Milwaukee wakes up to clear skies and a comfy 61°F at General Mitchell International Airport early Tuesday, but the quiet stretch is on borrowed time. Scattered showers could pop up this morning, with a stronger round of showers and thunderstorms expected this afternoon between about 1–4 p.m. Highs land near 71°F with southwest winds at 10–15 mph and gusts pushing close to 25 mph.
Any storms that fire this afternoon could toss down small hail and brief heavy downpours, though most neighborhoods will likely only see light totals from individual cells. The afternoon and evening commute look wet and gusty, so if the sky goes dark and lightning starts flashing, that is your cue to move outdoor plans inside.
Widespread Rain And Gusty Winds Wednesday
On Wednesday a larger, more organized system rolls in and spreads rain across the area through much of the day, with highs around 66°F. Gusts could reach about 30 mph and some pockets of heavier rain are on the table. Forecasters say the best shot at steady, longer-lasting rain comes Wednesday and Wednesday night, with localized totals up to roughly three quarters to one inch that could slow travel.
According to the National Weather Service, there is a conditional risk for stronger storms mainly south of the I-94 corridor, but that depends on the exact track of the system. Translation: keep an eye on updates if you live or work on the south side or points farther south.
Juneteenth Weekend Plans
The silver lining shows up just in time for the holiday: the forecast currently dries out by Friday, Juneteenth, with highs near 75°F and a much better setup for outdoor celebrations. Milwaukee County’s official Juneteenth Day festival at Rose Park is still scheduled for Friday, though organizers and attendees should monitor updates in case timing or rainfall totals shift. Event details are posted by Milwaukee County.
Boaters And Lakeshore
For Lake Michigan plans, Wednesday afternoon into Thursday could get bumpy. Gusty winds may turn the lake choppy and push conditions close to Small Craft Advisory criteria on Wednesday. Anyone planning to launch should check marine forecasts and think about delaying trips if conditions deteriorate. Stronger cells could also drop small hail over the lake, which is not the kind of ice you want on your deck.
How To Prepare
Now is the time to charge phones, tie down or bring in outdoor furniture, and sketch out a dry backup plan for any outdoor gatherings this afternoon and Wednesday. Avoid driving through standing water and head indoors if you see lightning. The main short-term hazards remain brief heavy downpours and localized street flooding.
