Wisconsin wakes in a sharp, Arctic stillness this morning as a bitter wind cuts across frozen neighborhoods and pushes powdery snow along the curb lines. The air feels biting even through a thick coat, and exposed skin stings within seconds — a clear sign that dangerous wind chills are already taking hold across Green Bay and surrounding communities. Anyone stepping outside should plan cautiously and limit time in the open.
Very cold air dominates today as wind chills fall toward 20 to 30 below zero, with the strongest blasts building through the afternoon and deepening again Saturday night into Sunday morning. Meteorologists now warn that frostbite may occur in 10 minutes during the harshest bursts. Drivers, walkers, and transit riders should protect hands and faces before heading out, especially during errands or work shifts along Highway 41 or I-43.
Light snow remains possible through early afternoon, but accumulations stay minor. To be fair, even a dusting over hard-frozen pavement can create slick patches, especially at intersections and ramps. Watch for drifting near open fields as winds strengthen.
By Saturday, strong northwest winds reinforce the December Cold Snap, driving wind chills again toward -25°F by evening. Skies clear late, yet the temperature plunge continues. Sunday brings sun but almost no relief; families heading to youth sports, holiday shopping, or church services should prep warm layers and consider warming breaks during travel.
Models hint at a modest moderation next week, though another Winter Tease appears midweek with a small chance of light snow returning.
