    Areas affected...central TX

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

    Valid 280837Z - 281000Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Strong gusts and hail are possible with a cluster of
    strong storms moving east over the central TX.

    DISCUSSION...A cluster of storms has intensified to the west of the
    I-35 corridor/greater San Antonio area early this morning. This
    activity is occurring within a moderately unstable airmass amid 40
    kt effective shear magnitudes. Radar trends have shows some
    indication of strong outflow gusts associated with this cluster,
    though KERV only gusted to around 27kt as the core of these stronger
    velocity signatures passed just south of the observation site.
    Nevertheless, some strong gusts and perhaps hail will be possible as
    the cluster approached the I-35 corridor over the next hour or so.
    Given a lack of stronger forcing, and the absence of a low-level
    jet, it is unclear how long this cluster may maintain its current
    intensity. Overall, severe potential should remain limited and a
    watch is not expected.
