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
NATIONAL WEATHER SERVICE LUBBOCK TX
245 PM CDT TUE MAY 31 2005

.SHORT TERM...
MID LEVEL 60-70KT JET STREAK COMING OUT OF NEW MEXICO LIFTING THE
AIRMASS ACROSS PANHANDLE DRAMATICALLY LATE THIS AFTERNOON. LOW LEVEL
SOUTHEAST WINDS HAVE BEEN STEADY OR INCREASING INTO AN AREA OF
DEVELOPING STRONG/SEVERE STORMS WITH LAPS-INDICATED HELICITY VALUES
GREATER THAN 75 AND CAPES GREATER THAN 2500 J/KG. ANOTHER REGION WE
HAVE BEEN WATCHING IS TRIPLE POINT ALONG DRY LINE OVER SOUTHEASTERN
NEW MEXICO TO VICINITY SOUTHWESTERN SOUTH PLAINS WHERE IMPRESSIVE
CAPES EXTEND AND HELICITY CURRENTLY APPROACHING 100 FROM THE SOUTH.
FSL ACARS DISPLAY STILL INDICATES 110+ KT JET AROUND 210 MB ARCING
OUT OF SOUTHERN NEW MEXICO AND INTO PERMIAN BASIN...AND MAY YET COME
INTO PLAY AIDING LIFT AS COLD FRONT SLIPS SOUTH ACROSS THE SOUTH
PLAINS THIS EVENING. STILL ALSO PLENTY EVIDENCE OF LEFT-OVER
BOUNDARIES LYING NORTHWEST TO SOUTHEAST ACROSS THE REGION. ALL
INDICATIONS THEREFORE SUPPORT THE POTENTIAL FOR ROTATING HEAVY
PRECIPITATION SUPERCELLS. SPC ISSUED TORNADO WATCH ALL ZONES AND WE
HAVE THUS INCREASED COVERAGE OF STORMS AND MENTION OF SEVERE WITH
HEAVY RAIN. EXPECT AT LEAST ONE DOMINANT CONVECTIVE SYSTEM TO EMERGE
EARLY LATER TONIGHT AND MOVE SOUTHEAST...BUT CANNOT RULE OUT MORE
STORMS AND A SERIES OF CONVECTIVE SYSTEMS LINGERING LATE TONIGHT
FROM ORIGINS FURTHER NORTHWEST THIS AFTERNOON OVER THE NEW MEXICO
HIGHLANDS.

UPPER TROUGH EXPECTED TO FINALLY TRANSLATE FAR ENOUGH EAST TOMORROW
TO SUPPORT DECREASED CHANCES OF STORMS WEDNESDAY. FEW CHANGES TO
PREVIOUS GRIDS FOR TOMORROW.   MCQUEEN

.LONG TERM...
LARGE NEARLY STATIONARY TROF DEVELOPS ACROSS THE PACIFIC NORTHWEST
WITH SEVERAL SHTWVS ROTATING AROUND IT THRU THE CENTRAL ROCKIES AND
NORTHERN PLAINS. ANOTHER SHTWV TROF WILL BE MOVING THRU THE BROAD SW
FLOW FROM SOUTH OF CALIFORNIA INTO SRN NM AND ACROSS WTX ON FRI.
BRIEF SHTWV RIDGING ACROSS THE AREA ON WED AND EARLY THU WILL GIVE
WAY QUICKLY AND THIS TROF SHOULD BRING INCREASING LIFT SPREADING
ACROSS THE SPLNS THU NIGHT INTO FRI...ONGOING CHC POPS THESE PERIODS
LOOK GOOD. INCREASING HEIGHTS AND THICKNESS AND ADVANCING EML WILL
ARGUE FOR A MORE CAPPED ENVIRONMENT SAT AND SUN...HOWEVER WITH
INCREASED SFC HEATING AND PLENTIFUL MOISTURE...WILL RETAIN LOW POPS
FOR POSSIBILITIES OF AFTN AND EVE TSTMS BUSTING THRU THE CAP.

QUESTIONS REMAIN REGARDING WHETHER OR NOT WE CAN RETAIN MOISTURE
ACROSS THE WESTERN COUNTIES INTO THE WEEKEND AS THE SW FLOW
INCREASES OR IF THE DRYLINE WILL DIURNALLY MIX EASTWARD TO THE
CENTRAL COUNTIES AS INDICATED BY GUIDANCE. STILL LEERY OF A STRONG
EASTWARD PUSH AT THIS TIME AND HAVE RETAINED POPS
AREAWIDE...ALTHOUGH HAVE TRENDED BACK A BIT ACROSS THE WEST. BY
MONDAY...NEARLY ZONAL FLOW MAY BE STRONG ENOUGH TO SHUNT DEEPER
MOISTURE AND ASSOC PRECIP CHCS EAST FOR A FEW DAYS BEFORE FLOW AGAIN
BECOMES MORE AMPLIFIED AS UPR LOW REMAINS ACROSS THE NW U.S.

MADE ONLY MINOR CHANGES TO ONGOING FCST BEYOND WED. DID UP HIGH
TEMPS A FEW DEGREES ON THU AS GUIDANCE COMES IN WARMER.
