    Areas affected...Texas Panhandle

    Concerning...Severe Thunderstorm Watch 174...

    Valid 260604Z - 260800Z

    The severe weather threat for Severe Thunderstorm Watch 174
    continues.

    SUMMARY...An isolated severe threat will likely continue for a
    couple more hours from the the Texas Panhandle eastward into eastern
    New Mexico. Large hail and severe gusts will be the primary threats.

    DISCUSSION...Latest mosaic radar imagery shows a somewhat large
    convective cluster from eastern New Mexico extending eastward into
    the southwestern and central Texas Panhandle. These storms are
    located along the northern edge of an unstable airmass, where the
    RAP is analyzing MLCAPE in the 1000 to 2000 J/kg range. The storms
    are being supported by the instability, along with warm advection
    associated with a 30 to 40 knot low to mid-level jet over west
    Texas. RAP forecast soundings at 06Z in the southwestern Texas
    Panhandle have 0-6 km shear near 40 knots with directional shear in
    the lowest 2 kilometers. This shear environment will likely be
    favorable for isolated supercells with a large hail threat. The
    greatest potential for large hail is expected from the southwestern
    Texas Panhandle into eastern New Mexico where the where the
    combination of instability, shear and steep lapse rates appears to
    be maximized. In addition, supercells could produce isolated severe
    gusts.
