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 mphthis tornado
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 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.
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
Heavy rain from thunderstorms lead to flash flooding across portions of Pulaski and Jackson counties during the late afternoon and evening hours of July 1, 2015. A brief, and quite unexpected, tornado touched down briefly in Pulaski county. A funnel cloud from the same storm/shower that produced the tornado was sighted in Whitley county later in the evening.
A weather service storm survey confirmed that an EF-0 tornado briefly touched down near Nancy, KY. The estimated maximum winds in the tornado were 75 mph. The path width of the tornado was approximately 100 yards, with a path length of 0.3 miles. The tornado was on the ground for less than a minute. Minor tree damage and structural damage were observed at the intersection of Hwy 1664 and Pierce Road. An old barn collapsed due to the storm and some shingles were blown off a home. A few tombstones in a nearby cemetery were overturned by the tornadoes winds. This tornado developed from a shower. No thunder or lightning was ever observed in the area.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.
The forecast that day
The Storm Prediction Center had this point in a Marginal Risk. The outlook in force was issued at 19:59 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.
