    Mesoscale Discussion 0998
    NWS Storm Prediction Center Norman OK
    0352 PM CDT Tue Jul 03 2018

    Areas affected...Central/Southern Georgia

    Concerning...Severe potential...Watch unlikely

    Valid 032052Z - 032245Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Isolated severe wind gusts will be possible with storms
    moving into a moderately unstable airmass. Organization and coverage
    of storms should remain low. A WW is not anticipated.

    DISCUSSION...Storms that have initiated along the sea-breeze front
    in southeastern South Carolina have moved into a moderately unstable environment with 2000-2500 J/kg of MLCAPE. While deep-layer shear
    has increase somewhat with the approach of a low pressure system to
    the east, values still are meager with only 15-20 per KJGX VAD
    profiles. Forecast soundings and 7.3 micron watery vapor imagery
    indicate relatively dry air in the mid-levels. The strongest storms
    will have downdrafts capable of producing an isolated severe wind
    gust. Given the overall disorganized nature of the storms, a WW is
    not anticipated.
