Milwaukee, Wisconsin – Heat and humidity are making a comeback across Wisconsin this week, with temperatures soaring to the upper 80s and low 90s by Tuesday afternoon. Many residents from Madison to Green Bay can expect a muggy day before storms move in.
According to the National Weather Service in Milwaukee/Sullivan, rain chances sharply increase late Wednesday, with the potential for strong or severe storms developing after 3 p.m. The highest risk zones stretch from Milwaukee and Waukesha west through Dane and Jefferson counties. Emergency managers advise residents to remain weather-aware and have multiple ways to receive alerts, especially during the afternoon commute.
Localized downpours could lead to minor flooding in urban areas, and frequent lightning may disrupt outdoor activities. Motorists should be prepared for rapidly changing road conditions and possible delays on I-94 and I-43. If you lose power during storms, have flashlights and fully charged devices ready.
Rain and storms are expected to clear out early Thursday, ushering in cooler, drier air with highs in the low 70s. More updates are likely as the severe threat window approaches.
