    Mesoscale Discussion 1822
    NWS Storm Prediction Center Norman OK
    1209 PM CDT Sun Aug 02 2026

    Areas affected...portions of the Central Appalachians

    Concerning...Severe potential...Watch unlikely

    Valid 021709Z - 021915Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Sporadic strong wind gusts are possible through the
    afternoon. Overall severe potential is expected to remain limited
    and a watch is not currently anticipated.

    DISCUSSION...Thunderstorms are gradually increasing in coverage and
    intensity early this afternoon across the higher terrain of West
    Virginia. Additional convection is expected to develop with
    southward extent as modest destabilization continues into the
    afternoon. Rich boundary layer moisture with dewpoints in the upper
    60s to mid 70s is fostering up to 1000 J/kg MLCAPE, though lapse
    rates are expected to remain modest today. Stronger vertical shear
    in proximity to the upper trough and surface low, with effective
    shear magnitudes in the 25-35 kt range, will support occasional
    organized clusters capable of producing locally strong wind gusts.
    Backed low-level flow, with vertically veering wind profiles, will
    support modest 0-1 km SRH (around 100 m2/s2 per latest SPC
    Mesoanalysis). This could support modest storm rotation, and a brief
    tornado also is possible, though this risk will be muted by poor
    low-level lapse rates and overall weak thermodynamic profiles. The
    overall severe risk is expected to remain limited/transient across
    the broader region, and a watch is not currently expected.
