03/21/11 Tornado Anniversary

On this day, 59 years ago, Tennessee had it's deadliest tornado move through 4 counties. It first touched down in Hardeman county, then moved through Chester and Henderson counties, before finally lifting  in Decatur county. There were 41 deaths and 158 injuries with this tornado. Because this was back in the 1950s, no real storm surveying was done by the National Weather Service like there is now, but estimates put the tornado at an F4 strength. It had a path length of 65 miles, and struck at 10:45pm. The Fujita scale (which rated this tornado an F4) is no longer the same scale that is used today. Now the Enhanced Scale is used. A comparison of the 2 charts is below.
