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 mphthis tornado
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
A compact weather system moved through the region on Thursday May 11th and brought a round of severe storms during the late morning and afternoon hours. Most of the events were damaging winds but there were a few instances of hail and one tornado in SE Arkansas.
A tornado touched down east of Crossett and south of Hamburg near Highway 425, where it snapped and scattered tree limbs across the property of a community church. The tornado continued along Highway 425 as it uprooted hardwood and softwood trees along the forest line. It then damaged the roof of a house along Highway 425, where it also snapped the trunk of a softwood tree and uprooted several trees in the yard of the residence. The tornado continued northeast, crossing Highway 425, where it struck another residence. A wooden car port was blown across the yard, along with a portion of the roof being damaged on the house. Several large, hardwood trees were uprooted on the far northeastern edge of the property. The tornado weakened and lifted shortly after crossing Ashley County Road 97, where small limbs were scattered across the road. Estimated peak wind speeds were 107 mph.

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.
