[PAR] [TLE] Tri-State Tornado [SEP] The Tri-State Tornado of Wednesday, March 18, 1925 was the deadliest tornado in U.S. history.  It was also the most exceptional tornado during a major outbreak of at least twelve known significant tornadoes, spanning a large portion of the Midwestern and Southern U.S.  The tornado alone inflicted 695 fatalities, more than twice as many as the second deadliest, the Great Natchez Tornado of 1840.  The 151 to track left by the tornado was the longest ever recorded in the world as it crossed from southeastern Missouri, through southern Illinois, then into southwestern Indiana.  Although not officially rated by NOAA, it is recognized by most experts (such as Tom Grazulis<ref name="F5/F6"> </ref> and Ted Fujita) as an F5 tornado, the maximum damage rating issued on the Fujita scale. [PAR] [TLE] 1947 Glazier–Higgins–Woodward tornadoes [SEP] The 1947 Glazier–Higgins–Woodward tornadoes were a series of related tornadoes spawned by a single supercell that swept through Texas, Oklahoma, and Kansas on 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 8 or 9 tornadoes.
