   details.

   ...Synopsis...
   A robust upper-level trough will enter the Pacific Northwest
   D2/Friday. At the surface, a cold front progresses southeastward
   reaching the Northern Rockies and Great Basin by late Friday.
   Enhanced southwest winds prior to frontal passage will promote fire
   weather concerns for northern NV into bordering OR/ID.

   ...Northern Nevada, far southeastern Oregon and southwestern
   Idaho...
   A 60-70 knot mid-level jet will shift over southeastern OR as the
   upper trough pushes into the Pacific Northwest. The resultant deep
   layer southwesterly flow bolstered by surface troughing stretching
   from the Northern Rockies to the Great Basin will encourage
   southwest winds of 15-20 mph (locally 25 mph) across portions of the
   northern Great Basin. Minimum daytime RH within a well-mixed
   boundary layer could reach 10-15% prior to frontal passage. Elevated
   fire weather concerns are likely to evolve within the dry and breezy
   conditions where adequately dry fuels exist over northern Northern
   Nevada, far southeastern Oregon and southwestern Idaho. Gusty
   post-frontal west/northwest winds could bring a secondary risk to
   any potential wildfires but rising RH within the cooler air mass
   will limit impact duration.

   Day 3-8 Fire Weather Outlook  
   NWS Storm Prediction Center Norman OK
   0415 PM CDT Thu Sep 24 2026

   Valid 261200Z - 021200Z

   ...Discussion...
   A coastal low will continue to strengthen just off the Mid-Atlantic
   coast, bringing gusty surface winds and precipitation chances across
   New England this weekend. Meanwhile, an upper shortwave trough will
   lift out of the Northern Rockies and into the Canadian Prairies.
   Upper winds will moderate slightly on Day 3/Saturday, though an
   emerging 30-40 kt 700 mb jet will maintain dry and breezy conditions
   across portions of the Great Basin through Day 4/Sunday. The
   expected overlap of sustained southerly 15-20 mph winds and near 15%
   RH would typically increase fire weather concerns, but such
   meteorological conditions will overlap a region of marginal fuels;
   thus, precluding Critical probabilities at this time. 

   Predictability wanes into early next week with ambiguity in the
   progression of the overall pattern; however, the development of
   deeper troughing over the western CONUS may induce an offshore flow
   regime in Southern California on Days 5-6/Monday-Tuesday.
   Additionally, some tropical influence from Hurricane Polo could
   bring increased moisture to the southwestern CONUS early next week.
