St. Louis is waking up to a stormy Saturday — showers and thunderstorms are likely through mid-morning, so hold off on outdoor plans until after noon and keep an eye on radar before heading to Busch Stadium or anywhere along the riverfront.

Today’s Setup

The National Weather Service has a 60% precipitation chance for today, with the heaviest activity expected between 8 and 11 AM CT. The AFD out of the St. Louis NWS office warns the strongest storms this morning could produce hail up to 1 inch and damaging wind gusts — not a morning to be caught outside unprepared. High reaches near 84°F with south winds 6 to 9 mph and mostly cloudy skies throughout.

Best Window To Be Outside

Storm coverage is forecast to gradually fade through the afternoon, dropping to around a 30% chance by midday and beyond. If you need to run errands or get kids to activities, target after 1 PM CT. Saturday night looks much nicer — partly cloudy, low around 66°F, with just a 20% chance of leftover storms before 8 PM CT.

Storm Risk and Safety

The morning window is the one to watch. Hail up to 1 inch and gusty wind are the primary threats. Keep a waterproof document bag in your car if you’re heading out with important papers, and do not wait out storms under trees near Forest Park or along the Arch grounds.

Cardinals, Pointfest, and Today’s Big Events

The St. Louis Cardinals host the Kansas City Royals at Busch Stadium today — storm timing makes this a tricky morning for early tailgaters. Check our Busch Stadium gameday weather guide for full game-day details. Dress in layers and grab your St. Louis Cardinals jersey and St. Louis Cardinals fitted cap, but toss in a rain shell too.

Outdoor fans heading to POINTFEST at Hollywood Casino Amphitheater today should know morning storms could affect the schedule — check the venue’s weather policy before you go. Get tickets on SeatGeek if you’re still on the fence. For indoor options, Ali Wong performs at Stifel Theatre and Zoltan Kaszas brings comedy to The Pageant tonight — both solid dry-weather backups.

Sunday Rebound

Sunday is the reward. Sunny skies and a high near 91°F make it a near-perfect day for the Cardinals’ second game against the Royals. South winds 8 to 16 mph with gusts up to 28 mph will keep it feeling fresh rather than stifling. Sunday evening, Freddie Gibbs brings The Last Rabbit Tour to The Factory — grab a Freddie Gibbs t-shirt to rep the show. Find tickets on StubHub if you haven’t locked in seats yet.

Rainy Day Comfort Food

A stormy Saturday is exactly when a programmable slow cooker earns its counter space — load it up with chili or beef stew before the morning storms hit and dinner handles itself. An enameled cast iron Dutch oven works beautifully for a big pot of soup on the stovetop too. Need supplies? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.

Next Few Days

Sunday’s sunshine is gorgeous but brief. The NWS warns of additional thunderstorm chances early next week, with a more widespread severe weather threat possible Monday night into Tuesday along a slow-moving cold front. Keep your weather app updated — this pattern has teeth heading into the workweek.
