The rating scale
Tracks are drawn in the color of the rating. The Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.
F040 to 72 mphthis tornado
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
F173 to 112 mph
Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.
F2113 to 157 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.
F3158 to 206 mph
Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.
F4207 to 260 mph
Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.
F5261 to 318 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 damage survey, conducted by National Weather Service personnel from the Peachtree City, Georgia office, determined that an F0 tornado briefly touched down at the Forest Square Shopping Center on Georgia Highway 54, Jonesboro Road, near the southwest corner of Fort Gillem. This is about 3 miles southeast of Atlanta's Hartsfield International Airport. Six buildings sustained considerable damage, mainly to roofs, windows, and to exteriors. A pawnshop in the shopping center lost part of its roof and a Pizza Hut, immediately next door, lost all of its windows. Several other buildings in the area lost windows from flying debris. A nearby Pep Boys Auto Parts store lots a large portion of its roof and exterior awnings. The flying debris from the roof of the damaged buildings, particularly the Pep Boys store, caused damage to 15 to 20 cars parked nearby. Many of the cars had their rear windows shattered out and appeared as if they had been hit with a major hailstorm, although no hail was reported in the area. It is believed that rock pebbles from the roofs of the damaged buildings were largely responsible for this occurrence. The flying debris and glass caused injury to 8 people. The injuries were described as being mainly cuts and bruises, although one person suffered a broken arm. Power lines were also reported down in the same area.
From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.
The warnings
No tornado warning for this county appears in the archive as in force at the moment the tornado touched down.
Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.
The forecast that day
The Storm Prediction Center had this point in a Slight Risk. The outlook in force was issued at 16:24 UTC.
SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

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.
