The severe weather threat for Tornado Watch 227 continues.

SUMMARY...Potential for the development of at least a couple of
intense supercells posing a risk for large hail and tornadoes is
likely to increase through 10 PM-Midnight CDT.  A new tornado watch
will be needed.

DISCUSSION...Although attempts at deep convective development
persist along the dryline, and east of the dryline to the northwest
of Del Rio, relatively warm/dry air in the lower/mid-troposphere has
still contributed to at least some suppression.  The strong westerly
shear, and continued westward retreat of the dryline toward the
Guadalupe and Davis Mountains, also have likely inhibited
development.

However, it does appear that thunderstorm initiation may be
increasingly underway near the intersection of the dryline and
stalled surface front near Wink TX.  And potential for intensifying
thunderstorm development is likely to increase considerably further
across the Pecos Valley toward the Del Rio TX vicinity through mid
to late evening.  Low-level moisture characterized by lower to mid
60s surface dew points is advecting along/south of the Edwards
Plateau, toward the Pecos Valley, as a short wave trough pivots
northeastward toward the region.

As mid-level height falls spread across the region coincident with
the low-level moistening and destabilization, which may included
CAPE increasing to 2000-3000 J/kg, the development of at least a
couple of intense supercells appears increasingly likely through
03-06Z.
