April is the cruelest month for tornadoes in eastern Tennessee. Records dating to 1883 show that April brings a huge spike in tornado activity in the 40 counties in eastern Tennessee, Southwest Virginia and Southwest North Carolina covered by the National Weather Service office in Morristown, Tenn. But so far, so good. April 2014 has shaped up as a dud, as far as tornadoes go. We haven't had any, yet, and this is the peak tornado season, said Anthony Cavallucci, warning coordination meteorologist for the National Weather Service's Morristown office.
