St. Louis, MO – A strong cold front moving through eastern Missouri on Sunday could bring showers and thunderstorms, with a limited risk of damaging winds during the afternoon and evening hours.
According to the National Weather Service in St. Louis, showers are expected to move through the region Sunday afternoon as the front approaches. Forecasters estimate a 50% chance that the atmosphere will become unstable enough to support thunderstorms along the front.
While most storms are expected to remain below severe levels, the Weather Service cautioned that if thunderstorms develop, a few could become strong, with a 70% chance that any stronger storms could produce damaging wind gusts. A brief tornado cannot be ruled out, though the overall severe weather risk remains low.
The Storm Prediction Center has placed the St. Louis region under a Marginal Risk (Level 1 of 5) for severe thunderstorms. This category indicates isolated severe storms are possible but not expected to be widespread.
Storms are expected to be fast-moving, which should limit rainfall totals and reduce the risk of flooding. However, sudden gusty winds could still pose hazards to motorists, outdoor activities, and unsecured objects.
Residents are encouraged to remain weather-aware Sunday afternoon, especially if spending time outdoors. Loose items should be secured, and those traveling should be prepared for sudden changes in weather conditions as storms pass through.
Behind the cold front, much colder air will move into the region, marking a sharp shift back to winter-like temperatures early next week. Additional forecast updates may be issued as confidence increases in storm coverage and intensity.
The National Weather Service advises monitoring trusted weather sources for the latest updates and potential statements as the front approaches.
