GREEN BAY, Wis. – A sharp November chill is settling over Wisconsin as the first taste of winter tightens its grip heading into Sunday. Temperatures that reached the 50s earlier this week will tumble steadily through the weekend, and a cold rain Friday may mix with wet snow by Saturday in parts of northeast Wisconsin. Motorists traveling along I-41 and U.S. 29 should prepare for slippery spots and reduced visibility during the transition.
According to the National Weather Service in Green Bay, scattered sprinkles and light rain will develop Saturday morning, followed by a rain-snow mix through the afternoon as colder air sweeps in from the northwest. Winds will gust up to 25 mph, adding a bite to the air and blowing stray flakes across rural roads and open fields. Light accumulations remain limited, but the shift marks an early sign of the winter pattern setting in across the Upper Midwest.
By Sunday, highs struggle to reach the upper 30s with scattered snow showers north of Lake Winnebago and into Door County. Residents planning outdoor Veterans Day events or early holiday errands should dress warmly, secure decorations, and allow extra time for travel. The brisk pattern lingers into early next week as a broad Arctic dome settles over the Great Lakes.
Farther south, mild air retreats toward Illinois and Iowa, signaling that the broader November cooldown may extend across much of the central U.S. by Veterans Day. For now, Green Bay’s weekend brings a clear message: Fall’s colors are fading fast, and winter’s chill is already knocking.
