Within the 5-Day Weather Forecast March 21, 2026, a rollercoaster of temperatures awaits Milwaukee, complete with higher winds, possible snow and rain.
Today: Saturday starts with a heavy fog before 10 a.m., and temperatures sleepily rise along with the sun. Once the fog lifts, Milwaukee greets steady southern winds of 12 mph with gusts peaking at 25 mph. These winds carry temperatures up to 61 by the afternoon, but if clouds stay away and winds enter correctly, this could be higher. High clouds put a semi-haze over the sun, and lower clouds fill in later.
Tonight: With gathering clouds and turning winds in the night, temperatures plummet into the 30s. Northern winds increase to 15 mph with gusts up to 38 mph and maintain their intensity through the Sunday.
Tomorrow: In the early morning, drizzles arrive with the passing of a low-pressure system. This turns to rain with some freezing rain and snow possible in the late morning, ending around 2 p.m. Deteriorating road conditions remain a concern, so exercise caution when traveling. Temperatures try to rise, but with the stubborn wind, they continue to drop. As clouds dissipate in the evening, temperatures hit the 20s and sink to 23 for a low. Thankfully, winds calm later, allowing higher temperatures on Monday.
Monday: The morning and evening commute pass without inclement weather, only frequented by scattered clouds. Otherwise, the first day of the work week and UW-Milwaukee’s spring break week sees a cool 40-degree high in the afternoon. As high pressure settles over Wisconsin, winds vary over the day, finally deciding on the southeast towards the night.
Extended: Precipitation chances return Tuesday in the morning and later Wednesday with the fluctuation of pressures and winds. Despite this, temperatures reach the 50s both days, increasing lows from the 30s to the 40s. Winds increase, too. From an average 9 mph to 11 mph Wednesday, mid-week winds gust up to 24 mph, strengthening through Wednesday night. A strengthening low-pressure system knocks on Milwaukee’s door, awaiting entrance in the second half of the week, so keep up to date with your forecasts!
