Milwaukee, Wis. – Steamy heat and scattered thunderstorms could disrupt Independence Day plans across Wisconsin, with temperatures climbing into the mid-90s and storms threatening through Sunday night.
According to the National Weather Service in Milwaukee, very warm and humid conditions are expected Thursday through the weekend, pushing heat index values into the upper 90s across southeastern, south-central, and east-central parts of the state. Isolated storms are possible each afternoon and evening starting Thursday, with the best chance of rainfall arriving Saturday into Sunday.
Cities like Milwaukee, Madison, and Waukesha could see brief downpours and gusty winds, especially during the peak of holiday travel. Independence Day itself will likely remain dry, though a few morning storms can’t be ruled out in central and southern counties. Localized heavy rainfall may linger into Sunday night, particularly along the I-94 corridor.
Drivers should plan for changing road conditions, especially during the afternoon hours when storms are most likely. Stay hydrated, limit outdoor activity during peak heat, and ensure backup power or cooling plans if celebrating outdoors.
Heat and storm risks remain elevated through Tuesday, and further alerts may be issued heading into the weekend.
