    Mesoscale Discussion 1747

    Areas affected...North-Central/Northeast KS

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

    Valid 212155Z - 220000Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Isolated hail and damaging gusts are possible this
    afternoon and evening across north-central/northeast Kansas. Limited
    severe coverage should preclude the need for a watch.

    DISCUSSION...Strong/severe thunderstorms have developed over
    north-central KS amid a localized area of strong buoyancy and
    low-level convergence. Deep-layer vertical shear is weak and overall
    storm motion has been very slow. Deepening cumulus is also apparent
    along the outflow southwestward of this storm. Ample buoyancy exists
    across the region, suggesting additional storm development is
    possible. However, given the limited shear and anticipated lack of
    storm organization, the overall longevity of any particular updraft
    should be limited. Even so, isolated hail is possible with the
    initial updrafts. Strong downbursts are possible as storms collapse.
    =20

    Farther east, outflow from earlier storms continues to push
    southwestward across northeast KS, with temperatures in the upper
    70s and low 80s behind it. This should limit the intensity of storms
    across northeast KS. However, the cluster across Washington and
    Marshall has shown some trend towards forward propagation recently,
    suggesting some damaging gust are possible even as it moves into the stabilizing airmass downstream.
