From Five Pts to Reagor Spgs, this EF2 tornado ran 5.4 miles across Ellis County on May 3, 2021, touching down at 8:43 PM CDT and reaching 659 yards wide. It killed nobody and injured 8, and did $1.5 million 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 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 mphthis tornado
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.

What the Weather Service recorded
Numerous severe thunderstorms erupted along a cold front in the afternoon and evening hours. Many of the storms produced large hail, and a total of 6 tornadoes were recorded. The most significant tornado was an EF-2 in Ellis County, but an EF-2 tornado also occurred in Hill County. Several reports of golf ball sized hail were received, but the largest hail stone reported was 3 inches in Johnson County.
Damage started in the Five Points area along FM 876. The tornado continued northeast, and the first signs of EF-2 damage were observed near Johnston and Hollis Roads. The tornado then crossed I-35E where it struck 3 semis and one cargo van. Three injuries occurred in this location. Next, the tornado struck a scrap metal yard on the east side of I-35E and moved on to damage homes and electrical towers near and along HWY 77 and Butler Ln. EF-2 damage was also observed in this area, in particular to one home. Maximum estimated winds were 120 mph, and there were 5 additional injuries in this area. The tornado tracked farther east, did EF-2 damage to one home on FM 55, and then crossed FM 55 and dissipated.

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.
