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.

An outbreak of severe thunderstorms and tornadoes affected parts of west Texas during the afternoon and evening of the 5th. Thunderstorms developed along a stationary frontal boundary over the western low rolling plains and the northeastern Permian Basin during the late afternoon. These storms evolved into supercells, and one storm produced a series of tornadoes across southern Borden and northern Howard Counties. By mid evening, a small cluster of organized severe storms evolved and produced more widespread hail, damaging winds, and heavy rainfall. Damages to agricultural interests across the region were significant, and accounted for a majority of the estimated $2.2 million worth of losses reported.

The long-lived tornado that developed in south-central Borden County crossed into Howard County east of County Road 41. The tornado's damage path narrowed as it moved over a hay field northeast of Luther. Three hundred round bales of hay, weighing 2,000 pounds each, were shredded by the tornadic winds. All of the hay bales were destroyed and the individual straws of hay served as small missiles, stripping mesquite trees of their bark in a thicket to the west. The tornado crossed County Road 41 about two miles south of the Howard and Borden County line. Chunks of asphalt, some up to six inches in diameter, were removed from the road's surface and deposited in an adjacent field. A 250 yard wide swath was cut through mesquite filled range land west of the road. Large mesquite trees were reduced to stumps that only stood a few feet tall, and were partially debarked. A railroad boxcar that was being used for storage was destroyed one mile west of County Road 41. The boxcar broke into three large pieces as it initially bounced along the earth, leaving large craters in the ground, and then was lofted. The three pieces were displaced a mile to the southwest from the boxcar's original location, near the end of the damage path.A National Weather Service damage survey team concluded that a significant rating (F2) was warranted based on the magnitude of tree and vegetation damage, and the lofting and displacement of the railroad boxcar. The tornadoes total path length across Borden and Howard Counties was nine miles, with a maximum path width of three quarters of a mile in south-central Borden County.

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down. One was issued for the county at another hour that day.

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 Storm Prediction Center had this point in a General Thunderstorms Risk. The outlook in force was issued at 22:15 UTC.

14 more were confirmed in the United States that day.

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.
