    Concerning...Severe Thunderstorm Watch 547...

    Valid 270921Z - 271015Z

    The severe weather threat for Severe Thunderstorm Watch 547
    continues.

    SUMMARY...Severe wind threat should diminish in coverage and
    intensity as it shifts northeastward across north-central North
    Dakota over the next 2-3 hours.

    DISCUSSION...A consolidated but shrinking QLCS is progressing east-northeastward from western into north-central ND. The more
    productive portion with measured severe gusts has been across the
    southern flank, where greater MLCAPE had been present. But the
    southern flank is eroding due to a combination of warming/drying
    700-mb temperatures and impingement on prior overturned air. NDAWN
    surface observations confirm about a one county-wide corridor of mid
    to upper 60s surface dew points exists ahead of the line into
    north-central ND. As this overturns, severe wind magnitudes should
    diminish after daybreak.
