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.

NWS Corpus Christi, TX wrote its last area forecast discussion before this severe thunderstorm warning went out at Mar 19, 11:05 PM CDT, 22 minutes earlier.
Area forecast discussion, Mar 19, 11:05 PM CDT, 22 minutes before
AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE CORPUS CHRISTI TX
1105 PM CDT MON MAR 19 2012
.DISCUSSION...EXTENDED WIND ADVISORY FOR THE COASTAL LOCATIONS
THROUGH THE MORNING HOURS. IN ADDITION...EXTENDED THE SMALL CRAFT
ADVISORY THROUGH THE MID MORNING. FINALLY GETTING SOME CONVECTION
DEVELOPING OVER THE WESTERN LOCATIONS...EXPECTING THE MAIN LINE
OVER THE HILL COUNTRY TO MOVE THROUGH AFTER 06Z AND CONTINUING
THROUGH THE MID MORNING HOURS. HOW FAR SOUTH THE DEVELOPMENT MAY
BE IS THE QUESTION. MODELS PICKING UP ON MOVING A SURFACE LOW OVER
THE WESTERN AREAS TO SHIFT A BIT FURTHER EAST...BRINGING IN DRIER
AIR IN THE MIDLEVELS...INCREASING THE CAP. HOWEVER...ENOUGH
CONVERGENCE MAY BE PRESENT ESPECIALLY OVER THE EASTERN HALF OF THE
CWA...TO ALLOW THE LINE OF STORMS TO MOVE ALL THE WAY TO THE
COAST. EARLY TONIGHT...THE BEST CHANCES OF SEVERE WEATHER WILL
REMAIN OVER THE FAR WEST TO NORTHWESTERN LOCATIONS...WITH BEST
CHANCES OF SEVERE SHIFTING WELL OVER THE NORTHERN TO NORTHEASTERN
LOCATIONS TOWARDS DAYBREAK.
&&
.PREV DISCUSSION... /ISSUED 709 PM CDT MON MAR 19 2012/
DISCUSSION...PLEASE SEE UPDATED 00Z AVIATION DISCUSSION.
AVIATION...CEILINGS WILL LOWER TO MVFR/IFR THROUGH THE NIGHT.
STORMS ARE DEVELOPING OVER SOUTH CENTRAL TEXAS...WITH MORE
DEVELOPMENT EXPECTED TO MOVE IN BEHIND THIS LINE OF STORMS OFF THE
SIERRA MADRE IN MEXICO...POSSIBLY AFFECTING LRD AFTER 03Z. A MORE
ORGANIZED LINE OF STORMS IS EXPECTED TO PUSH THROUGH LATE TONIGHT
THROUGH TUESDAY MORNING...REACHING AREAS FROM ALI-VCT AROUND
06Z...THEN TO CRP BY 10Z. SOME OF THESE STORMS HAVE TO POSSIBILITY
TO BECOME STRONG TO SEVERE WITH STRONG WINDS AND HAIL BEING THE
MAJOR THREAT...WITH BEST CHANCES OF SEVERE OVER AREAS NORTH OF A
COT-ALI-VCT LINE. THE STORMS SHOULD PUSH OUT OF THE AREA BY MID
MORNING THROUGH THE EARLY AFTERNOON...WITH N-NW WINDS DEVELOPING
AND VFR CONDITIONS.
PREV DISCUSSION... /ISSUED 335 PM CDT MON MAR 19 2012/
SHORT TERM (TONIGHT THROUGH TUESDAY NIGHT)...THE MAIN FORECAST
CONCERN FOR TONIGHT WILL BE THE THREAT FOR SEVERE WEATHER ACROSS
SOUTH TEXAS. THE FORECAST AREA REMAINS IN A SLIGHT RISK FROM THE
SPC...WITH THE GREATEST THREAT BEING DAMAGING STRAIGHT LINE WINDS
AND LARGE HAIL. POTENT UPPER LEVEL TROUGH WILL SLOWLY MOVE OUT OF
THE ROCKIES/FOUR CORNERS REGION OVERNIGHT. THIS WILL PUSH A
PACIFIC COLD FRONT ACROSS THE REGION OVERNIGHT INTO EARLY TUESDAY
MORNING. FORECAST MODELS HAVE THE LOW LEVEL JET STRENGTHEN TO 50-60KTS
LATE TONIGHT...HELPING TO FEED LOW LEVEL MOISTURE INTO THIS
SYSTEM. FORECAST MODELS SHOW ISOLATED STORMS TO DEVELOP AROUND 00Z
OUT WEST...AHEAD OF THE FRONT. THESE STORMS COULD BECOME
SUPERCELLULAR AND WILL BE WORTH WATCHING IF THEY INITIATE. A LINE
OF CONVECTION ACROSS THE HILL COUNTRY WILL DEVELOP SOUTHWARD ALONG
THE FRONT AND PUSH THROUGH THE REGION BETWEEN MIDNIGHT AND
SUNRISE. LOCALLY HEAVY RAINFALL WILL ALSO BE POSSIBLE WITH THIS
ACTIVITY WITH ISOLATED RAINFALL AMOUNTS GREATER THAN 2 INCHES.
ACROSS THE FAR SOUTH...LESS INSTABILITY AND A STRONGER CAP WILL
LIMIT THE SEVERE POTENTIAL. DRIER AND COOLER CONDITIONS ARE
EXPECTED IN WAKE OF THE FRONTAL PASSAGE TUESDAY. HOWEVER...SOME
MODELS LINGER MOISTURE AND PRECIPITATION ACROSS THE REGION WITH
THE MAIN UPPER LEVEL LOW STILL EXITING THE REGION. FOR NOW...WILL
END PRECIPITATION FROM WEST TO EAST THROUGH TUESDAY NIGHT.
LONG TERM (WEDNESDAY THROUGH MONDAY)...TEMPERATURES WILL BE THE
MAIN FORECAST CONCERNS THROUGH THE EXTENDED. AT THE BEGINNING OF THE
PERIOD...UPPER LEVEL LOW WILL BE CENTERED OVER NORTH CENTRAL
TEXAS...WITH THE FRONT SETTLING OFF SHORE BY THIS TIME. EXPECT
CHANCES FOR PRECIP TO BE WINDING DOWN FROM WEST TO EAST AS DRIER AIR
FILTERS INTO THE WESTERN PARTS OF THE CWA. HOWEVER...LEFT SOME LOW
END POPS ACROSS THE FAR EASTERN SECTIONS AND PARTS OF THE COASTAL
WATERS WHERE MOISTURE WILL STILL LINGER. UPPER LEVEL LOW WILL PULL
AWAY FROM SOUTH TEXAS WEDNESDAY NIGHT INTO THURSDAY. COOLER TEMPS IN
STORE FOR WEDNESDAY BEHIND DEPARTING SYSTEM WITH LOWER 80S OUT WEST
TO LOWER 70S NEAR THE COAST. GFS/EURO AGREE ON UPPER LEVEL RIDGE
BUILDING INTO THE REGION FROM THE SOUTH THE LATTER HALF OF THE WORK
WEEK...WITH TEMPS REBOUNDING WELL INTO THE 80S INLAND TO MID/UPPER
70S ALONG THE COAST. LITTLE CHANGE TO THE EXTENDED WITH NON
MENTIONABLE POPS AS UPPER RIDGE WILL REMAIN THE DOMINANT FEATURE.
