    Mesoscale Discussion 2353
    NWS Storm Prediction Center Norman OK
    1200 PM CDT Sat Oct 10 2026

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

    Concerning...Severe potential...Watch possible

    Valid 101700Z - 101830Z

    Probability of Watch Issuance...60 percent

    SUMMARY...The threat for isolated tornadoes continues to gradually
    increase through the early afternoon. A Tornado Watch issuance may
    be needed pending strengthening storm trends.

    DISCUSSION...The warm sector within the right-front quadrant of
    Isaias' remnants continues to destabilize, with insolation and
    low-level warm-air advection contributing to low 80s F/mid 70s F
    surface temperatures/dewpoints becoming more widespread over land,
    ahead of an approaching confluence band. With time, convective cells
    both within and preceding this band should deepen and intensify as
    the boundary layer continues to destabilize.

    MLCAPE should only reach the 500-1000 J/kg range on a widespread
    basis, and be constrained to very thin vertical buoyancy profiles.
    Nonetheless, ample vertical wind shear remains prevalent with
    Isaias' remnants, with regional VADs still showing enlarged, curved
    low-level hodographs and over 400 m2/s2 of 0-3 km SRH. Therefore,
    isolated tornadoes will be possible with the stronger, persistently
    rotating updrafts that can develop within this marginally unstable
    but highly sheared airmass. The best chance for a tornado will be
    with any storms that interact with the northern extent of the more
    unstable airmass, which is serving as an effective warm front. If an appreciable uptick in updraft strength becomes evident, then a
    Tornado Watch issuance may be needed.
