St. Louis weather today brings a chance of showers and thunderstorms through the afternoon, with a high near 82°F — time your outdoor plans around the storm windows and Wednesday is still very workable.
Today’s Setup
The National Weather Service is giving St. Louis a 30% chance of rain showers and storms through 5 PM CT, with light north winds of 1 to 5 mph. NWS forecasters note the storm activity is most likely focused along the I-70 corridor into Illinois, so your neighborhood may stay completely dry — but confidence in storm location is low, so keep radar close. One early heads-up: dense fog was developing across the Ozarks this morning. If you’re heading south on I-44, give yourself extra travel time until it burns off.
Storm Timing
The stormiest windows run 10 AM–1 PM CT and again 1–5 PM CT, with a brief rain chance even before 10 AM. Gateway Arch grounds, Forest Park, and Tower Grove Park should be fine in the morning, but afternoon plans outdoors are a gamble. Tonight clears to mostly cloudy with a low around 64°F and only an 8% rain chance — a comfortable evening once the day’s drama passes.
Best Window To Be Outside
Morning gets the green light. Mow the lawn, walk the dog in Soulard, or finish any outdoor errands before 10 AM CT. After 5 PM CT, skies should cooperate for a comfortable evening out. This is not a day to leave windows open at the office.
What To Wear Or Bring
Toss a packable rain jacket in your bag before you walk out the door — it weighs almost nothing and you’ll be grateful during a pop-up storm. Families on school pickup duty: a pair of kids rain boots will save you from the wet sock meltdown. Light layers work fine for the evening low of 64°F.

Killers of Kill Tony at The Factory (May 29) and Hadestown at the Fabulous Fox Theatre (May 29): Friday looks dry and pleasant at 80°F — great conditions for a night out on either side of downtown.
Rainy Day Comfort Food
A stormy afternoon is the perfect excuse to load up the slow cooker before noon and let dinner handle itself. Chili or beef stew practically makes itself in a programmable slow cooker, or go stovetop with an enameled cast iron Dutch oven for a thick soup that feeds the whole week. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Thursday clears out significantly — partly sunny with a high near 84°F and barely any rain chance. Friday dips slightly to 80°F with a 20% chance of rain returning. The National Weather Service says conditions trend drier through the weekend, which is great news for the Cardinals-Cubs series and outdoor Memorial Day weekend plans. Keep tabs on the St. Louis weather forecast for daily updates as the holiday weekend approaches.
