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
Between 6:10 PM and 6:25 PM EDT, a line of thunderstorms moved east from Orange County into Spotsylvania County. Strong winds associated with the gust front ahead of the storms produced scattered tree damage in Eastern Orange County and Western Spotsylvania County. Areas affected include Gold Dale, Mine Run, Paytes, Granite Springs, and Porters. Over 100 trees were damaged; some were uprooted, some were snapped, and others lost large branches. The strong winds also bent several home antennas and blew off several roof shingles. A small tornado developed with one of the storms near Mine Run. The tornado first touched down around 6:17 PM EDT on the Orange/Spotsylvania County line in a small community 1 mile north of Paytes. The tornado travelled southeast about 3 1/2 miles and lifted just east of Mastins Corner around 6:23 PM EDT. The average path width was about 100 yards. Much of the damage was rated F0 for 40 to 70 mph winds, but some locations received 70 to 90 mph winds and F1 damage. The F1 damage occurred around 2 miles east of Paytes through a densely wooded area where numerous large trees, both pines and hardwoods, were uprooted or snapped. The hardwoods did not have leaves at the time, so a stronger wind was required to damage them. Eight homes along the path of the tornado sustained minor damage,and seven sheds were damaged or destroyed. Most of the structural damage occurred in a residential community 1 mile northeast of Paytes. The same storm system was also responsible for downing trees and power lines as it passed through the Fredericksburg area. The storm hit Fredericksburg around 7:00 PM EDT and left about 5,000 customers without power.

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 20:11 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.
