Clusters of thunderstorms intensified across western Kentucky during the afternoon. The storms then propagated slowly southeastward through a moderately unstable environment, with mixed-layer capes around 2000 j/kg. Effective bulk wind shear values of 30 to 40 knots were favorable for organized convection. Damaging wind gusts accompanied the strongest storms, and some isolated large hail was reported. The storms formed along and ahead of a weakening convective outflow boundary as it moved southeast across the Lower Ohio Valley. Some places were in the path of two or three clusters of storms. The resulting heavy rainfall totals over moist ground resulted in isolated flash flooding.
