    Areas affected...western Tennessee and southwestern Kentucky

    Concerning...Tornado Watch 8...

    Valid 160009Z - 160145Z

    The severe weather threat for Tornado Watch 8 continues.

    SUMMARY...Tornado threat continues within WW008. Threat will
    continue downstream into portions of Middle Tennessee and Western
    Kentucky.

    DISCUSSION...A broken line of thunderstorms has shown an uptick in
    intensity over the last hour across the Arkansas/Tennessee border.
    Line embedded supercells are observed, with activity ahead of the
    main line also exhibiting rotation. The low level jet, with axis
    currently from central LA to middle TN/southern KY, is progged to
    continue strengthening through the evening, with low level shear
    becoming more favorable. This strong southerly flow has also ushered
    in deeper moisture and a more favorable air mass across western
    Tennessee, steadily approaching southern Kentucky.

    Given the progress of the main line, maintenance of individual cells
    ahead of the line will be difficult. However, deep layer shear of
    50-55 kts will continue to support line embedded mesocyclones and
    potential for damaging wind and tornadoes. This threat is spreading
    eastward and will likely necessitate a downstream watch into
    southern Kentucky soon.
