St. Louis wakes up Monday, March 2, to a cool, gloomy start, with thick clouds locked in across the metro and temperatures parked in the low 40s. Light drizzle is expected on and off through the day, keeping both the morning and afternoon commutes damp and holding the high near 43°F.
Afternoon Drizzle And A Cool High
Drizzle is most likely before 5 p.m. Monday, March 2, with a roughly 60% chance of precipitation and northeast winds around 7 to 10 mph. Expect a solid blanket of clouds through the afternoon, with pockets of light drizzle rather than any steady, soaking rain, and a high near 43°F. According to the National Weather Service St. Louis, conditions should stay damp but not widespread, and there are currently no watches or warnings in effect for the area.
Tonight Into Tuesday
After sunset Monday, patchy fog could develop between about 10 p.m. and midnight, followed by increasing showers and thunderstorms overnight into Tuesday, March 3. The combination of fog and early showers may cut visibility for late-night drivers before heavier activity moves in.

Midweek Warm-Up And Heavy Rain Potential
The forecast discussion from the National Weather Service St. Louis points to a moist, active setup through Wednesday and Thursday, with the potential for training storms and periods of heavy rain that could lead to localized flooding where totals stack up. Temperatures climb into the upper 60s by Wednesday, and a strong warm sector could push readings toward the upper 70s by Friday, March 6, making the back half of the week feel a lot warmer than Monday’s chill.
Commutes And What To Do
From Tuesday through Thursday, plan on a soggy stretch of commuting. Patchy fog tonight may briefly cut visibility, and downpours during the day could slow travel. Metro Transit is urging riders to build in extra time and check the latest system updates before heading out, with alerts and service notices available from Metro Transit. If you have outdoor plans later in the week, you may want a backup indoor option and a close watch on the forecast for any flood or thunderstorm warnings.
