The best chance for rain comes early tonight with showers and thunderstorms until about 2am. Overnight low temperatures in this humid air will be in the upper-sixties for most locations. High temperatures on Wednesday will still be in the low-sixties for Milwaukee with a good chance for scattered showers and thunderstorms. The rain should be gone by early evening on Wednesday night, and then slow clearing as cooler air rolls into southeast Wisconnsin. Skies will be sunny on Thursday as less humid air settles into the state and temperatures drop into the mid-seventies.
