F1 tornado in Knox County, Kentucky

A tornado, 210 feet wide, briefly touched down just south of Hammond. It lifted, and touched down again near Hammond. Numerous trees were down and two trailers, two homes, and on garage were damaged.

On the afternoon of May 30th, a warm front was draped across eastern Kentucky. With extremely moist and unstable air, this boundary helped spark the beginning of a most unusual event for eastern Kentucky, and for that matter, for the country. Countless supercell thunderstorms developed along this boundary for hours on end, causing widespread tree damage and damage to structures. Flash flooding was also occurring with these storms which contained torrential rain. Unfortunately for eastern Kentucky, this was not the end to the severe weather or the flooding. Later in the night, mostly in the early hours of May 31st, a potent cold front burst through, bringing destruction to most if not all eastern Kentucky counties. Also, so much rain had fallen from the previous afternoon and evening, coupled with more heavy rain during the morning of May 31st, that widespread aerial flooding occurred. For some counties, as was the case for Estill and Powell Counties, the aerial flooding lasted for days. The cost of these storms totaled easily in the millions.
