Excessive Rainfall Thursday for the Southern Ohio River Valley
An area of low pressure just north of the Great Lakes will track eastward toward Maine onThursday into Friday with the cold front tracking southeastward. With southerly flow bringing ample moisture northward from the Gulf of Mexico, rain and thunderstorms will increase in coverage and intensity ahead of the front. Due to the slow movement of the front, any rain and thunderstorm activity will also move slowly, bringing the potential for heavy to excessive rainfall to the region. Rainfall amounts of 1-2 inches with locally higher amounts in excess of 3 inches are forecast. This will lead to the potential for flooding and runoff.
Major Cities in Region: Evansville, IN, Indianapolis, IN, Louisville, KY, Cincinnati, OH, Columbus, OH, Pittsburgh, PA
