List of Ohio tornadoes

Tornadoes in the state of Ohio are relatively uncommon, with roughly 16 tornadoes touching down every year since 1804, the year with the first recorded event in the state.

[3] Ohio's climate is relatively mild, and is only ideal for the formation of tornadoes during certain times of the year, especially February and March.

Warm air from the Southern United States can reach up into the Ohio Valley, resulting in tornadic storms.

Ohio's proximity to Lake Erie also results in cold air moving toward the Ohio Valley, creating the "hot-cold" effect seen in the traditional Tornado Alley.

[4] Ohio has been a part of multiple large tornado outbreaks, the most notable being the 1974 Super Outbreak.
