    Areas affected...Southern Kentucky...Tennessee

    Concerning...Severe potential...Watch possible

    Valid 081250Z - 081515Z

    Probability of Watch Issuance...40 percent

    SUMMARY...An isolated severe threat is expected to continue this
    morning. The stronger storms will have potential for hail, strong
    gusts and a brief tornado. Weather watch issuance may become
    necessary later this morning.

    DISCUSSION...The latest mosaic radar imagery in the Tennessee Valley
    shows numerous thunderstorms along an east-to-west outflow boundary,
    from southern Kentucky into northern Tennessee. To the south of this convection, the RAP has moderate instability in place, with MLCAPE
    generally in the 2000 to 2500 J/kg range. Forecast soundings in
    northern Tennessee this morning suggest the activity is
    surface-based. WSR-88D VWPs along and near the outflow boundary have
    0-6 km shear in the 45 to 50 knot range, which will continue to be
    sufficient for supercells and bowing line segments. Wind damage and
    hail the primary threats. However, VWPs also have 0-1 km shear in
    the 20 to 25 knot range near this feature, suggesting that a brief
    tornado will be possible with embedded supercells.
