    Areas affected...Texas Panhandle...Western Oklahoma...Far Southern
    Kansas

    Concerning...Severe Thunderstorm Watch 459...

    Valid 072324Z - 080130Z

    The severe weather threat for Severe Thunderstorm Watch 459
    continues.

    SUMMARY...A severe threat is likely to develop eastward into western
    Oklahoma over the next hour. Wind damage and isolated large hail
    will be the primary threats. Weather watch issuance will likely be
    needed across parts of western Oklahoma, and possibly northward into
    far southern Kansas.

    DISCUSSION...A linear MCS is currently ongoing across the Texas
    Panhandle. This line is located near a maximum in instability, where
    the RAP is estimating MLCAPE in the 2000 to 3000 J/kg range. In
    addition, the latest WSR-88D VWP from Amarillo has 0-6 km near 45
    knots with some directional shear in the low-levels. This will
    support a severe threat as the line continues to move eastward this
    evening. The line of severe storms is expected to track along and
    north of a quasi-stationary front extending east-southeastward
    across western and south-central Oklahoma. Damaging wind gusts and
    isolated large hail will be the primary threats. Weather watch
    issuance will be needed across parts of western Oklahoma within the
    hour. The watch could be needed in parts of far southern Kansas if
    the line can develop slightly further to the north.
