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, 9.2 hours before the alert went out and 84 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 NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX 221 PM CDT MON JUN 11 2012 .DISCUSSION... HOT TEMPERATURES AGAIN PREVAILED ACROSS SOUTHEAST NEW MEXICO AND WEST TEXAS THIS AFTERNOON...ALTHOUGH A COLD FRONT WAS MAKING INROADS INTO THE NORTHERN CWA. THIS FRONT WILL MAKE THE TEMPERATURE FORECAST DIFFICULT THE NEXT COUPLE OF DAYS...AND ALONG WITH THE NORTHERN PERIPHERY OF AN UPPER RIDGE OVER THE AREA...THE PRECIPITATION FORECAST WILL BE QUITE THE BEAR TOO. A FEW STORMS MAY DEVELOP/PERSIST THIS EVENING ALONG THE DRYLINE OVER THE EASTERN FRINGE OF THE CWA...AND ALONG THE STALLED FRONTAL BOUNDARY OVER THE SOUTHEASTERN NEW MEXICO PLAINS...NORTHERN PERMIAN BASIN AND WESTERN LOW ROLLING PLAINS. ANY STORMS THAT DEVELOP OVER THE WESTERN LOW ROLLING PLAINS OR LOWER TRANS PECOS COULD BE SEVERE AS MID LEVEL LAPSE RATES OF 8 TO 9 C/KM COMBINE WITH SBCAPE OF 1000 TO 2000 J/KG...IN ADDITION TO 0 TO 6 KM SHEAR AROUND 30KT. IT WILL BE HOT AGAIN TUESDAY...BUT NOT QUITE AS BAD OVER NORTHERN PORTIONS OF THE AREA ALONG AND BEHIND THE FRONT. NOT ONLY WILL LOW LEVEL MOISTURE INCREASE OVER THE AREA TUESDAY AS LOW LEVEL WINDS WILL BE EAST OR SOUTHEAST...BUT MID AND UPPER LEVEL SUBTROPICAL MOISTURE WILL SPREAD NORTHEASTWARD OVER THE REGION. AS A WEAK SHORTWAVE TROUGH MOVES OVER NEW MEXICO AND INTO THE AREA...EXPECT THE HIGHER TERRAIN OF NEW MEXICO AND WEST TEXAS...AND THE FRONTAL BOUNDARY...TO BECOME FOCI FOR THUNDERSTORM DEVELOPMENT TUESDAY AFTERNOON. SOME OF THE STORMS COULD BE SEVERE AS CAPE VALUES WILL BE 1500 TO 2500 J/KG AND MID LEVEL LAPSE RATES 8 TO 9 C/KM ACROSS THE FRONTAL BOUNDARY WHILE BULK SHEAR WILL INCREASE TO 40 TO 50KT. STILL THINK STORMS WILL BECOME MORE WIDESPREAD...EITHER OVER THE HIGHER TERRAIN OF NEW MEXICO OR OVER NORTHERN PORTIONS OF THE CWA TUESDAY EVENING...THEN CONGLOMERATE INTO A MESOSCALE CONVECTIVE SYSTEM TUESDAY NIGHT AS A LOW LEVEL JET STRENGTHENS OVER THE PERMIAN BASIN. HAVE KEPT A CHANCE OF STORMS GOING IN THE FORECAST AND INTRODUCED SEVERE WORDING ALSO. LARGE HAIL...DAMAGING WINDS AND HEAVY RAINFALL WILL BE THE PRIMARY THREATS. NEAR TO ABOVE NORMAL TEMPERATURES WILL PERSIST THROUGH THE REST OF THE WEEK...AS WILL RAIN CHANCES. THE HIGHER TERRAIN OF SOUTHWEST TEXAS WILL BE THE FAVORED AREA FOR CONVECTION THROUGH THE WEEK AS A STEADY FEED OF LOW LEVEL MOISTURE CONTINUES ON EAST TO SOUTHEASTERLY LOW LEVEL FLOW. ALOFT...UPPER LEVEL MOISTURE WILL CONTINUE TO STREAM OVER THE AREA DUE TO WESTERLY TO SOUTHWESTERLY FLOW. ALTHOUGH TEMPERATURES WILL NOT BE QUITE AS HOT...THERE WILL STILL BE PLENTY OF HEATING FOR AN UNSTABLE AIRMASS EACH AFTERNOON AND EVENING. A BROAD UA TROUGH WILL FORM OVER THE SOUTHWEST CONUS BY LATE WEEK WITH THE DOWNSTREAM SOUTHWESTERLY FLOW ALOFT PROPAGATING ADDITIONAL SHORTWAVE TROUGHS OVER THE AREA TO INSTIGATE ADDITIONAL CONVECTION. && .PRELIMINARY POINT TEMPS/POPS...
