Green Bay, WI – A brittle chill hangs over Wisconsin this morning, with the mercury near 19°F and frost glinting under dawn’s pale light. Winds sweep softly off the bay, carrying that unmistakable early-winter edge as Thanksgiving week begins to take shape across the state.
According to the National Weather Service in Green Bay, calm weather holds through Sunday, but changes arrive quickly Monday. Clouds increase with a slight rain chance by afternoon, followed by a 90% likelihood of steady rain late Monday night. Wet pavement and gusty winds could slow travel across Highways 41 and 29, especially during evening commutes.
By Tuesday, showers continue with highs near 52°F before colder air presses in midweek. Temperatures drop sharply Tuesday night as a new front slides across the Great Lakes. Wednesday’s highs may struggle to reach the upper 30s, and forecasters are eyeing a developing mix of rain and snow — a classic “Thanksgiving tease” that could leave slushy roads and reduced visibility for early travelers.
Thanksgiving Day itself looks dry but brisk, with highs near 33°F under mostly sunny skies — good for family drives, but cold enough for frost by evening. Beyond the holiday, long-range models hint at a broader winter push stretching from the northern Plains through the Midwest, with chances for heavier snow from November 25 through early December. Travelers returning home after the holiday should stay alert for regional winter weather developments.

- Sunday: Increasing clouds, high 48°F
- Monday: Rain likely late, high 52°F
- Tuesday: Rain, high 52°F
