Today

A cold front will approach southern Wisconsin this afternoon and bring a chance of severe weather. The Storm Prediction Center has placed all of southern Wisconsin in a slight risk for severe thunderstorms for this afternoon and evening. It looks like thunderstorms will develop in eastern Minnesota or Eastern Iowa during the morning to early afternoon and evolve into a broken line which will push east towards southern Wisconsin during the afternoon and evening. These storms may be widely scattered, so not everyone will see rain. However, any storms which do develop would have the potential to produce damaging winds, large hail, and possibly even a tornado. Be sure to stay weather aware today in case severe weather develops.
