La Crosse, Wisconsin – Sweltering conditions will hit much of Wisconsin, southeast Minnesota, and northeast Iowa on Wednesday, as heat index values soar to 104° by the afternoon. Residents across the region are urged to take extra precautions between noon and 8 p.m., with a heat advisory issued for dozens of cities and counties.
According to the National Weather Service in La Crosse, the advisory covers Oelwein, La Crosse, Rochester, Winona, Platteville, Decorah, and many others, impacting both rural areas and city centers. High humidity, combined with temperatures in the upper 90s, will increase the risk of heat-related illnesses, especially for those without access to air conditioning.
Expect impacts on travel and daily activities, as heat can lead to road buckling and increased risk for utility interruptions. Health officials recommend avoiding outdoor work during peak heat, staying hydrated, and checking on vulnerable family, friends, and neighbors—especially the elderly and those without adequate cooling.
With the heat expected to ease after sunset Wednesday, more advisories could follow if conditions persist. Stay tuned to local emergency management and weather alerts for further updates.
