Milwaukee, WI – Residents across Milwaukee and southeastern Wisconsin should prepare for dangerous wind chills nearing –30°F early Monday morning as Arctic air sweeps across the region, according to the National Weather Service (NWS) Milwaukee/Sullivan.
The lowest wind chills are expected between 3 a.m. and 9 a.m. Monday (Jan. 19), with temperatures around –5°F to –10°F and wind gusts up to 40 mph. Conditions are expected to be most severe along the Lake Michigan corridor, including Milwaukee, Waukesha, and Racine Counties.
According to the NWS, frostbite can occur on exposed skin in as little as 10 to 20 minutes under these conditions. Officials urge residents to limit time outdoors, wear multiple warm layers, and bring pets inside overnight.
Winds are expected to gradually ease later Monday, but temperatures will remain below freezing through at least midweek. The NWS says this could be the coldest morning of the 2026 winter season so far.
