St. Louis is starting Sunday, May 24 under a 40% chance of showers and thunderstorms — grab a packable rain jacket before you head out the door, because storms should clear by early afternoon and give way to a partly sunny high near 82°F.

Today’s Setup

The National Weather Service says lingering overnight convection is still pushing east across the metro this morning, with rain showers possible before 7 AM CT and the best chance of showers and thunderstorms running from 7 AM through 1 PM CT. After a weak cold front clears the area, conditions improve steadily through the afternoon. Forecasters also note patchy fog is possible near sunrise in some spots — particularly in low-lying areas near the Mississippi River bottoms — with visibility potentially dropping near a quarter mile before burning off.

Tonight looks quiet and comfortable: partly cloudy with a low around 61°F and just a 3% rain chance. Crack the windows.

Best Window To Be Outside

Once we’re past 1 PM CT today, most of the St. Louis metro — from Forest Park to Soulard to the Arch grounds — should be dry. Save the yard work, the bike ride along the Riverfront Trail, or the afternoon grilling for then. The real payoff comes Memorial Day Monday: mostly sunny skies, a high near 84°F, and a 3% chance of rain. Light east winds at 2-8 mph round out what should be one of the nicest Memorial Day holiday windows St. Louis has seen in years.

What To Wear Or Bring

This morning, your packable rain jacket earns its spot. Winds are light (2-8 mph from the north), so it won’t feel raw — just damp. By afternoon, a t-shirt and sunglasses do the job.

For Memorial Day, it’s full cookout mode. Fire up the portable propane grill and load the hard cooler 52 quart before guests arrive. If you’re squeezing in a round of golf before the backyard party, the Callaway Big Bertha Fairway Wood is just $150 right now — conditions Monday are textbook.

Events Around Town

Tonight at the Fabulous Fox Theatre, the MJ (Touring) show is on — weather should be clearing by showtime, but have that jacket for the walk in. The Mountain Goats are also at Delmar Hall tonight.

Looking ahead to May 29, the St. Louis Cardinals host the Cubs at Busch Stadium, capped off with a Jordan Davis postgame concert — a big night on Broadway. Grab your Official team gear on Fanatics before the series, and Find tickets on StubHub if you still need seats. Keep an eye on the forecast; the National Weather Service flags multiple rounds of showers and storms from Tuesday through Friday with limited day-to-day confidence.

Also May 29: the St. Louis Battlehawks take on the Dallas Renegades at The Dome at America’s Center — indoors, so no weather concern there.

On May 30, Les Claypool brings Claypool Gold to The Factory. Rep the show ahead of time with a Les Claypool t-shirt or Les Claypool hat, and Get tickets on SeatGeek before they sell out.

Rainy Day Dinner Idea

Today’s stormy morning was made for the slow cooker. Set your programmable slow cooker going with a batch of chili or beef stew before the rain hits, or use your enameled cast iron Dutch oven for a pot of soup that simmers all afternoon. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.

Next Few Days

Memorial Day (Monday): mostly sunny, 84°F, near-perfect — enjoy every minute of it. Tuesday through Friday, multiple rounds of showers and weak thunderstorms are expected, per the National Weather Service, with limited confidence on exact daily timing and coverage. Flexibility is your friend for any mid-week outdoor plans. Check back daily as confidence improves heading into the work week.
