Chicago, Illinois – Millions across the Midwest are bracing for dangerously high temperatures and oppressive humidity as widespread heat advisories remain in effect from the National Weather Service through Thursday evening. Heat index values are expected to soar as high as 110 degrees in cities including Chicago, St. Louis, Des Moines, Milwaukee, Indianapolis, and Kansas City, raising concerns for public safety and local infrastructure.
According to the National Weather Service, heat advisories stretch from central Iowa and northern Missouri to southern Wisconsin, central Indiana, and northern Arkansas, with the worst conditions expected from noon Wednesday through at least 8 p.m. Thursday. Cities like Chicago will see stifling heat linger overnight, offering little relief even after sunset.
Area schools, outdoor activities, and major roadways including I-55, I-70, and I-80 may see delays or early closures as public health agencies urge residents to avoid non-essential travel during peak heat. Utility companies in St. Louis and Indianapolis are preparing for potential power surges as demand for air conditioning spikes, while city officials across the region open cooling centers and extend pool hours.
Residents are advised to drink plenty of water, avoid strenuous outdoor activity, check on elderly neighbors, and never leave children or pets in vehicles. The current stretch of heat is among the most intense since July 2022, and with advisories likely to be updated, residents should monitor local alerts.
Heat warnings remain in effect until at least Thursday night, with additional advisories possible as the system lingers over the region. Stay tuned to local officials and the National Weather Service for the latest updates.
