The radar

The Midland/Odessa radar (KMAF), 46 km from the middle of the area, began a volume at 23:46 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

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.

The nearest sounding before it

Midland Regional, TX (KMAF), launched 12:00Z, 11.8 hours before the alert went out and 45 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Area forecast discussion, Jul 30, 6:09 PM CDT, 38 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
609 PM CDT TUE JUL 30 2013

.DISCUSSION...
SEE AVIATION DISCUSSION BELOW.

&&

.AVIATION...
STORMS WILL REMAIN NEAR PEQ/INK UNTIL AROUND 00Z-01Z OTHERWISE
STORMS WILL BE S OF OTHER TAF SITES AND THE DETERMINATION AS TO
WHETHER TSTMS WILL BE BRIEFLY INCLUDED THERE WILL BE BASED ON
RADAR JUST BEFORE ISSUANCE. OTHERWISE NO SIG WX EXPECTED THRU THE
NIGHT WITH VFR.

&&

.PREV DISCUSSION... /ISSUED 120 PM CDT TUE JUL 30 2013/

DISCUSSION...

AN UPPER RIDGE CONTINUES TO EXPAND OVER THE REGION TODAY WITH
SURFACE TEMPERATURES TRENDING 2 TO 4 DEGREES HIGHER IN MOST
LOCATIONS THAN YESTERDAY AS OF 30/18Z.  THERE IS STILL PLENTY OF
MOISTURE IN THE ATMOSPHERE, NOT ONLY IN THE MID AND UPPER LEVELS,
BUT AT THE SURFACE AS VERIFIED BY STEPPING OUTDOORS.  A WEAK FRONTAL
BOUNDARY HAS EASED INTO SOUTHEAST NEW MEXICO WITH AN ATTENDANT
SURFACE LOW SETTLING OVER THE UPPER TRANS PECOS AND NORTHERN PERMIAN
BASIN.  VISIBLE SATELLITE IMAGERY INDICATED A MESOSCALE CONVECTIVE
VORTEX IN THE VICINITY OF REEVES AND JEFF DAVIS COUNTIES EARLIER,
BUT THIS FEATURE IS NOT DISCERNIBLE ATTM.  THE SHORTWAVE TROUGH OVER
THE AREA YESTERDAY HAS MOVED INTO CENTRAL TEXAS, BUT THERE APPEARS
TO BE ANOTHER NEAR THE BIG BEND REGION.  THINK WE WILL SEE SCATTERED
CONVECTION FROM THE DAVIS MOUNTAINS, SOUTHWARD THROUGH THE BIG BEND
REGION LATER THIS AFTERNOON AND EVENING AS INSTABILITY INCREASES
WITH FURTHER HEATING OF THE HIGHER TERRAIN, THEN INTERACTS WITH THE
SAID MID LEVEL FEATURE NEAR THE BIG BEND.  ALSO, CONVECTION IS
POSSIBLE, JUST NOT LIKELY, OVER MUCH OF THE REST OF THE AREA DUE TO
THE PLENTIFUL MOISTURE AND MENTIONED SURFACE LOW AND FRONT.  ANY
STORMS THAT DEVELOP WILL BE CAPABLE OF HEAVY RAINFALL AND GUSTY
WINDS DUE TO A SLIGHTLY DRIER, HOTTER SUBCLOUD LAYER.

THE WEAK FRONTAL BOUNDARY WILL STAY OVER SOUTHEAST NEW MEXICO AND
THE NORTHERN PERMIAN BASIN TONIGHT AND WEDNESDAY BEFORE RETREATING
OUT OF THE AREA.  ISOLATED STORMS COULD DEVELOP ALONG IT BOTH
TONIGHT AND WEDNESDAY, BUT AGAIN, CHANCES ARE NOT GREAT.  WILL BE
MAGNANIMOUS AND INCLUDE A SLIGHT CHANCE OF THUNDERSTORMS OVER
SOUTHEAST NEW MEXICO WEDNESDAY AS MORE THAN ONE MODEL SEEMS TO
BELIEVE THERE WILL BE ENOUGH CONVERGENCE AND INSTABILITY FOR THIS TO
BE WORTHWHILE.  AFTER WEDNESDAY, THE UPPER RIDGE TAKES MORE FIRM
CONTROL OF THE WEATHER AND HAVE PRETTY MUCH SQUELCHED POPS AREAWIDE
THROUGH THE REST OF THE EXTENDED.  AS PROMISED, HIGH TEMPERATURES
WILL ROUTINELY RISE TO AROUND THE CENTURY MARK, EXCEPT FOR A LITTLE
COOLER IN THE MOUNTAINS.  LATER SHIFTS WILL STILL HAVE TO MONITOR
THE HEAT FOR A HEAT ADVISORY IN THE NEXT FEW DAYS.  IT APPEARS THE
MOST LIKELY LOCATIONS WILL BE ALONG THE RIO GRANDE.
