St. Louis is waking up to a grey, cool Friday with a high near 70°F and a 50% chance of afternoon rain showers — grab a packable rain jacket before you head out the door today.
Today’s Setup
A subtropical impulse is slowly nudging Gulf moisture northward, and the National Weather Service in St. Louis says showers become likely after 11 AM CT, aimed mainly along and south of I-44. Think the south city neighborhoods, Fenton, and Arnold — north St. Louis and St. Charles County may stay mostly dry. A light northeast wind around 7 mph keeps it feeling cool for late May. If you need to run errands near the Gateway Arch or Forest Park, the morning window is your friend.
Best Window To Be Outside
Get outside before 11 AM. After that, umbrella weather takes over through the afternoon. Tonight, showers taper off before 8 PM CT, then patchy fog develops overnight — give yourself extra drive time if you’re heading to Delmar Hall for the Nicotine Dolls show this evening.
Saturday: Soccer, Styx, and Storm Timing
Saturday opens with patchy fog before 8 AM, then partly sunny skies push the high near 82°F — a nice bounce back from today. The catch: the National Weather Service flags a 40–70% chance of showers and weak thunderstorms developing late Saturday into early Sunday.
St. Louis City SC hosts Austin FC at Energizer Park on Saturday, May 23 — an outdoor match with real late-day storm potential. Early afternoon tailgating should be fine; keep one eye on radar as the evening approaches. Gear up with a St. Louis City SC jersey or St. Louis City SC scarf before you go. Still need seats? Find tickets on StubHub or Get tickets on SeatGeek.
Styx with special guest Cheap Trick play the Ozarks Amphitheater on Saturday night — also outdoors, also in that storm window. A Styx hoodie is a smart call if storms hold off and temperatures drop. Tech N9ne & E-40: STRANGE Wid’ It Tour 2026 hits The Factory the same night (indoor — no weather worries). And MJ (Touring) lands at the Fabulous Fox Theatre Saturday — fully indoor and a great storm-safe option.
Rain and Fog Risk
No severe weather threat is in place for the St. Louis metro today. The Storm Prediction Center has no outlook for our area. The main hazards are reduced visibility from patchy fog tonight and Saturday morning, plus the late Saturday storm window. Nothing extreme — just be prepared.
What To Wear
Friday: light layers, packable rain jacket, waterproof shoes. Saturday morning: skip the jacket. Saturday evening: bring it back out. The fog Saturday morning means a cautious commute before 8 AM CT.
Rainy Day Dinner Idea
Today’s cool grey skies are built for a pot of chili or beef stew. Toss the ingredients into a programmable slow cooker before you leave this morning and come home to something warm. An enameled cast iron Dutch oven works just as well for a Sunday batch as storms roll through. Need supplies? You can order groceries on Amazon and have everything delivered straight to your door.
Next Few Days
Memorial Day carries a modest 20–40% shower chance, again mainly south of I-44, with near-normal temperatures. Tuesday onward brings slowly rising afternoon storm chances as Gulf moisture continues its push north.
