    Areas affected...portions of extreme northeast Colorado into western
    Nebraska and far south-central South Dakota

    Concerning...Severe Thunderstorm Watch 544...

    Valid 270016Z - 270145Z

    The severe weather threat for Severe Thunderstorm Watch 544
    continues.

    SUMMARY...Severe gusts will remain a concern over the next several
    hours with an eastward-advancing MCS.

    DISCUSSION...An MCS is organizing over western NE, where several
    sub-severe gusts have been measured. Over the next several hours,
    this MCS cold-pool-driven MCS will propagate eastward amid 3000+
    J/kg MLCAPE. Deep-layer shear is not overly strong, and MLCINH is
    beginning to increase across the central Plains. Nonetheless, the
    25+ kt effective bulk shear vectors in place are roughly normal to
    the MCS leading line, so continued organization is not out of the
    question. Should the MCS continue to intensify, severe gusts may
    become more probable before the MCS becomes increasingly elevated
    with strengthening MLCINH.
