Wisconsin – Breath turns visible almost instantly this morning as winter arrives with sharp clarity across southeast Wisconsin. The cold bites early, sidewalks creak under boots, and parked cars wear a thin crust of frost. It looks calm, but conditions are already primed to change.
According to the National Weather Service in Milwaukee, temperatures hover in the teens this morning with wind chills near zero. Sunshine helps highs recover only into the upper 20s today. Tonight, clouds increase and light snow becomes possible, especially north of I-94 and U.S. 18. Even minor accumulation could make untreated roads slick by early Monday.
Light snow may linger into Monday morning north of Milwaukee, with a chance for freezing drizzle mixing in. That combination is subtle but dangerous. Bridges, ramps, and shaded stretches can glaze quickly, even with minimal snowfall. Drivers should plan extra time on I-94, I-43, and local county roads.
By Monday afternoon, temperatures climb into the upper 30s as winds turn southerly. That warming trend continues Tuesday, pushing highs into the lower 40s and improving road conditions. To be fair, this quick shift from deep cold to mild air is a classic early winter signal. When surfaces thaw by day and cool again at night, flash freezing becomes a concern.
Midweek brings quieter weather as Christmas travel ramps up. Clouds linger Wednesday with a slight chance of rain. Christmas Day stays mostly cloudy and milder, with highs in the mid-40s and no significant winter weather expected locally.
Winter has arrived, even if it loosens its grip briefly. Slow down on slick roads tonight, watch bridges closely, and stay alert as conditions evolve. Seeing snowflakes or icy spots where you are?
