Storm Alert | Locally heavy rainfall possible overnight, could cause flash flooding

Flash flooding may develop, especially south of the metro into early Thursday

ST. LOUIS — A large storm system continues to move across the middle part of the country. Severe storms moved through southwest Missouri early Wednesday and additional severe weather has pushed into Kentucky this evening. 

Showers and a few thunderstorms spread across the region early Wednesday morning dropping one to two inches of rain over southern parts of the area prompting a flash flood warning for parts of Phelps and Dent counties earlier Wednesday. A few isolated storms could be strong, but the greatest threat is expected to be from downpours which could cause areas of flash flooding. 

Most areas will see another half an inch to two inches of rain which will bring southern parts of Missouri and Illinois to a storm total of two to four inches of rainfall from this system once it winds down later Thursday.
