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

A tornado formed along Farm to Market Road 2401. The tornado was narrow, 50 to 75 yards wide, and moved almost parallel and just south of FM 2401 during a 1.8 mile stretch before weakening somewhere near Highway 137. A small barn or outbuilding was destroyed by the tornado at approximately 7:28 pm. One wall of the structure remained. This type of damage is indicative of EF-1 damage with winds of approximately 100 to 110 mph. Pieces of the metal roof were blown northeastward across FM 2401 into an open field. Two silos/storage tanks were also displaced from their original locations. There was a stretch of 32 power poles that were snapped off within a few feet of the ground which is indicative of low-end EF-2 damage. Wind speeds necessary to produce this type of damage are estimated at around 120 mph. This tornado was rated as an EF-2. The cost of the damage is a very rough estimate.

The wider storm

A deep upper low was over New Mexico with strong lift and instability over southeast New Mexico and West Texas. There was a dryline and cold front that moved across the area, and there was a lot of wind shear in the atmosphere. Good moisture was present to the east of the dryline. This combination of moisture, lift, instability, and wind shear contributed to thunderstorms that produced large hail, severe wind gusts, and tornadoes.

Began near St Lawrence (31.6706, -101.6766).
