A second supercell thunderstorm initiated along the dryline over eastern Hale and western Floyd County. This storm produced large hail and a family of tornadoes as it tracked northeastward. The most significant tornado to impact the South Plains region on the 28th developed as this storm tracked over the Caprock Canyons State Park area north of Quitaque (Briscoe County). This tornado damaged at least three structures as it cut a nearly twenty mile path across eastern Briscoe County, northwestern Hall County, and southern Donley County.

Many storm chasers observed a large multiple vortex tornado that developed north of Quitaque shortly after 17:30 CST. The tornado initially touched down immediately north of Texas Highway 256, and tracked northeastward across the Prairie Dog Town Fork of the Red River. The tornado cut a twelve mile long path through the mesquite thickets of eastern Briscoe County, however, it continued across northwestern Hall County and into extreme southern Donley County before ending at 17:09 CST. The total path length was nearly twenty miles in length. |Despite the rural nature of the area, a few structures sustained significant damage. A trailer house was destroyed about five miles south of the river. The trailer was vacant when the tornado struck, but frequently served to house deer hunters. A single-story residence also was impacted by the tornado near Antelope Flat. The roof was totally blown off of the home. A forty by twenty-four foot barn used to store all-terrain vehicles also was destroyed at the homestead. At least two wind mills were additionally destroyed. The destruction of the trailer house, the complete loss of the roof to the home, and the destruction of the large barn all support an EF2 rating. No injuries were reported.

The long-lived tornado that impacted eastern Briscoe County moved through rural areas of northwestern Hall County, just west and northwest of Brice. Although the tornado was large and had a history of causing significant damage, no man-made structures were affected in Hall County. The tornado was roping out when it crossed the Hall and Donley County line west of Texas Highway 70 at 17:05 CST.

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 Moderate Risk, with a 0.15 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 21:01 UTC.

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.
