    Mesoscale Discussion 1632
    NWS Storm Prediction Center Norman OK
    0530 PM CST Wed Nov 07 2018

    Areas affected...southeast Georgia

    Concerning...Severe potential...Watch unlikely

    Valid 072330Z - 080100Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Isolated damaging wind and brief tornado threat appears to
    have peaked with bowing segment moving through southern GA.
    Intensities are expected to begin a gradual decrease after 00Z.

    DISCUSSION...Organized line of storms with a bowing segment, comma
    head and embedded meso-vortices over south central GA continues east
    at around 40-45 kt. VWP data indicate a local enhancement to the
    wind profiles associated with the attendant MCV compared to model
    data. This activity will continue to pose a threat for isolated
    damaging wind and a brief tornado during the next hour. However,
    overall intensities are expected to decrease after 00Z due to a
    combination of nocturnal cooling as well as the influence of an area
    of showers and storms immediately downstream of the line. A brief
    spike in intensities might occur as the line merges with individual
    storms, but an eventual overall decrease is expected due to the
    stabilizing influence of the downstream area of rain/convection.
