Madison, WI – An Arctic blast will surge across Wisconsin beginning Saturday, November 30, bringing the coldest conditions of the season and creating potentially hazardous travel for drivers along major interstates through the first week of December.
According to the National Weather Service, a strong Arctic front moving in from Canada will push temperatures well below seasonal averages across the Upper Midwest. The Climate Prediction Center forecasts a 60–80% chance of below-normal temperatures statewide, with overnight lows in the single digits and wind chills as low as -10°F in northern regions.
Drivers traveling along I-94 and I-43 should expect icy pavement, drifting snow, and low visibility during the morning commute Monday and Tuesday. Forecasters caution that rapid freezing could occur on untreated roads, especially in open rural stretches between Madison, Milwaukee, and Green Bay.
This Arctic surge marks the first true winter outbreak for Wisconsin, following a mild November. The cold pattern is expected to linger into mid-December, while southern portions of the U.S. remain unseasonably warm.
Residents are encouraged to take winter safety precautions, including checking heating systems, preparing emergency vehicle kits, and limiting time outdoors during peak wind chill hours.
