St. Louis weather today brings a 70°F high with mostly cloudy skies and a 40% chance of showers and thunderstorms developing this afternoon and evening, with the strongest activity expected between 2 PM and 8 PM CT.
Here’s what our National Weather Service forecasters are tracking: a cold front that stalled near the Missouri-Arkansas border this morning is being reinforced by an approaching mid-level weather system. This setup will spark scattered showers and thunderstorms across the St. Louis area—and while most storms should remain below severe limits, a few thunderstorms across southeast Missouri and southern Illinois could produce quarter-sized hail if they organize and intensify.
If you’ve got outdoor plans around the Gateway Arch or Forest Park today, keep an eye on the sky after 2 PM CT. A packable rain jacket is your best friend right now—lightweight, easy to stash in a bag, and ready when those afternoon storms roll through. The good news: winds will stay light at around 6 mph from the north, so it won’t be a particularly windy day.
For tonight, expect heavier rain and thunderstorms between 8 PM and 5 AM CT, with an 80% chance of precipitation. Lows will dip to around 52°F. If you’re heading to any evening events—like the Ethel Cain - The Willoughby Tucker Forever Tour at The Factory tonight or David Byrne’s Who is the Sky Tour at the Stifel Theatre—bring an umbrella and allow extra time for wet roads.
Looking ahead: Wednesday will be your best day of the week. Mostly sunny skies, a high near 65°F, and just a 2% rain chance make it ideal for yard work, golfing, or catching a show. Thursday looks pleasant too, with highs around 68°F.
If you’re planning to tailgate before the St. Louis Cardinals vs Los Angeles Dodgers on May 1st at Busch Stadium, note that Friday’s forecast is shaping up nicely—though you may want to grab Official team gear on Fanatics and check Get tickets on SeatGeek for the best deals.
For tonight’s indoor dinner, comfort food is calling. A warm bowl of beef stew or chili hits different on a rainy evening. Toss ingredients into a programmable slow cooker this morning, and dinner will be ready when you get home. You can order groceries on Amazon Fresh to stock up on beef, beans, and vegetables—plus grab an enameled cast iron Dutch oven if you want to level up your rainy-day cooking game.
Stay safe on wet roads, and keep that umbrella handy through tomorrow morning!
