A well-defined upper level shortwave trough shifted northeast across Missouri into the Ohio Valley, where it flattened out within a broader, strong southwesterly flow regime. The resultant mid level forcing was not very strong across the warm sector of the surface low. The weak surface low tracked northeast from Arkansas to West Virginia. A period of widespread rain during the late night and early morning hours generated local urban street flooding.
