Milwaukee, WI – Residents across central and south-central Wisconsin should prepare for chilly conditions overnight as a Frost Advisory goes into effect from 2 a.m. to 8 a.m. CDT Monday, according to the National Weather Service in Milwaukee/Sullivan.
Forecasters say clear skies and calm winds will allow temperatures to dip into the mid-30s, leading to the potential for patchy frost formation by early morning. Areas near Wisconsin Rapids, Fond du Lac, and Portage are expected to see the highest frost potential, while slightly warmer conditions are forecast toward southwest Wisconsin.
Residents are urged to protect sensitive plants and outdoor vegetation from frost damage. The advisory is expected to expire shortly after sunrise Monday as temperatures rebound under mostly sunny skies.
The weather service notes that this early-season chill marks a cool start to the week, though milder air is likely to return by midweek.
