    Areas affected...parts of eastern Wyoming and northern Colorado

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

    Valid 241941Z - 242145Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Storms may produce a few instance of large hail and a few
    severe gusts across portions of eastern Wyoming and northern
    Colorado. A watch is not anticipated.

    DISCUSSION...Convection has developed along the mountains across
    parts of eastern Wyoming and northern Colorado, where diurnal
    inhibition has eroded. Farther east across the High Plains, some
    inhibition remains for mixed-layer parcels, but additional heating
    should continue to erode the MLCINH as the afternoon progresses.
    Kinematically, the region is on the southern periphery of a modest
    mid-level jet. This should provide sufficient shear for at least
    transient supercells, and in some places low-level wind profiles
    favor left-moving supercells. Given the long hodographs and steep
    lapse rates with low freezing levels, some hail is possible with the
    strongest storms. Shear decreases with southward extent, so this may
    put a limit on the southern extent of the hail risk. With time,
    storms may begin to cluster, and these clusters may also produce a
    risk for severe gusts given the relatively dry boundary layer and
    steep low-level lapse rates. Given the expected sparse coverage of
    severe weather, a watch is not anticipated.
