Saturday, March 21, Milwaukee is waking up under patchy fog, especially in low-lying spots, and a chilled start in the mid-30s. By afternoon, though, it will feel much more like spring. Inland highs are headed for the upper 60s, with some neighborhoods flirting with 70°F as the day turns brighter and noticeably milder, as per the National Weather Service.
Afternoon Winds Pick Up
The warmth comes with a catch: the wind. South to southwest breezes will crank up by midday and turn gusty through the afternoon, with the strongest gusts expected along the lakefront. Gusty southwest winds this afternoon and early evening may reach Small Craft Advisory levels for nearshore waters, so boaters are urged to secure loose gear and double-check marine conditions before heading out, according to the National Weather Service Milwaukee/Sullivan.
Late Night Into Sunday
A cold front swings through Saturday evening, bringing about a 20–30% chance of light rain late Saturday night into Sunday morning. On the back edge of the system, the coolest spots could see a brief mix of light snow before things taper off. Temperatures slip into the upper 30s Saturday night and only rebound to around 40–42°F on Sunday as north winds increase, per the NWS forecast discussion.
Sunday Winds And The Week Ahead
Sunday will feel like a different season, with noticeably cooler air and north winds that could gust up to 30 mph in exposed spots. By Sunday night, lows dip to the upper 20s. High pressure then nudges in on Monday, bringing sunnier, calmer conditions with highs near 41°F. Additional chances for light rain are on the table later in the week, so anyone planning evening events, lakefront walks, or time on the water should keep an eye on updated forecasts.
