    Areas affected...Parts of north central North Dakota

    Concerning...Severe Thunderstorm Watch 238...

    Valid 060752Z - 060845Z

    The severe weather threat for Severe Thunderstorm Watch 238

    SUMMARY...The risk for severe weather appears in the process of
    diminishing across much of southwestern through central North
    Dakota, and remaining valid portions of Severe Thunderstorm Watch
    238 will probably be allowed to expire as scheduled at 4 AM CDT.

    DISCUSSION...Strongest surface gusts continue with a 40-50+ kt rear
    inflow jet evident with a cluster of storms now spreading across and east-northeast of the Devils Lake area. Thunderstorm development
    trailing to the west-southwest, across central North Dakota persists
    in response to lift associated with lower/mid tropospheric warm
    advection. However, warmer and more strongly capping elevated
    mixed-layer air is forecast to advect back northeastward across much
    of north central North Dakota through 09-11Z, prior to the arrival
    the leading edge of the stronger mid-level cooling associated with
    the mid-level troughing crossing the northern Rockies. As this
    occurs, lingering convection is expected to continue to
    diminish/shift into Severe Thunderstorm Watch 239.
