St. Louis sees mostly cloudy skies and a high near 82°F on Friday, May 29 — a comfortable late-May day before evening thunderstorm chances move in. If you have outdoor plans tonight, here’s the timing you need to know.
Today’s Setup
East winds at 3 to 8 mph keep things mild through the afternoon, with just a 9% chance of rain during daylight hours. A slow-moving trough is tracking east across Missouri, and the National Weather Service notes the highest storm chances today are concentrated over central and southeast Missouri — keeping St. Louis relatively quiet until this evening. Make the most of the dry afternoon: mow the grass, head to Forest Park, or take the family down to the Gateway Arch grounds before clouds thicken.
Evening Storm Risk
After sunset, storm chances jump to 40% overnight. The Weather Prediction Center flagged the Middle Mississippi Valley for locally heavy rainfall — forecasters note PWAT values of 1.6 to 2.0 inches, meaning any storm that fires could drop a quick, intense downpour. The National Weather Service sees no organized severe weather threat, but keep a weather app with lightning alerts handy if you’re heading out tonight.
Cardinals-Cubs at Busch Stadium
It’s a big series at Busch Stadium — the St. Louis Cardinals vs. Chicago Cubs runs Friday through Sunday. Tonight’s first pitch falls right in the window when storm chances start climbing, so tailgaters should pack a pop-up canopy tent with weights for the parking lots. Saturday and Sunday each carry 30% storm chances as well. Deck out in a St. Louis Cardinals jersey or St. Louis Cardinals fitted cap, and Find tickets on StubHub if you still need seats for the series.
Fishing Window
Friday morning is the sweet spot for anglers — calm east winds and stable pre-storm pressure make for a solid bite on the Mississippi and Meramec rivers. A tackle storage kit keeps you organized on the water. Need to restock lures? Check out the Strike King crankbait deals at Bass Pro Shops.
Tonight’s Events
The Battlehawks host the Dallas Renegades at The Dome at America’s Center tonight — fully indoors, so no weather concerns. Les Claypool plays The Factory on Saturday night; grab a Les Claypool t-shirt and Find tickets on StubHub before they sell out.
Grill Tonight
This evening is your best grilling window before the storms arrive. Fire up burgers or grilled chicken with corn on the cob — and check our guide to smoking tri-tip like brisket if you want to step it up. A reliable instant-read meat thermometer and a grill brush and scraper set are must-haves at the grill. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Saturday brings partly sunny skies with a near-81°F high and 30% storm chances in the afternoon and evening. Sunday warms to near 83°F with lingering storm chances. The National Weather Service says dry time will be plentiful between rounds, and temperatures remain seasonable through early next week.
