    The severe weather threat for Severe Thunderstorm Watch 514

    SUMMARY...Damaging wind threat will spread into southwestern
    Minnesota over the next few hours. New severe thunderstorm watch
    will likely be warranted by 10/00z.

    DISCUSSION...Squall line has matured and is advancing east-northeast
    at roughly 30-35kt across the northeastern half of ww514. Latest
    diagnostic data suggests surface low is located over southeast SD,
    very near the southern updraft along the squall line over Kingsbury
    County. Focused LLJ is shifting downstream across southwestern MN
    and this will encourage a well-organized MCS to propagate east of
    the current watch in the next 1-2 hours. Damaging winds have been
    reported along the leading edge of the squall line, and should
    continue for the next several hours as significant buoyancy resides
    ahead of this activity across southern/central MN. While damaging
    winds are the primary severe risk, especially given the linear storm
    mode, wind profiles and radar data suggest one or two brief
    tornadoes along the QLCS as it propagates east-northeast.
