St. Louis, MO – A heat wave will grip St. Louis this Sunday, with temperatures peaking near 91°F, potentially causing hazardous conditions. With dry weather and winds gusting up to 14 mph, fire risks along I-70 in northern Missouri and west-central Illinois will remain elevated.
According to the National Weather Service (NWS), the heat wave could lead to rapid fire spread in grassy and agricultural areas. Residents in affected regions should avoid outdoor burns and secure any flammable materials. The fire risk is particularly critical in areas north of I-70, where dry conditions are expected to intensify through the weekend.
On Sunday, expect mostly sunny skies and a high of 91°F. Sunday night will bring clear skies with a low of 50°F, accompanied by northwest winds up to 8 mph. The heat will slightly ease by Monday with a high near 72°F, but dry conditions will persist. Fire officials urge caution through the middle of next week as elevated fire risks continue.
