St. Louis woke up to clear skies and a brisk 41°F, and Monday is shaping up to be a mostly sunny day with a high around 70°F. Light southeast breezes will keep things comfortable for park time, patio lunches and the commute home. That calm will not last; the week turns noticeably warmer and more humid before storms roll in late in the week.
This Morning And Monday
Sunshine should hold through the day with highs near 70°F and light southeast winds of about 2–7 mph, making for easygoing outdoor plans. The National Weather Service is calling for a dry start to the week with little chance of rain through Monday, so park outings and after-work activities look good to go. Keep the sunglasses nearby, since UV levels will be higher than in recent days.
Midweek Heat And Gusts
By Tuesday, temperatures start climbing and stay warm through Thursday, with highs pushing into the low 80s as more humid air returns. Southwest winds pick up in the middle of the week, and gusts could reach around 24 mph on Tuesday, which means noticeably breezier afternoons. If you are planning midday outdoor work or sports, drink plenty of water and be ready for the occasional shove from a gusty wind.
Late-Week Storms
Showers and thunderstorms become more likely late Thursday night into Friday. The highest chance comes overnight into Friday morning, with additional storms possibly redeveloping Friday afternoon and evening. Forecasters say much of the region could see a soaking rain and that some storms may be gusty or briefly strong, although the exact timing and coverage could still shift. For more on how this setup is evolving, see warm Thursday before storms crash in Friday.
What To Do Now
If you have outdoor events planned for late Thursday or Friday, start thinking about a dry backup spot and avoid driving through standing water once the rain arrives. Keep weather alerts turned on and check updates from the National Weather Service for any watches or warnings as the system approaches. Even small timing changes could shuffle evening plans, so give the forecast another look before heading out.
