St. Louis is looking at a warm but unsettled Monday, with a high near 82°F and a 30% chance of showers and thunderstorms developing after 7 AM CT, according to the National Weather Service.
Here’s what’s happening: A cold front is pushing southward through the Midwest, and ahead of it, Gulf moisture is streaming into our area, making the air noticeably more humid than yesterday. The National Weather Service forecasters expect the best chance for storms to develop this evening—particularly north of I-70 and into northeastern Missouri and west-central Illinois—where a few storms could produce large hail. If you’re heading to Busch Stadium for the Cardinals vs. Milwaukee Brewers game today, plan for breezy southwest winds at 6 to 15 mph with gusts to 25 mph. Afternoon storms are possible but not certain, so bring a light rain jacket if you’re wearing a St. Louis Cardinals jersey or St. Louis Cardinals fitted cap.
The real soaker arrives tonight and Tuesday. Showers and thunderstorms will become likely between 7 PM and 10 PM CT tonight, with an 84% chance of precipitation overall. Temperatures will be mild, dropping only to around 56°F. Tuesday looks like a washout—the National Weather Service is calling for a 100% chance of showers and thunderstorms all day, with temperatures falling to around 57°F by afternoon. The good news: while rain will be heavy at times, the threat of flooding is very low.
If you’ve got outdoor plans today, get them done before 7 AM CT or wait until evening after any storms pass. Golf outings should be postponed to Wednesday at the earliest. The same goes for lawn mowing—the ground will be too wet Tuesday and Wednesday. However, if you need to tackle yard work, grab a ratchet tie down strap kit to secure any loose outdoor gear before the winds kick up this evening.
With two days of rain ahead, this is the perfect time to plan some indoor activities. The Dancing With The Stars: Live! - 2026 Tour is at the Stifel Theatre on Wednesday, May 6th—a great escape from the wet weather. You can Find tickets on StubHub or Get tickets on SeatGeek.
For dinner tonight and tomorrow, embrace the rainy-day comfort food vibe. A slow cooker chili or hearty beef stew is ideal—set it and forget it while the storms roll through. A programmable slow cooker makes this effortless, or go classic with an enameled cast iron Dutch oven for stovetop simmering. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Looking ahead: Wednesday brings drier air and below-normal temperatures in the mid-60s. The Cardinals play the Brewers again on Tuesday and Wednesday—Tuesday’s game will definitely be impacted by rain, but Wednesday could be playable if the storms clear by game time.
Stay safe out there, keep an umbrella handy, and enjoy the cooler stretch ahead!
