    Areas affected...eastern TX Panhandle into western and central OK

    Concerning...Severe Thunderstorm Watch 463...

    Valid 090635Z - 090800Z

    The severe weather threat for Severe Thunderstorm Watch 463
    continues.

    SUMMARY...Thunderstorm gusts to 45-65 mph remain possible across the
    eastern TX Panhandle into western OK the next couple of hours.

    DISCUSSION...An organized line of convection is developing
    south/southeast at around 40-45 kt. The western flank of convection
    over the eastern TX Panhandle is on the northern fringe of a 25-30
    kt southerly low-level jet, while the eastern edge of the line, now
    spreading into western/central OK, is a bit more removed from the
    influence of the low-level jet. This is evident in a somewhat better
    organized bowing segment over the eastern TX Panhandle. This may
    focus the better risk for severe gusts in a corridor near the
    western OK/TX Panhandle border over the next 1-2 hours.=20

    Strong to severe convection should be maintained the next several
    hours as storms move into an environment with 1000-2000 J/kg MUCAPE
    and 35+ kt effective shear magnitudes. Some eastward expansion of WW
    463 may be needed into parts of central OK depending on trends over
    the next hour or so as convection nears the eastern edge of the
    ongoing severe thunderstorm watch.
