    Areas affected...portions of west Texas

    Concerning...Severe Thunderstorm Watch 187...

    Valid 181007Z - 181100Z

    The severe weather threat for Severe Thunderstorm Watch 187
    continues.

    SUMMARY...A cluster of storms over west Texas will continue to
    weaken early this morning.

    DISCUSSION...The cluster of storms between Midland and San Angelo
    has shown signs of weakening over the past 30-60 minutes. Convection
    is moving into an area of increasing MLCIN. The downstream airmass
    also has been modified by earlier outflow and dewpoints are
    currently in the mid to upper 50s. As a result, convection is likely
    now elevated and recent observed wind gusts from regional West Texas
    Mesonet data indicate gusts generally less than 20-30 mph. A
    continued weakening trend is expected and additional downstream
    watches are not anticipated.
