EF0 tornado, Arcadia Park to Eagle Ford, Texas, May 8, 2014

From Arcadia Park to Eagle Ford, this EF0 tornado ran 0.5 miles across Dallas County on May 8, 2014, touching down at 3:15 PM CDT and reaching 120 yards wide. It killed nobody, and did $80,000 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 mphthis tornado

    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 mph

    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.

The damage survey

13 damage points were recorded along this path by NWS FWD, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 80 mph.

What the Weather Service recorded

Large scale lift ahead of an upper level shortwave, combined with ample instability and adequate moisture across the region, resulted in numerous thunderstorms across the region. Scattered convection developed in the afternoon hours but a linear MCS had formed by the late afternoon hours. Hail up to the size of golf balls was reported but the most significant damage occurred in Dallas County due to damaging wind gusts. A weak tornado produced minor damage in west Dallas, but damaging downburst winds produced numerous tree damage and brought down power lines across areas in and around the city of Dallas. Heavy rainfall also produced flash flooding in Dallas and also in Hunt County. One fatality was reported in the Dallas area due to a car crash on a wet roadway.

A National Weather Service Storm Survey found evidence of a tornado that produced EF-0 damage to a warehouse building. Several windows were blown out of a warehouse in Cockrell Hill. The building suffered roof damage as well, as the tornado moved generally from the southwest to the northeast.

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

The warnings

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down. One was issued for the county at another hour that day.

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 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 20:03 UTC.

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.
