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

    Concerning...Severe potential...Watch possible

    Valid 101432Z - 101700Z

    Probability of Watch Issuance...40 percent

    SUMMARY...The potential for isolated tornadoes will increase through
    the remainder of the morning into the late afternoon hours. The best
    chance for a tornado in the near-term will be with storms making
    landfall on the SC coastline, where the best low-level moisture and
    instability resides.

    DISCUSSION...Diurnal heating is contributing to gradual
    boundary-layer destabilization within the right-front quadrant of
    Isaias' remnants, which should gradually increase the isolated
    tornado threat through the morning hours. At the moment, the best
    airmass resides over southeast GA (between ongoing convection in SC
    and the primary confluence band across central GA). This
    surface-based airmass encompasses mid to upper 70s F surface
    temperatures and equivalent dewpoints, yielding over 1200 J/kg
    MLCAPE (when modifying the 12Z CHS observed sounding). Supercells
    along the SC coastline are showing more persistent low-level
    rotation, and these are the most likely storms to produce a tornado
    over the next couple of hours.

    Despite impressively enlarged/curved hodographs depicted by regional
    VADs (with over 400 m2/s2 0-3 km SRH noted), much of the inland
    airmass remains relatively stable. Given how stable the airmass is
    inland from the coast, the timing of a Tornado Watch remains
    uncertain. However, a watch issuance will be needed at some point
    once surface-base destabilization becomes more widespread.
