Green Bay, Wisconsin — Bitter cold will continue across northeast Wisconsin through the work week, with subzero wind chills each morning and a low-end chance for lake effect snow impacting travel near Lake Michigan late Thursday night into Friday.
According to the National Weather Service in Green Bay, mainly dry conditions are expected through the weekend. However, forecasters are monitoring the potential for lake effect snow near Lake Michigan, especially Thursday night into Friday, with occasional impacts possible in Vilas County and lakeshore areas.
Temperatures will remain well below normal through Friday, with highs running 10 to 20 degrees below average. Overnight lows will frequently drop into the single digits and teens below freezing, while subzero wind chills are likely each morning, especially during early commutes.
Road conditions may be affected by the cold alone, even without widespread snowfall. Extremely cold pavement temperatures can cause slick spots to develop quickly, particularly on bridges, overpasses, and untreated roads along I-43, I-41, and U.S. 141. Any lake effect snow showers that do develop near Lake Michigan could briefly reduce visibility and coat road surfaces.
The National Weather Service notes that some relief from the cold is expected this weekend, as daytime highs climb into the upper teens to mid-20s. Despite the modest warm-up, overnight temperatures will remain cold enough to maintain icy conditions in shaded areas.
Residents are urged to dress in layers, limit skin exposure during the coldest parts of the day, and take precautions to protect pets and pipes. Drivers should allow extra time during morning travel and remain alert for rapidly changing road conditions, particularly near the lakeshore.
Students, early-shift workers, and commuters traveling along I-43 near Lake Michigan should closely monitor forecast updates late this week as confidence increases regarding any lake effect snow development.
