In summary, a significant round of severe thunderstorms affected parts of west Texas during the afternoon and evening of the 11th. At least two supercell storms produced giant hail and one strong tornado over the region.A supercell thunderstorm tracked across Terrell County in the west Texas Lower Trans Pecos region during the late afternoon hours. Multiple reports of large hail including two different instances of tennis ball sized stones were received as this storm tracked east along U.S. Highway 90 between Sanderson and Dryden.A second area of convection erupted over the eastern Permian Basin by late afternoon and continued into the evening hours. A severe storm associated with this activity produced half-dollar size hail in the Westbrook community. An isolated classic supercell evolved from this complex of storms and took on a distinctly deviant southeastward storm motion. This storm took on radar characteristics consistent with a classic tornadic supercell. Hail up to the size of golfballs was observed southeast of Colorado City as the storm evolved into its tornadic phase. A long-lived significant tornado tracked across mainly rural areas of Mitchell County just after sunset. The tornado resulted in three injuries when it crossed State Route 208 and blew a vehicle off of the highway. Severe rear flank downdraft winds also resulted in widespread wind damage south of the tornado's path.

A second severe thunderstorm developed near Westbrook and resulted in numerous reports of large hail up to the size of golfballs along a broad swath from the city of Westbrook to along State Route 208 south of Colorado City. This storm evolved into a right moving classic supercell as it tracked southeast across the central parts of Mitchell County.

Thunderstorm Wind in MITCHELL, TEXAS

Location: COLORADO CITY
Magnitude: 65 EG

Crop damage: 0
Reported by: NWS STORM SURVEY

A broad swath of severe thunderstorm winds resulted in up to forty downed power and utility poles over southeastern Mitchell County. A National Weather Service damage survey concluded that these winds were associated with the storm's occlusion and precluded tornadogenisis. These rear flank downdraft winds snapped poles along State Route 208 and in rural areas east of the highway to the county line.

A National Weather Service damage survey team concluded that a significant tornado struck rural areas of southeastern Mitchell County during the evening of the 11th. The team examined a damage path marked by shredded vegetation (mostly mesquite trees),  downed utility poles, agricultural fences, and a complex of destroyed mobile homes that extended over ten miles in a continuous horseshoe shaped path that crossed State Route 208 twenty miles south-southeast of Colorado City.The tornado developed seventeen miles south-southeast of Colorado City around 2028 CST. Damage indicates the tornado's motion was initially toward the southeast then east as it crossed the heavily traveled State Route 208. Two Texas Tech University students traveling north on 208 (south of the tornado's path) watched as a Ford Expedition drove into the tornadic circulation. The large sports utility vehicle was blown 100 yards off of the highway. Evidence supports the vehicle was rolled a considerable distance by the tornadic winds, but it is unclear whether it became airborne. Three motorists were transferred to local hospitals. One person sustained serious injuries that included a broken back.A detailed damage path analysis and corresponding radar data suggest that the tornado then tracked very slowly east a few miles before curving to the northeast. Similar curved damage paths (turning left of the tornado's original motion) are commonly observed when well-developed tornadoes enter the dissipation stage. The tornado proved to remain very dangerous, however, as eight mobile homes were destroyed by the tornado near the end of its life cycle twenty miles southeast of Colorado City. The light weight and unanchored structures were blown over and shredded by the dissipation stage tornadic winds. The trailers were arranged in a complex and were used to provide shelter for groups of hunters that frequent the ranch property. They were not occupied when the tornado struck.
