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
Showers and thunderstorms developed in association with a frontal system moving through the region. Some of these storms produced a few tornadoes, hail, and damaging wind gusts.
An EF1 tornado developed in the evening of April 9th near Zetus Road and Russell Lane. The tornado produced primarily tree damage before traveling southeast across Palmetto Trail and then crossing near Watts Lane and Norman Trail. The tornado became most intense in this area where a shed was damaged by falling trees on Norman Trail while on Watts Lane a large stand of young pines fell, as well as some power poles and lines. The tornado continued southeast where more tree damage was documented as well as roofing damage to some structures. It was in this area that the path was most clearly defined with stands of trees significantly damaged in a clear trajectory to the southeast. The tornado crossed Hwy 84 near Breckenridge Lane where out buildings were heavily damaged or destroyed. The tornado then began to weaken but continued to produce intermittent tree damage south of the highway before dissipating north of Auburn Drive. Estimated peak winds were 95 mph.

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 Moderate Risk, with a 0.10 chance of a tornado within 25 miles. The outlook in force was issued at 01:19 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.
