On May 23–24, 1946, a tornado outbreak occurred across the Central and Midwestern United States. Over two days at least 15 significant tornadoes struck parts of Kansas, Nebraska and Oklahoma, killing four people and injuring 42 others.[1] [2] The storm system also caused numerous other impacts including hail, heavy rains, and damaging lightning strikes.
This weather event happened before the invention of an official ratings system for tornadoes in 1950. The events were later assessed by tornado expert Thomas P. Grazulis, and rated unofficially on the Fujita scale. Grazulis documented 15 significant tornadoes (F2+), but the true number of tornadoes for this outbreak is most likely higher.[1]

Grazulis notes this was likely a tornado family. | ||||||
