Wisconsin – Bitter cold grips northeast Wisconsin this morning as temperatures hover near 7 degrees in Green Bay. The air feels sharp, breath freezes instantly, and pavement remains stiff and unforgiving ahead of a developing winter weather threat.
According to the National Weather Service in Green Bay, a Winter Weather Advisory is in effect from later today through early Monday morning. Light snow, sleet, and freezing rain are expected to spread across the region, creating hazardous travel conditions. Snow and sleet totals of one to two inches are possible in parts of Kewaunee, Brown, and northern Manitowoc counties, with lesser amounts elsewhere. Ice accumulation may reach a few hundredths of an inch.
Conditions deteriorate quickly later today as snow develops and transitions into a wintry mix. Roads across Green Bay, De Pere, Ashwaubenon, and surrounding communities may turn slick by evening. Bridges, overpasses, and untreated roads will be especially dangerous as temperatures remain well below freezing.
Travel along I-43, Highway 41, and local roads could become difficult during the evening and early Monday commute. Slushy buildup and thin ice may reduce traction, even where snowfall totals stay modest. Drivers should slow down, increase following distance, and avoid unnecessary travel once precipitation begins.
While the wintry mix tapers early Monday, impacts may linger into the morning hours. Patchy fog and freezing drizzle could continue to create slick conditions despite improving skies. Temperatures gradually climb into the low 30s Monday afternoon, allowing some melting.
Looking ahead, the first full week of January 2026 stays active. Rain chances return by Tuesday, followed by fluctuating temperatures that raise the risk of refreezing at night. Winter’s grip remains firm across the Great Lakes, with more snow opportunities possible later this month.
