There’s a cold front sweeping across the Wisconsin. Converging winds at the surface, modest levels of atmospheric energy and directional vertical wind shear–in other a shift in wind direction with height–has been sufficient to spin the air ascending into t-storms there. It prompted tornado development and some damaging thunderstorm winds gusts in the Badger State–including gusts of 73 mph at Cudahy, 60 mph in Hartford and 58 mph at Mitchell Field—all in Wisconsin.

A TORNADO WARNING was issued for sections of southeast Wisconsin (Kenosha county in particular)–and A SEVERE THUNDERSTORM WARNING was issued early Wed afternoon for sections of McHenry and Lake counties in Illinois.
