St. Louis is starting Tuesday with wall-to-wall sunshine and a high near 81°F — low humidity, a light northeast breeze of 6 to 13 mph, and essentially zero chance of rain. Get outside and enjoy it.

Today’s Setup

A sprawling high pressure system is drifting from the Great Lakes toward the East Coast, dragging drier air into St. Louis behind a back door cold front, according to the National Weather Service. That low dew point is why the air feels so clean today. Strong June sun will push afternoon highs near 81°F. Tonight, good radiational cooling drops temperatures to around 57°F under mostly clear skies — great sleeping weather with the windows open.

Best Time To Be Outside

Both Tuesday and Wednesday are the pick of the week. Wednesday stays sunny with a high near 82°F and lighter winds at 3 to 8 mph. Thursday warms to near 87°F as south winds return and humidity begins to build — still dry, but you’ll feel the difference.

Cardinals game weather: The St. Louis Cardinals host the Texas Rangers at Busch Stadium on June 2 under clear skies, with temps falling through the 70s by first pitch. Wednesday’s game looks just as beautiful. Gear up with a St. Louis Cardinals jersey or a St. Louis Cardinals fitted cap and head down to the Arch District. Find tickets on StubHub if you need seats.

Tonight at The Pageant: Tash Sultana plays on June 2 — clear skies and mild temps make for a perfect evening out. Grab a Tash Sultana t-shirt and Get tickets on SeatGeek.

Looking ahead to Friday, June 5: HARDY brings THE COUNTRY! COUNTRY! TOUR! to Hollywood Casino Amphitheater. Rain chances increase by then, so a HARDY hoodie or HARDY hat is solid insurance against a spotty evening. Get tickets on SeatGeek now while you can.

Rain And Wind Risk

None today. Winds are light at 6 to 13 mph from the northeast — comfortable, not disruptive. Worth securing your outdoor furniture covers overnight so nothing shifts in the light breeze.

What To Wear

Shorts and a t-shirt by noon. A hat and sunscreen are your real must-haves — St. Louis in early June has intense sun even when temperatures feel manageable.

Grill Night

This is textbook backyard cookout weather. Fire up the grill for burgers, steaks, or grilled chicken with corn on the cob. Feeling ambitious? Our smoke tri-tip guide breaks down a technique that rivals brisket for about $10. An instant-read meat thermometer keeps everything perfectly done, and a grill brush and scraper set is worth pulling out before the first cook of the season. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.

Next Few Days

Wednesday: sunny, near 82°F. Thursday: sunny and warmer near 87°F, humidity on the rise. Friday through the weekend: the National Weather Service forecasts increasing chances for showers and thunderstorms as a short wave trough sweeps in from the Plains — so enjoy this stretch now. Stay current with the St. Louis weather forecast and check outdoor gear deals while the sun lasts.
