Tornado outbreak sequence of May 21–26, 2011
The tornado outbreak sequence of May 21–26, 2011 was one of the largest tornado outbreaks on record which affected the Midwestern and Southern regions of the United States. Most of the tornadoes developed in a corridor from Lake Superior southwest to central Texas; isolated tornadoes occurred in other areas. An especially destructive tornado destroyed one-third of Joplin, Missouri, resulting in 158 deaths and over 1,000 injuries. The Joplin tornado is the deadliest in the U.S. since April 9, 1947, when an intense tornado killed 181 in the Woodward, Oklahoma area. Tornado-related deaths also occurred in Arkansas, Kansas, Minnesota, and Oklahoma. Overall, the tornado outbreak resulted in 184 deaths, 6 of those non-tornadic, making it second only to the 2011 Super Outbreak as the deadliest since 1974, and the second costliest tornado outbreak in U.S. history behind that same April 2011 outbreak, with insured damage estimated at $4–7 billion.

Three people were killed and 133 reported injured. One of the fatalities was thrown by the tornado from her home to a backyard four or five houses away. Debris was found miles away. Over 4,000 buildings were damaged and 287 were destroyed. In terms of damage, it was the costliest tornado in American history to that date, with damages costing at least $250 million to $300 million (around $1.7 billion in 2015 dollars), and insurance costs estimated at up to $1.1 billion (in 1975). It was the third-costliest tornado, behind the Oklahoma City-area F5 tornado on May 3, 1999, and the Wichita Falls, Texas, tornadoes on April 10, 1979, until the Joplin, Missouri EF5 tornado on May 22, 2011. It is now currently the seventh-costliest tornado on record.
