St. Louis woke up to mild, mostly clear skies Tuesday, with temperatures lounging in the mid‑60s. This afternoon still looks warm and pleasant, with highs in the low 80s, but there is a slight chance that a few quick‑hitting showers or an isolated thunderstorm pop up during peak heating between about 3 p.m. and 5 p.m. Most of the metro should stay dry, though any storm that does fire could dump heavy rain in a short burst.
This Afternoon: Timing And Where To Watch
Expect a high near 82°F Tuesday with light northeast winds around 2 to 7 mph, and just a small, low‑teens chance of showers between roughly 3 and 5 p.m. Rain chances tick up southeast of the city, where southeast Missouri and southwest Illinois are more likely to see scattered storms. These could produce brief, heavy downpours, but the overall setup is not favorable for organized severe weather, according to the National Weather Service Saint Louis.
Tonight: Spotty Showers Possible
After about 7 p.m., a chance of showers and thunderstorms returns, with lows sliding into the mid‑60s and southeast winds around 1 to 6 mph. Overnight precipitation probabilities rise into the 20 to 30 percent range, so the evening commute could run into brief slowdowns under heavier cells. Most of the activity should fade overnight, setting up a sunnier and warmer Wednesday for many neighborhoods.
Midweek Outlook: Drier Trend Into The Weekend
Wednesday is expected to be partly sunny with highs in the mid‑80s, as the pattern trends drier through the latter half of the week.

What This Means For Plans
Most outdoor plans should be in good shape, but it would not hurt to keep a light rain jacket nearby and be ready to shift evening activities inside if radar shows a pulse storm heading your way. Any brief heavy rain could lead to quick ponding on poorly drained streets, so avoid driving through standing water and plan for a little extra travel time if showers develop during the commute.
