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
A tornado was reported first touching down just inside the Marengo County line about 3 miles south of Dixons Mills. The storm then crossed U. S. Highway 43 about 2.5 miles south of Dixons Mills . Storm track was northeast...crossing County Road 37 and then across State Highway 10 just west of County Road 55. The storm then moved across County Roads 55 and 45. Almost all the damage along this track was to trees. The tornado appeared to be near tree top level along this path.The storm then moved across County Road 56 near Surginer just to the east of County Road 45. This is where most of the structural damage occurred. Two mobile homes were demolished. One home sustained major roof damage, while two others suffered roof and structural damage along County Road 56. Damage was also done to barns and outbuildings here. The tornado lifted back into the cloud just north of County Road 56. No injuries were reported.

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.
