    Areas affected...Eastern Georgia...far southern South Carolina...and
    northern Florida

    Concerning...Tornado Watch 51...52...

    Valid 161331Z - 161500Z

    The severe weather threat for Tornado Watch 51, 52 continues.

    SUMMARY...Damaging wind and tornado threat to continue through the
    morning.

    DISCUSSION...A line of storms with embedded supercells continues to
    move east across the Southeast. Instability is mostly weak (250-500
    J/kg MLCAPE) ahead of this line with slightly better instability
    across north Florida where upper 60s dewpoints are present. This
    line of storms has now moved well ahead of the synoptic cold front.
    Therefore, given the weakening forcing, the strongest storms will
    likely be in north Florida this morning. However, very strong
    low-level shear is present ahead of the entire line of storms with
    over 400 m2/s2 0-1km SRH per CLX VWP where a 60 knot low-level jet
    is present. Given the strong low-level shear, damaging wind gusts
    and brief tornadoes will be possible through the morning despite the
    relatively weak instability and forcing.

    Areas affected...Eastern GA into parts of SC and north FL

    Concerning...Tornado Watch 50...

    Valid 121250Z - 121415Z

    The severe weather threat for Tornado Watch 50 continues.

    SUMMARY...The wind-damage and brief tornado threat may continue
    eastward through the morning.

    DISCUSSION...Some decrease in convective vigor has been noted with
    the long-lived QLCS moving across parts of east GA and FL Panhandle.
    However, low-level rotation continues to occasionally be noted along
    portions of the line, especially across parts of
    east-central/southeast GA, where an evolution to more of a
    semi-discrete mode has occurred. Modest downstream destabilization
    and ascent attendant to an approaching mid/upper-level shortwave
    trough may help to sustain organized convection through the morning,
    with some wind-damage and brief-tornado threat spreading into parts
    of SC and southeast GA.

    Lightning activity has diminished with the southern portion of the
    line approaching north FL, but strong low-level flow may continue to
    support at least a localized damaging-wind threat through the
    morning. Parts of north FL will be monitored for an uptick in
    convective intensity later today, due to potential for somewhat
    stronger diurnal destabilization in this area.
