During the late afternoon and evening hours on May 21, widespread strong to severe thunderstorms erupted across eastern Kentucky. The storms formed in a warm and moist air mass ahead of an approaching cold front that was moving out of the central and southern Plains. The storms produced damaging wind gusts along outflow boundaries that moved along the surface out ahead of the storms themselves.
