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.

The damage survey
65 damage points were recorded along this path by NWS HUN, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 100 mph.
- damage caused by tree falling on house
- fell across highway 20 and was facing north
- trees fell on house, fell west
Survey points are preliminary and are the raw material the published rating was built from. Source: NWS Damage Assessment Toolkit.
What the Weather Service recorded
A quasi-linear convective system (QLCS) dropped southward into the Tennessee Valley during the afternoon and evening hours. The airmass was very unstable, and despite low to moderate low to mid level wind shear, multiple swaths of damaging winds occurred. Within these pockets of winds, a few weak and mostly short-lived tornadoes developed. The most concentrated wind and tornado damage occurred in portions of Lauderdale, Colbert, and Lawrence Counties including the Shoals region of Florence, Sheffield, Muscle Shoals, Town Creek and Courtland. Other short-lived tornadoes occurred in Madison, Morgan and Cullman Counties. Unfortunately, one person was killed by a falling tree near West Point in Cullman County.
A tornado touched down along the south riverbank of the Tennessee River in Sheffield. The tornado initially produced substantial tree damage along Alabama Avenue along with minor roof and structural damage to several homes. The tornado then moved southeast uprooting or snapping numerous hardwood trees in the residential neighborhoods of Sheffield. Here many homes were damaged by falling trees or flying debris. Several homeowners said they witnessed seeing a funnel cloud approaching from the north. The most substantial damage was noted along Little Rock Avenue where power poles were snapped or pushed over. Many residents were without power due to the storm.||The tornado narrowed somewhat as it moved southeast toward Tuscumbia. Damage was noted to trees just east of the Helen Keller Hospital complex. Power lines were broken and transmission lines were bent over along Elm Street. A large light tower was completely destroyed at Deshler High School. The tornado continued to produce sporadic damage as it approached Highway 43 rolling over an un-anchored building and producing minor damage at a car dealership. The tornado crossed Highway 72 Alternate with mainly tree damage noted before it apparently lifted along Spring Valley Road.
A tornado touched down in the southeast corner of Colbert County in the LaGrange community. The tornado touched down along Poplar Creek Loop west of County Road 48 (County Line Road). Here, numerous trees were uprooted or had large sections of branches snapped. The tornado continued to move southeast crossing County Line Road. Damage to mainly softwood trees was noted along Wolf Springs Road as the tornado straddled the Bring Crossing into Lawrence County.

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.
