St. Louis, Mo. – Missouri residents could see storms develop late Wednesday as a cold front sweeps across the state, setting the stage for a cooler stretch of weather to close out the week. Highs will slide from the upper 80s into the 60s by Thursday, giving the region an early taste of fall.
According to the National Weather Service in St. Louis, scattered showers may linger through midweek, with the strongest chance of widespread rain and thunderstorms arriving late Wednesday afternoon into the night. Forecasters say central and southeast Missouri may see the earliest showers, while heavier downpours could develop near St. Louis during the evening commute.
Labor Day will bring partly cloudy skies and highs in the low 80s, while Tuesday stays mostly sunny with just an isolated shower in southeast Missouri. By Wednesday, clouds will thicken with widespread rain chances across the metro, prompting drivers to allow extra travel time for wet roads.
Behind the front, cooler and drier air arrives Thursday with highs only in the upper 60s. Nights late this week could dip into the 40s in some rural areas, a sharp contrast to the humid start of September.
Residents are urged to keep rain gear handy through midweek and monitor updates as storm chances increase Wednesday evening.
