    Mesoscale Discussion 2354

    Areas affected...portions of southeast Georgia into the northern
    Florida Peninsula

    Concerning...Severe potential...Watch unlikely

    Valid 101746Z - 101915Z

    Probability of Watch Issuance...20 percent

    SUMMARY...A few damaging gusts are possible with wet downbursts
    within the stronger storms this afternoon. The severe threat should
    be isolated, with a WW issuance not expected.

    DISCUSSION...A somewhat organized line of multicells and short
    linear segments have developed with the primary confluence band
    pendant from Isaias' remnants, which is progressing eastward toward
    a destabilizing airmass. Adequate insolation is supporting surface
    temperatures reaching 90 F amid upper 70s F dewpoints, contributing
    to 2000-2500 J/kg MLCAPE. Despite the magnitude of buoyancy present,
    mid-level lapse rates are poor (e.g. around 5.5 C/km per 12Z
    regional observed soundings), with instability confined to tall but
    thin profiles. Furthermore, vertical wind shear is modest, comprised
    of 25-35 kts of effective bulk shear, whose vectors are roughly
    parallel to the confluence boundary.

    Given veered, nearly unidirectional wind profiles, the tornado
    threat should remain quite limited and brief. Given these factors,
    the current thinking is that wet downbursts with the stronger storms
    may produce a few damaging gusts. Still, this threat is also brief
    and localized, so a WW issuance is not anticipated.
