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 mph
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
F173 to 112 mphthis tornado
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
Severe thunderstorms moved across Central Virginia during the afternoon of the 19th. These storms produced winds in excess of 55 MPH, large hail, and frequent lightning. In Orange County, silver dollar sized hail fell in Barboursville and dime sized hail fell on Hardwick Mountain. In Nelson County, trees were downed in the Gladstone area. Just west of Charlottesville, a tree was downed onto Old Ivy Road. The strongest storm produced an F1 tornado that uprooted and snapped several trees along an 11 mile path from extreme northern Albemarle County to southern Greene County. The tornado began just north of Loft Mountain, about 200 yards east of Skyline Drive. It moved eastward across County Line Mountain into Greene County, and crossed Route 601 at Muddy Run. The tornado damage path widened at this point from 30 yards to between 50 and 100 yards. The tornado continued east and traveled near the towns of Shady Grove and Dyke before finally dissipating a few miles east of Amicus. This storm also produced downburst winds to the south of the tornado's path that uprooted trees and downed power lines in southern Greene County. Trees were also downed just west of where the tornado formed just west of Skyline Drive in Rockingham County.
The tornado began just north of Loft Mountain, downed trees and moved into Greene County.
The tornado crossed into Greene County west of Dyke and dissipated just east of Amicus, downing several trees and power lines in its path.

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 15:56 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.
