St. Louis is waking up to a raw, soggy Tuesday on May 5, 2026, with cloudy skies, damp air and temperatures stuck in the upper 50s this morning at Spirit of St. Louis Airport. Showers and thunderstorms are expected to hang around through tonight, with a daytime high only near 57°F and north winds of 5 to 12 mph. Drivers should be ready for reduced visibility and brief ponding where heavier showers roll through.
What To Expect Today
On-and-off rain with embedded thunderstorms will stay in the picture across the metro through the evening, especially late afternoon into early evening when activity is most likely. According to the National Weather Service, severe storms and widespread flooding are not anticipated, but heavier pockets of rain could still knock down visibility and cause quick ponding on roads.
Afternoon Commute
The wettest stretch is expected from mid-afternoon into tonight, when hourly guidance bumps rain chances into the 60–80% range and the strongest cells are most favored. Our May 4 update dug into the incoming evening round and kept the travel concern on the table, recommending extra time for drivers and transit riders alike; see our evening commute storms coverage for background.
Looking Ahead
Cool air will linger through Thursday, with highs holding in the upper 50s to around 60°F. Late in the week, a push of warmer air noses in from the south, sending highs into the 76–79°F range by Saturday. Another front could bring a fresh round of showers and thunderstorms on Sunday, so outdoor plans late in the weekend may need a backup option.
Quick Tips
Keep the rain jacket and umbrella in rotation, build extra time into your commute and avoid driving through standing water. No watches or warnings are in effect for the metro right now, but that can always change, so check the National Weather Service or local alerts before you head out.
