    Areas affected...much of central Nebraska

    Concerning...Severe Thunderstorm Watch 533...

    Valid 302241Z - 302345Z

    The severe weather threat for Severe Thunderstorm Watch 533
    continues.

    SUMMARY...A growing and organizing cluster of storms accompanied by
    increasing potential to produce swaths of strong to severe wind
    gusts appears probable through 7-9 PM CDT. Trends are being
    monitored for the possibility of an additional severe weather watch
    east and south of Severe Thunderstorm Watch 533.

    DISCUSSION...Vigorous convective development continues to gradually
    grow upscale, with an expanding and strengthening surface cold
    pool, which will continue to slowly advance south of the Winner SD,
    Valentine and Ainsworth NE vicinities during the next few hours.
    The most intense cell has generally been focused along the
    southwestern flank of the outflow, where low-level convergence has
    become enhanced near its intersection with a weak wind shift within
    broader weak surface troughing. However, south-southeasterly
    updraft inflow of seasonably high low-level moisture content (which
    appears to be contributing to CAPE in excess of 3000 J/kg) may
    support a broader area of intensifying convection into the 00-02Z
    time frame.

    Although deep-layer westerly mean flow is still modest (on the order
    of 20 kt), due to pronounced veering of low through mid-level wind
    fields, shear through the lowest 5-6 km is strong and may support
    the evolution of an organizing cluster with increasing potential to
    produce swaths of strong to severe wind gusts.
