    Areas affected...Parts of the TX Permian Basin/Edwards Plateau

    Concerning...Tornado Watch 229...

    Valid 060733Z - 060900Z

    The severe weather threat for Tornado Watch 229 continues.

    SUMMARY...Tornadoes remain possible near/south of the warm front.
    Otherwise, a threat for large hail and localized severe gusts will
    continue.

    DISCUSSION...Extensive convection is ongoing early this morning
    across parts of the TX Permian Basin and Edwards Plateau. While the
    mode has become complex, a few supercells have persisted, with a
    recent report of 2.5 inch hail in Crane County, TX. Convection may
    continue to increase in coverage overnight, in response to an
    eastward-moving mid/upper-level cyclone over the Southwest and
    related strong low-level jet.=20

    Moderate to strong instability and very favorable deep-layer shear
    will continue to support supercell potential overnight, though some
    continued clustering of storms is possible, especially along an
    eastward moving cold front. Large to very large hail and localized
    severe gusts will continue to be a threat overnight with the
    strongest storms.=20

    The environment remains conditionally favorable for tornadoes
    near/south of a northwest-to-southeast oriented warm front, with
    substantial low-level SRH continuing to be noted in the KDFX VWP.
    Thus far, storms have tended to quickly move to the cool side of the
    front and become elevated. However, it remains possible that ongoing
    developing convection west of Del Rio could evolve into a supercell
    that would pose a tornado threat in addition to the hail/wind
    potential. Storms near the intersection of the warm front and
    eastward-moving cold front/outflow could also pose some embedded
    tornado potential.=20

    With some severe threat likely to persist beyond the 4 AM CDT
    expiration time of WW 229, local watch extension and/or new watch
    issuance will be possible later this morning.
