    Mesoscale Discussion 0110

    Areas affected...Parts of southeast AL into central/southern GA and
    southern SC

    Concerning...Severe potential...Watch unlikely=20

    Valid 211534Z - 211730Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Some uptick in the localized severe threat is possible
    through the morning into early afternoon.

    DISCUSSION...A small bowing segment with a history of producing
    localized wind damage is moving into west-central GA this morning,
    with other loosely organized convection trailing southwestward into south-central AL. This convection is generally moving along or just
    north of a sharp baroclinic zone draped from southern MS into
    central AL/GA and southern SC. Midlevel lapse rates are generally
    modest at best, but modest diurnal heating and MLCAPE approaching
    1000 J/kg (with a similar magnitude of MUCAPE immediately north of
    the front) should help to sustain deep convection through the
    morning.=20

    Area VWPs depict rather strong deep-layer shear and moderate
    southwesterly low-level flow, which will continue to be favorable
    for occasionally organized storm structures. However, with a
    tendency for the outflow-reinforced cold front to sag southward with
    time and potentially undercut the strongest convection, the
    organized severe threat may remain isolated through the morning.=20

    Locally damaging wind appears to be the most likely short-term
    hazard, though marginal hail cannot be ruled out with the strongest
    embedded updrafts. Low-level shear/SRH is sufficient for some
    brief-tornado threat, though this potential is conditional on
    maintenance of surface-based convection along or ahead of the
    sagging front.
