Milwaukee Weather: Sunny Thursday, rain returns Sunday

Published August 27, 2026 4:29 AM CDT

Forecast from FOX6 Chief Meteorologist Rob Haswell

Thursday and Friday give us a pleasant finish to the workweek, with plenty of dry weather and highs near 80 to the lower 80s. Some early morning fog is possible, especially in the Wisconsin River Valley and other low-lying areas. The pattern starts changing Saturday as warmer, more humid air pushes back into the region and shower and storm chances increase. The best chance of widespread storms appears to arrive later Saturday night, but a stalled front could keep additional rounds coming through Sunday and into early next week. With plenty of moisture available and repeated storms possible, heavy rainfall could eventually become a concern.
