Unrated tornado, Johnson, Texas, May 23, 2019

This Unrated tornado ran 0.1 miles across Terry County on May 23, 2019, touching down at 5:28 PM CDT and reaching 10 yards wide. It killed nobody.

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 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. Unratedthis tornado

    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

Another day of long-lived widespread severe weather was observed on the South Plains of West Texas on the afternoon and evening of the 23rd. The first report of severe weather was received at 1518 CST with the final report at 2309 CST. A persistent long wave trough over the western United States remained in place with a dryline moving into the South Plains in the afternoon. Numerous thunderstorms developed east of the dryline and took advantage of strong shear and instability and rapidly became severe. Most reports consisted of large hail with the largest report of baseball size hail near Shallowater (Lubbock County). Despite the strong shear and low cloud bases, only one report was received of a tornado. A brief anticyclonic tornado was observed west of Brownfield (Terry County). Additionally, very heavy rainfall caused flooding in portions of the southwestern part of the city of Lubbock (Lubbock County).

A trained spotter reported a brief anticyclonic tornado west of Brownfield.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. 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 Enhanced Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 19:45 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.
