    Mesoscale Discussion 1816

    Areas affected...far eastern Kansas into much of central Missouri

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

    Valid 022230Z - 030130Z

    Probability of Watch Issuance...80 percent

    SUMMARY...Storms are likely to develop this evening from far eastern
    Kansas across much of central Missouri. Damaging winds will be the
    primary risk, but hail may occur as well.

    DISCUSSION...Surface analysis shows a plume of hot air with much of
    northern OK into southeast KS over 105 F. Stronger boundary-layer
    mixing is occurring beneath the stronger southwesterly flow aloft
    with surface gusts of 20-25 kt within the heating zone. Despite
    this, dewpoints remain in the 60s F, with 70s farther east of the
    hot axis into MO.

    A stationary front will be the main focus for develop over the next
    few hours, and this extends from south of Emporia KS across the Lake
    of the Ozarks and into southeast MO. Here, mid to upper 70s F
    dewpoints remain, with MLCAPE over 3000 J/kg and precipitable water
    to around 2.00".=20

    An uncapped air mass along with speed convergence over southeast KS
    into western MO near the boundary will support storm initiation
    close to 00Z. Visible imagery already shows towering cumulus over
    southeast KS, which appears to be the initiation zone. Depending on
    the slope of the cooler air north of the front, additional activity
    could form farther away from the boundary. If this occurs, hail
    would be more likely as deep-layer shear increases substantially
    with northward extent. Initial storm development near the boundary
    will likely move slowly northeastward, with possible upscale growth
    and potential acceleration by late evening as a cold pool grows.
