    Areas affected...Central and Eastern South Dakota...Southwest
    Minnesota

    Concerning...Severe Thunderstorm Watch 527...529...

    Valid 140629Z - 140830Z

    The severe weather threat for Severe Thunderstorm Watch 527, 529
    continues.

    SUMMARY...A wind-damage and large-hail threat will likely continue
    across parts of central and eastern South Dakota over the next few
    hours, and could affect southwest Minnesota later tonight. Gusts
    over 80 mph will be possible ahead of the ongoing bow. Weather watch
    issuance will need to be considered for parts of eastern South
    Dakota.

    DISCUSSION...The latest mosaic radar imagery shows a well-developed
    bow echo just to the west and northwest of Pierre, South Dakota. The
    bow is moving east-southeastward along a corridor of moderate
    instability, where the RAP is analyzing MLCAPE in the 1200 to 2000
    J/kg range. The line appears to be supported by a 45 to 55 knot
    mid-level speed max over northwestern South Dakota. As the line
    continues to move east-southeastward at around 50 knots, severe
    gusts will be likely along the leading edge of the bow. Wind gusts
    above 80 mph will be possible near the apex of the bow. As the line
    moves further east, it will encounter stronger instability across
    southeastern South Dakota. This could help to maintain intensity
    with the line, making weather watch issuance likely across parts of
    eastern South Dakota and southwest Minnesota.
