Day 2 Fire Weather Outlook

Valid 281200Z - 291200Z

...Synopsis...
Low-amplitude mid-level troughing over the Northern Rockies will
begin to shift eastward Saturday as high pressure over the southern
US continues to build. A belt of stronger mid-level flow will remain
in place over parts of the Intermountain West, supporting dry
downslope flow ahead of a weak cold front over the Northwest.

...ID into southwest WY...
Gusty surface winds through central ID and southwest WY could
support a few hours of elevated fire-weather potential Saturday. In
the wake of the departing upper trough, continued mid-level zonal
flow will linger over central ID. Confidence is highest that 15-20
mph surface winds will occur across portions of the central and
eastern Snake River Plain Saturday afternoon. Coincident with RH
below 20%, elevated fire-weather conditions are probable amid fuels
that continue to dry.

Farther east into WY, less confidence exists in sustained surface
winds greater than 15 mph occurring on a widespread basis through
the day. However, a very warm and dry air mass will remain in place.
This could support some localized fire-weather concerns, especially
where terrain-augmented winds may occasionally gust to 15-20 mph.
