    Areas affected...north-central and northeast North Dakota

    Concerning...Severe potential...Watch unlikely=20

    Valid 112342Z - 120115Z

    Probability of Watch Issuance...5 percent

    SUMMARY...The potential for locally strong wind gusts will exist
    with any deeper convective elements through about 01z. A watch is
    not anticipated.

    DISCUSSION...A small thunderstorm has recently developed over
    McHenry into Pierce Counties along a surface trough, where a narrow
    axis of locally higher moisture content exists. The moisture
    combined with a plume of very steep, low/mid-level lapse rates is
    resulting in estimated MUCAPE of 250-500 J/kg. Forecast soundings
    suggest that the ambient environment features a deeply mixed
    boundary layer extending upwards of 3 km, where westerly winds of
    30-40 kt exist. As such, there appears to be some potential for
    locally strong wind gusts for the next couple or hours with any
    deeper convective elements before the boundary layer begins to cool
    and stabilize.
