Damaging Winds and a Couple of Brief Tornadoes Across Southern Wisconsin

A cluster of strong thunderstorms evolved into a line as they tracked across southern Wisconsin on Monday, August 10th, 2020. The storms produced damaging winds and a couple of brief tornadoes. The counties hardest hit were right along the WI/IL border: Lafayette, Green, Rock, Walworth, Racine, and Kenosha Counties. 

These strong thunderstorms evolved from several thunderstorms over southern Minnesota and northern Iowa early on Monday into a widespread, long-lived wind storm, or "Derecho".  For more information on Derechoes, check out the Storm Prediction Center Derecho Facts Page.
