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.

  1. EF065 to 85 mphthis tornado

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

  2. EF186 to 110 mph

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

  3. 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.

  4. 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.

  5. EF4166 to 200 mph

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

  6. 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.

  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

Widespread showers and thunderstorms developed along and ahead of a strong cold front as a powerful upper level storm system plowed into the southern plains during the afternoon hours of October 29th. Strong shear was in place across the region such that several tornadic thunderstorms developed...producing widespread wind damage across portions of northeast Texas, southwest Arkansas as well as northern Louisiana. These storms trained across the same general area such that flooding was widespread. Flooding was severe across northwest Louisiana where flooding was reported in many homes and businesses. Area bayous, creeks, rivers and lakes were already at high levels from the excessive heavy rainfall that fell earlier in the month. Thus, some lakes and bayous approached and succeeded their all time record stage levels.

An EF0 tornado touched down on Hwy. 67 about a half mile west of Clear Springs Road. Several trees were uprooted and snapped approximately 10 miles southwest of Texarkana, Texas. After the initial touchdown, the tornado moved northeast, producing sporadic tree damage. The tornado dissipated on Tri State Road just south of Hwy. 82. Winds were estimated at 75-85 mph range.

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

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 0.10 chance of a tornado within 25 miles. The outlook in force was issued at 19:57 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.
