Intense heating during the afternoon of July 27th, coupled with the arrival of a pre-frontal trough over southern Indiana, led to the development of a broken line of severe thunderstorms that brought widespread wind damage across the Bluegrass Region of Kentucky during the evening hours. An outflow boundary from this initial line of storms later sparked scattered to numerous storms farther to the southwest, across central and south central Kentucky. Scattered wind damage and marginally severe hail continued well into the early morning hours.
