    Areas affected...Portions of south TX

    Concerning...Severe Thunderstorm Watch 232...

    Valid 010750Z - 010915Z

    The severe weather threat for Severe Thunderstorm Watch 232

    SUMMARY...Isolated strong/gusty winds remain possible with a small
    cluster of storms.

    DISCUSSION...Strong velocities at low to mid levels have been noted
    from KDFX over the past 1-2 hours with a small cluster of convection
    moving slowly east-southeastward across south TX. Even though no
    severe wind or damage reports have been received as of 0750Z
    (Cotulla TX/KCOT recently measured a wind gust to 37 kt), isolated
    strong/gusty winds will remain possible in the short term. Stronger
    MLCIN likely exists to the south of this activity per recent
    mesoanalysis estimates, and recent tracking of the cluster suggests
    a more east-southeastward motion. The environment downstream remains
    at least somewhat conducive for surface-based storms, with around
    1000 J/kg of MLCAPE, 35-40 kt of deep-layer shear, and a moist
    low-level airmass present. But, the lack of even more boundary-layer instability may continue tend to limit the threat for severe wind
    gusts to some extent across Severe Thunderstorm Watch 232.
