    Mesoscale Discussion 1462

    Areas affected...portions of northern Georgia...the western
    Carolinas and eastern Tennessee

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

    Valid 262155Z - 262330Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Ongoing clusters of multi-cell storms will continue to
    pose an isolated risk for locally damaging gusts and small hail into
    this evening. A locally greater risk may occur across north-central
    GA where stronger storms are occurring.

    DISCUSSION...As of 2145 UTC, regional radar/satellite imagery showed
    several clusters of semi-organized multi-cells ongoing from northern
    GA, through the western Carolinas, and into far eastern TN. Over the
    last several hours, reports of locally damaging winds and small hail
    have occurred as these clusters have shifted west/southwest within a
    broad area of moderate to large buoyancy (MLCAPE 2000-3000 J/kg).
    This trend appears likely to continue into early this evening as new
    updraft development/intensification continues on the flanks of these established storm clusters.

    A locally greater severe risk may develop in vicinity of the Atlanta
    Metro over the next couple of hours as a stronger multi-cell cluster
    has emerged. Several downbursts have been noted within this cluster
    as multiple strong updrafts have coalesced. While deep-layer flow
    remains limited, very large buoyancy and strong surging outflow
    could support isolated severe-caliber gusts in the 55-65 mph range
    into early this evening.
