    Areas affected...southeast South Dakota...southwest Minnesota...and
    northwest Iowa.

    Concerning...Severe Thunderstorm Watch 654...

    Valid 270541Z - 270715Z

    The severe weather threat for Severe Thunderstorm Watch 654
    continues.

    SUMMARY...The threat for severe storms will continue early this
    morning across southeast South Dakota, southwest Minnesota, and
    northwest Iowa.

    DISCUSSION...A few storms along the remnant outflow boundary from
    the earlier MCS have strengthened across eastern South Dakota in the
    last hour. This is a trend which may continue over the next 1 to 2
    hours as this boundary and ongoing storms advance toward an
    increasingly unstable airmass. Given the strengthening which has
    already occurred amid ~1000 J/kg MLCAPE and mid to upper 60s
    dewpoints, expect additional strengthening as storms move into low
    70s dewpoints and only weak inhibition north of the surface low
    across southeast South Dakota, northwest Iowa, and potentially
    southwest Minnesota. Severe gusts will be the primary threat, but
    at least some large-hail threat will persist as any storms remain
    more discrete/supercellular.=20

    Eventually, storms will move ahead of the better shear (near the
    eastern bounds of watch 654) which will likely bring an end to the
    more organized severe weather threat. However, in the interim, a
    favorable environment remains for a few potentially potent severe
    storms.
