    Areas affected...Parts of central/southern GA into the FL Panhandle
    and a small part of western SC

    Concerning...Tornado Watch 49...

    Valid 121035Z - 121200Z

    The severe weather threat for Tornado Watch 49 continues.

    SUMMARY...The threat for damaging winds and embedded brief tornadoes
    may continue to spread eastward through dawn. Downstream watch
    issuance is possible.

    DISCUSSION...A QLCS is moving across parts of GA and FL Panhandle as
    of 1030 UTC. Several embedded circulations and possible brief
    tornadoes have been noted over the last 1-2 hours, especially where
    discrete cells earlier merged into the line across far southeast AL
    into southwest GA. Downstream of this QLCS, increasing low-level
    flow has been noted from the KJGX and KVAX VWPs. This strengthening
    flow will continue to aid in low-level moisture transport
    along/ahead of the line. The gradually increasing downstream
    moisture and buoyancy, combined with ascent attendant to a
    fast-moving mid/upper-level shortwave trough, will help to sustain
    organized convection through dawn as the QLCS moves
    east-northeastward.=20

    The strongest surface pressure falls at 10 UTC were noted in advance
    of the north-south oriented portion of the line moving across west-central/southwest GA, with strong pressure rises noted in the
    wake of this section of the line. A corridor of somewhat greater
    wind-damage potential may accompany this portion of the line as it
    moves across central GA. Otherwise, at least locally damaging wind
    will remain possible along the length of the QLCS, with strong
    low-level flow/shear supporting embedded brief-tornado potential.=20

    The magnitude of destabilization into parts of eastern GA and SC
    remains uncertain, though if the QLCS remains organized, some
    potential for wind damage and brief tornadoes may eventually spread
    east of locally expanded WW 49. Downstream watch issuance is
    possible, depending on short-term observational trends.
