    Areas affected...northeast Colorado...western Nebraska...and far
    northwest Kansas

    Concerning...Severe Thunderstorm Watch 262...

    Valid 020023Z - 020200Z

    The severe weather threat for Severe Thunderstorm Watch 262
    continues.

    SUMMARY...Severe thunderstorms will continue moving east across the
    area this evening. A new watch will likely be needed east of Severe Thunderstorm Watch #262.

    DISCUSSION...Multiple clusters of severe thunderstorms continue
    across Severe Thunderstorm Watch #262 this evening. One such cluster
    is moving east across the Nebraska panhandle. This cluster has a
    history of producing hail around 1" and a brief tornado. To the
    south, another cluster of storms is moving east across northeast
    Colorado into northwest Kansas. This cluster also has a history of
    producing severe reports, with a 1" hail report noted near Yuma, CO.
    These storms are ongoing within a favorable environment for severe
    storms, with MUCAPE around 500-1000 J/kg (increasing to greater than
    1500 J/kg ahead of the storms) and effective-layer shear on the
    order of 40-50 knots.=20

    These storms should continue moving east and may eventually grow
    upscale and merge into a linear system as it moves east out of the
    Severe Thunderstorm Watch. As such, a new watch will likely be
    needed east of Watch #262.
