St. Louis woke up Monday, February 23, 2026, to a gray, midwinter chill, with cloudy skies and temperatures stuck in the mid teens. Afternoon readings are expected to crawl up to around 31°F, with northwest winds near 5 to 15 mph and gusts up to about 23 mph. Skies should trend mostly sunny later in the day, then turn mostly clear overnight as temperatures dip back to around 22°F. The real plot twist arrives Tuesday, February 24, 2026, when a sharp warmup sends highs into the low 50s and turns the afternoon noticeably breezy.
Tuesday Warmup and Gusty Winds
Southerly return flow ahead of an approaching cold front is set to boost temperatures to around 53°F on Tuesday, with south winds in the 12 to 17 mph range and gusts that could peak near 30 mph. Forecast guidance hints that some localized stronger gusts may develop before the front moves through, which could make Tuesday afternoon a bit tricky for outdoor plans. These details come from the National Weather Service St. Louis.
Elevated Fire Danger Tuesday
That warm, dry air teaming up with those gusty winds will create an elevated fire danger across much of the bi state on Tuesday. Outdoor burning is discouraged, since even small sparks can spread quickly through dry grass or brush. If you are planning yard work or firing up the grill, secure loose debris, fully extinguish smoking materials, and keep water or a hose close at hand to cut down the risk.
Late Week Rain Chance
A weak system may bring rain likely from Wednesday night into Thursday morning (February 25 to 26, 2026), with a slight chance of thunderstorms mainly over the Ozarks. Most of the metro is expected to see only light, beneficial rainfall. After that, the pattern turns dry and warmer through the end of the month, although day to day temperatures may still bounce around a bit across the region.
