    Areas affected...Eastern/East-Central CO...Far Western KS

    Concerning...Severe potential...Watch likely=20

    Valid 161836Z - 162030Z

    Probability of Watch Issuance...80 percent

    SUMMARY...Thunderstorms are expected to increase in coverage and
    intensity from central into eastern CO this afternoon. Hail is
    possible with these storms early, with damaging gusts more likely
    later this afternoon and evening. The threat for damaging gust will
    likely continue in western KS.

    DISCUSSION...The air mass across eastern CO continues to destabilize
    amid strong daytime heating ahead of a shortwave trough moving
    through the Four Corner vicinity. A corridor of slightly higher
    dewpoints exists along a weak front that parallels the Palmer Divide
    in CO and then arcs back northeast through northwest KS.
    Mesoanalysis estimates that minimal convective inhibition exists
    along and north of this corridor, while some inhibition still
    remains within the more mixed boundary layer farther south.=20

    Expectation is for thunderstorm coverage to gradually increase over
    the higher terrain before then moving eastward into the lower
    elevations. Instability will remain modest, with around 1000 J/kg of
    MLCAPE anticipated across much of eastern CO this afternoon.
    Southwesterly mid-level flow will strengthen slightly ahead of the
    approaching shortwave, which, when combined with the more easterly
    surface winds, will result in vertically veering wind profile. The
    initial development may be more discrete, with hail as the primary
    risk. Thereafter, one or more bowing segments may develop, with wind
    gusts becoming the primary risk. The west-to-east orientated surface
    boundary may act as a favored corridor for upscale growth and
    forward propagation.
