St. Louis kicks off Juneteenth with sunny skies and a high near 84°F — grab a hat and get outside, because this is one of the nicest weather days of the entire week.
Today’s Setup
A Canadian high-pressure system settled over the Midwest overnight, delivering near-calm winds (0 to 3 mph out of the northwest) and clear skies for most of the day. The National Weather Service flags patchy fog before 7 AM CT — especially in river valleys and low-lying areas near the Mississippi River — but it burns off quickly after sunrise. By mid-morning you’ll have wall-to-wall sunshine. Tonight turns mostly cloudy with a comfortable low near 66°F and a southeast wind around 3 mph.
Best Window To Be Outside
The whole day is your window. Forest Park, the Gateway Arch grounds, and neighborhood parks across the city will fill up with Juneteenth celebrations today — and the weather won’t give anyone a reason to stay home. Golfers, this is your day: winds under 3 mph, full sun, and temps in the low-to-mid 80s. Tee it up early and stay as long as you’d like.
Tonight’s concert scene is stacked. The MGK Lost Americana Tour stops at Hollywood Casino Amphitheater tonight (June 19), Ben Folds plays The Factory, and Stokley headlines The Pageant with throwback R&B vibes. All three shows should see dry, comfortable weather by showtime. Get tickets on SeatGeek or Find tickets on StubHub.
Grilling & Dinner Plans
With 84°F temps and near-calm air, tonight is textbook backyard grilling weather. Fire up burgers, steaks, or grilled chicken with corn on the cob — a fitting Juneteenth cookout spread. An instant-read meat thermometer takes the guesswork out of doneness, and a grill brush and scraper set keeps your grates ready for the rest of summer. Feeling ambitious this weekend?

Saturday: Great Afternoon, Storms After Midnight
Saturday tops near 87°F with mostly sunny skies after a brief early-morning shower risk between 7 and 8 AM CT. The afternoon looks excellent for the Santana & The Doobie Brothers - Oneness Tour 2026 at Hollywood Casino Amphitheater (June 20) — that’s an outdoor venue, and conditions should be comfortable through the evening. Grab a Santana t-shirt and enjoy the show. But the National Weather Service warns of showers and thunderstorms arriving after 1 AM CT, with widespread storms expected from late Saturday night through early Monday afternoon. Those storms are capable of locally heavy rainfall, per the NWS St. Louis office.
Cardinals at Busch Stadium — June 22
The St. Louis Cardinals host the Arizona Diamondbacks on Monday, June 22 at Busch Stadium. The active storm pattern could bring lingering rain into early Monday afternoon — check back as game day gets closer for a full tailgate outlook. In the meantime, rep the Redbirds with a St. Louis Cardinals jersey or St. Louis Cardinals fitted cap. Browse outdoor gear deals while you’re planning the pre-game spread.
