    Mesoscale Discussion 0650

    1254 AM CDT Wed May 06 2026

    Areas affected...from southeast OK/northeast TX into parts of the
    Mid-South

    Concerning...Severe potential...Watch unlikely=20

    Valid 060554Z - 060800Z

    Probability of Watch Issuance...20 percent

    SUMMARY...An isolated severe threat may still develop overnight.

    DISCUSSION...Generally weak and disorganized convection is ongoing
    early this morning from parts of southeast OK into AR and western
    TN. Much of this activity is occurring just north of a
    southward-sagging cold front. Low-level warm/moist advection will
    continue to support elevated convection north of the boundary
    overnight, with MUCAPE of 1000-1500 J/kg and strong effective shear conditionally supporting organized convection. While storms have
    struggled thus far, it remains possible that an elevated supercell
    or more organized storm cluster could develop with time, posing a
    threat of isolated hail and strong/damaging gusts.=20

    Storms have also recently developed southwest of Little Rock, to the
    south of the primary front. While this convection may tend to remain
    elevated due to increasing low-level stability, there may be a
    window of opportunity for a near-surface-based storm to evolve
    near/south of the front before convection is undercut. Should this
    occur, a brief tornado threat could evolve, in addition to hail and damaging-wind potential.
