Dr. Steve Forbes of the Weather Channel is considered the foremost authority of severe weather in the United States. He is the inventor of the TorCon scale which gives the percentage that a tornado will hit within 50 miles of your location. Forbes analyzed historical data of tornado deaths and economic impact to come up with the "Top 10 Worst U.S. Tornados".
Interestingly, three of the top five were in Missouri. Three of the top ten happened just last year in 2011. One was in New England in 1953.
