    Areas affected...portions of central SD and NE

    Concerning...Severe Thunderstorm Watch 403...406...

    Valid 280238Z - 280415Z

    The severe weather threat for Severe Thunderstorm Watch 403, 406
    continues.

    SUMMARY...Ongoing strong to severe storms near the NE/SD border will
    likely continue to pose a risk for damaging gusts and hail for a bit
    longer this evening. Greater uncertainty exists with storms into
    central NE.

    DISCUSSION...As of 0235 UTC, a linear cluster of strong to severe
    storms near the NE/SD border remains fairly strong and well
    organized this evening. Recent observational and hi-res model trends
    suggest these storms will likely continue to pose a risk for
    damaging gusts and some hail for a couple more hours tonight. A
    local extension of some counties along the NE/SD border may be
    necessary as storms approach the edges of WW406 and 403.

    Farther south, convection has struggled to maintain intensity away
    from better forcing for ascent and cooler mid-level temperatures.
    While an isolated severe risk remains possible into central NE
    tonight, confidence in a sustained severe risk is low. As storms
    track farther east they will gradually encounter increasing
    inhibition and weaker buoyancy into the overnight hours. Weakening
    appears likely, though isolated damaging gusts may persist beyond
    the eastern edge of the watches tonight.
