 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.

 Brief Description: A supercell thunderstorm, after dropping a couple tornadoes in northeast Iowa, eventually moved northeast into Lafayette county, creating another tornado. This tornado touched down just southwest of Benton and hopped/skipped northeast for 20 miles. It caused moderate to severe damage to 40 different farms and their outbuildings, and homes. Numerous power lines were downed. Eleven people were injured: 2 children near Cuba city, 3 children southwest of Truman, and 6 adults in a vehicle on Highway 81 south of Benton.

 Brief Description: Six tornadoes affected southwest Wisconsin, which was part of an all-time one day record of 27 tornadoes hitting the state. The first tornado touched down briefly just west of Centerville (Trempealeau County). The only damage reported with this tornado was several trees knocked down just north of Highway 35 along County Road G. A second and stronger tornado occurred just north of County Highway KK, or just west of Esofea (Vernon County). There was tree, agricultural and structural damage. A moblie home, which was on cement blocks, was completely destroyed. The occupant of the mobile home was taken to a hospital with minor injuries. Another residence sustained minor damage, with windows blown out, outbuildings destroyed and a car turned 90 degrees. Power poles were snapped, corn was flattened and there was significant tree damage. The third and strongest tornado touched down just west of Liberty (Vernon County), then tracked along a continous path just north of Highway 56, to the northern most block of the town of Viola (Richland County). Three people were reported injured in Viola and almost every tree in the town was damaged or downed. Most homes in the village had at least minor damage, while a few sustained major damage, including roofs blown off. Many garages facing west or southwest were destroyed by the direct impact of the winds. Wind speeds associated with the tornado were estimated at 100 to 120 mph. The tornado path became more sporadic as it moved east of Viola across northern Richland County. The damage path extended from just north of County Highway MM and Highway 56 into Bloom City (Richland County), which apparently took a direct hit from the storm. The tornado continued on an east-southeast track, before lifting just west of Hub City (Richland County). A fourth tornado touched down along County Road N, or just east of the location where Interstate 90 and 94 split in eastern Monroe County. This tornado continued on a 10 mile track into Juneau County, ending just west of the Necedah Wildlife Refuge Headquarters. There was tree, agricultural and structural damage. A home, which was under construction, was completely destroyed. Three other homes sustained minor damage. Corn was flattened and there was significant tree damage as well. A fifth tornado touched down in the town of Muscoda (Grant County) causing minor damage to homes, but knocking down or shearing off numerous trees. This tornado crossed the Wisconsin River into the small community of Orion (Richland County). Several mobile homes were damaged, including several reportedly tossed into the air. Many trees were damaged there as well. The sixth and final tornado briefly touched down near the intersection of Highway 82 and 13 in Adams County. Mobile homes were damaged, along with nearby trees. Richland and Vernon County were declared federal disaster areas.
