The air in northeast Wisconsin feels charged this morning — thick gray clouds pressing low over the bay, flakes beginning to swirl in the headlights. A Winter Weather Advisory is in effect from 8 PM tonight through 9 AM Wednesday, marking the start of the region’s first major December snow event.
The National Weather Service in Green Bay warns that 3 to 5 inches of wet, dense snow will accumulate across Brown, Door, Kewaunee, Manitowoc, and Outagamie Counties, with isolated higher totals possible north of Highway 29. Winds will gust up to 35 mph, creating reduced visibility and slick, snow-covered roads through the Wednesday morning commute.
Travelers along I-41 and Highway 29 should plan extra time — conditions will deteriorate quickly after sunset. Wet snow may cling to trees and power lines, increasing the risk of scattered outages overnight. Meteorologists note that the snow will taper Wednesday afternoon, followed by a brief lull before the real cold sets in.
By late week, an Arctic air mass dives south, sending wind chills plunging to 10–30 below zero Friday into Sunday. The pattern remains active, with another weak clipper system possibly brushing the region late this weekend or early next week.
