St. Louis is in for a gorgeous Sunday, with mostly sunny skies and a high near 91°F — a perfect day to head to Busch Stadium, hit the links, or fire up the grill in your backyard.
Today’s Setup
South winds will run 7 to 17 mph with gusts up to 28 mph, keeping the afternoon breezy but manageable. Humidity is already climbing, so dress light and stay hydrated if you’re spending time outdoors near Forest Park or the Arch grounds. Overnight lows drop only to around 72°F, with winds staying strong at 13 to 16 mph — it stays warm well into Sunday night.
Best Window To Be Outside
The whole day is workable, but morning is the sweet spot. Cooler temps and lighter winds make it ideal for a walk on the course — a golf push cart will save your legs on those longer layouts. Anglers should find a solid early window along the Meramec or Missouri River before the afternoon winds pick up. Check out outdoor gear deals if you need to stock up before heading out.
Cardinals vs. Royals at Busch Stadium
The St. Louis Cardinals host the Kansas City Royals today at Busch Stadium — and the weather delivers. Expect upper-80s to low-90s under mostly sunny skies at game time. It’s the Cardinals Boat Tote with Charm giveaway day, so arrive early and stay cool. Rep the Redbirds in a St. Louis Cardinals jersey or a St. Louis Cardinals fitted cap. Still need seats? Find tickets on StubHub before first pitch.
Rain and Storm Risk — Monday
Today carries nearly zero rain risk (just 2%), but Monday flips the script. The National Weather Service is forecasting showers and thunderstorms likely on Monday, with a 60% chance of precipitation and a high still near 89°F. The Weather Prediction Center flags a marginal risk of excessive rainfall near the Iowa/Missouri border, where multiple inches have already fallen — any slow-moving storm lines could bring brief heavy rain and localized flooding. Move Monday outdoor plans to the morning if possible and keep the umbrella within reach.
Tonight: Freddie Gibbs at The Factory
Looking for a cool way to end a hot Sunday? Freddie Gibbs brings The Last Rabbit Tour to The Factory tonight — a great indoor cap to the day. Get tickets on SeatGeek if you’re still looking. Later in the week, the MJ (Touring) show continues at the Fabulous Fox Theatre on May 19, with Qveen Herby also at The Pageant that same evening.
Dinner and Grilling
Tonight is textbook grilling weather. Fire up burgers, steaks, or grilled chicken with corn on the cob while the sun’s still up. Make sure your instant-read meat thermometer is ready so nothing comes off the grate under- or overdone, and give the grates a quick scrub with a grill brush and scraper set before lighting up. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered right to your door.
Next Few Days
Monday brings a 60% storm chance — plan outdoor activities early and monitor updates. The Cardinals are back home Tuesday, May 19, hosting the Pittsburgh Pirates, with another game May 20. Keep an eye on conditions as the active weather pattern continues across the region heading into next week.
