  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
