    Areas affected...Parts of southern/central AR into northwest MS

    Concerning...Severe Thunderstorm Watch 28...

    Valid 091703Z - 091830Z

    The severe weather threat for Severe Thunderstorm Watch 28
    continues.

    SUMMARY...The risk of severe hail and locally damaging gusts
    continues across Severe Thunderstorm Watch #28, and will gradually
    spread eastward into MS -- where a new watch may eventually be
    needed.

    DISCUSSION...A cluster of thunderstorms continues tracking eastward
    across central AR, with deeper/embedded cores noted along the
    southern fringes of this activity. As low-level moisture continues
    streaming northward amid filtered diurnal heating, the stronger
    cores capable of producing severe hail and locally damaging gusts
    may remain focused over the southern periphery of the larger
    cluster. With time, these storms will continue spreading eastward
    into northern/central MS, with additional warm-advection-driven
    development also possible. Increasing buoyancy into this corridor
    and around 40 kt of effective shear will promote a continued risk of
    large hail and damaging gusts. While timing is uncertain, a
    downstream watch may eventually be needed.
