    Areas affected...portions of the northern Gulf Coast and Southeast

    Concerning...Severe potential...Watch unlikely=20

    Valid 251723Z - 251930Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Scattered to numerous thunderstorms this afternoon may
    pose a sporadic risk for strong wind gusts. Little in the way of
    storm organization is expected.

    DISCUSSION...As of 1715 UTC, visible and radar imagery showed a
    broad area of thunderstorms ongoing over the central Gulf Coast
    states associated with a remnant MCV. Widespread anvil debris
    remains apparent and should limit destabilization over much of MS,
    western AL and the western FL Panhandle. To the east of the MCV and
    clouds, strong diurnal heating is rapidly destabilizing the air mass
    across eastern AL, northern FL and much of GA and into SC. Despite
    the poor mid-level lapse rates, 70s F surface dewpoints are
    supporting ~2000 J/kg of MLCAPE. Sufficient for periodic stronger
    updrafts, scattered to numerous thunderstorms are expected this
    afternoon and evening as convective temperatures in the mid to upper
    80s F are breached.

    While some low and mid-level flow enhancement is occurring closer to
    the MCV farther west, little in the way of vertical shear is present
    over much of the Southeast (EBWD <25 kts). This suggests storm
    organization will be quite limited, with a predominant pulse/multi
    cell storm mode. High PWAT content (greater than 2 inches) may
    support a few stronger downdrafts capable of sporadic damaging
    gusts.

    Storm coverage should increase this afternoon, along the eastern
    edge of the remnant cloud shield and differential heating zone in
    AL/GA, and in association with sea breeze convection in northern FL.
    A few stronger clusters may evolve as outflows consolidate. However,
    the lack of border upper air support should limit a sustained
    severe threat and a watch appears unlikely.
