    Areas affected...portions of the Southeast

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

    Valid 131907Z - 132130Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Widely scattered thunderstorms will bring a localized risk
    for damaging downburst winds. Watch issuance is not anticipated.

    DISCUSSION...Latest surface observations depict a hot, humid air
    mass in place across the southeastern U.S., with temperatures in the mid-to-upper 90s F and dewpoints in the upper 60s noted along the
    Atlantic Coast. Surface convergence along the sea breeze and a of a
    roughly west-east oriented stationary boundary is supporting
    isolated thunderstorm development as of 19 UTC, with additional
    agitated cumulus noted on visible satellite imagery. As thunderstorm
    coverage expands through the afternoon (particularly where low-level convergence maximizes over northeastern SC and southeastern NC),
    steep low-level lapse rates and high PWAT contents (1.75-2.0") will
    favor the potential for isolated strong to locally damaging
    downburst winds. An instance or two of small hail may also accompany
    the most robust cores that develop along the sea breeze. A lack of
    greater effective shear will limit overall storm organization and
    longevity, thus precluding a greater severe risk. Given this, watch
    issuance is not anticipated.
