St. Louis, Missouri – Spring weather brings an unsettled forecast for St. Louis, with severe thunderstorms, flooding risks, and cooler temperatures expected to hit throughout the week. Monday looks to be a day of active weather, as heavy rain, gusty winds, and a chance of severe thunderstorms take over the region. The National Weather Service has issued a Flood Watch that will remain in effect until 1:00 AM Monday, signaling potential flooding issues, especially in low-lying areas.
According to the NWS, rain will begin Sunday evening, continuing through the night into Monday morning. Flash flooding is possible due to the high volume of rain. Areas south of St. Louis could see localized flooding on roadways, particularly along major routes like Interstate 55. Motorists should prepare for hazardous conditions, especially after sunset. For those planning to drive, use caution on I-44 and Route 40, as wet conditions could lead to slick spots and reduced visibility.
As the storm system presses forward, severe thunderstorms will roll through Monday night, bringing gusty winds and the possibility of large hail. The severe weather alert remains in effect through early Tuesday morning, when conditions should calm down slightly. Be prepared for cooler temperatures as high winds, along with gusts up to 30 mph, will continue through the day.
