The rating scale

EF4166 to 200 mph
Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

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
Scattered strong to severe thunderstorms affected portions of central and south-central Kansas generally west of the Flint Hills during the late afternoon and evening hours on the 2nd, in response to a weak cold front approaching from the north. The more notable reports include golfball to tennis ball size hail in Ellsworth, and winds estimated around 70 mph north of Kanopolis State Park.
A very thin rope like tornado touched down briefly. The tornado may also be considered a landspout. This can be attributed to the length of time the tornado was on the ground versus the distance it traveled.
From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

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.
