    Areas affected...portions of central Texas

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

    Valid 270006Z - 270130Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Potential for strong to occasionally damaging wind gusts
    and isolated large hail will continue for another 1-2 hours.
    Downstream watch issuance is unlikely, however.

    DISCUSSION...Latest radar imagery depicts the continued eastward
    propagation of a convective cluster across portions of central Texas
    as of 0000 UTC. The environment ahead of this activity remains
    modestly unstable (1000-1500 J/kg MLCAPE), but stronger upper-level
    flow and greater effective shear remain displaced farther to the
    south, with only 20-25 kts of effective shear analyzed across the
    discussion area. This is likely inhibiting the overall intensity and organization of this cluster, with radar data from KGRK indicating
    that the system outflow continues to largely precede the ongoing
    convection. Despite this, some potential for strong to occasionally
    damaging wind gusts may continue for another couple of hours.
    Isolated large hail may also be possible, particularly with any more
    robust, discrete convection that precedes this cluster. More limited
    mid-level lapse rates (generally less than 7 C/km) and the
    aforementioned modest effective shear should largely limit this
    potential, however. Trends will continue to be monitored, but
    downstream watch issuance is currently unlikely.
