    Areas affected...South Carolina into far eastern Georgia

    Concerning...Severe Thunderstorm Watch 459...

    Valid 260007Z - 260200Z

    The severe weather threat for Severe Thunderstorm Watch 459
    continues.

    SUMMARY...An loosely organized MCS will continue to pose a damaging
    wind threat for the next several hours into southern South Carolina
    and far eastern Georgia.

    DISCUSSION...Regional radar imagery has shown an uptick in
    convection as two clusters begin to merge across central SC. The confluence/merging zone of the two outflow boundaries will locally
    enhance low-level ascent, and will likely result in a corridor of
    very strong convection over the next hour or so. Correspondingly,
    there will likely be a downstream corridor where severe/damaging
    wind gusts and/or surging outflow will be more likely owing to
    enhanced water-loading from the stronger convection. Away from this
    corridor, damaging wind gusts will remain likely as the cold-pool
    driven MCS continues to propagate to the south/southwest. Assessment
    of latest surface observations and high-res guidance suggests that
    the MCS will likely propagate along and east of a weak surface
    confluence zone/buoyancy gradient into eastern GA over the next 2-3
    hours.
