Milwaukee woke up to a muggy start on Saturday, May 16, 2026, with temperatures hovering around 63°F and dew points near 59°F. It was a sticky morning for early walkers and commuters, with a few spotty showers possible before 7 a.m. After that, skies are expected to trend mostly sunny and the city should climb into the mid 80s by afternoon. West winds will stay on the lighter side at about 5 to 10 mph through the day.
Today: Mostly Sunny After Early Showers
That early slight chance of rain before 7 a.m. on Saturday will be brief, and the rest of the day looks mostly sunny with a high near 84°F. The soggiest pockets in the morning could see a quarter to a half inch of rain, with west winds in the 5 to 10 mph range. The National Weather Service office in Milwaukee had a severe thunderstorm watch in effect overnight for parts of southern Wisconsin and expected storms to shift into Lake Michigan by dawn, according to NWS Milwaukee.
Sunday: Showers And Thunderstorms Likely
Sunday, May 17, 2026, looks more unsettled. Along the lakeshore, clouds will keep highs in the low to mid 70s, while inland neighborhoods warm into the low to mid 80s. Rain showers are likely before 10 a.m., with showers and thunderstorms most likely between 10 a.m. and 2 p.m. Southwestern and inland counties have the better shot at stronger storms, although timing and exact placement are still a bit fuzzy.

Monday Into Tuesday: Warm, Gusty And Active
By Monday, May 18, 2026, an even warmer and more humid air mass moves in, sending highs to around 86°F with south winds of 10 to 15 mph. Showers and thunderstorms are likely in the afternoon and evening, and some storms could bring gusty winds along with locally heavy downpours. Tuesday, May 19, 2026, keeps the storm chances going, with stronger southwest winds and gusts up to about 30 mph in spots before a midweek cooldown. A shift to noticeably cooler and quieter weather is expected on Wednesday and Thursday, according to NWS Milwaukee.
Plan Ahead
If you have outdoor plans from Monday into Tuesday, it is wise to line up an indoor backup, tuck away or secure loose patio furniture before the winds pick up, and keep an umbrella close for quick-hitting downpours. Boaters should be extra cautious, since overnight gale and small-craft headlines affected parts of Lake Michigan, and commuters should keep an eye on local service alerts along with the latest forecasts before heading out.
