MILWAUKEE, Wisconsin – A calm, golden stretch of fall weather will carry through midweek before clouds and light rain edge back into southeastern Wisconsin just as Halloween weekend begins. East winds and mild afternoons will make for comfortable cleanup weather across the metro, but Friday night may turn damp for late-week events.
According to the National Weather Service in Milwaukee/Sullivan, skies stay mostly sunny through Thursday with highs in the lower to mid-50s. Breezes off Lake Michigan will keep the shoreline a few degrees cooler, especially from Port Washington to Racine. Winds shift northwest by Thursday night, signaling a subtle pattern change as cooler, unsettled air approaches from the Plains.
Friday begins partly sunny, but clouds will thicken by afternoon. Rain chances rise after sunset, bringing light showers across Milwaukee, Waukesha, and Kenosha counties. Drivers heading along I-94 or I-43 should prepare for slick roads and reduced visibility if drizzle develops. While rainfall totals appear light—generally under a quarter inch—it’s enough to dampen late outdoor football games or early Halloween setups.
Saturday may stay mostly cloudy with spotty showers and highs in the upper 40s, making it the chilliest day of the week. Trick-or-treat events scheduled for Friday still look favorable during daylight hours, though cooler winds will add a brisk edge by dusk.
By Sunday, a brief clearing trend returns, but the first days of November appear poised to turn sharply colder. Long-range models hint at a possible early cold snap next week—Wisconsin’s first real taste of November chill.
