    Mesoscale Discussion 1082

    Areas affected...Portions of southern Nebraska into southwest
    Iowa...northwest Missouri

    Concerning...Severe potential...Watch likely=20

    Valid 110651Z - 110845Z

    Probability of Watch Issuance...80 percent

    SUMMARY...A watch is likely for portions of southern Nebraska into southwestern/south-central Iowa. Large to very-large hail and
    isolated damaging winds are the main risks this morning.

    DISCUSSION...As a shortwave trough digs into the central Rockies, a
    surface low is deepening in western Kansas. Regional VAD data shows
    a 40-50 kt low-level jet advecting moisture into eastern Kansas and
    far southeastern Nebraska. Elevated storms have already formed in southwestern/south-central Nebraska. These storms have shown some
    potential for large hail on MRMS MESH. With the influx of moisture
    above the surface, the expectation is for this activity or
    additional storms along the quasi-stationary boundary to intensify
    this morning. Large to very-large hail will likely be the primary
    threat given the elevated nature of convection. That being said, the boundary-layer will not be prohibitively stable. At least some risk
    for damaging winds will exist as well. The strong warm advection
    wind profile will also mean enlarged low-level hodographs. While
    rather conditional, a tornado would be possible with supercell
    structures and at least low 70s F dewpoints.
