 A thorough re-analyses project found that it was probably one continuous tornado for most of its path, likely bounded by separate tornadoes at the beginning and end of the very long track (VLT) tornado, and likely another significant tornado spawned many miles later.However, many other exceptionally VLT events were later found to be tornado families with much shorter tornado path segments than originally thought, notably the Woodward, Oklahoma tornado family of April 1947 and the Charleston-Mattoon, Illinois tornado family of May 1917.Tornado families can be a result of satellite tornadoes, cyclic tornadogenesis, or some combination thereof.
