| Brief Description: 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. 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. | |||||||||||

| Brief Description: A quickly moving tornado tore a 10 mile path through southern Taylor County. This tornado hit the community of Tuscola, where it damaged the Jim Ned high school injuring two people. A strong upper level disturbance combined with a strong surface low pressure system moving across West Central Texas produced a significant squall line that moved through the entire San Angelo county warning area. This squall line was accompanied by 60 to 80 MPH winds which produced widespread damage, especially across the Big Country. Embedded within the squall line, were several Supercell thunderstorms which produced nine tornadoes within the San Angelo county warning area. | |||||||||||
