On April 10–12, 1965, a devastating severe weather event, known as the Palm Sunday tornado outbreak, affected the Midwestern and Southeastern United States. The outbreak produced at least 55 confirmed tornadoes, 18 of which were retrospectively considered to be violent on the Fujita scale. Only the 1974 Super Outbreak featured a larger number of F4–F5 tornadoes. At least three of the 18 F4s recorded during the 1965 outbreak—near Dunlap, Indiana, Lebanon–Sheridan, Indiana, and Pittsfield–Strongsville, Ohio, respectively—may have reached F5-level intensity. The outbreak was one of three major tornado outbreaks to coincide with the Christian holy day Palm Sunday, the others having occurred in 1920 and 1994.
