St. Louis woke up to a sharp chill on Tuesday, February 24, 2026, with temperatures down in the low 20s. By later today, though, it will feel like a different season. Southerly winds will shove highs into the mid 50s this afternoon, with gusts that may reach 30 to 32 mph. That quick warmup on top of dry grass and brush means an elevated fire risk across much of the bi-state area, so open burning is a bad idea and loose outdoor items should be tied down or brought in. A cold front will slide through late Tuesday, with a more noticeable pattern change lining up later in the week.
Afternoon Winds Pick Up
Southerly winds will run around 9 to 20 mph this afternoon, with gusts that could spike to about 32 mph, the kind of breeze that turns yardwork and temporary structures into a hassle. According to the National Weather Service, those gusts combined with low humidity and already dry vegetation will push fire danger into the elevated category across much of the region today. If you are grilling or tackling outdoor chores, keep a hose or water source nearby and skip any brush burning.
Late-Week Rain Chance
A fast-moving system is expected to roll in late Wednesday night into Thursday, bringing roughly a 60 percent chance of light rain for much of the metro and a brief rain and snow mix possible north of I-70. Forecast guidance points to light precipitation that should be largely non-impactful for travel, although Thursday morning commutes could be on the soggy side in spots. Anyone with outdoor plans Wednesday night should plan for a damp stretch and check on conditions before heading out.
Weekend Outlook
Temperatures bounce back into the 60s by Friday and Saturday, with highs near 66 on Friday and around 68 on Saturday, before a stronger cold front approaches late in the weekend. The National Weather Service forecast discussion describes that front as potent enough to shave temperatures back and boost shower chances by Sunday into early next week. Some guidance hints at a wintry mix in northern parts of the area on Sunday, March 1, 2026. Keep Sunday plans flexible and monitor updates as the weekend gets closer.
What To Know And Do
Skip backyard burns and postpone any controlled burns while gusty south winds and low humidity hang around, and consider bringing small patio furniture and planters inside before the strongest midday gusts move in. The light rain expected late Wednesday night may take the edge off the dryness in a few spots but is not forecast to deliver a soaking, so do not bank on it to solve the fire risk. Sign up for local alerts and keep an eye on updated forecasts if you have outdoor events lined up this weekend.
