MADISON, Wis. – NOAA’s Winter 2025–2026 outlook, released Thursday, Oct. 16, signals a harsh, snow-packed stretch for Wisconsin, with repeated snow systems and Arctic outbreaks expected from January through March. The Climate Prediction Center’s data shows above-normal precipitation and below-normal temperatures across the Upper Midwest — a classic La Niña signature that favors lake-effect bursts and deep cold.
According to the National Weather Service in Milwaukee/Sullivan, “This winter setup supports frequent clipper systems and sustained cold air. We could see a very active pattern through late February.” Northern and western counties — including Eau Claire, Wausau, and Superior — are forecast to see the heaviest snow totals, while southern zones like Madison and Milwaukee could see alternating snow and icy mixes.
January looks to bring the season’s first prolonged deep freeze, with wind chills dropping below zero during Arctic surges. Lake-effect snow could enhance totals along the Lake Michigan shoreline, while interior areas face drier, powdery snow and dangerous travel on I-39, I-43, and I-94.
Forecasters say the cold pattern may linger into March, with the possibility of late-season snowstorms delaying the thaw across northern Wisconsin. Residents are urged to prepare now — inspect heating systems, stock fuel and salt, and ensure vehicles are winter-ready.
For Wisconsin, Winter 2026 looks long, cold, and snow-heavy — a return to old-fashioned winters where preparedness, patience, and caution on icy roads will be key.
