Milwaukee is starting Sunday under cloudy skies and sticky air, with temperatures around 75°F early and a high near 85°F ahead. A patch of morning fog could briefly reduce visibility, but the bigger story is a turn toward sunnier, cooler weather Monday before storm chances return Tuesday.

Fog First, Then A Warm Afternoon

Patchy fog is expected between 7 and 8 a.m., followed by partly sunny skies through the afternoon. West winds will run around 5 to 10 mph and may feel breezier later in the day, while scattered showers are possible near the Lake Michigan shoreline; most inland neighborhoods should stay dry.

Sunday night looks quieter, with partly cloudy skies and temperatures dropping to about 67°F. No watches, warnings or advisories are in effect for Milwaukee County, according to the National Weather Service Milwaukee/Sullivan.

Monday Is The Quiet Reset

Monday brings the week’s best weather window: sunny skies, a high near 80°F and light northwest winds. Monday night should be mostly clear, with a low around 66°F, making for a comfortable evening across the city.

Storm Chances Return Tuesday

The forecast turns more unsettled Tuesday, when a 40% chance of showers and thunderstorms arrives after 1 p.m. Temperatures will reach about 83°F, with another 40% chance of showers and storms Tuesday night and rainfall ranging from a few light sprinkles to as much as a quarter-inch.

Wednesday stays cooler, with a 30% chance of rain showers before 1 p.m. and a high near 74°F, followed by mostly sunny conditions for much of the afternoon.

Cooler Finish Ahead

Thursday looks mostly sunny and mild, with a high near 74°F and a low around 62°F overnight. Friday warms slightly to about 77°F, though a 20% chance of afternoon showers returns, followed by a chance of thunderstorms Friday night.

Saturday should end the stretch on a brighter note, with only a slight early chance of showers or thunderstorms before mostly sunny skies take over. For Sunday plans, the best bet is to wait until the morning fog lifts, keep a light rain layer handy near the lake and enjoy the warm afternoon before Monday’s cooler reset.
