What happened

The episode as NWS MKX wrote it up.

Widespread gradient high winds raked south-central and southeast Wisconsin for 5 hours. Maximum winds gusts were in the 50 to 57 knot range (58 to 66 mph). There were numerous reports of felled trees and broken tree branches, roof shingles and rain gutters torn from homes, and chain-link fence damage. The strongest sustained winds and gusts occurred mostly between 1400 and 1600CST. The 57 knot (66 mph ) maximum gust was observed at the Milwaukee Betty Brinn Museum. A gust of 55 knots (63 mph) was observed by a severe weather spotter near Dousman (Waukesha). About 49,000 customers lost electricity at one time or another.A tractor-trailer driver on Interstate 90 near Janesville (Rock Co.) was injured when his truck was blown over. The wind gusts capsized a boat east of the Hoan Bridge in the nearshore waters of Lake Michigan, but the occupants were rescued. In the city of Salem (Kenosha Co.), the high winds pushed a dumpster into a parked law enforcement vehicle which resulted in major damage. In the city of Kenosha (Kenosha Co.), the high winds toppled a 50-foot tall antenna onto a home, resulting in roof and rain gutter damage. Grass fires were noted in the counties of Milwaukee, Washington, Columbia, Walworth, Racine, Waukesha, Green, and Rock. At least 400 acres burned in Walworth County.Synoptically, deep low pressure moved northeast through central Minnesota to northern Wisconsin. Southwest winds at 850 mb (about 5000 feet AGL) were in the 60 to 65 knot range over eastern Iowa into southern Wisconsin. At 500mb (about 18,000 feet AGL) they were 80 to 90 knots.
