The rating scale
Tracks are drawn in the color of the rating. The Enhanced Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.
EF065 to 85 mph
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
EF186 to 110 mph
Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.
EF2111 to 135 mphthis tornado
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.
EF3136 to 165 mph
Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.
EF4166 to 200 mph
Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.
EF5over 200 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
Rich low level moisture rapidly lifted north across the Plains on Saturday May 25th with storms initially developing along a developing dryline across western Oklahoma. One particular storm gained strength as it tracked north of the Oklahoma/Kansas border. This supercell thunderstorm produced a brief tornado in Barber County before tracking east and producing an EF-2 tornado west of Anthony. What made this tornado unique was that it did not form from the main mesocyclone associated with the supercell, but rather from the supercells interaction with one of the storms lifting due north out of Oklahoma.||The tornado threat was short-lived though as storms lifting north out of northern Oklahoma merged with the supercell which transitioned the threat to damaging winds. This cluster of storms produced 60 to 75 mph winds as it tracked across Wichita which caused widespread tree damage and widespread power outages.||Around midnight additional storms developed over southern Cowley County and rapidly starting rotating which required a tornado warning as it tracked toward the Kansas/Oklahoma border. This storm went on to produce just shy of baseball size hail in Tyro and 80 mph winds in Caney.
The tornado tracked northwest and damaged a farmstead west of Anthony. What made this tornado unique was that it did not form from the main mesocyclone associated with the supercell, but rather from the supercell's interaction with one of the storms lifting due north out of Oklahoma. EF-2 damage was found at a farm about 8 miles west of Anthony where large sections of a roof structure were removed. A couple tree trunks were snapped with another one uprooted. One outbuilding was totally destroyed.

The forecast that day
The Storm Prediction Center had this point in a Moderate Risk, with a 0.15 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 20:09 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.
