St. Louis commuters could face wet roads this morning as thunderstorms spread across eastern Missouri, raising concerns for travel along I-70. Heavy downpours and patchy fog may reduce visibility during rush hour, prompting drivers to slow down and plan extra time.
According to the National Weather Service in St. Louis, scattered showers and thunderstorms will continue through Wednesday afternoon, with chances tapering off by evening. Rainfall could lead to ponding on low-lying streets, especially in the city and nearby suburbs. Winds remain light, but brief gusts may accompany stronger storms.
By Thursday, drier air will settle in as high pressure builds, bringing sunshine back to much of eastern Missouri and southwest Illinois. Highs will climb near 78°F on Thursday and 81°F on Friday, offering a calmer stretch of weather after the midweek storminess.
The return of sunshine will carry through the weekend. Temperatures will rise into the low 80s Saturday and Sunday, giving the St. Louis area one of its first extended runs of pleasant fall conditions. Nights will cool into the 50s and 60s, ideal for outdoor plans and early fall festivals.
This transition marks the last days of September with no major hazards expected into early next week. While it’s still too warm for a true winter preview, cooler evenings suggest a shift is coming soon.
