Milwaukee Basks Like It’s May, Then Braces For Thunder And Slushy Snow

Milwaukee is getting a spring preview on Monday, March 9, 2026, with clear skies, unusually mild air, and morning readings around 50°F. Afternoon temperatures are expected to surge into the upper 60s, a big jump for early March.

Afternoon Warmth Could Tie Or Break Records

Forecast highs are near 68°F, putting the city within striking distance of a daily record. The March 9 record for Milwaukee is 67°F, set in 2016, and the National Weather Service says temperatures in the upper 60s are likely today.

The warm spell will not last long. A cold front is expected to sag south late this afternoon into the evening. Thunderstorms and heavier rain are likely Tuesday evening into Tuesday night, with a 70–90% chance of precipitation. By Wednesday morning, temperatures should tumble, turning rain into a wintry mix and then into light snow as colder air moves in. Localized slushy accumulations are possible north of I‑94, and gusts could reach up to 30 mph, according to the National Weather Service Milwaukee/Sullivan.

Commute And Boating Impacts

Late Tuesday thunderstorms could bring brief heavy downpours and lightning that disrupt outdoor plans and evening travel. The Wednesday morning commute may be slippery, especially north of I‑94 where that wintry mix and light snow could stick just enough to cause problems.

Boaters should also keep a close eye on conditions. Small craft advisories were in effect early Monday for parts of Lake Michigan, and winds are expected to turn gusty Tuesday night into Wednesday. Anyone planning to head out on the water should double-check the latest marine forecast before leaving the dock.

Plan Ahead

Enjoy the warm, sunny window today, but keep the umbrella and winter gear within reach. Pack rain gear for Tuesday night and allow extra time for travel Tuesday night and Wednesday morning in case storms or slick roads slow things down.
