    Mesoscale Discussion 0879
    NWS Storm Prediction Center Norman OK
    0644 PM CDT Mon Jun 25 2018

    Areas affected...Portions of southern and eastern GA into
    south-central SC

    Concerning...Severe potential...Watch unlikely

    Valid 252344Z - 260145Z

    Probability of Watch Issuance...5 percent

    SUMMARY...A threat for locally strong to severe damaging wind gusts
    exists across southwest through east-central Georgia and adjacent
    south-central South Carolina (in vicinity of Aiken County) through
    this evening for the next 2-3 hours (until 9-10 PM EDT).

    DISCUSSION...Trends in mosaic radar imagery showed two convectively
    enhanced composite outflow boundaries expected to merge over
    southwest through east-central GA and adjacent south-central SC
    between 00-01Z (8-9 PM EDT). Additional storms are expected to form
    through mid evening as these two boundaries and other convective
    outflow boundaries merge within an environment of residual moderate
    buoyancy. The 40-60-mile-wide corridor encompassing the discussion
    area also had DCAPE of 1000-1400 J/kg. This combined with
    precipitable water exceeding 1.8 inches indicates the potential for
    a threat for locally strong to severe wind gusts, similar to the
    gust that occurred at KEZM of 52 kt at 2315Z.
