From Stewarton to Wizard Wells, this EF0 tornado ran 1.8 miles across Jack County on March 18, 2020, touching down at 8:56 PM CDT and reaching 55 yards wide. It killed nobody, and did $25,000 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.
EF065 to 85 mphthis tornado
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
EF186 to 110 mph
Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.
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.
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.
EF4166 to 200 mph
Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.
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.
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
4 damage points were recorded along this path by NWS FWD, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 110 mph.
- Mobile home moved several feet back, shifted off concrete pillars. Windows broke. Shingle damage to roof, no loss of decking. Loss of second mobile home so winds may have been close to 105-110 mph in this location. Flip of 18-wheel truck bed. Damage to trees.
- Trees snapped at a level at or above roof line on this lower elevation home. Home sustained minor roof damage, but damage to the trees was more significant.
- Boat was displaced from house across the street. Wide swath of tree damage about 1/4 mile wide. Most trees snapped but some uprooted, possibly from saturated grounds.
- Roof was lifted off over the garage once the wind entered the garage through the bent doors. Boat and trailer were thrown across the street and considerable tree damage nearly a quarter mile wide was noted around this property.

What the Weather Service recorded
An upper level trough near the region contributed to several rounds of severe weather over a 2 day period. The first round was an MCS that resulted in flooding across parts of North Texas. The second round resulted in a few tornadoes to the west and northwest of the DFW Metroplex. The final round was afternoon convection that produced some small hail around the DFW Metroplex.
A severe thunderstorm in Jack County developed a tornado southeast of Jacksboro between Highways US-281 and US-380. The storm also produced two additional areas of straight line wind damage in the county. The tornado started northeast of US-281 in an open field and damaged several low-topped tree limbs. The tornado then crossed over a ridge and onto Dos Equis Ranch Road where it blew a manufactured building off its blocks. The building was secured with up-to-date straps. The tornado then continued northeast before lifting shortly after passing Dos Equis Ranch Road. The tornado was on the ground for approximately 1.8 miles and was 55 yards in width. It was rated an EF-0 with max winds estimated at 80 mph.

The forecast that day
The Storm Prediction Center had this point in a Enhanced Risk, with a 0.10 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 00:48 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.
