Milwaukee Weather: Sunny Tuesday, storms return Wednesday

Published June 23, 2026 5:02 AM CDT

Forecast from FOX6 Chief Meteorologist Rob Haswell

Southern Wisconsin gets one more quiet and comfortable day today before thunderstorms move in late tonight and continue through Wednesday. The greatest concern remains Wednesday afternoon and evening, when a few storms could become severe with damaging winds and hail as a cold front sweeps across the state. Rain chances taper off Wednesday night, with only isolated showers or storms lingering into Thursday. Friday looks largely dry before another round of unsettled weather arrives sometime during the second half of the weekend.
Looking ahead, a noticeable warming trend develops early next week, bringing the potential for the first widespread stretch of hot and humid weather we've seen in a while.
