Milwaukee, Wisconsin – A colder, storm-active pattern is settling across Wisconsin as December begins, prompting a December Snow Alert while winter in Milwaukee becomes more intense. While it’s too early to determine exactly how many inches of snow could fall, one thing is certain: Wisconsin is positioned for an above-average amount as stronger systems interact with cold Great Lakes air.
According to the Climate Prediction Center, below-normal temperatures and above-normal precipitation are favored across the Upper Midwest through December. According to the National Weather Service in Milwaukee/Sullivan, that pattern commonly supports multiple storm windows, including clippers, stronger synoptic lows, and lake-enhanced snow along Lake Michigan — especially from Milwaukee to Sheboygan.
According to WisDOT, travel hazards will likely increase along I-94, I-41, I-43, and the Zoo Interchange as colder mornings promote black ice and bursts of heavier snow reduce visibility. Lake-effect bands may briefly intensify near the lakeshore when winds turn northeast or north. Drivers should carry winter kits, keep devices charged, and allow extra time on untreated roads.
Holiday events across Milwaukee, Waukesha, Racine, and the Fox Valley may face schedule adjustments if storm tracks push close enough to deepen snowfall. Residents should dress in layers, protect outdoor pipes, and prepare for power flickers if wetter snow or gusty winds stress tree limbs.
While specific totals remain uncertain this early, long-range signals continue to support a colder, storm-favorable pattern — increasing confidence that Wisconsin is headed for a snowy December and improving the chance of a White Christmas across much of the state.
