  Western and central North Dakota

  until 200 AM CDT.

SUMMARY...Lines of storms, with a history of severe winds in excess
of 80 mph, will spread quickly eastward from eastern Montana into
North Dakota through early tonight.  The storm environment will
likely maintain the damaging-wind threat with bowing segments, as

isolated tornado or two will also be possible with embedded
circulations.

The severe thunderstorm watch area is approximately along and 105
statute miles east and west of a line from 55 miles north northwest
of Minot ND to 20 miles east of Lemmon SD. For a complete depiction
of the watch see the associated watch outline update (WOUS64 KWNS
