| Brief Description: A warm frontal boundary interacted with a complex of showers and thunderstorms to form a tornado on the southern flank of the precipitation. Touchdown was along Adamsville Road near Route 35. The roof was ripped off a home, 2 mobile homes were destroyed, along with a pole barn. The tornado then struck both rest areas on Route 35. The rest building on the north side of the highway was severely damaged. At least 2 tractor trailers were flipped over, while others parked in the lot, were damaged. Another mobile home near the rest stop was destroyed. Proceeding just east to Dewey Road, the tornado wiped a modular home off its foundation. A trailer was destroyed at the corner of Kerr and Viney Roads. Down Kerr Road, a home had its roof removed and a mobile home was moved off its foundation. On Fairview Road, another mobile home was damaged. What was amazing and fortunate, in just about all the cases, no one was home when the tornado struck. Three people were injured at the rest stop. | |||||||||||

| Brief Description: The tornado touched down to the southeast of Maysville, continuing east-southeast into Lewis County. The greatest damage occurred in the Heron Hill area in western Lewis County. Seventeen people were injured in Lewis County. 21 homes were destroyed, 10 homes sustained major damage and 17 homes received minor damage. Numerous barns, buildings and garages were also damaged or destroyed. The tornado appeared to skip across parts of Mason and Lewis Counties. Tornado damage ended four miles to the southeast of Vanceburg. A warm front stalled along the Ohio River, providing the focus for several clusters of thunderstorms to move across northern Kentucky during the early morning, lasting into the afternoon. Rainfall amounts from the thunderstorms generally ranged from three to five inches. The copious amounts of rain caused creeks and streams to rise out of their banks, and many roads were flooded and impassible. | |||||||||||
