    Areas affected...eastern South Dakota into western Minnesota

    Concerning...Severe potential...Watch unlikely

    Valid 080558Z - 080700Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Occasional strong to severe gusts will be possible through
    the morning across eastern SD into western MN.

    DISCUSSION...A line of thunderstorms is ongoing along arcing outflow
    across eastern SD. This will soon cross the surface boundary that
    extends across eastern SD into western MN. Recent gusts 60-63 mph
    were reported across eastern SD. The environment north and south of
    the boundary remains favorably sheared and unstable, with around
    1000-2000 J/kg of MLCAPE an 30-40 kts of deep layer shear.
    Inhibition is strong along and south of the boundary, likely meaning
    that storms are elevated in nature which may limit the overall
    severe potential. A few strong to severe gusts may be possible
    through the morning. A watch is unlikely to be needed but trends
    will be monitored.
