    Areas affected...from the Laredo area eastward toward the middle to
    upper Texas Coast

    Concerning...Severe Thunderstorm Watch 233...

    Valid 200450Z - 200615Z

    The severe weather threat for Severe Thunderstorm Watch 233
    continues.

    SUMMARY...Isolated wind gusts over 50 kt remain possible across
    parts of southern into southeast Texas, within the broader zone of
    30-40 kt outflow.

    DISCUSSION...Within a broad W-E zone of thunderstorms, a few wind
    gusts over 50 kt have been measured, most recently at Kerrville TX
    with 56 kt. While most of the outflow as produced gusts of 30-40 kt,
    several larger/more organized storm clusters exist near intersecting
    outflow boundaries. The air mass remains quite moist, with modest
    southerly winds just above the surface aiding inflow (elevated above
    the outflow in some cases).=20

    At this time it appears the overall severe risk will remain isolated
    across the entire region, with most gusts below 50 kt. However,
    trends will continue to be monitored as the system as a whole
    develops southeastward tonight.
