   As one mid/upper trough shifts eastward into the northern Plains and
   another trough approaches the British Columbia coast, a mid/upper
   ridge is expected to briefly build into portions of the Northwest on
   Thursday. In the wake of the leading trough, a cold front is
   expected to move through portions of the northern Rockies and
   northern High Plains, resulting in some increase in the fire weather

   ...Montana into the far western Dakotas...
   A relatively dry and breezy post-frontal regime will result in a
   threat of elevated fire weather conditions across much of Montana
   east of the Continental Divide. Sustained winds of 15-20 mph are
   possible as RH values drop to near or below 20% during the
   afternoon. While locally critical conditions are possible,
   confidence in sustained winds exceeding 20 mph is too low for an
   upgrade at this time. Elevated conditions may spread into adjacent
   portions of Wyoming and the western Dakotas, depending on the timing
   of the frontal passage during the afternoon. 

   Locally elevated conditions will be possible across portions of
   central/eastern WA/OR in the lee of the Cascades, and also across
   portions of the Snake River Valley in Idaho. RH may fall to near
   critical thresholds across these areas, though wind speeds are
   expected to remain relatively light outside of localized
   terrain-favored locations.
