    Areas affected...far southeast SD...eastern NE into western/central
    IA

    Concerning...Severe Thunderstorm Watch 475...

    Valid 120941Z - 121115Z

    The severe weather threat for Severe Thunderstorm Watch 475
    continues.

    SUMMARY...Severe thunderstorm gusts will continue across WW 475.

    DISCUSSION...A well organized bowing MCS will continue to track
    southeast into eastern NE/western IA this next few hours. A swath of
    intense gusts to 75 mph will be possible near the apex of a bowing
    segment from near Pierce and Madison Counties toward the Omaha
    vicinity through 12z. With time, gradual weakening of the bow is
    expected with south/east extent as the low-level jet weakens after
    12z. However, given the well developed nature of convection and
    strong deep-layer northwesterly flow amid strong instability, severe
    potential could persist at least briefly beyond the eastern/southern
    bounds of WW 475. A downstream watch across parts of central IA
    likely will be needed.
