    Mesoscale Discussion 1585

    Areas affected...much of South Carolina into portions of southern
    North Carolina and far eastern Georgia

    Concerning...Severe potential...Watch possible

    Valid 111657Z - 111830Z

    Probability of Watch Issuance...60 percent

    SUMMARY...Scattered thunderstorms will evolve east-southeastward
    through this afternoon and evening, bringing a threat for damaging
    wind gusts to portions of the Carolina Piedmont and Coastal Plain.

    DISCUSSION...Aided by forcing for ascent from a remnant MCV embedded
    within deep-layer westerly flow (around 30 kts of westerly mid-level
    flow sampled by the CLT TDWR VAD) currently analyzed across the
    central Appalachians, widely scattered convection has developed from
    eastern Georgia into central/northwestern South Carolina as of 1655
    UTC. Expectation is for this convection to develop into one or more
    clusters before progressing east-southeastward toward the Atlantic
    Coast through this evening. Ahead of these storms, temperatures have
    climbed into the low-90s, with additional heating expected through
    the afternoon. This will support moderate buoyancy of 2000-2500+
    J/kg MLCAPE when coupled with the moist low-level air mass
    (dewpoints in the low-to-mid 70s) across the region.

    While temperatures are not expected to climb as high as yesterday,
    steepening low-level lapse rates, high PW (2+ inches), and modestly
    stronger mid-level flow will facilitate a risk for damaging wind
    gusts (largely within the 45-55 mph range but locally 55-65 mph).
    The greatest severe potential is expected to develop across portions
    of central South Carolina, where the best overlap of conditions
    favorable for damaging wind gusts should exist. A Severe
    Thunderstorm Watch may be needed to cover this potential within the
    next 1-2 hours.
