| Brief Description: A large and destructive tornado accompanied with hail, up to softball size, ripped through eastern Logan County. An 88-year old farmer and his wife received minor injuries when the tornado flattened their home.

The farmer suffered a cracked vertebra and a lacerated hand. In all, five farmsteads were either damaged or destroyed. Several structures were destroyed, including three homes and numerous outbuildings. One modular home was lifted up and dropped 50 feet away from its foundation. Numerous pieces of farm equipment including, machinery, stock trailers and vehicles were damaged or destroyed. Three square miles of corn crops and several trees were destroyed.
