Milwaukee Weather: Morning fog then mostly sunny

Published September 28, 2026 4:17 AM CDT

Forecast from FOX6 Chief Meteorologist Rob Haswell

After some patchy morning fog, Monday should turn into a pretty nice early-fall day with light winds, decreasing clouds and highs in the lower 70s. Tuesday stays mild and breezier, but the next round of rain continues to slow down and may not arrive until after midnight Tuesday night. Wednesday into Thursday is the messy part of the forecast, with a slow-moving front potentially stalling across Wisconsin and keeping periods of rain around longer than previously expected. There could be a few rumbles of thunder, but limited instability means severe storms are not expected. Cooler, quieter weather takes over Friday and Saturday.
