| Brief Description: A multiple vortex tornado tracked across the southern part of the county. The tornado damaged or destroyed 56 mobile homes and 27 single family homes. Several barns and sheds were destroyed and numerous trees were downed. No serious injuries or deaths occurred with this tornado. A low pressure system with an unusually strong mid and upper level jet streak was moving across the Great Lakes with an associated cold front moving across the upper Ohio valley. Thunderstorms developed across Indiana and moved into West-Central Ohio around mid-afternoon with a distinct bow echo causing wind damage from near to Lima to southeast of Columbus. On the southern edge of the first line of storms, a supercell developed over Central Indiana. This storm evolved into a bow echo and swept across the Dayton metro area causing extensive wind damage and a brief tornado in Greene county. Another supercell developed near Cincinnati and moved southeastward along the Ohio River. This storm produced the F3 tornado in Clermont county. | |||||||||||

| 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. | |||||||||||
