MILWAUKEE, WI – Fall’s bite is edging closer this Monday morning as Wisconsin wakes to a calm, crisp start that won’t last long. A chain of wet systems is on the move, promising gusty winds, soaking rain, and a sharp cooldown by midweek—setting the stage for the state’s first widespread frost later this week.
According to the National Weather Service in Milwaukee/Sullivan, showers will spread into southern Wisconsin by late Monday, becoming heavier Tuesday as winds whip up from the southwest. Gusts along I-94 and I-43 could top 30 mph at times, especially near Milwaukee, Racine, and Kenosha. Drivers should expect slick pavement and occasional standing water through Tuesday evening before drier, colder air moves in.
Temperatures will swing sharply—Monday peaks in the low 60s will tumble into the upper 30s by late Tuesday. That drop marks the arrival of a true fall cold snap, with frost likely across inland counties from Fond du Lac to Dodge and Jefferson by early Wednesday. The Hazardous Weather Outlook continues for much of southern and central Wisconsin, citing multiple frost opportunities midweek as skies clear and winds ease.
By Thursday and Friday, sunshine returns but daytime highs stay near 53 °F with nights in the mid-30s. That means frost-sensitive plants and late-season gardens could take a hit if left uncovered. Residents are urged to protect vegetation, check heating systems, and prepare for possibly freezing lows north of Madison by early Saturday—a preview of the region’s first Fall Freeze just before Halloween week.
