    Mesoscale Discussion 0885
    NWS Storm Prediction Center Norman OK
    0517 PM CDT Mon May 19 2025

    Areas affected...Parts of far east-central Colorado into western
    Kansas

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

    Valid 192217Z - 200015Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Isolated instances of large hail and locally severe gusts
    will remain possible for the next few hours. Given the
    localized/isolated nature of the severe risk, a watch is not
    currently expected.

    DISCUSSION...Beneath the large-scale trough now centered over the
    central Rockies/High Plains, cold midlevel temperatures atop a
    deeply mixed boundary layer are contributing to steep deep-layer
    lapse rates across east-central CO into western KS -- with around
    800 J/kg MLCAPE. With around 30 kt of effective shear, marginal
    supercell structures will be capable of producing isolated large
    hail and locally severe gusts (one earlier report of 2.5 inch hail).
    However, given the somewhat marginal deep-layer shear and buoyancy,
    the overall severe risk is expected to remain too sporadic/isolated
    for a watch at this time.
