loses (traffic lights, signs, street lights), University of Iowa $6 million with the motor pool headquarters a total loss and 31 vehicles damaged, and $1.3 million in damage to residences/businesses. Three automobile dealerships were damaged; one dealership had 200 vehicles damaged, a second had 60-70 vehicles damaged, and a third had nearly every vehicle sustaining some type of damage. A total of 1,016 residential and 35 commercial buildings were damaged with some destroyed. Some well known landmark buildings known to citizens, college students, and alumni were lost or heavily damaged. These included the Dairy Queen (lost) and St. Patrick's Church (heavily damaged). Several historic buildings were damaged downtown and it is unknown whether or not they can or will be saved. The tornado damaged the Alpha Chi Omega sorority house and damaged many student apartments located just off the campus on Iowa, Dodge, and Governor streets. Given the strength and width of the tornado it is amazing that only 30 injuries (many minor) occurred. Many U of I students were unaware of what was happening or dashed to a nearby parking garage for safety with the tornado approaching a few blocks behind them. Several foreign exchange students, many of whom had never seen, experienced, or heard of a tornado, were in awe and disbelief over the magnitude of the event. At St. Patrick's Church, the Maundy Thursday evening service had just ended. Upon being told of an approaching tornado by Decon Jerome Miller, the Reverend Rudolph Juarez ushered 50 to 75 parishioners (many elderly) to the safety of the rectory basement next door. This action saved the lives of everyone as the tornado tore off the roof off the church and collapsed the top portion of the brick facade and the steeple into the main congregation area.

 Brief Description: A vary dynamic weather pattern was in place across Iowa. The air mass was very unstable with total total indices of 61, K indices over 30, and helicity values over 600 m2-s-2. Soundings at 1200 UTC already indicated lifted indices of -7 C. Moisture pooling was taking place ahead of a windshift line which extended north to south across central Nebraska at sunrise. Dew point values rose to around 80 F. over most of Iowa in the morning. A strong cap was in place with 700 mb temps nearing +15 C. This held convection to a minimum. Thunderstorms had formed the previous night across South Dakota and advanced into southern Minnesota. They slid southeast and moved into north central Iowa during the late morning hours. Golf ball-size hail pelted Worth County northeast of Northwood. A short time later a second cell dropped dime-size hail on the area. The storms advanced southeast producing hail and gusty winds. Most of the activity was just below severe limits. When the storms reached Clayton County, dime size hail was reported in Luana. Meanwhile, in Garnavillo high winds were a problem. Several trees and numerous power lines were downed in the city as the gust front passed. In addition to the first cluster of storms that slid southeast, a line of thunderstorms formed quickly on its heels ahead of the trough/windshift line. These storms quickly became severe in the unstable air mass and joined with the aforementioned cluster of storms. Once the storms became severe, they produced considerable damage. Hail up to baseball-size, very high winds, and tornadoes resulted. There were several small tornadoes and one gustnado produced by the line. Of the more significant tornadoes, one tracked across Buchanan and Delaware Counties and caused damage to many out buildings. The tornado struck a few farmsteads directly and damaged many others. Considerable damage was reported along its path. One house was destroyed, two others sustained about $25 thousand damage each, five others sustained about $20 thousand damage, and a mobile home was destroyed worth $10 thousand. A grain elevator was struck near Lamont with damage placed to it at $500 thousand. A total of 19 farmsteads sustained damage in the county. Crop damage by the tornado was also severe with damage described as if "someone went through the fields with a Weedeater". Two head of cattle were killed near Lamont when the barn they were in collapsed. Another tornado that was on the ground for a significant length of time tracked across Clinton County. Other significant tornadoes struck Scott and Muscatine Counties. Straight line winds caused considerable damage in Delaware County. There were numerous reports of livestock killed or injured by fallen barns. Three hogs were crushed on a farm near Hopkinton for example. Damage from straight line winds alone in the county were placed near two and one half million dollars. Damage was very extensive around the Hopkinton area with many farmsteads affected and some nearly wiped out. Estimates from the entire Quad Cities metro area range to around $5 million. There was also considerable damage in Jones County from high winds. Wind gusts of at least 85 MPH destroyed 24 mobile homes and three permanent homes in Monticello. There was also damage reported to several other houses and businesses in the area. Other wind damage in the Monticello area included three silos destroyed, two large barns downed, two machine sheds, a corn crib, and six open sheds. Three head of cattle were killed as one of the barns collapsed on them. In another incident, a horse stable was blown down by the winds. One horse was killed as the stable toppled down on it. Also, in Monticello, a man was injured as high winds downed a tree on top of his car. Reports indicated the total property damage in the Monticello area were at least $1.8 million and were expected to top the $2 million mark. Estimates of crop damage due to the wind totaled close to $1 million across Jones County. Cedar County, winds of 90 to 95 MPH in close proximity to a tornado in the area destroyed one house and several buildings north of Atalissa. The tornado itself hit one farmstead north of the Atalissa area. Reports indicated food was sucked out of the refrigerator and boards were taken out of loaded grain wagons. When the house was hit, a letter from the attic was picked up shortly before 1900CST. The letter was retrieved at 1940CST; 40 miles from its original location in the Quad Cities. There were numerous reports of small rope tornadoes around the Lowden area. Two are included in this report. The tornado northwest of town touched down briefly in an open field. There were actually three separate touchdowns from one parent cloud within a period of several minutes. A local network of spotters in the county observed 24 funnel clouds. In addition to the tornadoes and winds, hail was a major problem. There were numerous reports of one to two-inch diameter hail. There were also several reports of baseball-size hail. In Clinton County, Grand Mound and DeWitt were pelted with baseball-size hail causing considerable damage. The airport at Clinton sustained damage by baseball-size hail as well. In Calamus, baseball-size hail fell on the city. The hail in combination with the wind damaged cars, knocking out windows. Windows were also knocked out of several buildings in the city. Hail also caused considerable crop damage in east central Iowa. Five thousand acres of corn and soybeans were totally destroyed, 10,000 acres slightly damaged, 50 hogs killed, and 10 head of cattle killed in a three county area. The Governor declared Buchanan, Delaware, and Jones Counties disaster areas. Damage and losses totaled into the millions. Earlier in the afternoon, lightning struck a barn in Winneshiek County near Castalia. The barn was a total loss as it burned to the ground.

 Brief Description: Tornado reported by emergency manager Event Summary for 09/06/01: A strong short wave trough in the upper level atmosphere, moved northeast through Iowa and Wisconsin during the afternoon and evening hours. This wave of energy helped thunderstorms, which were moving along a warm front in northeast Iowa, become strong. Despite the lack of convective available potential energy, ample moisture and wind shear along the front allowed thunderstorms within this area of rain to rotate and produce a few short lived tornadoes. One storm in Buchanan County Iowa, produced two tornadoes as it quickly moved northeast along the warm front. Here is a summary of the tornadoes which struck northeastern Buchanan County Iowa. At 605 pm CDT, an F0 tornado touched down 5 miles southwest of Aurora, Iowa, producing damage to the Ralph Kramer farm site. Several out buildings were damaged or destroyed. One empty grain bin was moved off of its foundation. The home only had minor damage, with some siding blown off. The tornado continued moving northeast, producing crop and tree damage as it crossed 142 street. At 625 pm, the tornado struck the Lonnie McAllister farm site, again damaging or destroying farm out buildings. This is also where the most significant crop damage was observed. The tornado then lifted, leaving a trail of some tin and other debris, as the storm moved northeast. This tornado was on the ground for 3.5 miles and was 40 yards wide at its widest point. At 630 pm CDT, an F2 tornado touched down 0.25 miles southwest of Aurora and quickly moved across Aurora, producing damage to the roof of the American Legion building in Aurora. The tornado then struck the Ken Mosher home just east of Aurora. The tornado totally ripped off the roof and two car garage of this newer frame dwelling. The tornado then lifted 0.75 miles northeast of Aurora, and no other tornadoes from this storm touched down again until it had moved about a mile north into Fayette County, Iowa. This tornado was on the ground for 1 mile, and was 50 yards wide.

EPISODE NARRATIVE: Heavy rain-producing showers and thunderstorms moved across much of eastern Iowa and northwest and west central Illinois from the evening of May 25th to the early morning of May 26th. Some of the stronger storms also produced tornadoes, damaging winds, and large hail. Buchanan, Delaware, and Dubuque counties in Iowa were hardest hit with the heavy rains, where rainfall totals of 3 to 8 inches fell resulting in flash flooding.

 Brief Description: This tornado destroyed 26 farm buildings, 20 of them with major damage. Nine homes were hit, one destroyed, two with major damage and six with minor damage. Seven of the nine homes were farmhouses. Roxanne Paper, with baby boy Logan in arm, was downstairs when the tornado struck. She reported that it sounded like something big was tearing through the house. The Gary Meincke farm was hit very hard. He and his wife watched the tornado touch down south of their farm at around 1630 CDT. Shortly after that they ran with their children to the basement. Debris from the Leroy Feldhahn farm near Stockton was spread over nearby Interstate 80 causing a two mile long traffic jam. Governor Terry Branstad later proclaimed a Disaster Emergency for Scott County.
