    Mesoscale Discussion 1195

    Areas affected...portions of southeast GA...central and coastal
    SC...and southeast NC

    Concerning...Severe potential...Watch possible=20

    Valid 081409Z - 081615Z

    Probability of Watch Issuance...40 percent

    SUMMARY...Thunderstorm intensity and coverage will gradually
    increase into midday and early afternoon from southeast Georgia into
    southeast North Carolina. Locally strong/damaging gusts will be
    possible.

    DISCUSSION...Isolated thunderstorms are currently ongoing this
    morning across portions of the SC Midlands into central Georgia
    along outflow from overnight convection. While overall weakening has
    occurred during the diurnal minimum that past few hours, these
    outflow and ongoing convection will continue to move into an
    unstable and very moist downstream airmass over the next few hours.=20


    Moderate to strong instability is already in place across southern
    GA into coastal SC, with some further destabilization expected with
    time into far southeast NC. Vertical shear will remain modest,
    around 20-30 kt effective shear magnitudes. But this, along with a
    modest 850 mb low-level jet, will be sufficient for storm
    organization. Steepening low-level lapse rates are expected with
    additional heating, with midlevel lapse rates around 7 C/km are
    evident in RAP forecast soundings and the 12z CHS RAOB. This should
    support isolated strong/damaging gusts and perhaps sporadic hail
    into the afternoon.

    Timing of greater storm coverage/intensification is a bit uncertain,
    but trends are being monitored for possible watch issuance toward
    midday.
