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, Apr 26, 4:00 PM CDT, 2 hours 11 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LUBBOCK TX
400 PM CDT SUN APR 26 2009

.SHORT TERM...
NEARLY STATIONARY SFC DRYLINE IS CURRENTLY ALONG A LINE FROM NEAR
CLARENDON TO MATADOR TO SPUR TO JUSTICEBURG.  STORMS FORMED EASIER
ALONG A SURFACE BOUNDARY...NOW EXITING THE CWFA ACROSS THE
SOUTHEAST... HAVE PRODUCED QUARTER SIZE HAIL ACROSS PORTIONS OF KING
COUNTY.  NEW CONVECTION IS NOW GOING UP ALONG THE DRYLINE WHERE
SBCAPE OF 2000-2500 J/KG IS IN PLACE PER RUC MESOANALYSIS.  MAIN CONCERN
CONTINUES TO BE LARGE HAIL WITH THIS ACTIVITY.  GREATEST TORNADO
THREAT APPEARS TO BE EAST OF THE CWFA WHERE WINDS HAVE REMAINED
BACKED.

LATE THIS AFTERNOON INTO THIS EVENING...ADDITIONAL DEVELOPMENT MAY
BE POSSIBLE GENERALLY EAST OF THE CAPROCK ESCARPMENT ALONG THE
DRYLINE IN RESPONSE TO REGION OF UPPER LEVEL LIFT COMING IN FROM ERN
NEW MEXICO.  SURFACE WINDS HAVE BEGUN TO BACK SOMEWHAT IN ADVANCE OF
THIS FEATURE.  LATER TONIGHT...ANOTHER BURST OF UPPER ENERGY MAY
INDUCE ADDITIONAL ANOTHER ROUND OF CONVECTION...AFTER PERHAPS A
BRIEF LULL...PARTICULARLY ACROSS THE NORTHERN HALF OF THE AREA.

ON MONDAY...A FEW STORMS MAY BE POSSIBLE IN THE FAR EASTERN ZONES
ONCE AGAIN AS DRYLINE TIGHTENS ACROSS THE EAST.  STAY TUNED...

&&

.LONG TERM...
NOT MUCH CHANGE MADE TO THE EXTENDED THIS AFTERNOON AS 12Z MODEL
RUNS STILL IN FAIR AGREEMENT THROUGH THE MIDDLE OF THE WEEK...THEN
BEGIN TO DIVERGE TOWARD THE WEEKEND. THE NAM IS STILL THE QUICKEST
WITH THE COLD FRONT MOVING THROUGH THE AREA ON MONDAY...AND TAKES
IT FARTHER SOUTH THAN THE GFS AND ECMWF. IF NAM VERIFIES THAN
PRECIP CHCS WILL BE A BIT LOWER ACROSS THE AREA AND SLOWER TO PICK
BACK UP. IN ANY CASE...PASSAGES OF SOME WEAK SHTWVS TUE/TUE NIGHT
SHOULD GENERATE SHOWER AND TSTM ACTIVITY. INSTABILITY WILL BE
LIMITED EARLY...BUT BY LATE IN THE DAY...WE ANTICIPATE WARMING
ACROSS THE W-SW ZONES TO RESULT IN SOME TSTM POTENTIAL...AND WE
ALSO EXPECT STRONG WAA TO DEVELOP WITH LLJ AFTER SUNSET WHICH
SHOULD RESULT IN EXPANDING TSTM COVERAGE ACROSS THE WHOLE AREA.
DEEP MOISTURE WILL BRING THE POTENTIAL FOR HEAVY RAINFALL TUE
NIGHT/EARLY WED...ESPECIALLY ACROSS THE ROLLING PLAINS. WE EXPECT
IMPROVING CONDITIONS FROM WEST TO EAST DURING THE DAY WED...BUT
BOTH THE GFS AND ECMWF NOW BRING THE NEXT FRONT INTO THE AREA
EARLIER...POSSIBLY ON THU...IN THE WAKE OF A SHTWV MOVING ACROSS
THE NRN PLAINS. THIS MAY LEAD TO COOLER CONDITIONS FRI/SAT WITH
LACK OF A DRYLINE BUT POSSIBLY SOME INCREASED PRECIP POTENTIAL
LATE IN THE PERIOD AS A TROUGH APPROACHES FROM THE WEST...WITH
TIMING AND STRENGTH HIGHLY UNCERTAIN.

&&

.FIRE WEATHER...
CRITICAL FIRE WX CONDITIONS ONGOING THIS AFTERNOON WEST OF
I-27/U.S. 87. THESE CONDITIONS SHOULD GRADUALLY IMPROVE THIS
EVENING AS TEMPS COOL/WINDS DECREASE. VERY DRY CONDITIONS WILL
RETURN ON THE CAPROCK MONDAY AFTERNOON BUT THE WIND SPEEDS ARE
EXPECTED TO REMAIN WELL BELOW CRITICAL LEVELS. A COLD FRONT WILL
MOVE THROUGH THE AREA LATE MONDAY AND TUESDAY BRINGING COOLER AND
MORE MOIST CONDITIONS WITH EASTERLY UPSLOPE WINDS.
