    Areas affected...the Texas Panhandle

    Concerning...Severe Thunderstorm Watch 177...

    Valid 162312Z - 170045Z

    The severe weather threat for Severe Thunderstorm Watch 177

    SUMMARY...Threat for mainly isolated large hail will persist through
    01Z over the TX Panhandle, after which the primary threat may
    transition to damaging wind.

    DISCUSSION...Scattered thunderstorms continue along a nearly
    stationary outflow boundary across southern portions of the TX
    Panhandle as well as along the outflow boundary-dryline intersection
    and a short distance southward along the dryline. Storms remain
    discrete in character, suggesting large hail remains the primary
    short-term threat. The atmosphere is moderately unstable, and a
    strengthening southerly low-level jet this evening will augment
    mesoscale forcing along the outflow boundary. Storms might become
    numerous enough for individual outflows to merge, eventually
    supporting the potential for a forward propagating MCS. Should this
    evolution occur, the primary threat will transition to damaging wind
    by 01Z as storms develop southeast.
