The nearest sounding before it

Midland Regional, TX (KMAF), launched 12:00Z, 11.4 hours before the alert went out and 103 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.

MESOSCALE DISCUSSION 2113
NWS STORM PREDICTION CENTER NORMAN OK

AREAS AFFECTED...FAR WRN TX AND EXTREME SERN NM

CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 

VALID 142324Z - 150030Z

MARGINALLY SEVERE STORMS WILL BE POSSIBLE ACROSS PORTIONS OF FAR WRN
TX AND EXTREME SERN NM DURING THE EVENING HOURS...BUT THE SEVERE
THREAT SHOULD BE TOO ISOLATED FOR A WW ISSUANCE.

SELY BOUNDARY LAYER WINDS HAVE ADVECTED LOWER 60S DEWPOINTS INTO WRN
TX...THOUGH WEAK LAPSE RATES ALOFT WERE RESULTING IN MUCAPES OF ONLY
500-1000 J/KG. STORMS SHOULD INCREASE IN NUMBERS ACROSS SWRN TX
THROUGH THE EVENING AS A JET MAX AND INCREASING DIFFLUENCE ALOFT
SPREADS INTO THE AREA. DEEP LAYER SHEAR AT 40-50 KT WILL BE
FAVORABLE FOR SOME STORMS TO ROTATE AND POSSIBLY PRODUCE 3/4 TO 1
INCH SIZE HAIL. HOWEVER...THE WEAK MID LEVEL LAPSE RATES/INSTABILITY
SUGGEST THE SEVERE THREAT SHOULD REMAIN ISOLATED.
