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.

What the National Weather Service wrote

An EF-3 tornado moved northeast out of Clay County, Mississippi into Chickasaw County just south of Trebloc. The tornado weakened to an EF-1 as it moved into Chickasaw County. One home was destroyed which resulted in two injuries. Several other homes sustained minor damage from fallen trees. A barn was damaged and trees were uprooted near Highway 8 and Highway 47. Numerous trees were knocked down along the path. The tornado continued northeast into Monroe County, Mississippi.

The wider storm

A stationary front remained draped across Southern Missouri into Western Kentucky from April 24th, 2011 into April 25th, 2011. A very warm and unstable atmosphere was in place across the Mid-South ahead of the front. A low pressure system developed along the front and interacted with the unstable environment which helped produce several rounds of severe storms into the evening of April 26th, 2011. As a result of the severe storms, the front sank south during the early morning hours of April 27th, 2011 as a secondary low pressure system developed along the front. As a result, another round of severe storms fired during the afternoon hours ahead of the low pressure center. Additional severe storms fired along the trailing cold front. Tornadoes, large hail, damaging winds, flash flooding occurred as a result of the severe storms.

Began near Mc Condy (33.8116, -88.8454).
