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.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
642 PM CDT SAT JUN 1 2013

.UPDATE...
HAVE UPDATED THE PRODUCTS FOR ISSUANCE OF SEVERE THUNDERSTORM
WATCH 270.

&&

.DISCUSSION...
VERY HIGH INSTABILITY AND AND STRONG SHEAR ALONG AND SOUTH OF A
SLOW MOVING FRONT WILL CAUSE THUNDERSTORMS...SOME SEVERE WITH
LARGE HAIL AND DAMAGING WINDS...TO DEVELOP THIS AFTERNOON AND
EVENING. CANNOT RULE OUT A BRIEF TORNADO SPIN UP SHOULD A STORM
BECOME ANCHORED ALONG THE FRONT WHERE ENHANCED LOW LEVE VORTICITY
NEAR WILL BE FAVORED BUT THE CHANCES ARE DIMINISHED DUE TO THE
OVERALL POOR ENVIRONMENT THUS THE GREATER CONCERN FOR HAIL AND
WINDS. COOLING TEMPERATURES WILL ALLOW INSTABILITY TO DECREASE
AFTER MIDNIGHT.

HENNIG

&&

.AVIATION...
THUNDERSTORMS WILL DEVELOP ALONG A COLD FRONT NEAR I-10 WHICH MAY
ONLY AFFECT FST...AND EVEN THEN STORM CHANCES ARE TOO LOW TO
MENTION IN TAF. MVFR CIGS MAY DEVELOP BEHIND THE FRONT AS A STRONG
RETURN FLOW LIFTS MOIST AIR UP ALONG THE PECOS RIVER VALLEY. THESE
LOWER CONDITIONS WILL ONLY LAST A FEW HOURS BEFORE SCATTERING OUT
AND LIFTING TO VFR LEVELS.

DISCUSSION...

WV IMAGERY SHOWS THE UPPER TROUGH OVER IA AND EJECTING INTO THE
GREAT LAKES REGION...LEAVING DRY...ZONAL FLOW ALOFT OVER WEST
TEXAS/SE NM.  AT THE SFC...AN ASSOCIATED COLD FRONT HAS PROVIDED
MUCH COOLER AFTERNOON TEMPS TO THE AREA THAN THE PAST FEW DAYS.  SFC
ANALYSIS SHOWS THE COLD FRONT EXTENDING FROM
KPG1-K6R6-KSTI-KABI...WHILE A LINE OF TCU CAN BE SEEN ON VIS SAT
IMAGERY DEVELOPING SOUTHWESTWARD ALONG THIS FEATURE.  MESOSCALE
ANALYSIS SHOWS THE CAP OVER THE LWR TRANS PECOS JUST ABOUT
GONE...AND SBCAPES THERE IN THE BALLPARK OF 2500 J/KG.  CONVECTION
DEVELOPING AFTER 00Z ALONG THE FRONT IS STILL EXPECTED...W/STEEP
MID-LVL LR/S SUGGESTING MAINLY A HAIL THREAT.

SFC FLOW WILL BEGIN VEERING OVERNIGHT...W/RETURN FLOW QUICKLY
ADVECTING DEWPOINTS OF 50F OR BETTER W-NW WELL INTO NM BY 18Z
SUNDAY.  MODELS THEN BRING A SHORTWAVE E INTO THE
REGION...INITIATING CONVECTION ALONG THE MTNS AS SOON AS LATE
MORNING.  AGAIN...MODELS DIFFER SLIGHTLY ON TIMING/PLACEMENT OF BEST
INSTABILITY...BUT FORECAST SOUNDINGS YIELD AFTERNOON CAPS IN EXCESS
OF 3000 J/KG...MID-LVL LR/S OVER 7C/KM...AND INVERTED V SIGNATURES.
W-NW FLOW ALOFT WILL RESULT IN EFFECTIVE BULK SHEAR OF 35KTS OR
BETTER...SO A FEW SVR STORMS WILL BE POSSIBLE...W/HAIL AND WINDS
BEING THE MAIN CONCERNS.  FOR NOW...WE/LL KEEP EMPHASIZING THE SVR
THREAT IN THE HWO...AND LEAVING IT OUT OF THE GRIDS.  FOCUS OF
CONVECTION SHOULD MOVE N AND E OVERNIGHT W/THE SHORTWAVE.  MODELS
THEN BRING A WEAKER SHORTWAVE THRU THE FLOW MONDAY.  THE ECMWF IS
WETTEST...WHILE THE GFS IS MAINLY DRY...SO WE/LL KEEP LOW ORDER POPS
IN FOR THEN.

MONDAY WILL SEE A RETURN TO TEMPS NEAR TRIPLE DIGITS AS THE UPPER
RIDGE RE-ESTABLISHES ITSELF IN MEXICO.  TEMPS FOR THIS FORECAST
SHOULD PEAK TUE/WED...BEFORE THE RIDGE GETS DAMPENED SW INTO THE
PACIFIC BY AN UPPER TROUGH DIVING INTO THE UPPER CONUS...AND MODELS
STILL BACKDOORING A FRONT INTO THE AREA WEDNESDAY NIGHT.  THIS WILL
LEAVE MOST OF THE FA IN A PLEASANT MID TO UPPER 90S FOR THE DURATION
OF THE FORECAST.  EXTENDED REMAINS DRY.
