Wisconsin wakes beneath a sharp, star-filled sky as a cold northwest wind skims over open fields and frost clings to windshields from Green Bay to De Pere — a clear early sign that Winter Weather conditions are tightening today. Pavement feels crisp underfoot, and the air carries that biting stillness that often arrives before a heavier snow push. With Post-Thanksgiving travel rising, residents should prepare for fast changes in road conditions through Saturday night.

According to the National Weather Service, a Winter Storm Watch remains in effect from Saturday morning through late Saturday night for Green Bay, Appleton, Sturgeon Bay, Oconto, Manitowoc, Waupaca, and surrounding counties. Meteorologists expect 5–9 inches of accumulating snow, with winds gusting near 20–25 mph, which may drop visibility quickly — especially along I-43, Highway 41, and Highway 29.
Travelers should plan ahead and watch for abrupt slowdowns once snow bands strengthen Saturday.

Clouds increase today, and a light snow chance may develop later as moisture deepens. The steadier snow arrives Saturday morning, when colder air meets an energetic wave pushing east. Bands may fluctuate in intensity, but the region looks primed for several hours of moderate to heavy snow by afternoon. To be fair, snow placement may shift, but northeast Wisconsin remains centered in the higher-impact corridor.

Saturday night brings continued snow and gusty winds, creating pockets of low visibility and scattered slick spots where slush refreezes. Sunday finally turns brighter, with highs near 30°, though shaded stretches and rural highways may stay icy.

This storm also marks a Winter Tease heading into early December. Long-range models highlight a December 2–6 cold front that could plunge temperatures well below normal from the Midwest to New England, with additional flurries or light snow chances — something holiday travelers should monitor closely.
