Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

Area forecast discussion, Jul 9, 6:24 PM CDT, 1 hour 29 minutes before
Area Forecast Discussion National Weather Service SAN ANGELO TX 624 PM CDT SAT JUL 9 2016 .AVIATION... /00Z TAFS/ A complex of thunderstorms was located over north Texas, and moving slowly west. A few of the storms may move into the eastern Big Country during the next few hours. Will start with VCSH at the KABI terminal and keep an eye on the approaching convection. Otherwise, expect mainly VFR conditions at the terminals during the next 24 hours. && .PREV DISCUSSION... /issued 355 PM CDT SAT JUL 9 2016/ SHORT TERM... (Today and Tonight) Storms earlier today have dissipated across west central Texas. However...stronger convection has formed farther east near the Dallas area. This convection is sending outflow boundaries toward the eastern Big Country. These boundaries may be a focus for a few storms late this afternoon and evening. Therefore, have continued with a slight chance of precip for the Big Country through midnight. Otherwise, hot weather will continue with overnight lows in the upper 70s and a high Sunday near 100 for most areas. 08 LONG TERM... (Sunday night through Saturday) Subtropical ridging will continue to suppress most shower and thunderstorm activity next week. While there is remote chance of a storm in the Northern Big Country or extreme western Concho Valley, potential is too low to include in the forecast. Persistence forecast to continue with highs in the upper 90s and lows in the mid 70s. && .PRELIMINARY POINT TEMPS/POPS...
