The rating scale
Tracks are drawn in the color of the rating. The Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.
F040 to 72 mphthis tornado
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
F173 to 112 mph
Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.
F2113 to 157 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.
F3158 to 206 mph
Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.
F4207 to 260 mph
Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.
F5261 to 318 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.

What the Weather Service recorded
The afternoon and evening of the 13th brought an active severe weather episode to West Texas. A cold front was slowly progressing across the southern plains...stretching from southwest Oklahoma into southeast New Mexico by late afternoon. A surface trough of low pressure was located south of the front across the Trans Pecos Region. Numerous severe thunderstorms developed across the area, a few of which took on supercellular characteristics. These storms resulted in hail to the size of baseballs and one tornado. Despite the amount of severe weather which took place across the area on the 13th, reports of damage were very limited.
A commercial airline pilot reported a brief tornado in southeast Mitchell County. Radar representation of the storm indicated the tornado was likely near Highway 208 about 15 miles SSE of Colorado City. No damage was reported by the local authorities.
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. The outlook in force was issued at 00:57 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.
