    Mesoscale Discussion 0960
    NWS Storm Prediction Center Norman OK
    0440 PM CDT Sat Jun 30 2018

    Areas affected...Portions of the Missouri Valley

    Concerning...Severe potential...Watch possible

    Valid 302140Z - 302315Z

    Probability of Watch Issuance...60 percent

    SUMMARY...Developing storms will pose a risk of damaging winds and
    large hail. A watch may be needed if convective trends warrant.

    DISCUSSION...A very evident MCV is lifting north/northeast towards
    the Kansas/Nebraska border this afternoon. Focused ascent ahead of
    and on the eastern flank of this circulation is assisting new
    convective development from the MCV to the KC Metro late this
    afternoon. Regional VWP data are not sampling much directional
    shear, but strong buoyancy combined with enhanced southwesterly flow
    aloft (around 35-45 kt at 6 km) will likely support damaging
    downburst winds and isolated large hail with cluster/multicellular
    modes. Convective coverage/organization may warrant new watch
    issuance.
