    Areas affected...Portions of the Georgia and Carolina Coast

    Concerning...Severe potential...Watch unlikely

    Valid 241815Z - 242015Z

    Probability of Watch Issuance...5 percent

    SUMMARY...The potential for damaging downburst winds is gradually
    increasing across portions of the Georgia and Carolina coast. This
    threat is expected to remain sufficiently sporadic and transient to
    preclude watch issuance.

    DISCUSSION...Convection has been gradually increasing along the
    NC/SC coast along a weak cold front as temperatures continue to warm
    into the low 90s under partly cloudy skies. Continued ascent along
    the cold front and along a sharpening sea-breeze boundary through
    late afternoon will promote additional thunderstorms in the coming
    hours. Deep-layer wind shear across the region remains very weak
    (per regional VWPs), and will continue to predominantly favor
    pulse-convection and perhaps poorly organized clusters. However,
    filtered daytime heating is contributing to low-level lapse rates on
    the order of 8 C/km through the lowest 1-2 km that may promote
    downdraft accelerations near the ground. Consequently, some
    potential will exist for strong downbursts (featuring max winds of
    40-60 mph) through late afternoon. This potential will be greatest
    where dewpoint depressions can be maximized - namely across far
    eastern GA into southern SC where more limited cloud cover has
    allowed temperatures to warm into the 90s with ~20 F dewpoint
    depressions. Given the isolated and transient nature of the threat,
    watch issuance is not expected.
