Wisconsin wakes to a sharp winter edge this morning as freezing rain coats roads with a thin, glassy glaze. Tires hiss on slick pavement, and untreated surfaces shine under streetlights across northeast Wisconsin.
According to the National Weather Service in Green Bay, a Winter Weather Advisory remains in effect through midday for Brown, Outagamie, Winnebago, and Calumet counties. Freezing rain and freezing drizzle are producing ice accumulations between one-tenth and two-tenths of an inch, especially south of Highway 29 and inland from Lake Michigan.
The morning commute is expected to be hazardous. I-41, Highway 172, and city streets around Green Bay may turn slick quickly, particularly on bridges and ramps. Drivers are urged to slow down, increase following distance, and check road conditions before heading out. With schools back in session after the holiday break, traffic patterns feel heavier than usual.
Temperatures hover near 30 degrees early, keeping ice locked in place. Conditions improve gradually this afternoon as readings climb into the mid-30s. Rain replaces freezing precipitation, allowing road treatments to work more effectively.
A quieter stretch follows midweek. Skies partially clear Wednesday, and daytime highs remain seasonable in the mid-30s. That pause will be brief.
Another system approaches late Thursday night. Rain develops first, then colder air slips in. By Friday night into Saturday, rain may change to snow across the Green Bay area. Accumulations appear light for now, but timing near freezing raises concern for slushy roads and flash freezing after dark.
Meteorologists continue tracking the late-week system as winter regains momentum during the first full week of 2026. More advisories could follow if temperatures trend colder.
