The Storm Prediction Center had issued a tornado watch for south-central Wisconsin. However, most of the severe weather occurred in the southeast corner. Earlier in the day there were scattered showers and isolated thunderstorms across northern Illinois that were well behaved and posed no severe threat. However, the atmosphere quickly destabilized across far southern Wisconsin in the early afternoon which helped fuel the storms, quickly prompting the National Weather Service (NWS) to issue severe thunderstorm warnings for Walworth and Waukesha Counties.

Tornado Touchdowns

The NWS has confirmed two tornadoes both rated an EF-1 in Fon du Lac and Green Lake Counties. Some damage did occur but it was relatively minor. A possible tornado may have also occurred in Waukesha County southwest of Nashotah. Channel TMJ4 helicopter aerial video discovered a scaring path on the ground on Mission Avenue and Hickory Lane. Storm Chasing Fever's very own James Cullinane, researched this suspected area and confirmed scaring on the ground in a field. The NWS didn't find enough evidence to verify if a tornado had occurred in this area.


As the evening progressed, additional severe thunderstorms dropped copious amounts of heavy rain across Waukesha and Milwaukee counties where flash flood warnings were issued. Many communities saw 2 - 3 inches of rain in a 24 hour period.
