EF2 tornado, Coahoma, Texas, May 26, 2014

This EF2 tornado ran 1.0 miles across Howard County on May 26, 2014, touching down at 5:38 PM CDT and reaching 400 yards wide. It killed nobody, and did $45,000 of property damage.

The rating scale

Tracks are drawn in the color of the rating. The Enhanced Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.

  1. EF065 to 85 mph

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. EF186 to 110 mph

    Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

  3. EF2111 to 135 mphthis tornado

    Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.

  4. EF3136 to 165 mph

    Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.

  5. EF4166 to 200 mph

    Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

  6. EF5over 200 mph

    Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.

  7. Unrated

    The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

What the Weather Service recorded

An upper-level low was centered over northern New Mexico. The atmosphere was very unstable with cooling occurring in the middle levels. A very moist air mass was in place, and the ground was already saturated from recent rainfall making conditions ideal for flash flooding. An upper-level disturbance that was rotating around the upper low moved over West Texas which increased the lift over the area. There was also an increase of wind speed and change of wind direction with height in the atmosphere which allowed for storms to rotate easier. These conditions combined to produce tornadoes, hail, high winds, and flash flooding in West Texas.

A thunderstorm moved across Howard County and produced a tornado near Coahoma. A storm spotter reported a rain-wrapped tornado that crossed Interstate 20 near Coahoma. An Ampscot 640 pump jack that weighed 78,000 pounds was overturned. This tornado was rated a high end EF-2 with winds between 111 to 135 mph. It was not possible to determine the track of this tornado due to the abundant rainfall, wet soil, and lack of vegetation so the track is estimated. The path width of the tornado was also estimated. The cost of damage is a rough estimate.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The forecast that day

The Storm Prediction Center had this point in a Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 19:41 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

What this means

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
