It would first produce an F5 tornado that would hit Blackwell, Oklahoma, before going on to produce another F5 that would devastate the town of Udall, Kansas.
Tornado summary
About 30 minutes after producing the Blackwell tornado, the same supercell produced this large and violent and long-tracked tornado just east of the first tornado track near the Kansas/Oklahoma border. It proceeded northward across Sumner and Cowley Counties. The town of Udall was especially hard hit with F5 damage that included the disintegration of numerous structures and homes all across the town. Even the town's water tower was toppled. The funnel, about 1300 yd m out wide, hit Udall at around 10:30 p.m. CDT. Half of the town's population was killed or injured. Numerous homes and businesses were destroyed, many of which were swept away, including a 30-by-40 foot concrete block building that was obliterated, with the foundation left mostly bare of any debris. Vehicles were thrown hundreds of yards and mangled beyond recognition, including a pickup truck that was wrapped around a tree and stripped of everything but its frame and tires.Grazulis Thomas P Significant Tornadoes 1680-1991 July 1993 The Tornado Project of Environmental Films 1-879362-03-1 St. Johnsbury, VT The Udall public school building sustained major damage, with beams snapped and blown away.The Indefinitive List of the Strongest Tornadoes Ever Recorded (Pre-1970): Part II | http://extremeplanet.me/2013/04/20/the-indefinitive-list-of-the-strongest-tornadoes-ever-recorded-pre-1970-part-ii/ live https://web.archive.org/web/20130731074041/http://extremeplanet.me/2013/04/20/the-indefinitive-list-of-the-strongest-tornadoes-ever-recorded-pre-1970-part-ii/ 2013-07-31 2013-06-23US Department of Commerce NOAA Info on the Udall Kansas tornado https://www.weather.gov/ict/udall 19 October 2020 www.weather.gov EN-US1955 Udall Tornado | Wichita Eagle http://www.kansas.com/2010/02/10/1174869/1955-udall-tornado.html dead https://web.archive.org/web/20131119071847/http://www.kansas.com/2010/02/10/1174869/1955-udall-tornado.html 2013-11-19 2013-10-09 The tornado later dissipated after traveling over 50 mi km out from the Oklahoma border to southeast of Wichita.
Almost immediately, volunteers and rescue workers descended into the darkness to aid the survivors. Ambulances and automobiles of all kinds rushed the growing numbers of injured to hospitals in three neighboring towns. The closest hospitals were William Newton and St Mary's Hospitals, 17 miles southeast in Winfield, the former of which took in 129 patients that night. Several were taken to St Luke's Hospital in Wellington, 23 miles to the southwest, while the remainder were taken to three hospitals in Wichita to the northwest.Minick, Jim. "Without Warning". p. 81, 85.
Aftermath
This tornado was the deadliest in the state's history. In Udall, 75-77 people were killed, and 270 were injured, which meant that about 70% of Udall's population were casualties of the tornado.Smith Michael The Greensburg Miracle – Where There's Life, There's Hope https://www.vaisala.com/sites/default/files/documents/The%20Greensburg%20Miracle%20-%20Where%20There%20is%20Life%20There%20is%20Hope.PDF March 7, 2025 Damage totals were over $2 million, with only one building in the entire town remaining habitable after the tornado. Among the people who helped with the cleanup were the crew of the film Picnic, which was being filmed in Halstead.Shaffer Bill The Summer of Picnic Kansas Heritage Spring 2005 13 1 https://www.kshs.org/publicat/heritage/2005spring_shaffer.pdf https://ghostarchive.org/archive/20221010/https://www.kshs.org/publicat/heritage/2005spring_shaffer.pdf 2022-10-10 live 14 September 2016 The Udall tornado sparked changes in the issuance of tornado warnings and technology.Nyman Jeremiah March 3, 2015 History Lessons: The devastating 1955 Udall tornado https://www.ksn.com/news/history-lessons-the-devastating-1955-udall-tornado/ March 10, 2025 Comparisons have been drawn with the Greensburg tornado, with improved technology and information relaying being credited with the relatively low death toll in Greensburg.
