    Mesoscale Discussion 1850

    Areas affected...portions of southern and eastern Kansas into
    southwestern Missouri

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

    Valid 302216Z - 302345Z

    Probability of Watch Issuance...20 percent

    SUMMARY...A couple instances of large hail or severe gusts are
    possible with the stronger storms that manage to sustain themselves.
    However, the overall severe threat should remain isolated.

    DISCUSSION...Multiple multicellular clusters have developed along a
    diffuse baroclinic boundary, amid strong buoyancy but weak vertical
    wind shear. These storms are already demonstrating outflow
    tendencies, as noted on regional radar imagery and visible
    satellite. However, this outflow continues to propagate southward
    within a highly unstable airmass, characterized by over 3000 J/kg
    MLCAPE, driven primarily by upper 90s/low 70s F surface
    temperatures/dewpoints. Current thinking is that new updrafts will
    continue to develop on the leading edge of outflow, with a southward propagation expected. Given weak shear, primary convective mode
    should be outflow-dominant pulse cellular and multicellular storms.
    At the height of their intensity, storms may produce a couple
    instances of severe wind or hail. However, the severe threat should
    be isolated at best, and a Severe Thunderstorm Watch issuance is not
    currently anticipated.
