A sharp December chill settles over Wisconsin this morning as crisp air sweeps across Green Bay, hinting at a developing winter pattern that may tighten its grip through the end of the week. Drivers stepping out early will notice damp, cold pavement that could freeze fast after sunset—an early-season setup known to trigger quick slick spots on residential streets and main roads alike.
According to the National Weather Service, light snow remains possible today for northern and northeastern Wisconsin, with temperatures holding in the teens and lower 20s before diving toward 1°F tonight. Wind chills fall even lower, slipping into the negative teens at times, creating a biting feel along open fields and major routes including Highway 41.
The agency notes a continued risk of slippery travel from today into Wednesday as light snow bands drift across the region. Even minor accumulations can glaze roads when temperatures oscillate near freezing during the day and rapidly refreeze after dusk. Keep coats, gloves, and a scraper in the car, and allow extra braking distance on bridges and overpasses.
Meteorologists now track a broader early December cold snap that may intensify by late Wednesday and Thursday. Models show wind chills between 10 below and 20 below zero spreading across much of the region. Another window of light snow is possible Friday into Friday night—an early sign of more active winter energy building to the west as the Great Lakes region enters prime storm season.
Plan extra time if traveling late this week, especially during the early morning and evening cool-downs when black ice forms fastest.
