    Areas affected...Eastern Georgia into southern South Carolina

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

    Valid 101800Z - 102000Z

    Probability of Watch Issuance...5 percent

    SUMMARY...A corridor of regionally higher wind damage potential may
    be emerging as thunderstorm clusters spread east into a very buoyant
    air mass. A weak kinematic environment will limit the overall severe
    threat, watch issuance is not anticipated.

    DISCUSSION...Radar imagery from KJGX in central GA shows
    consolidating outflow boundaries beginning to emerge as multicell
    thunderstorms begin to slowly grow upscale. Additionally, latest
    GOES IR imagery shows cooling cloud top temperatures indicative of
    convective intensification. Over the next few hours, one or two more robust/consolidated convective clusters may emerge as cold pools
    continue to amalgamate and as storms migrate into a regional
    buoyancy maximum (MLCAPE recently analyzed as high as 3000 J/kg) and
    towards the GA/SC coast. Regional VWPs continue to sample very weak
    (15 knots or less) westerly flow and poor deep-layer wind shear.
    This will modulate storm intensity/organization and limit the
    overall severe threat; however, the thermodynamic environment is
    supportive of damaging downburst winds. As storm coverage increases
    with the potential emergence of one or more clusters, the
    probability of damaging gusts should increase as well.
