Tornado outbreak of May 21–24, 1952
A destructive severe weather and tornado outbreak struck the Central Plains, Great Lakes, Southeastern United States over a four day period. Multiple strong tornadoes were confirmed as well as widespread severe hail and wind, lightning, and heavy rain. One violent F4 tornado, which may have reached F5 intensity, caused severe damage between Lawrence and Kansas City, Kansas, injuring three people. Although the tornadoes themselves only caused eight injuries, scores of fatalities and additional injuries came from the non-tornadic effects as well. Meteorological synopsis
Two low-pressure systems formed over the Central Plains; the first one formed over Southeast Colorado on May 21 and moved eastward before moving northeastward in front of a second, slower moving low-pressure center that formed over south central South Dakota and moved into northeastern Nebraska. Both these lows moved eastward before the first one dissipated over Eastern Iowa while the other followed generally the same path as its predecessor. It moved through the Great Lakes region through May 25, before acceleration northeastward into Ontario, Canada. In the meantime, the complex setup led to a large area of severe thunderstorms, some of which became tornadic. Confirmed tornadoes
