The 1947 Glazier–Higgins–Woodward tornadoes were a series of related tornadoes spawned by a single supercell that swept through the U.S. states of Texas, Oklahoma, and Kansas on Wednesday, April 9, 1947. Most of the damage and all the deaths are still blamed on one large F5 tornado, known as the Glazier–Higgins–Woodward Tornado, that traveled nearly 125 miles from Texas to Oklahoma. This event was often compared to the Tri-State Tornado, because it was originally thought to have left a 219-mile path, but it is now believed to have a been part of a family of eight or nine tornadoes.
