    Areas affected...Atlantic Coast portions of SC and GA into the FL
    Panhandle.

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

    Valid 251915Z - 252115Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Scattered thunderstorms along multiple sea-breeze
    boundaries will support a risk for occasional damaging gusts or
    sporadic hail this afternoon. A WW is not expected.

    DISCUSSION...As of 1915 UTC, regional radar and satellite showed
    scattered to numerous thunderstorms erupting along the Atlantic
    Coasts of GA and SC, extending southward across much of the FL
    Peninsula. Driven largely by diurnal heating and localized
    confluence along typical sea-breeze boundaries, a few stronger multicells/clusters have been noted recently. With little in the way
    of upper-level forcing for ascent, convection has been largely
    unorganized and is expected to remain as such. However, additional
    clustering may support stronger cold pool development with time.
    This could allow for occasional damaging gusts and wet microbursts
    given the high PWATs (~1.8-2 inches) air mass. Sporadic hail is also
    possible with the more intense updrafts given around 2000 J/kg of
    MLCAPE. While occasional damaging gusts and hail are possible, the
    lack of broader upper-level support suggests the severe risk will be transient/isolated. A WW is not expected this afternoon.
