Research suggests that it is. A 2018 study found that tornado frequency generally decreased over the past four decades across Tornado Alley while increasing just to the east across the Lower Great Lakes and into the Deep South. The map from the study shows this (note the hashed areas). People used to worry about a tornado in downtown Dallas; these studies suggest downtown Memphis and Nashville are more at risk. Recent events confirm this: Nashville saw a tornado rip through the city in March 2020, and Memphis is no stranger to tornadic activity either. In fact, some meteorologists call this region "Dixie Alley," a nod to the increasing number of tornadoes in the South.
