Wisconsin starts the day locked in deep winter, with frozen roadsides and a sharp wind cutting across open stretches. The air feels brittle, breath clouds instantly, and even short trips outside demand layers. This is one more harsh December morning before a notable pattern change begins.
According to the National Weather Service in Green Bay, bitterly cold temperatures and wind chills continue today, keeping conditions dangerous for prolonged outdoor exposure. Afternoon highs range from 4° to 16°, while wind chills remain below zero at times. Extra caution is advised for early travel, outdoor workers, and anyone without adequate cold protection.
Relief starts to show up Monday, though winter doesn’t fully loosen its grip. Light snow is possible across northeast Wisconsin Monday morning, with up to 1 inch of accumulation in spots. While snowfall amounts stay modest, even light snow can create slick stretches on untreated roads, bridges, and ramps during the morning commute.
By Tuesday, temperatures finally climb above freezing for the first time this month, reaching the mid to upper 30s. Snow piles begin to soften, and travel conditions improve for most of the day. However, drivers should remain alert for refreezing after sunset where moisture lingers.
The bigger travel concern arrives midweek. Forecast models point to a clipper system Wednesday into Thursday, bringing a rain and snow mix. As temperatures hover near freezing, rain freezing on contact is possible, leading to patchy ice and slippery roads, especially during the evening and early morning hours.
This evolving setup comes as holiday travel begins to ramp up across Wisconsin. Residents should monitor updates closely, plan extra travel time midweek, and prepare vehicles for changing winter conditions.
