EF0 tornado, Canadian Hemphill Ar to Glazier, Texas, May 16, 2016

From Canadian Hemphill Ar to Glazier, this EF0 tornado ran 0.1 miles across Hemphill County on May 16, 2016, touching down at 8:52 PM CDT and reaching 25 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 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.

What the Weather Service recorded

A surface low pressure system over northeast New Mexico moved southeast during the late afternoon and evening hours. A cold front moved southeast across the panhandles from northwest to southeast behind the low pressure system. Severe thunderstorms developed across northeast New Mexico during the afternoon and then moved southeast across the panhandles. Low level shear helped to create an environment favorable for tornadic supercells in the Texas Panhandle. Tornadoes were well documented by spotters and storm chasers through photos and video, and four caused minor damage.

A brief tornado crossed Highway 60 about 3 miles south of Canadian. Minimal tree damage was found, consistent with EF-0 damage and estimated peak winds of 74 mph. A storm spotter witnessed this tornado.

A narrow tornado track of tree damage was found by the survey team. The tornado was reported by several chasers and spotters. Tree damage was consistent with EF-0 damage and estimated peak wind of 75 mph.

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.

The county was under a severe thunderstorm watch, issued at 19:31 UTC and running to 04:13 UTC.

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 01:26 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.
