Green Bay and much of northeast Wisconsin are expected to see rapidly changing winter weather conditions today, according to the National Weather Service in Green Bay, as rain transitions back to snow later this afternoon and evening.
The threat for freezing precipitation early this morning has largely ended as air and road temperatures have risen above freezing across the region, including northern Wisconsin. However, attention now shifts to the afternoon and evening hours, when precipitation is expected to change from rain to snow as colder air moves in behind a passing system.
As this transition occurs, gusty winds will increase, which may cause sudden reductions in visibility at times, even though overall snow accumulations are expected to remain light. These bursts of snow, combined with stronger winds, could make travel conditions deteriorate quickly, especially during the late afternoon and evening commute.
Behind the snowfall, temperatures are forecast to fall rapidly, raising concerns for flash freezing on any untreated or wet road surfaces. Bridges, overpasses, side streets, and parking lots are particularly vulnerable to developing icy spots as temperatures drop. Even areas that appear merely wet earlier in the day may turn slick in a short amount of time.
The National Weather Service advises drivers to remain alert for rapidly changing road conditions, slow down, and increase following distances. Motorists should be prepared for slick travel conditions developing this evening and overnight, especially in areas where snow showers briefly intensify.
Snow is expected to taper off later tonight, with only limited additional accumulation after midnight. However, colder temperatures will persist, allowing icy conditions to remain into early Friday morning. Residents are encouraged to stay weather-aware, monitor updated forecasts, and use caution if traveling as winter conditions return to northeast Wisconsin.
