    Mesoscale Discussion 0624
    NWS Storm Prediction Center Norman OK
    1055 AM CDT Sat Jun 02 2018

    Areas affected...Southern Georgia...southeastern Alabama...northern
    Florida

    Concerning...Severe potential...Watch likely

    Valid 021555Z - 021700Z

    Probability of Watch Issuance...80 percent

    SUMMARY...Scattered thunderstorms will continue to expand in
    coverage and intensify through the afternoon. Wind damage and
    occasional hail are the main threats. A WW issuance is being
    considered.

    DISCUSSION...Recent radar mosaic and satellite imagery indicate
    increasing convective coverage and intensity - particularly near and
    south of CSG. Objective analyses across this region indicate an
    uncapped and modestly sheared airmass, with surface-based CAPE
    values exceeding exceeding 3000 J/kg. With time, gradual upscale
    growth of the cluster near CSG is expected, along with continue
    development across the region ahead of this cluster.
    Forward-propagating bows and isolated cells will be capable of both
    wind damage and isolated hail instances as storms migrate
    south-southeastward. Given the aforementioned atmospheric factors,
    a WW is being contemplated for portions of the region and may be
    needed around 17Z or so.
