| Brief Description: The same thunderstorm that spawned a brief touchdown in McCulloch County produced a second tornado south of Richland Springs. A hunting cabin, two trailer homes, 2 barns, and 3 vehicles were destroyed. Several rounds of thunderstorms developed across West Central Texas on the morning and afternoon of the 12th. The first round of storms brought dime to golf ball size hail to parts of the Northern Edwards Plateau, Concho Valley, and the Heartland. A second round of storms that developed during the early afternoon produced a supercell across the southern Heartland. This storm dropped a tornado south of Brady in Southern McCulloch County, as well as hail up the size of golf balls in the town of Brady itself. As the supercell moved into San Saba County, a second tornado would touch down. This tornado had an 8 mile long path and was 100 yards wide, passing 8 miles south of Richland Springs. Although each tornado would produce damage, no injuries or deaths were reported. | |||||||||||

| Brief Description: A large multiple-vortex tornado ripped through eastern Mason County during the late afternoon hours. The slow moving tornado first touched down near the Llano River 9 miles northwest of Loyal Valley and then travelled a 7-mile long path, finally dissipating 5 miles north of Loyal Valley. This tornado, whose width would reach three-quarters of a mile wide at times, caused widespread devastation. Two homes were completely destroyed, with debris scattered over great distances. Large pieces of a pick-up truck were located three-quarters of a mile away from the house where it had been left. Tragically, one person was killed and 5 others were injured when that same house was destroyed. The people had sought refuge in a car in a stone garage, but as the tornado tore across the garage, debris smashed through the car, killing one man and injuring the remaining occupants. Sixteen other houses were damaged, along with additional barns and outbuildings. Numerous head of cattle and deer were also killed as the tornado passed. When the tornado crossed Farm-to-Market Road 152, a stretch of asphalt 720 feet wide was ripped off of the road surface. M75PH A series of supercell thunderstorms ripped across the Heartland and Northwest Hill Country on the afternoon of the 11th. Three tornadoes would touch down, including a devastating F4 tornado north of Loyal Valley in eastern Mason County. One person was killed and 6 others injured as the three-quarters of a mile tornado tracked a 7 mile long path. | |||||||||||
