Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado 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, May 9, 3:02 PM CDT, 52 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN ANGELO TX
302 PM CDT THU MAY 9 2013

.SHORT TERM...
ATMOSPHERE WAS VERY UNSTABLE WITH WRF SB BASED CAPES OF 3000 J/KG
ACROSS THE BIG COUNTRY AND CONCHO VALLEY...SOUTHWARD TO SONORA
THIS AFTERNOON. SEVERE STORMS WITH HAIL OF 2 INCHES IN DIAMETER
WERE ALREADY REPORTED IN SWEETWATER. A SEVERE THUNDERSTORM WATCH
IS IN EFFECT FOR NEARLY ALL OF WEST CENTRAL TEXAS UNTIL 7 PM. MAIN
THREATS ARE VERY LARGE HAIL AND DAMAGING WINDS. SEVERE
THUNDERSTORMS LIKELY INTO THIS EVENING.

WEAK COLD FRONT MOVING THROUGH THE SOUTHERN TEXAS PANHANDLE THIS
AFTERNOON...WILL MOVE SOUTH INTO THE BIG COUNTRY AFTER 1 AM TONIGHT...AND
ALONG A SAN ANGELO TO SAN SABA LINE 1 PM FRIDAY AFTERNOON. THIS
WILL BE A FOCUS FOR ADDITIONAL THUNDERSTORM DEVELOPMENT. COULD SEE
AN ISOLATED SEVERE THUNDERSTORM AS THE COLD FRONT MOVES
THROUGH...BUT THE BEST CHANCE WILL BE FRIDAY AFTERNOON...WITH WEAK
CONVERGENCE AND SB CAPES OF 2000 J/KG...ALONG AND AHEAD THE COLD
FRONT.

.LONG TERM...
DECREASING RAIN CHANCES FRIDAY NIGHT INTO SATURDAY AS DRIER AIR
MOVES INTO THE REGION FROM THE NORTH. STILL COULD SEE AN ISOLATED
ELEVATED THUNDERSTORM...BUT INSTABILITY IS WEAKER SO DO NOT EXPECT
SEVERE STORMS.

BOTH THE GFS AND EC MODELS DEVELOP A CUT OFF UPPER LOW OVER BAJA
CALIFORNIA...THEN WEAKEN AND SHEAR IT OUT OVER NEW MEXICO AND THE
TEXAS PANHANDLE MONDAY NIGHT INTO WEDNESDAY. BROUGHT A CHANCE OF
SHOWERS AND THUNDERSTORMS DURING THIS TIME PERIOD. WOULD NOT BE
SURPRISED TO SEE A FEW SEVERE STORMS DEVELOP BY TUESDAY
AFTERNOON...AS MOISTURE AND INSTABILITY INCREASE.
