The radar

The Albuquerque radar (KABX), 38 km from the middle of the area, began a volume at 20:32 UTC, the scan nearest the moment this went out.

The nearest sounding before it

Santa Teresa, NM (KEPZ), launched 12:00Z, 8.5 hours before the alert went out and 328 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.

Areas affected...parts of central New Mexico

Concerning...Severe potential...Watch unlikely 

Valid 072029Z - 072300Z

Probability of Watch Issuance...5 percent

SUMMARY...The evolution of one or two supercells posing a risk for
large hail and locally damaging wind gusts appears possible near and
southwest through south of Albuquerque by 4-6 PM MDT.

DISCUSSION...Deepening convective development is ongoing across the
higher elevations of western into central New Mexico.  This is
likely occurring as lingering inhibition is overcome by orographic
forcing for ascent, weak low-level warm advection, and continued
boundary-layer warming.

South-southwesterly deep-layer mean flow is a relatively modest
20-25 kt, but vertical shear has become strong, particularly across
the Albuquerque vicinity of central New Mexico, where easterly
near-surface flow is trending southeasterly.  This generally
coincides with strongest ongoing boundary-layer destabilization near
and southwest through south of Albuquerque, which appears to include
mixed-layer CAPE locally up to 1000 J/kg.  

Through 22-00Z, it appears that the environment will become
increasingly conducive to scattered intensifying thunderstorm
development, possibly including the evolution of 1 or 2 sustained
supercell structures.  The stronger cells may tend to take on an
increasing eastward propagation, accompanied by the risk for large
hail and locally strong surface gusts into early evening.
