Areas affected...north-central ND

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.
