    Mesoscale Discussion 0898

    Areas affected...Central/Eastern Kansas and Western Missouri

    Concerning...Severe potential...Watch unlikely

    Valid 270030Z - 270230Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Storms have formed along an east/west surface boundary
    stretching across central/eastern Kansas into western Missouri.
    Hail/strong wind gusts are the main threats, but brief tornadoes are
    possible.

    DISCUSSION...The atmosphere has destabilized across portions of
    Kansas/Missouri during the last few hours in the wake of a MCS.
    Moderate-strong buoyancy (MLCAPE 1500-3000 J/kg) and shear
    (effective bulk shear of 35-55 knots) indicate a conducive
    environment for strong/severe storm development. Farther to the
    west, the storms are most likely surface-based and interacting with
    a remnant outflow boundary, which is where brief tornadoes are
    possible across Butler/Elk/Greenwood counties. Severe hail/wind are
    also possible with these storms as they slowly build/track to the south/southeast. Storms should diminish after sunset. However, there
    is a possibility of upscale organization that would let storms
    continue through the evening. If this occurs, a watch may be needed.
