context_page_description: 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.
context_section_description: During the evening of May 24th, this narrow but violent EF4 tornado caused major damage in rural parts of Grady and McClain Counties at the same time another violent tornado from a separate supercell storm was devastating areas in and around Chickasha and Blanchard.
  The tornado touched down west of Bradley, causing EF0 to EF1 tree damage as it crossed State Highway 19 (SH-19). Continuing to the northeast, the tornado intensified further to EF3 strength as it passed through rural areas of Grady County, snapping and debarking numerous trees. An extensive swath of ground scouring began as the tornado crossed into McClain County. The tornado then reached EF4 strength as it crossed SH-76, leveling and sweeping away several well-built homes. Vehicles were thrown long distances and mangled almost beyond recognition nearby. The tornado weakened and narrowed as it crossed CR 410, with EF2 to EF3-strength damage occurring in that area. The tornado re-intensified to EF4 strength further to the northeast as it passed between Dibble and Washington. Numerous well-built homes were leveled in that area, and some were swept completely away. Unusual cycloidal debris impact scars were noted in open fields as well. One well-built home in this area with numerous anchor bolts was reduced to a bare slab, though a metal fence immediately next to the house remained standing and grass on the property was not scoured. Another home that was reduced to a bare slab in this area had anchor bolts spaced every two feet (well above the standard of anchoring required for an EF5 rating), though a closer inspection of the home site revealed that a large mobile home frame had smashed into the house during the tornado, and a jacuzzi found in the rubble behind the house was still in usable condition. Due to these contextual discrepancies, damage in this area was rated high-end EF4 rather than EF5. The tornado curved sharply to the north and weakened to EF3 strength as it continued north of Washington, though one final area of EF4 damage occurred southwest of Goldsby as a large, well-built home was completely swept away with only the slab remaining, and large metal storage tanks behind the house were tossed. This home was specifically engineered to be tornado resistant, though close inspection of the foundation revealed that some of the anchor bolt washers were missing, and the ones that were present were slightly too small, preventing a rating higher than EF4. Further to the north, minor EF0 damage occurred near David Jay Perry Airport before the tornado dissipated. Large amounts of debris from this tornado reportedly fell from the sky in Norman.
  Overall, the tornado was on the ground for 23 miles (37 km). 61 people were injured, though no fatalities occurred. Despite the presence of multiple well-built, anchor-bolted homes being swept completely away along the path, the tornado was not rated EF5 due to several contextual discrepancies and minor anchoring flaws. A high-end EF4 rating was applied as a result. Despite this, much like the Chickasha–Blanchard tornado, the EF4 rating is disputed, and the tornado is suspected by some to have been an EF5.
