...Synopsis...
Broad upper-level cyclonic flow will shift eastward into the
northern Plains/upper-Midwest during the D2/Monday period. At the
surface, high pressure will build into parts of the Pacific
Northwest and northern Rockies with a thermally-induced pressure
trough present across northern California. With mid-level winds
waning across areas of dry fuels, as well as a generally weak
surface pressure gradient across the northwestern quarter of the
CONUS, fire weather concerns will be reduced below elevated levels
in most locations. Locally elevated conditions will be most likely
in portions of southern Wyoming and perhaps the Snake River Valley
where some residual mid-level flow will exist. However, conditions
are expected to be relatively brief and occur over areas with a
general lack of fuels.

With higher pressure over Montana and a pressure trough along the
Oregon coast, portions of the Willamette Valley will see easterly
downslope flow during the evening/overnight. RH values may dip to
30-35%. Based on available guidance, winds do not appear likely
reach the sustained 15 mph threshold except on a localized basis.
