This F5 is commonly known as the “Ruskin Heights Tornado” because of the tremendous damage inflicted there. It has also been called “The Kansas-Missouri Tornado” and “The Ottawa-Kansas City Tornado”. It developed southwest of Williamsburg, KS, traveled close to 70 miles and ended near Knobtown, MO. This tornado was the strongest of 35 that occurred on May 20, 1957.
Per the Climatological Data National Summary (CDNS), a supercell formed south of Emporia and moved NE toward the southern parts of Kansas City. A number of tornadoes and funnel clouds were produced. One caused damaged near Hartford, KS. Another hit near the Verdigris River. This Ruskin Heights Tornado was the main one of the family traveling through Franklin, Miami, and Johnson Counties in KS and ending in Jackson County, MO.
A total of 44 fatalities were reported. The SPC only lists 207 injuries. Thomas Grazulis in Significant Tornadoes states the injury count at 531.
