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 mphthis tornado
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
F173 to 112 mph
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.

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
April 30, 2000 - Event NarrativeA big day for severe weather across northwest portions of the area. Several outflow boundaries, a dryline, and moist unstable air all helped contribute to thunderstorm development. There were several rounds of thunderstorms, the first wave was in the early morning hours, from about 3 am to 5 am. This activity developed in Young and Palo Pinto counties and moved eastward to affect Parker, Jack, Wise and Tarrant counties. Another event developed in the early evening, generally north and west of a Dallas, Glen Rose, Eastland line. Most of the activity was centered on Young, Jack, and Stephens county. A large tornado occurred near Olney (Young County) during this event. A continuation of aa tornado that began in Throckmorton county.
A brief touchdown was reported by storm chasers.

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.
