Overview: Milwaukee’s 5-Day Weather Forecast March 30, 2026, sees sunshine and 60s before gusty winds and heavy thunderstorms overtake the forecast, with possible snow later in the week.
Today: The work weeks starts beautifully with 50-degree temperatures and sunny skies. Winds change and clouds increase however, as northeastern winds from Canadian pressure systems overcome the warm southern air. Milwaukee tops out at 68 in the early afternoon, and by 3 p.m., temperatures drop to 49. Due to this cold front, fog could decrease visibility near the lakeshore into the night.
Tonight: Around 8 p.m., temperatures bottom out at 40 degrees while a low-pressure system moves into Wisconsin, producing precipitation. From 9 p.m. until 1 a.m., thunderstorms weave through Southeastern Wisconsin. This brings wind gusts up to 40 mph, possible hail, and heavy downpours accumulating to a quarter inch of rain. The weather calms down in the late night while temperatures hesitantly rise into the high 40s.
Tomorrow: Southwestern winds of 14 mph boost temperatures higher into the 60s, but the low pressure’s cold front passes through Wisconsin. Some rain might fall in the late morning, but thunderstorms arrive around lunchtime with the cold temperatures. From 11 a.m. to 3 p.m., the storms send Milwaukee high winds, possible hail, heavy rain, and 40-degree temperatures. Clouds break afterwards only to be succeeded by another round of rain in the late evening. During the night, northwestern winds of 15 mph gust up to 30 mph as partly cloudy skies pass over Milwaukee. Temperatures drop to 41 degrees by Wednesday morning.
Extended: For April Fools’ Day, Wisconsin weather plays a bummer of a trick on Milwaukee and drops temperatures into the 30s. Despite broken clouds, temperatures remain there until dinnertime due to constant 12-mph northeast winds and 30-mph gusts. In the early night, temperatures begin rising slightly with the passing of another storm system. Freezing temperatures aloft could induce brief snow and freezing rain in the first few hours of precipitation. This turns into a heavy rain which leaves Thursday night. Temperatures Thursday reach the 40s in the late night and continue to rise to 50 Friday morning. As another low-pressure system poises itself for a trip through the Midwest, Friday could see some precipitation later. Please stay up to date with your forecasts, as this week is full of active weather.
