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.

  1. F040 to 72 mph

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. F173 to 112 mph

    Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

  3. F2113 to 157 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.

  4. 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.

  5. F4207 to 260 mph

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

  6. 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.

  7. 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

The F2 tornado over Johnson County crossed into Newton County about 4.5 miles southeast of Fallsville. The tornado continued to track to the northeast for 1.8 miles, before lifting 4.5 miles east-southeast of Fallsville. Since the tornado tracked across a national forest, damage along the path of the tornado consisted of numerous downed trees.

A strong tornado touched down in Newton County, tracking from 3.2 miles south-southwest of Swain to 4.5 miles east-southeast of Jasper. The thunderstorm that produced this tornado was the same storm that dropped a tornado over Johnson and southern Newton Counties a little earlier that evening. Significant damage occurred to an Inn and restaurant on Highway 7 in the Gum Springs community, or about 5 miles south-southeast of Jasper. The restaurant on the upper floor of the structure was destroyed. The roof was blown to the northwest, ending up across the highway from the building. The rear wall of the building went in the opposite direction, landing on a slope below the building. The tornado also damaged several houses and destroyed a number of outbuildings. Hundreds of trees were also blown down the entire path of the tornado.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

The warnings

21 minutes of warning. NWS LZK issued a tornado warning for this county at 02:03 UTC, 21 minutes before the tornado touched down, in force until 03:00 UTC.

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 Moderate Risk. The outlook in force was issued at 01:06 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.
