    Mesoscale Discussion 1560
    NWS Storm Prediction Center Norman OK
    0353 PM CDT Thu Jul 09 2026

    Areas affected...Southeast Kansas into south-central Missouri and
    northern Arkansas

    Concerning...Severe potential...Watch possible

    Valid 092053Z - 092300Z

    Probability of Watch Issuance...60 percent

    SUMMARY...A watch is possible late this afternoon as storms form
    along an outflow/differential heating boundary. Shear is sufficient
    for marginal supercells capable of all hazards.

    DISCUSSION...Airmass recovery continues in the wake of an MCV that
    moved through Missouri earlier today. Temperatures to the southwest
    of the outflow/differential heating boundary have risen in the upper
    80s to low 90s F. Warm advection within this zone as well as near a
    weak surface low in southeast Kansas will eventually initiate a few thunderstorms. CAM guidance has generally suggested this will occur
    by 5 PM CDT or thereabouts. Enhanced shear from the MCV (30-35 kt
    effective shear) will promote marginal supercell structures. The
    primary hazards will be isolated large hail and damaging winds.
    Low-level flow is strong enough (see the KSGF VAD) to support
    rotating storms. Should supercells maintain intensity, a risk for a
    tornado could develop near the surface boundary.
