Milwaukee is waking up Tuesday to clear skies, low-70s temperatures and plenty of humidity, with patchy fog possible before 8 a.m. The fog should fade by midmorning as sunshine takes over, but the city is headed for a hot afternoon near 88 degrees. Heat indexes could climb into the mid-90s, with upper 90s to near 100 possible in sunnier spots.
Fog Fades Before Tuesday Heat Builds
The National Weather Service Milwaukee/Sullivan forecast calls for a slight chance of rain showers between 1 and 4 p.m., but the odds are only about 20%, so most of the day should stay dry. Southwest winds will run from 0 to 10 mph, with partly sunny skies helping temperatures reach their peak during the afternoon.
Tuesday night will remain warm and sticky, with a low around 74 and mostly cloudy skies. A slight chance of showers or thunderstorms is possible before 7 p.m., making for a few isolated interruptions rather than a widespread washout, according to the National Weather Service.
Storm Chances Increase Wednesday Through Friday
Wednesday will be another hot day near 88 degrees, with a small chance of afternoon showers or thunderstorms and a better chance of storms Wednesday night. Thursday brings a cooler high near 83 but a 50% chance of showers and thunderstorms, while Friday stays unsettled with a high around 84 and another 50% rain chance.
The weather service says some storms from Wednesday evening through Friday could be stronger, with gusty winds or hail possible. Rainfall through Friday could range from a few tenths of an inch to locally higher totals, so outdoor plans may need a backup option even though dry stretches are expected between storms.
Weekend Brings Cooler Temperatures
Temperatures ease back this weekend, with a high near 80 on Saturday and 79 on Sunday, though both days carry a 30% chance of showers or thunderstorms. Labor Day on Monday, September 7, looks cooler near 75 degrees with only a slight shower chance.
Boaters should note that Dense Fog Advisories are posted for portions of Lake Michigan through Tuesday afternoon, with expiration times varying by zone. No watches or warnings are listed for Milwaukee County on land, but drivers encountering morning fog should slow down, use low-beam headlights and leave extra following distance.
The latest forecast sharpens the outlook after an earlier Hoodline forecast highlighted the broader warm-and-stormy pattern. For Milwaukee, the practical takeaway is simple: Tuesday is the hottest day of the stretch, while the best chance for recurring rain arrives Thursday and Friday.
