    Areas affected...Southeast Georgia into far southern South Carolina

    Concerning...Severe Thunderstorm Watch 596...

    Valid 062224Z - 070030Z

    The severe weather threat for Severe Thunderstorm Watch 596
    continues.

    SUMMARY...Damaging winds will remain possible into the evening hours
    as storms approach the Georgia/South Carolina coast; however, this
    threat will likely remain fairly limited. Downstream watch issuance
    is not expected.

    DISCUSSION...Ongoing thunderstorm clusters/lines across central to
    eastern Georgia have largely become outflow dominant over the past
    few hours. With cell motions to the east - orthogonal to the outflow propagation vector - new development along these boundaries is
    uncertain across central GA. Further east, a more easterly cold-pool
    motion is allowing for new cell development within an unstable air
    mass (SBCAPE estimates up to 2000-3000 J/kg). Forecast soundings
    from this region appear favorable for wet downbursts capable of
    damaging winds. The expectation over the next hour is for continued
    cell development along/behind the eastward-moving outflow with the
    potential for sporadic damaging winds. This activity may persist to
    the GA/SC coast, but storm longevity/organization will remain too
    limited to pose a more robust threat. Consequently, downstream watch
    issuance is not anticipated.
