    Areas affected...western Kansas into the Panhandles and northwest
    Oklahoma

    Concerning...Severe Thunderstorm Watch 386...

    Valid 240811Z - 241115Z

    The severe weather threat for Severe Thunderstorm Watch 386
    continues.

    SUMMARY...Potential for localized severe hail or wind gusts exists
    into western Kansas, and extending southeast of the existing watch
    into the northeast Texas Panhandle and far northwest Oklahoma.
    Additional watches are not anticipated at this time.

    DISCUSSION...Outflow associated with earlier severe storms over
    eastern CO is now pushing into southwest KS, and is intersecting a
    northwest to southeast oriented line of elevated storms in a zone of
    theta-e advection associated with southerly 850 mb winds. VWPs from
    AMA to GLD indicate around 15-20 kt out of the south to southeast.

    The primary instability axis stretches from southeast CO into
    northwest OK, and while SBCIN is increasing, elevated instability
    should continue to support areas of new development. New storm cores
    may produce hail briefly, and locally damaging gusts may still
    occur.=20

    At this time it appears the cold pool from southeast CO into
    southwest KS may not be sufficient for significant upscale MCS
    growth. However, there is non-zero potential, and the area
    south/southeast of WW 386 will continue to be monitored this
    morning.
