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 mph
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.
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
Scattered supercell thunderstorms developed on the afternoon of the 28th and persisted through the evening producing several severe storms despite weak background forcing. Strong instability developed while the atmosphere became uncapped which allowed these supercell thunderstorms to develop. A slow moving storm near Vigo Park produced a brief tornado over an open field. More widespread thunderstorms evolved late in the evening while tracking from west to east over much of the South Plains and Rolling Plains. In Lubbock, a tree hit by lightning fell on a vehicle. These widespread slow moving storms produced extensive flash flooding especially over Lubbock County. Several roads were closed due to flooding with numerous stranded vehicles. After the cluster of thunderstorms moved east of Lubbock, a heat burst was observed at Reese Center (Lubbock County) within a stratiform region. A peak wind gust of 67 mph was observed with this heat burst as well as a 15 degree temperature increase.
A video shared on social media showed a brief tornado southwest of Vigo Park in an open field. No damage was known to have occurred.

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 Marginal Risk. The outlook in force was issued at 19:50 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.
