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.
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.

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DODGE CITY KS 245 PM CDT WED JUL 10 2002 DAYS 1-2... THE UPPER LOW WAS STARTING TO DIG DOWN THE EASTERN PLAINS TODAY, WITH A PREFRONTAL TROUGH IN SOUTHERN KS, AND THE TRUE COLD FRONT IN NORTHWEST KS. ANOTHER STRONGER COLD FRONT WAS MOVING INTO NORTHEAST SOUTH DAKOTA. THE SCENARIO WE ENVISION IS FOR STORMS TO DEVELOP ALONG THE PREFRONTAL TROUGH THIS AFTERNOON AND THEN MOVE SOUTH INTO OKLAHOMA LATER THIS EVENING. OVERNIGHT, A FEW MORE STORMS COULD DEVELOP ALONG THE TRUE FRONT AS IT STARTS TO MOVE TROUGH CENTRAL/SW KS. TEMPS SHOULD BE A FEW DEGREES COOLER THURSDAY BEHIND THE LEADING FRONT. EVEN COOLER AIR WILL MOVE IN FRIDAY. GOING FCST SEEMS CONSISTENT WITH THE ABOVE THINKING, SO MAJOR CHANGES ARE NOT ANTICIPATED. THE ONLY REAL CHANGES WILL BE TO KEEP POPS GOING ALL NIGHT TONIGHT AND NUDGE TEMPS DOWN A COUPLE DEGREES FOR FRIDAY. DAYS 3-7... MODELS REMAIN CONSISTENT WITH DEVELOPING A ERN CONUS TROF OVER THE WEEKEND AND AMPLIFYING OUR WESTERN CONUS RIDGE. ON MONDAY A UPPER LOW OVER THE LOWER MISSISSIPPI VALLEY STARTS TO SLIDE BACK WESTWARD TOWARDS OK/TX. THE 12Z AVN WAS EVEN FURTHER WEST WITH THIS LOW BY 12Z MONDAY THAN THE MRF/ECMWF AND IF VERIFIED WOULD RETARD THE WARMUP AND POSSIBLY BRING A SLT CHANCE FOR PCPN TO OUR ERN CWA. AT THIS TIME CONFIDENCE WITH THIS FEATURE IS LOW BUT GIVEN THE PREVIOUS FORECAST WAS TRENDING TOWARDS SLT CHC POPS LATE TUESDAY HAVE OPTED TO LEAVE MENTION OF LOW POPS IN AT THIS TIME. AS FOR TEMPS WILL CONTINUE WITH PERSISTENCE AND WARM TEMPS BACK INTO THE 90S THROUGH THE FIRST OF THE WEEK BUT WILL TRIM A FEW DEGREES OFF THE ERN 1/2 OF THE CWA.

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.
