    Mesoscale Discussion 1688
    NWS Storm Prediction Center Norman OK
    1115 AM CDT Tue Jul 21 2026

    Areas affected...northeast Kentucky...northern West Virginia...and
    southern Ohio

    Concerning...Severe potential...Watch likely

    Valid 211615Z - 211815Z

    Probability of Watch Issuance...80 percent

    SUMMARY...The severe weather threat will increase this afternoon
    across southern Ohio and northern Kentucky into West Virginia.

    DISCUSSION...A cluster of storms in southeast Ohio will likely
    continue east-southeast into a more unstable airmass along a
    differential heating zone developing across northern West Virginia.
    Damaging winds will likely be the primary threat with this cluster.
    Additional storms are expected to strengthen farther southwest
    through the afternoon with sufficient shear for some supercell
    structures. Damaging winds will likely be the main threat with this
    activity with some large hail potential. In addition, a tornado or
    two is also possible, especially as the low-level jet strengthens
    this afternoon/evening.

    A watch will likely be needed within the next 1 to 2 hours to
    address the threat from the ongoing activity and any additional
    storms which develop.
