Milwaukee, WI – Showers and thunderstorms are expected to move across southeast Wisconsin tonight and continue into early Sunday morning, bringing periods of heavy rain and lightning that could impact overnight travel.
According to the National Weather Service in Milwaukee/Sullivan, storm activity is expected to begin after 7 p.m. Saturday, with waves of rain and embedded thunderstorms continuing through Sunday morning. Brief heavy downpours and cloud-to-ground lightning are the primary concerns overnight, with small hail also possible in isolated cells.
Rain chances remain elevated across much of the region—including Milwaukee, Kenosha, Racine, and Madison—through early Sunday, with some areas seeing peak probabilities between 60% and 80% during the overnight hours.
Forecasters say a second round of stronger storms could develop late Sunday afternoon, although there is still uncertainty regarding exact timing and storm intensity. If storms strengthen, they could bring more widespread impacts, including gusty winds and localized flooding.
Storm chances are expected to continue into Sunday night, especially across southeastern parts of the state, before gradually tapering off into Monday morning. Additional chances for severe weather may persist through midweek.
Drivers are urged to remain cautious during periods of heavy rain, which could reduce visibility and create ponding on roadways. Residents should also ensure they have multiple ways to receive weather alerts overnight in case warnings are issued.
