The radar

The Albuquerque radar (KABX), 65 km from the middle of the area, began a volume at 20:25 UTC, the scan nearest the moment this went out.

The nearest sounding before it

Albuquerq/Krtlnd, NM (KABQ), launched 12:00Z, 8.4 hours before the alert went out and 50 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.

Skew-T log-p

Temperature in red, dew point in green, the mixed-layer parcel dashed.

MESOSCALE DISCUSSION 1021
NWS STORM PREDICTION CENTER NORMAN OK

AREAS AFFECTED...NEW MEXICO

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 262024Z - 262200Z

...THUNDERSTORMS ARE EXPECTED TO INCREASE IN AREAL
COVERAGE/INTENSITY ALONG/WEST OF CONTINENTAL DIVIDE.  WW MAY BE
REQUIRED...

STRONG SFC RIDGE WEDGED AGAINST THE HIGHER TERRAIN OF ERN NM HAS
FORCED BOUNDARY LAYER MOISTURE ACROSS CNTRL INTO PORTIONS OF WRN NM
WHERE ABUNDANT SUNSHINE IS CURRENTLY OBSERVED. RESULTANT
DESTABILIZATION...SBCAPES APPROACHING 2000 J/KG...AND STRONG
BUOYANCY DUE TO STEEP LAPSE RATES HAVE ALLOWED CONVECTION TO DEVELOP
OVER THE SAN MATEO MTNS...AND HIGHER TERRAIN INTO NRN NM. 
SUFFICIENT WNWLY FLOW ALOFT WILL SUPPORT STORM ORGANIZATION AND
POSSIBLE SUPERCELL STRUCTURES. THIS ACTIVITY WILL CONTINUE TO
INCREASE IN INTENSITY AS CONVECTION MOVES TOWARD THE SPINE OF THE
HIGHEST TERRAIN OF CNTRL NM.  THUNDERSTORMS WILL WEAKEN AS THEY
ENCOUNTER COOLER AIRMASS OF ERN NM LATER THIS EVENING. UNTIL
THEN...LARGE HAIL SHOULD BE THE PRIMARY SEVERE THREAT WITH THIS
ACTIVITY.
