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 occluded surface low meandered near the eastern shore of Lake Superior during the late morning through early evening of the 12th. Simultaneously, the trailing cold front swept southeastward from southeastern Lower MI and northern IN to central Lake Erie and north-central/west-central portions of OH. Multiple multicell and supercell thunderstorms occurred along and ahead of the cold front in northern OH. These storms produced severe hail, damaging convective gusts, and two tornadoes in a warm sector comprised of moderate to strong MUCAPE and effective bulk shear, respectively, mixed-layer lifting condensation levels near 750 to 1500 meters AGL, and strong surface-based effective storm-relative helicity near 150 meters squared per second squared.
An EF0 tornado with estimated peak winds of 70 mph occurred on the southeastern outskirts of Nashville. This tornado began along Township Road 501, just south of OH-39 and ended just northeast of the intersection of Township Roads 51 and 259. As the tornado tracked southeastward, it uprooted or snapped trees and other trees had their tops sheared-off. No structural damage was observed.
From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

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 Enhanced Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 16:23 UTC.

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.
