Green Bay, Wisconsin – Roads north and west of the Fox Valley could turn snow-covered before midnight, and drivers along I-41 and US-29 should prepare for a slow, slippery Friday morning commute as heavy wet snow develops.
According to the National Weather Service in Green Bay, rain and a wintry mix will transition to all snow late tonight, with the heaviest precipitation falling between midnight and 9 a.m. Friday. A narrow band of heavy wet snow is expected to set up from central into northeast Wisconsin, where 2 to 6 inches may accumulate by noon Friday.
The highest totals are projected north and west of the Fox Valley, including Wausau, Stevens Point and Rhinelander. Snowfall in these areas could reach 4 to 6 inches, especially along I-39 and Highway 29, where visibility may drop below one mile during heavier bursts.
In Green Bay and Appleton, totals closer to 2 to 4 inches are likely, but the wet nature of the snow may quickly coat bridges and untreated roads along I-41 and Highway 441. Slushy conditions could worsen before sunrise as temperatures dip toward freezing.
Forecasters note some uncertainty in the exact placement of the heaviest band, meaning totals could shift slightly east or west overnight.
Drivers should allow extra time Friday morning, reduce speed on snow-covered roads and check Wisconsin 511 for live traffic updates. Snow tapers from west to east late Friday morning, but slick conditions may persist into the midday hours. Additional advisories remain in effect until noon Friday.
