    Areas affected...portions of central/eastern Georgia into central
    South Carolina

    Concerning...Severe Thunderstorm Watch 486...

    Valid 122046Z - 122215Z

    The severe weather threat for Severe Thunderstorm Watch 486
    continues.

    SUMMARY...The potential for damaging wind gusts continues across
    Severe Thunderstorm Watch 486. Some potential for isolated damaging
    gusts may also develop/persist downstream into portions of
    northeastern SC/southeastern NC with time.

    DISCUSSION...Widely scattered thunderstorm activity continues across
    Severe Thunderstorm Watch 486 as of 2045 UTC, with isolated reports
    of damaging wind gusts noted over the past 1-2 hours. Continued
    heating of a moist low-level air mass continues to support
    moderately strong buoyancy (MLCAPE of 2000-2500 J/kg) and steep
    low-level lapse rates. This environment favors the continued
    potential for damaging wind gusts across the Watch area,
    particularly from eastern GA into western SC where low-level lapse
    rates are steeper.

    Latest objective analysis also depicts a zone of steeper low-level
    lapse rates across portions of southeastern NC. Convection evolving
    eastward from northern SC and/or additional thunderstorm development
    across the NC Coastal Plain may pose a risk for isolated damaging
    wind gusts through this evening, but downstream watch issuance
    appears unlikely at this time due to the expectation for this risk
    to remain isolated in nature.
