    Mesoscale Discussion 1819
    NWS Storm Prediction Center Norman OK
    0644 PM CDT Sat Aug 01 2026

    Areas affected...Parts of eastern IN/KY...western
    OH...middle/eastern TN

    Concerning...Severe potential...Watch unlikely

    Valid 012344Z - 020145Z

    Probability of Watch Issuance...20 percent

    SUMMARY...A threat for a brief tornado or two and/or locally
    damaging wind may continue through dusk.

    DISCUSSION...An arc of thunderstorms is ongoing this evening from
    eastern IN into southwest OH, eastern KY, and middle TN, in
    association with a broad deep-layer clone over IL/IN and surface
    trough that trails into the OH/TN Valleys. Multiple cells within
    convective arc have developed brief/transient rotation over the last
    1-2 hours, aided by low-level vorticity near the surface cyclone and
    some SRH enhancement noted on the KILN VWP. Rich low-level moisture
    is supporting MLCAPE of 1000-2000 J/kg, though poor lapse rates may
    continue to temper updraft intensity and the longevity of the severe
    threat with any particular storm. The strongest cells through dusk
    will remain capable of producing a brief tornado or two and/or
    locally damaging winds.
