Nebraska, surprisingly, has been home to a "disproportionate" share of the handful of powerful October tornadoes that have occurred since 1950.
The Omaha area office of the National Weather Service delved into tornado statistics and found that six tornadoes of F4 strength or greater have occurred in the month of October nationwide since 1950. Of those six tornadoes, two occurred in Nebraska, including the one that hit Wayne on Friday.
Here are the records, in chronological order:
Connecticut, Oct. 3, 1979, an F4.
Oklahoma, Oct. 5, 1970, an F4.
Iowa, Oct. 14, 1966, an F5.
Louisiana, Oct. 3, 1964, an F4.
Nebraska, Oct. 29, 1956, an F4.
Nebraska, Oct. 4, 2013, an EF4.
Because there are so few powerful tornadoes recorded in October, there's no real significance to the fact that a third (two of 6) occurred in Nebraska — unless of course it's a piece of trivia worth trotting out to friends.
Note the use, above of F4, F5 and EF4. Tornadoes since 1950 have been rated according to the Fujita, or F scale. In 2007, an updated Fujita scale was put into use, so tornadoes from that year forward are ranked according to the Enhanced Fujita, or EF, scale.
