La Crosse, Wisconsin – Hazardous Arctic wind chills are expected to return to the La Crosse area late Sunday night and persist into Monday morning, renewing concerns for frostbite and prolonged cold exposure.
According to the National Weather Service in La Crosse, wind chills will slowly improve during the day today as winds ease. However, forecasters warn that increasing winds Sunday night into Monday will cause wind chills to rapidly deteriorate once again.
Forecast data shows wind chill values dropping into the −20 to −35 degree range across the La Crosse area during the peak impact window from Sunday night through Monday morning. At these levels, frostbite can occur on exposed skin in as little as 10 to 15 minutes.
The National Weather Service emphasizes that while air temperatures may not be at their coldest of the season, stronger winds will significantly increase the danger. Overnight and early-morning hours are expected to pose the highest risk, particularly for anyone outdoors without adequate protection.
Residents are urged to dress in multiple warm layers, cover exposed skin, and limit time outdoors during peak cold periods. Pets should be brought indoors, and residents should check on neighbors who may lack reliable heat.
Drivers are advised to carry winter emergency kits, including blankets, extra clothing, and a charged phone, in case of vehicle trouble. Even short delays outdoors can become dangerous quickly in extreme wind chills.
Those most vulnerable include older adults, young children, people experiencing homelessness, and outdoor workers. Students and young workers commuting early Monday morning may face the most severe exposure during the coldest conditions.
While wind chills are expected to gradually improve later Monday as winds decrease, below-normal temperatures are likely to persist into next week.
The National Weather Service advises residents to continue monitoring updates as Arctic conditions evolve across western Wisconsin.
