    Areas affected...Eastern Colorado

    Concerning...Severe Thunderstorm Watch 639...

    Valid 200007Z - 200100Z

    The severe weather threat for Severe Thunderstorm Watch 639
    continues.

    SUMMARY...Storms capable of damaging winds and hail are ongoing
    across the WW 639, and are expected to persist into the early
    evening hours.

    DISCUSSION...A few ongoing convective clusters will continue to be
    capable of damaging winds and hail, supported by MLCAPE > 2000 J/kg
    and 45-50 kts of deep-layer vertical shear. Recent radar over
    east-central and southeastern Colorado shows outflow surging ahead
    of the convection, and the greatest threat for any damaging winds
    will be with any upscale growth that occurs on the leading edge of
    this outflow. In northern Colorado, a more isolated supercell
    thunderstorm is ongoing, with southeasterly flow and temperatures in
    the mid-to-upper 70s F out ahead of it. This should support at least
    some maintenance of a severe threat into the evening hours.
    Convective coverage and intensity should diminish as the nocturnal
    boundary layer stabilizes, with watch expiration set for 03Z.
