    Areas affected...central and eastern FL Panhandle...far southwest GA

    Concerning...Severe Thunderstorm Watch 174...

    Valid 272034Z - 272200Z

    The severe weather threat for Severe Thunderstorm Watch 174
    continues.

    SUMMARY...Scattered damaging gusts and perhaps a tornado will remain
    possible through 5-6pm EDT.

    DISCUSSION...Radar mosaic shows a north-northeast to south-southwest
    oriented band of a thunderstorms move east across the northeast Gulf
    of Mexico and central portions of the FL Panhandle late this
    afternoon. Surface streamline analysis indicates weak easterly flow
    across the central portion of the FL Panhandle during the past
    couple of hours. Surface conditions ahead of the band of storms
    have temperatures in the lower to mid 70s with dewpoints in the
    lower 70s. A long-lived supercell has continued east-northeast
    across the Panhandle with all hazards being exhibited via radar
    during the past couple of hours. The band of storms and associated
    convection on its leading edge is beginning to encroach on the
    supercell with the potential for a tornado becoming more uncertain
    with time. Nonetheless, a pronounced surge in the line supported by
    strong deep-layer shear (effective shear 60 kt) will favor swaths of
    damaging gusts as a weak mesolow begins to develop centered with
    thunderstorms near Washington/Calhoun counties. Complex storm-scale interactions may continue to occur with both damaging gusts and
    perhaps a brief mesovortex tornado possible as as the band moves
    east during the next 1-2 hours.
