    Areas affected...portions of northern Georgia into the Carolina
    Piedmont

    Concerning...Severe potential...Watch unlikely

    Valid 181813Z - 182015Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Widely scattered thunderstorms may bring some potential
    for isolated damaging wind gusts through this evening. Watch
    issuance is not anticipated.

    DISCUSSION...Widely scattered to scattered thunderstorms have begun
    to initiate across portions of the central Appalachians and Carolina
    Piedmont as surface temperatures have risen into the low-90s F amid
    continued insolation. Poor mid-level lapse rates and weak deep-layer
    flow/shear will tend to limit overall convective intensity and
    organization; however, MLCAPE of 1000-2000 J/kg coupled with steep
    low-level lapse rates and PW around 1.75-2.00 inches (as supported
    by a modified 12z GSO observed sounding and current objective
    analysis) are supportive of at least some potential for isolated
    damaging downburst wind gusts (with peak gust magnitudes likely in
    the 45-55 mph range). Locally greater potential may exist across
    portions of central North Carolina where the latest observational
    trends and CAM guidance are suggestive of greater storm coverage.
    Trends will continue to be monitored, but the overall severe threat
    is likely to remain too isolated and limited in magnitude to warrant
    watch issuance.
