    Areas affected...West-central into northern Minnesota

    Concerning...Severe Thunderstorm Watch 298...

    Valid 100642Z - 100845Z

    The severe weather threat for Severe Thunderstorm Watch 298
    continues.

    SUMMARY...The threat for severe gusts/wind damage will increase into
    portions of northern Minnesota tonight. Isolated large hail and a
    QLCS tornado threat will also exist. A new watch is possible for north-central/northeast Minnesota within the next 1-2 hours.

    DISCUSSION...A small bowing segment is moving into west-central
    Minnesota. This portion of the broader convective line has been
    responsible for multiple severe gusts in northeastern South Dakota
    and southeastern North Dakota tonight. Given the favorable
    orientation of the line with respect to the deep-layer shear vector,
    this activity will likely be the focus for severe gusts/wind damage
    over the next few hours. While dewpoints do decrease farther
    northeast, some modest theta-e advection is expected to occur
    immediately ahead of this bowing structure. Steep mid-level lapse
    rates are still in place across the region so isolated large hail is
    possible even with a linear storm mode. A QLCS tornado also is
    possible. A new watch is possible for portions of
    north-central/northeast Minnesota within the next couple of hours.
