    Areas affected...Portions of south-central Nebraska

    Concerning...Severe Thunderstorm Watch 395...397...

    Valid 072351Z - 080115Z

    The severe weather threat for Severe Thunderstorm Watch 395, 397
    continues.

    SUMMARY...Large hail, damaging winds, and a tornado or two remain
    possible with thunderstorms tracking south-southeastward across
    south-central Nebraska this evening.

    DISCUSSION...Latest radar data from KLNX indicates several discrete/semi-discrete supercells tracking south-southeastward
    across south-central Nebraska this evening. In particular, one
    longer-lived intense supercell currently over southeastern Custer
    County poses the greatest risk for large hail, damaging winds, and a
    tornado. Downstream of this storm, VWP data shows a large,
    clockwise-curved low-level hodograph (around 200 m2/s2 0-1 km SRH),
    which will support ample streamwise vorticity ingestion, given
    middle 60s dewpoints and moderate surface-based instability. This
    supercell may persist for another 60-90 minutes, with large hail up
    to 2.5 inches, locally damaging gusts up to 75 mph, and a tornado
    possible.

    Trailing supercell development along the outflow boundary will also
    pose a risk for large hail and damaging winds, and a brief tornado
    cannot be ruled out. Farther east over Nance County, a locally
    upscale-growing storm cluster is moving southeast at 30-35 kt, and
    this storm may pose a greater damaging-wind risk, with large hail
    also possible.
