St. Louis wakes up cool and clear Tuesday, with temperatures around 57°F across the metro early this morning. Things will warm quickly into the low 80s, with scattered showers and a few thunderstorms possible from late morning into the afternoon. The forecast calls for a high near 82°F and southwest winds of 5–12 mph, with gusts up to around 22 mph. Most of the day should stay dry, but a passing downpour could still turn a mid‑day commute into a wet one.
When Rain Might Affect Your Commute
Showers are most likely between about 10 a.m. and 4 p.m. Tuesday, with a slight chance earlier in the morning that ramps up toward midday. Coverage will be spotty, so one neighborhood might get a brief heavy shower while another a few blocks away stays dry. By tonight, skies should clear and temperatures will cool into the low 60s.
Severe Threat and Strong Gusts Wednesday
The bigger concern arrives Wednesday, when a sharper front and a surge of warmer air push temperatures into the low 90s and increase the wind. Forecasters say storms Wednesday afternoon and evening could become organized and severe, bringing damaging straight‑line winds, large hail, a few tornadoes, and locally heavy overnight rainfall. Even outside of storms, gusts of 40–45 mph are possible, according to the National Weather Service.
Plan Ahead
If you have outdoor plans Wednesday, it is worth moving them or lining up an indoor backup. Secure loose patio furniture and keep phones charged in case watches or warnings are issued. For background on how the pattern is setting up, see Monday's setup breakdown.
Temperatures and Outlook
Thursday should cool back into the low 80s with lingering shower chances, while Friday (Juneteenth) looks sunnier with highs in the mid‑80s. The weekend will be warm, with highs in the upper 80s and additional storm chances by Sunday into early next week. Keep an eye on updates as timing becomes clearer.
