    Areas affected...Portions of northeastern CO into southern NE and
    far northern KS

    Concerning...Severe Thunderstorm Watch 410...411...

    Valid 290654Z - 290830Z

    The severe weather threat for Severe Thunderstorm Watch 410, 411
    continues.

    SUMMARY...Very large hail up to around 3 inches in diameter and
    severe/damaging winds will remain a threat as thunderstorms spread
    eastward early this morning.

    DISCUSSION...A parade of supercells producing large to very large
    hail up to 3.25 inches in diameter is ongoing across northeastern CO
    into far southwestern NE. The leading supercell in Hays/Hitchcock
    Counties in NE is the most intense, and this cell will likely remain
    capable of producing very large hail in the short term. The
    low-level jet feeding into these storms is rather strong, with 1 km
    AGL winds from VWPs at KDDC/KICT showing 50+ kt south-southwesterly
    flow. The airmass downstream of these supercells is also very
    unstable, with 3000+ J/kg of MUCAPE available to support continued
    robust updrafts. West-southwesterly winds strengthen with height at
    mid/upper levels, which is fostering 50-60+ kt of deep-layer shear.
    This very favorable thermodynamic and kinematic environment is
    expected to support a continued severe hail/wind threat over the
    next couple of hours as the supercells move eastward into
    south-central NE and perhaps far north-central KS. There is some
    potential for the leading supercell to grow upscale into a small bow
    with a corresponding increase in the threat for severe/damaging
    winds.
