A line of thunderstorms bowed out as it moved through south-central and southeast Wisconsin, resulting in locally, powerful, downburst, straight-line wind gusts that leveled large trees and power lines.  Pardeeville (Columbia Co.) had the worst downburst (estimated wind gusts to 70 knots, or 80 mph) with about 4 dozen homes damaged (siding and gutters).  Many vehicles in Pardeeville were damaged by tree limbs or debris.  Two barns and 2 homes were damaged in the Eldorado to Fond du Lac area (Fond du Lac Co.) thanks to powerful wind gusts to about 65 knots (75 mph).  In Madison (Dane Co.), a wind-toppled tree fell onto a home, trapping a man in his bed.  Crop damage was photographed southwest of Pell Lake (Walworth Co.) by an ultralight pilot.  In the Twin Lakes area (Kenosha Co.), large tree branches damaged a home and a vehicle.  Utility companies noted that about 8000 customers lost power during the storms, wtih 1500 alone in Columbia County.
