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.

What the Weather Service recorded
A NWS storm survey determined an F0 tornado touched down 4 miles west of the town of Watha. It snapped 12-15 pine trees up to 18 inches in diameter. One tree hit the side of a house, with minor damage. The tornado complete destroyed a shed in this area. Moving southeast, the tornado snapped six small pine trees, and a wood fence was blown over. More damaged was observed east-southeast of the previous damage, where a barn roof was blown off, and debris was strewn east approximately 100 yards. The minimal tornado then turned on a more east-northeast path, with damage observed east of Watha. Two large trees were uprooted, and a brick chimney was toppled. Eyewitness accounts reported strong rotation in the clouds, just off the ground. The damage path ended 3.5 miles east of Watha, where a couple dozen pine and hardwood trees were snapped, 10-40 feet above the ground.

The warnings
12 minutes of warning. NWS ILM issued a tornado warning for this county at 18:25 UTC, 12 minutes before the tornado touched down, in force until 19:15 UTC.

|---|---|---|---|

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. 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 Slight Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 12:31 UTC.
SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

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.
