ST. LOUIS, MO (KTVI) – Strong to severe thunderstorms brought large hail and pouring rain to much of the St. Louis region Tuesday morning. As the storms moved in, viewers reported golf ball sized hail around Warrenton and Augusta. Then the hail became extensive, blanketing the ground in quarter to half-dollar size ice pellets in west St. Louis County.
The torrential rains fell fast and heavy, dropping one to two inches of rain in less than 30 minutes in many areas. Sewer systems quickly became overwhelmed, leaving standing water on roads, and small streams and creeks filled up quickly, causing flash flooding that damaged yards and small dams.
The hail and rain snarled traffic in the area. At one point a semi tractor trailer jackknifed on I-44 near the Jamieson exit. Vehicles were only able to get by on the shoulder of the highway.
The forecast for St. Louis doesn’t improve for several days. Scattered thunderstorms remain in the forecast through Thursday, with some potentially becoming severe.
