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 10, 10:01 PM CDT, 28 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FORT WORTH TX
1001 PM CDT MON MAY 10 2010

.UPDATE...
CANCELLED TORNADO WATCH FOR MONTAGUE...WISE AND COUNTIES TO THE
SOUTHWEST. 84

&&

.AVIATION...
WEAK THUNDERSTORMS NEAR POSSUM KINGDOM MOVING DUE
EAST TOWARDS METROPLEX TAF SITES. CAP REMAINS IN PLACE ACROSS THE
METROPLEX...AS SEEN IN FWD AND AIRCRAFT SOUNDINGS. HAVE TIMED
STORMS INTO AREA AFTER 02Z (9 PM) AND HAVE AMENDED THE METROPLEX
TAFS TO SHOW VCTS...AS WEAKENING STORMS MOVE INTO THE VICINITY. 84

&&

.PREV UPDATE...
.UPDATE...
UPDATE TO EXTENDED TORNADO WATCH INTO
LAMAR...FANNIN...GRAYON...AND DENTON COUNTIES. STORMS ALONG RED
RIVER AND SOUTHERN MONTAGUE COUNTIES SHOWING SOME WEAK ROTATION SO
THREAT CONTINUES THIS EVENING. 84

&&

.PREV DISCUSSION... /ISSUED 341 PM CDT MON MAY 10 2010/
SURFACE DRYLINE CURRENTLY EXTENDS FROM EXTREME WESTERN OKLAHOMA
TO NEAR VERNON TO NEAR BIG SPRING. CONVECTION HAS INITIATED IN
NORTHERN OKLAHOMA WHERE THE CAP HAS BEEN MUCH WEAKER. SCATTERED CU
HAVE DEVELOPED WEST OF THE CWA AND IS INDICATIVE OF FORCING AND
THE UVVS WILL CONTINUE TO TRY TO BREAK THE CAP AS THE DRYLINE
PROGRESSES EASTWARD.

THE 18Z SPECIAL KFWD RAOB ACTUALLY INDICATED A STRONGER EML THAN
THE 12Z SOUNDING AND CURRENT SOUNDINGS FROM AIRCRAFT DATA INDICATE
THE CAP IS CONTINUING TO STRENGTHEN. GIVEN THE STRENGTH OF THE
CAP...THINK MOST AREAS OF NORTH TEXAS SHOULD BE HARD PRESSED TO
SEE ANY CONVECTION THIS EVENING. A FEW RUNS OF THE RUC AND OTHER
HIGH RESOLUTION MODELS HAVE BROKEN THE CAP AND INDICATE ISOLATED
CONVECTION. HOWEVER...THE MODELS HAVE BEEN TOO BULLISH ON THE
MOISTURE RETURN SOUTH OF THE WARM FRONT AND HAVE BEEN WEAKENING
THE CAP AS THE AFTERNOON PROGRESSES. OBVIOUSLY IF THE CU TO OUR
WEST INITIATES INTO CONVECTION...THE ATMOSPHERE WILL BE MORE THAN
ABLE TO SUPPORT SEVERE STORMS. SBCAPE VALUES ARE GREATER THAN 3000
J/KG WITH 0-6KM SHEAR GREATER THAN 50 KNOTS. STORMS THAT DEVELOP
THEREFORE SHOULD QUICKLY BECOME SEVERE WITH LARGE HAIL AND
DAMAGING WINDS THE MAIN THREATS...BUT CANT RULE OUT ISOLATED
TORNADOES. THE MOST LIKELY AREAS TO SEE CONVECTION WILL BE IN THE
NORTHWESTERN ZONES OR RED RIVER COUNTIES AND WOULD LIKELY BE
CLIPPED BY STORMS MOVING TO THE NORTHEAST/EAST. WILL CARRY 20 POPS
WITH SEVERE MENTIONED IN THE ZONES FOR AREAS NORTH OF AN EASTLAND
TO SHERMAN LINE. WILL ALSO CARRY A 10 POP WITH WEATHER MENTIONED
IN THE ZONES NORTH OF A GOLDTHWAITE TO DALLAS TO PARIS LINE LATE
THIS EVENING WITH ALL POPS TRANSITIONING EAST OVERNIGHT.

THE DRYLINE WILL RETREAT SLIGHTLY OVERNIGHT AND THEN WILL MOVE
EAST AND APPROACH THE WESTERN ZONES OF NORTH TEXAS TOMORROW
AFTERNOON. THERE WILL BE LITTLE IN THE WAY OF FORCING TOMORROW
AFTERNOON AND WILL ONLY MENTION 10 POPS WITH ISOLATED THUNDER IN
THE AFTERNOON AND EVENING. ONCE AGAIN...IF THUNDERSTORMS DO
DEVELOP THEY WILL LIKELY BECOME SEVERE.

RAIN CHANCES WILL END FOR A COUPLE OF DAYS BEFORE RETURNING AGAIN
THURSDAY THROUGH SATURDAY. A COLD FRONT WILL APPROACH THE AREA
THURSDAY AND THE BOUNDARY WILL THEN LINGER ACROSS THE AREA FOR A
COUPLE OF DAYS. THIS WILL PROVIDE A FOCUS FOR SHOWERS AND
THUNDERSTORMS AND WILL CONTINUE WITH THE CHANCE POPS ACROSS THE
CWA.    85/NH
