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
A warm front lifted north across East Texas and North Louisiana to along the Arkansas/Louisiana border during the afternoon hours of December 19th, focusing showers a large area of rain north of this boundary over portions of extreme Northeast Texas, Southeast Oklahoma, and Southwest Arkansas. Meanwhile, much warmer and humid air was found south of the front across Lower East Texas and Northcentral Louisiana, resulting in moderate surface instability. Meanwhile, a surface low developed during the afternoon over North Texas along a weak cold front, associated with a strong upper level trough of low pressure that progressed east across Westcentral and North Texas during the afternoon and evening. Steep lapse rates aloft enhanced instability across the warm sector south of the warm front, with adequate shear present and strong upper level forcing ahead of the trough leading to the development of stronger, more surface based showers and thunderstorms. These storms became severe as they moved into Southern Cherokee County Texas, with an isolated tornado touching down just south of Rusk. Other reports of wind damage were received with these storms as they slowly marched east northeast across East Texas south of Interstate 20. Locally heavy rainfall also accompanied these showers and thunderstorms, which trained for a few hours over the same areas resulting in flash flooding across portions of Southern Cherokee, Gregg, and Southwest Panola Counties. These storms gradually weakened as they approached the Lower Toledo Bend Country during the late evening hours.
An EF-2 tornado was maximum estimated winds near 115 mph touched down across a heavily wooded areas just south of FM 4251 northeast of Reklaw, where it snapped and uprooted numerous trees. This tornado destroyed a nearby cabin adjacent to a pond where it was lifted off its pier and beam foundation and moved it about 15 yards into a heavily wooded area. A fiberglass fishing boat was lofted and unable to be found. The tornado continued east across a heavily wooded area before crossing County Road 4234 where numerous trees were snapped and uprooted. This tornado lifted after crossing County Road 4232 southwest of the Laneville community.

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.
