    Areas affected...northern Texas Panhandle

    Concerning...Severe potential...Watch unlikely=20

    Valid 132351Z - 140145Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Conditional threat for severe wind and large hail this
    evening.

    DISCUSSION...Cumulus continues to deepen across portions the
    northern Texas Panhandle near Amarillo, with a few attempts noted
    further south east of I-27 near Cap Rock. This is occurring along a
    boundary of increasing moisture moving northward from western
    Oklahoma into the TX/OK Panhandles. Overall, forcing for ascent is
    weak aside from the this weak boundary leading to low confidence in thunderstorm development. Given a storm, the very warm and well
    mixed boundary layer and steep low to mid-level lapse rates would be
    conducive to instances of large hail and severe gusts. This threat
    remains too conditional and isolated for watch issuance but trends
    will be monitored.
