    Concerning...Severe Thunderstorm Watch 472...

    Valid 090052Z - 090215Z

    The severe weather threat for Severe Thunderstorm Watch 472
    continues.

    SUMMARY...A severe-wind threat may spread eastward through the
    evening. Downstream WW issuance is possible.

    DISCUSSION...As of 0045 UTC, convection is relatively disorganized
    across northeast CO, though there has been some tendency for
    expanding outflow and a transition to more of a cluster or linear
    mode. As this convection spreads eastward, it will encounter richer
    low-level moisture and stronger instability (with MLCAPE increasing
    above 2000 J/kg), but there will also be a tendency for increasing
    CINH with the onset of nocturnal cooling. If a sufficiently robust
    cold pool can evolve this evening, then a storm cluster and possibly
    a small MCS may be able to overcome the near-surface stability and
    propagate eastward through the evening, with a threat for at least
    localized severe gusts (potentially near/above 75 mph due to
    favorable lapse rates and DCAPE). Moist, low-level easterly flow
    impinging upon the eastward-moving outflow renders this scenario
    plausible, and downstream watch issuance is possible as convection
    approaches the eastern extent of WW 472.
