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.

What the Weather Service recorded
An upper level low over the eastern Gulf of Mexico allowed brought abundant tropical moisture to the region. With all of this moisture scattered showers and thunderstorms developed along sea breeze and outflow boundaries. A few of these storms became severe producing hail and a tornado.
A EF-0 tornado affected the community of The Acreage during the pre-dawn hours on May 14th. Damage consisted primary of snapped tree branches, uprooted trees and downed fences and power lines along the tornado's path. Several homes suffered minor roof damage in the form of shingles being blown off. Two homes sustained damage to side doors, and one home had a set of window panes blown out. Several sheds were damaged, a few horse stables lost their covering, and a chicken coop was destroyed. Estimated peak wind was in the 75-80 mph range.

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.
