What EF2 means. On the Enhanced Fujita scale, EF2 is considerable damage: roofs torn off well-built houses, mobile homes destroyed, large trees snapped or uprooted, consistent with estimated gusts of 111–135 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

Numerous homes were damaged in the town of Dodson with several completely destroyed. One mobile home was picked up and moved 30 feet west of its original location where it was destroyed with parts of the frame wrapped around a neighboring home. The two injuries occurred in the destroyed home. Approximately 27 mobile homes and 11 built in place structures in the center of Dodson sustained severe damage from snapped or falling trees and/or wind damage. A mobile home in the center of Dodson was rolled off its foundation and destroyed. The tornado touched down on the southwest side of town along US 167 and moved northward 1.5 miles before lifting along State Route 1235.

The wider storm

A very unstable airmass developed across the four state region during the afternoon hours of May 2nd. A weak cold front had moved southward during the morning hours into southeast Oklahoma and southwest Arkansas and had stalled. A weak shortwave moved into the Texas Hill County and produced enough lift...along with the development of a strong low level jet...for strong to severe thunderstorms to erupt across the region. The storms initially developed as supercells...producing large hail and isolated tornadoes but then evolved into a squall line. Strong straight line winds accompanied the squall line with winds in excess of 100 mph reported with some storms. There were also isolated tornadoes reported within the squall line itself. Damage was extensive across the region but overnight...the repeated training of storms resulted in a widespread flash flooding event. Numerous counties and parishes were flooded with rainfall amounts in excess of 6 inches in a 12 hour period common. By the time the event ended...there were five different line echo wave patterns that developed across the four state region the afternoon of May 2nd through the morning hours of May 3rd.

Began near Dodson (32.0730, -92.6610).
