    Concerning...Tornado Watch 227...

    Valid 060127Z - 060330Z

    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.
