What EF3 means. On the Enhanced Fujita scale, EF3 is severe damage: whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, consistent with estimated gusts of 136–165 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

The wider storm

A warm front lifted slowly through North Mississippi during the early evening of April 27, 2014. The airmass south of the warm front was very unstable and a couple of supercells developed along the warm front over Northwest Mississippi with damaging winds and large hail. The warm front lifted north of North Mississippi leaving a very unstable airmass behind. A sutble upper level disturbance triggered thunderstorm developoment during the early morning hours of April 28, 2014. These thunderstorms eventually developed into a mesoscale convective system that tracked across much of Northwest Mississippi with a few reports of large hail and damaging winds. Later that same day an approaching cold front combined with a potent upper level disturbance to trigger supercells across Northeast Mississippi. This resulted in a strong tornado that tracked near Tupelo, Mississippi and several reports of large hail.

Began near Centerville (34.3788, -88.5430).
