    Areas affected...Parts of eastern South Dakota and southwestern
    Minnesota

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

    Valid 220124Z - 220300Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Locally damaging wind gusts are possible with a
    southward-moving cluster of storms.

    DISCUSSION...Earlier semi-discrete thunderstorms have evolved
    upscale into a small cluster of storms, with an embedded supercell
    still evident. These storms are tracking southward along the eastern
    periphery of moderate-strong surface-based buoyancy (per modified
    00Z ABR sounding). The consolidated/organized cold pool and robust
    updrafts (including the embedded supercell) will continue to pose a
    risk of locally damaging wind gusts with southward extent. However,
    gradually increasing nocturnal stability in the boundary layer and
    gust-front parallel deep-layer flow/shear should tend to limit the
    potential for forward propagation and the overall coverage of
    severe-wind.
