St. Louis is opening the week with a gem — sunny skies, a high near 79°F, and a gentle northwest breeze of just 2 to 6 mph make this one of the nicest June Mondays we could ask for. Get outside today, because showers and storms are waiting in the wings starting Tuesday.
Today’s Setup
The National Weather Service is forecasting full sunshine through the evening, with a cool overnight low around 59°F. With that northwest flow keeping humidity in check, Forest Park, Tower Grove Park, and the Riverfront Trail will all feel genuinely comfortable this afternoon. No rain, no heat index concerns — just a clean summer day.
Best Window to Be Outside
Any hour works today. Morning is cooler — ideal for a walk, run, or a round of golf. Afternoon delivers peak sunshine. With winds barely nudging 2 to 6 mph, anything you set up outdoors stays put without a fight.
Cardinals at Busch Stadium: Three-Game Series
The St. Louis Cardinals host the San Diego Padres all week at Busch Stadium, and today’s game (June 15) is the weather winner of the series: sunny and near 79°F with barely a breeze. Pack your St. Louis Cardinals jersey and St. Louis Cardinals fitted cap — short sleeves are the call. Tuesday (June 16) carries a 40% chance of afternoon and evening storms, and the National Weather Service flags Wednesday as the highest-risk game of the homestand, with possible severe thunderstorms by evening. Check our Cardinals vs. Padres gameday weather for the full breakdown. If you still need seats, Find tickets on StubHub or Get tickets on SeatGeek.
Storm Risk Builds Tuesday Through Thursday
Per the National Weather Service in St. Louis, a cold front will push through Tuesday with showers and a thunderstorm or two possible from around 10 AM CT onward, with southwest winds gusting to 21 mph. Wednesday brings above-average temperatures and the most active storm setup of the week — some thunderstorms could reach severe limits Wednesday afternoon and evening. Before Tuesday afternoon, bring in lighter patio items or grab outdoor furniture covers. A pop-up canopy tent with weights is worth having anchored if you’re hosting anything outdoors this week.
Grill Tonight
This evening is built for the backyard. Fire up burgers, steaks, or grilled chicken with corn on the cob while skies are clear and temperatures are pleasant. An instant-read meat thermometer keeps doneness dialed in, and a grill brush and scraper set makes cleanup easy between rounds. Feeling ambitious? Our guide to Pork Loin Under $1/lb walks you through how to smoke one low and slow. Need supplies? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Events This Week
Shakey Graves plays The Pageant on Tuesday, June 16 — the venue is indoors, but build in extra drive time if afternoon storms pop before showtime.

Next Few Days
Tuesday: Partly sunny, near 82°F, 40% storm chance — keep an umbrella handy from late morning on. Wednesday: Above-average warmth with the highest storm risk of the week; severe weather possible by evening. Thursday: Additional storm chances linger before conditions gradually improve.
