| 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. | |||||||||||
