St. Louis is in for a split-personality Sunday — partly sunny skies and a high near 84°F this afternoon, but an 80% chance of showers and thunderstorms tonight means you’ll want to plan carefully. If you have outdoor plans, go early and stay weather-aware for the evening.

Today’s Setup

Morning fog has cleared and the day looks decent across the metro — from Forest Park and the Arch grounds to Soulard and South City. The National Weather Service notes just a 20% chance of scattered showers and thunderstorms after 11 AM CT, with a gentle southeast breeze around 6 mph. Afternoon conditions are fine for a walk, a round at a local course, or patio time. The bigger story is what fires up after sunset. Check the St. Louis weather forecast for live updates as storms approach.

Cardinals at Busch Stadium

The St. Louis Cardinals host the Chicago Cubs today at Busch Stadium, and first-pitch conditions should be comfortable — mid-80s and partly sunny. The concern is the late innings and beyond. NWS forecasters warn that multiple rounds of storms are possible tonight, with likely thunderstorms before 10 PM CT carrying the potential for large hail and damaging winds. Know where the covered concourses are and keep your phone charged. Rock a St. Louis Cardinals jersey and a St. Louis Cardinals fitted cap — just maybe tuck an umbrella in the bag. Still need seats? Get tickets on SeatGeek or Find tickets on StubHub. You can also track Busch Stadium conditions on our Cardinals gameday weather page.

Storm Risk Tonight

The National Weather Service Area Forecast Discussion explains that weak steering currents today will make storm timing hard to pin down precisely, but two rounds are possible: one developing this afternoon into early evening, and another batch pushing through overnight. Expect likely thunderstorms before 10 PM CT, then a diminished but continued chance between 10 PM and 2 AM CT. Low drops to 66°F. If you’d rather avoid the risk entirely, the Hadestown touring production is at the Fabulous Fox Theatre tonight — a beautiful indoor option.

For storm prep, it’s worth having backup power on hand. The DARAN 288Wh Power Station Just $90 for Prime Members is a solid grab heading into an active weather stretch.

Monday and the Week Ahead

Monday brings another 50% storm chance before 2 PM CT with a high near 85°F — keep that in mind for the Cardinals vs. Texas Rangers opener at Busch Stadium. If you’re going, watch the morning radar. The good news: dry weather is forecast Tuesday through Thursday with near-normal temperatures. That’s your window for yard projects, grilling, or anything that got pushed by this weekend’s storms.

Tash Sultana plays The Pageant on Tuesday, June 2 — timing couldn’t be better as skies clear out. Grab a Tash Sultana t-shirt or a Tash Sultana hoodie and make a night of it. Check outdoor gear deals if you need anything for the week ahead.

Rainy Day Dinner

Tonight is made for comfort food. Load up a programmable slow cooker with chili or beef stew before the game — dinner handles itself while you’re downtown. An enameled cast iron Dutch oven is equally perfect for a big pot of soup on the stovetop when you get home. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.

Bottom line: Enjoy Sunday afternoon’s sunshine, but plan around a stormy evening. Storms could be strong before 10 PM CT. Things improve significantly Tuesday through Thursday.
