    Areas affected...portions of far southeast Colorado into far
    southwestern Kansas

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

    Valid 162147Z - 162315Z

    Probability of Watch Issuance...20 percent

    SUMMARY...A few instances of severe hail may accompany the stronger
    storms that can mature, and a severe gust also cannot be ruled out.

    DISCUSSION...Thunderstorms have been increasing in intensity across southeastern CO into southwestern KS over the past 1-2 hours, with
    50+ dBZ cores occasionally exceeding 30 kft per MRMS mosaic radar
    imagery. These storms are developing amid a steep mid-level lapse
    rate environment (e.g. 8 C/km), yielding 1500-2500 J/kg MLCAPE.
    Despite favorable buoyancy, vertical wind shear is relatively poor,
    and forcing for ascent should remain weak as well, which should
    limit the overall severe threat. Nonetheless, given steep mid-level
    lapse rates, any storm that can mature and achieve at least
    transient supercell structure may produce isolated instances of
    severe hail and perhaps a severe gust or two.
