The May 1960 tornado outbreak sequence[nb 1][nb 2] was a large tornado outbreak sequence that affected the southeast High Plains, the southern Ozarks, and other parts of the Midwestern and Southern United States on May 4–6, 1960. The severe-weather event produced at least 71 confirmed tornadoes, including five violent tornadoes in the U.S. state of Oklahoma. Major tornado activity began on the afternoon of May 4, with strong tornadoes affecting the Red River Valley and the Dallas-Fort Worth Metroplex. Two F4 tornadoes struck parts of south Oklahoma, causing significant damage to the Konawa and Soper areas. In all, at least 22 tornadoes formed between the early afternoon and late evening hours, with two more tornadoes forming early on May 5, shortly after midnight local time. A much more significant tornado outbreak began on the afternoon of May 5 and continued overnight, spreading from eastern Oklahoma into portions of south Missouri and Central Arkansas. At least 35 tornadoes developed between 6:00 a.m. CST on May 5–6, including a long-tracked F5 that struck rural areas in Northeastern Oklahoma and killed five people. Two other F4 tornadoes killed 21 people in and near Sequoyah County in the eastern portion of the state. Other strong tornadoes affected the Little Rock metropolitan area early on May 6 in Arkansas. In all, the tornado outbreak sequence killed 33 people and injured 302.

Notes
- ^ An outbreak is generally defined as a group of at least six tornadoes (the number sometimes varies slightly according to local climatology) with no more than a six-hour gap between individual tornadoes. An outbreak sequence, prior to (after) modern records that began in 1950, is defined as, at most, two (one) consecutive days without at least one significant (F2 or stronger) tornado.[1]
- ^ All damage totals are in 1960 United States dollars unless otherwise noted.
