    Areas affected...eastern Wyoming into western Nebraska and portions
    of eastern Colorado

    Concerning...Severe Thunderstorm Watch 358...

    Valid 222356Z - 230130Z

    The severe weather threat for Severe Thunderstorm Watch 358
    continues.

    SUMMARY...Ongoing strong to severe storms will remain capable of
    hail and damaging gusts into this evening.

    DISCUSSION...Broad upslope across the Front Range has resulted in
    scattered strong to severe storms from eastern WY to western NE and northeastern CO early this evening. Storm coverage has gradually
    increased over the last couple of hours with numerous storm
    interactions resulting in some upscale growth. Despite cooling from
    anvil shading and consolidating storm outflow, remnant buoyancy,
    (1000-1500 J/kg of MCLAPE) and 40 kt of effective hear will continue
    to support storm organization this evening. Two stronger clusters
    are now evident, one just southeast of Denver, and the other near
    the WY/NE border. The primary severe risk is likely to remain
    concentrated with these clusters through the next couple of hours.
    Given the favorable buoyancy and shear, large hail will remain
    possible with some supercell structures. Upscale growth of the
    clusters may also support damaging gusts with the strongest storms.
    The severe risk should continue into this evening before nocturnal stabilization results in gradual downtrend in convective intensity
    into the overnight.
