St. Louis is starting Friday with a chance of showers and thunderstorms before 10 AM CT, then partly sunny skies and a warm high near 85°F the rest of the afternoon. South winds of 9 to 13 mph with gusts up to 21 mph keep it breezy and humid — very much a May day in Missouri. If you can wait out the morning, the day gets a lot more cooperative.
Today’s Setup
The National Weather Service in St. Louis notes that early storm activity is elevated well above the surface, meaning the primary threat with any morning thunderstorms is hail up to 1 inch, with a lesser risk of damaging gusts. That coverage should fade by around 10 AM CT as the overnight energy that fueled it diminishes. Forest Park, the Arch grounds, and your backyard all look fine by midday. Tonight stays mostly cloudy with a low around 67°F and just a 20% chance of late storms creeping back after 4 AM.
Best Window To Be Outside
Late morning through early evening is your sweet spot. If you have storm-downed branches to deal with, this afternoon is a good window to break out a chainsaw 18 inch and clear the yard before Saturday’s heavier weather arrives.
Tonight: Kid Rock and Dayseeker
Kid Rock brings the Freedom 250 Tour to Hollywood Casino Amphitheater tonight — it’s an outdoor venue, so dress for warm and breezy. A Kid Rock t-shirt handles the temperature just fine, but tuck a light layer in your bag for later in the evening. Dayseeker plays The Pageant tonight, which is indoors — no weather worries at all there.
Saturday: Storms in the Morning, Big Events on the Line
Saturday raises the stakes with a 60% chance of storms. The National Weather Service expects the heaviest activity between 8 AM and noon CT, tapering off by early afternoon. If you’re headed to Pointfest at Hollywood Casino Amphitheater, plan for a wet arrival — bring a rain jacket and check the timing before you leave.
The Cardinals host the Kansas City Royals at Busch Stadium on Saturday for Stan Musial Military Bobblehead Day. Morning storms will make tailgating dicey, but game-time weather looks better as storms wind down. Pack a St. Louis Cardinals jersey and a St. Louis Cardinals fitted cap, and tuck a poncho in your bag just in case. Still need seats? Find tickets on StubHub while they’re available.
Rain, Wind, and Flood Risk
Flash flood risk today is very low — the Weather Prediction Center puts the chance of excessive rainfall below 5%. The more significant concern is next week: the National Weather Service is tracking a cold front expected to push through the region somewhere between Monday and Wednesday, bringing a greater severe weather threat. Exact timing and strength remain uncertain, so keep your St. Louis weather forecast bookmarked and check back often.
Comfort Food for a Rainy Friday Night
A stormy morning and a muggy evening call for slow cooker comfort food. Load up a programmable slow cooker with chili or beef stew before you head out and come home to dinner ready to go. Prefer stovetop? An enameled cast iron Dutch oven is perfect for a big pot of soup. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Saturday’s storms should clear by early afternoon, leaving a high near 85°F for the afternoon and evening. Sunday looks calmer — a solid day to catch the Cardinals wrap up their series against the Royals at Busch Stadium, or head to The Factory for Freddie Gibbs. Early next week, watch for a more active severe weather pattern as that cold front moves in. Browse outdoor gear deals now if you want to be ready before conditions escalate.
