St. Louis is in for a gorgeous Thursday — sunny skies and a high near 76°F make this the best day of the week, so get outside before a stormier Friday takes over.
Today’s Setup
A surface high moving east is delivering mild, refreshingly dry air with a light southeast breeze of 1 to 8 mph. The National Weather Service confirms moisture doesn’t return until late tonight, keeping the entire daytime window completely clear. The Gateway Arch grounds, Forest Park, and the Missouri Botanical Garden are all looking ideal this afternoon. For the St. Louis weather forecast through the weekend, conditions get muggier fast — today is the outlier in a good way.
One heads-up for allergy sufferers: sunny days with light winds are prime pollen-dispersal conditions. Tuck an allergy relief nasal spray in your bag before heading out.
Best Window To Be Outside
All of Thursday is yours. Yard work, a round of golf, a walk along the Mississippi riverfront — the mid-70s and low humidity make every outdoor activity comfortable. Check out our outdoor gear deals if you’re gearing up for summer activities while the weather cooperates.
Tonight: Storm Timing
Pay attention once the sun sets. The National Weather Service expects showers and thunderstorms to develop mainly across northern Missouri around midnight CT, then push into the St. Louis metro during the pre-dawn hours Friday. These storms will be elevated in nature — the overall severe weather threat is low, but stronger cells could produce marginally severe hail or a localized downburst. Precipitation chances tonight climb to around 40%.
Events This Week
Friday night (May 15), Kid Rock’s Freedom 250 Tour takes the stage at Hollywood Casino Amphitheater. Morning storms should clear well before showtime, leaving a warm, humid evening. Dress comfortably and grab a Kid Rock t-shirt or Kid Rock hoodie for the show. Find tickets on StubHub.
Also Friday, don’t sleep on the Dayseeker: The Pale Moonlight Tour at The Pageant on May 15 — an indoor show, so no weather worries there.
The St. Louis Cardinals host the Kansas City Royals at Busch Stadium on May 16 and May 17 — expect warm, muggy mid-80s with storm chances Saturday. Grab your St. Louis Cardinals jersey and a St. Louis Cardinals fitted cap before heading downtown. Get tickets on SeatGeek.
Saturday also brings POINTFEST at Hollywood Casino Amphitheater on May 16 — an outdoor festival in increasingly humid air with storm potential. Check back for updates as that forecast firms up.
Grill It Tonight
Today’s weather is practically begging you to fire up the propane gas grill. Burgers, steaks, or grilled chicken with corn on the cob are all perfect for a 76°F evening. Use an instant-read meat thermometer to nail doneness every time, and keep a grill brush and scraper set handy for cleanup. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Friday warms to near 83°F with a 60% storm chance, mainly before 10 AM CT, then mostly sunny by afternoon — south winds could gust to 23 mph. Friday Night stays muggy near 66°F with a 30% storm chance after 1 AM CT. Warm, humid conditions with daily storm rounds continue through the weekend. The National Weather Service is already flagging a more focused severe weather threat early next week as a cold front arrives Monday or Tuesday — that one warrants closer attention.
