   ...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.

   Day 3-8 Fire Weather Outlook

   0451 PM CDT Thu Jun 26 2025

   Valid 281200Z - 041200Z

   ...Day 3-4/Saturday-Sunday...
   Stronger westerly mid-level winds under a largely zonal flow pattern
   will remain across the Pacific Northwest and Northern Tier states
   through the weekend. This will support breezy valley winds within
   the Snake River Plain on Day 3/Saturday. These winds will overlap
   within a dry boundary layer/low relative humidity environment where
   fuels continue to dry, becoming more receptive to wildfire spread.

   ...Day 5-7/Monday-Wednesday...
   Increasing mid-level lapse rates, moisture and elevated instability
   along with supportive dynamics from incoming upper-level trough will
   promote shower and thunderstorm development across northern
   California and along and just east of the Oregon Cascades beginning
   as early as Day 4/Sunday, heading into the Day 5/Monday time frame.
   The initial build up of mid-level moisture and convection over a
   dry, sub-cloud layer will inhibit higher rain amounts under nascent
   thunderstorms. Fuels will undergo further drying through the weekend
   with above normal temperatures and dry conditions. ERC values near
   the 90th percentile are expected by early next week, increasing
   ignition potential. Increasing atmospheric moisture Day 6/Tuesday
   should promote higher rainfall amounts, limiting dry thunderstorm
   threat across the Cascades and portions of central Oregon. A drier,
   downslope flow pattern returns to the Cascades Day 7/Wednesday as
   the leading mid-level trough axis shifts east into the Great Basin
   and Northern Rockies. This would allow potential holdover ignitions
   to be exposed to an environment more favorable to fire spread.

   ...Day 8/Thursday...
   Long term ensemble guidance indicates a weak mid-level trough
   lingering across the Western U.S. However, forecast signal remains
   muted, introducing enough uncertainty to preclude introduction of
   any critical fire weather probabilities.
