GREEN BAY, WI — Snowflakes drift through the frozen morning air as Wisconsin’s early-December chill deepens, setting the tone for a cold, slippery start to the week. The National Weather Service in Green Bay warns that light snow today into Tuesday could make roads slick across north-central and northeast Wisconsin, especially during the afternoon and evening.
Temperatures hover in the low 20s, but calm winds and near-freezing pavement mean even light snow could stick quickly to untreated surfaces. Drivers on I-41, Highway 29, and rural county routes should expect reduced visibility and icy patches late in the day. Though total snow amounts stay under an inch, it’s enough to cause trouble for commuters and anyone returning from Thanksgiving travel.
The real danger arrives midweek. Behind this system, a powerful Arctic high will push into Wisconsin, bringing wind chills between -10°F and -20°F from late Wednesday night into Thursday morning. This will be the coldest stretch since early last winter, with biting air and frost-prone conditions expected across much of the Fox Valley.
Meteorologists advise residents to bundle up, prepare vehicles for extreme cold, and watch for slick bridges and intersections as temperatures drop. Pipes, pets, and exposed skin will all be vulnerable during the late-week chill.
