    Areas affected...Northern Georgia

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

    Valid 022205Z - 030000Z

    Probability of Watch Issuance...40 percent

    SUMMARY...The potential for strong to severe downburst winds may
    increase over the next couple of hours if storm clustering can
    occur. While confidence is limited, watch issuance may be needed.

    DISCUSSION...Over the past half hour, GOES imagery has depicted an
    uptick in cumulus depth and intensity of ongoing convection across
    northern GA and adjacent portions of NC and SC. Some of this
    activity appears to be driven by residual outflow from prior
    convection, hinting that low-level forcing for ascent may be
    sufficient for further intensification as storms move further into
    northern GA. Here, temperatures have warmed into the mid/upper 90s
    with dewpoint depressions generally around 20-25 F and low-level
    lapse rates between 8 to 8.5 C/km. This environment is very
    favorable for intense downbursts capable of producing strong/severe
    wind gusts. The potential for such winds may increase as storms
    continue to propagate west/southwest into this environment. The wind
    threat may become somewhat more widespread if clustering can occur,
    which may necessitate watch issuance. However, given the relatively
    late onset of deeper convection in the diurnal heating cycle, it
    remains somewhat unclear how prolonged/prolific the wind threat will
    be. Nonetheless, trends will continue to be monitored.
