    Areas affected...parts of northern Georgia into adjacent Upstate
    South Carolina

    Concerning...Severe potential...Watch unlikely

    Valid 041842Z - 042115Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Evolving supercell structures with potential to produce a
    tornado or two appear possible across the Piedmont of northeastern
    Georgia and adjacent Upstate South Carolina by 4-6 PM EST. It is
    still not certain that this will require a severe weather watch, but
    trends are being monitored.

    DISCUSSION...A lingering belt of moderate to strong southeasterly to
    southerly low-level flow (around 850 mb) across much of western and
    northern Georgia is in the process of weakening and shifting north-northeastward based on latest Rapid Refresh output. By
    20-22Z, strongest flow is forecast to become confined to the
    Piedmont into higher terrain of northeastern Georgia and adjacent
    Upstate South Carolina, but may still include speeds on the order of
    30-35+ kt supporting sizable clockwise-curved low-level hodographs,
    within an associated low-level warm advection zone.

    Rapid 2-hourly surface pressure falls in excess of 2 mb are already
    evident in 17Z surface observation across much of the Georgia into
    South Carolina Piedmont, where associated ageostrophic accelerations
    may contribute to increasing low-level convergence and further
    moistening of boundary-layer dew points through the mid/upper 60s F.
    Despite generally weak lower/mid-tropospheric lapse rates, coupled
    with some boundary warming within breaks in the overcast,
    near-surface destabilization may support intensifying convective
    development, as negatively-tilted mid-level troughing slowly spreads into/across the southern Appalachians. This may include a few
    evolving supercell structures with potential to produce a couple of
    tornadoes. However, this threat still appears conditioned on the
    evolution of near-surface thermoynamic profiles becoming conducive
    to at least weak surface-based buoyancy.
