    Areas affected...south-central into northeast KS...northwest into
    north-central MO

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

    Valid 242342Z - 250145Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Strong to locally severe storms will be possible this
    evening, with a threat of isolated hail and strong to severe wind
    gusts.

    DISCUSSION...Storm coverage is increasing early this evening from
    central KS into northwest MO. Storms to the north/northeast of
    Kansas City have developed just to northeast of a warm front and are
    likely somewhat elevated. Persistent low-level warm/moist advection
    will help to sustain these storms as they approach north-central MO.
    Moderate elevated buoyancy (with MUCAPE of 1000-1500 J/kg) and
    sufficient deep-layer shear could support marginal supercell
    structures with a threat for isolated large hail. Also, despite this
    convection being somewhat elevated, a dry near-surface layer beneath
    the elevated moist plume could support some stronger wind gusts this
    evening as storms spread northeastward.=20

    Farther west, scattered storm development is ongoing from
    south-central into northeast KS, as a southeastward-moving cold
    front begins to intercept a pre-frontal surface trough and
    relatively greater instability. While low-level moisture remains
    rather limited, strong diurnal heating has resulted in MLCAPE
    increasing into the 500-1000 J/kg range, along with weakening
    MLCINH. Increasing deep-layer flow/shear associated with an
    approaching midlevel shortwave trough will support some organized
    convection through the evening.=20

    Rather strong low-level flow (30-40 kt in the 1-3 km layer per
    regional VWPs) and steep low-level lapse rates will support
    potential for strong to locally severe gusts within this regime,
    especially if any organized clustering occurs. Isolated hail will
    also be possible, especially into east-central/northeast KS and
    northwest MO, where somewhat more favorable moisture and buoyancy
    will be in place.
