to be fair a lot of technical weather folks feel it should be...they even gave it own name...Dixie Alley
"Dixie Alley has nearly the same number tornadoes ranked F-3 or higher as Tornado Alley but there are more tornado deaths in Dixie Alley."
There is such a very loose un-verified definition of what tornado alley even is to be able to report on.
some of the largest super outbreaks of tornado's included much of TN.
