This morning, Monday, June 22, 2026, St. Louis woke up under a blanket of clouds and a cool start in the mid-60s. It will stay mostly cloudy through the day, with a high near 75°F and a north breeze around 7 to 10 mph. That cooler, post-front airmass is keeping things feeling noticeably fresher than what residents usually slog through in late June.
Afternoon Winds And Commute
With north winds holding steady around 7 to 10 mph, afternoon temperatures should top out only in the low to mid-70s, so the trip home will feel more like early spring than peak summer. Skies are expected to gradually thin and scatter later in the day, and the evening drive looks dry across the metro, with no rain expected to complicate the commute.
Fog Possible Tonight
Late tonight into early Tuesday morning, there is a small chance for river-valley or patchy fog, mainly south and east of the St. Louis metro. Recent rainfall combined with a settling surface high could allow fog to form where skies manage to clear. Forecast confidence is on the low side, around 20 percent, so it is more a heads-up than a guarantee. If you have early-morning plans Tuesday, give yourself extra time and be prepared for pockets of reduced visibility.
Midweek Storm Window
The big change arrives Wednesday into Wednesday night, when showers and thunderstorms become more likely across the region. According to the National Weather Service St. Louis, forecasters are calling for roughly a 30 to 60 percent chance of measurable rain in that window, with some storms capable of producing heavy downpours and gusty winds. The midweek risk was already on the radar in our earlier storm outlook, so it is a good idea to keep a backup plan ready for any outdoor events.
Late Week Warm Up
Temperatures are expected to run a bit below normal through Thursday, then trend warmer heading into the weekend, with highs climbing back into the 80s and peaking near 94°F by Sunday, June 28. Before you head out, keep an eye on hourly updates, since radar and local watches will be the best indicators of whether any storms could interfere with late-week or weekend plans.
