Tornadoes


Late in the evening hours on the 15th into the early morning hours on the 16th, a single well-formed supercell thunderstorm tracked from southern IN through northern KY and eventually into southwestern and central OH during the heart of the overnight hours. This single storm exhibited strong rotation at various points along its track, eventually producing numerous, but rather short-lived, tornadoes during a 3-4 hour span. The most significant of these tornadoes was an EF2 which touched down in Ross County, Ohio near the town of South Salem.
