St. Louis weather today (Saturday) means scattered showers and thunderstorms with a high near 84°F, and the National Weather Service has a flash flood watch in effect until 7 PM CT — get outdoor errands done early and keep a packable rain jacket within reach for the afternoon.
Today’s Setup
Overnight lows held near 72°F with a 51% chance of storms, and today’s high near 84°F comes with an 80% chance of showers and thunderstorms. The NWS St. Louis office says scattered storms continue through late afternoon before gradually shifting south this evening, with mostly light northwest wind around 3 to 8 mph. Ground across the metro is already saturated, so today’s rain will mostly run off fast rather than soak in.
Best Window To Be Outside
Morning is your best bet, before storm chances firm up into likely storms between 3 PM and 5 PM CT. Conditions ease tonight as activity slides south, and Sunday looks sunny with a high near 86°F and just a 4% rain chance — the better day for a walk near the Gateway Arch grounds or catching up on yard work.
Flash Flood & Storm Risk
The flash flood watch runs through 7 PM CT today. Forecasters note localized rainfall rates of 1-2 inches per hour are possible, and with soils already saturated, that means rapid rises on area streams and tributaries — avoid low-lying roads and creek crossings this afternoon. An isolated severe storm with damaging winds is also possible, mainly toward far southeast Missouri and southwest Illinois. Keep a battery backup phone charger topped off in case gusty storms knock out power.
Cardinals, Blues & Around Town This Weekend
The St. Louis Cardinals host the Atlanta Braves today at Busch Stadium for David Eckstein Bobblehead Night, with the series continuing Sunday. Given the afternoon storm risk, tailgaters should watch the radar and expect a possible rain delay before first pitch. Grab a St. Louis Cardinals jersey or St. Louis Cardinals fitted cap before heading down, or Find tickets on StubHub if you’re still deciding. Want to stay dry? The Blues’ Round 3 Home Game 3 at Enterprise Center is indoors tonight, and Jon Anderson plays The Factory this evening. Looking ahead, Elmiene brings the Sounds for Someone Tour to Delmar Hall on Sunday — Get tickets on SeatGeek if that fits your plans.
What To Wear, Tonight’s Dinner & Next Few Days
A compact travel umbrella beats sandals today, and it’s a good night to stay in. A pot of chili or beef stew in a programmable slow cooker, or simmered low in an enameled cast iron Dutch oven, fits the soggy evening perfectly. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door. Sunday turns dry and sunny near 86°F, and the National Weather Service expects mild, mainly dry conditions into early next week — a good stretch to check out outdoor gear deals and get back outside around St. Louis.
