    Areas affected...portions of the eastern Dakotas and western
    Minnesota

    Concerning...Tornado and Severe Thunderstorm Watches 297...298...

    Valid 100419Z - 100615Z

    The severe weather threat for Tornado and Severe Thunderstorm
    Watches 297, 298 continues.

    SUMMARY...Damaging wind potential continues within WW297 and 298.

    DISCUSSION...A squall line continues eastward across the eastern
    Dakotas into Minnesota, with 60-75 mph gusts observed in the last
    hour. Two areas of this line have shown an increase in damaging wind
    potential over the last hour.

    The line in northeastern South Dakota outside of Aberdeen has
    recently produced gusts to 75-77 mph, with a bowing segment becoming
    apparent. This area will be a focus of severe to significant severe
    wind potential (70-80 mph) given the favorably strong instability
    downstream.

    Further north across northern North Dakota, the northern segment of
    the squall line has become more progressive. The VAD profile from
    MVX shows an increase in the low-level jet, with 50-60 kt southerly
    flow in the lowest 1-2 km. This area may also develop as a more
    favorable corridor for severe wind potential in the short term given
    the increase in the LLJ and favorably warm and unstable environment
    downstream.
