   Valid 271200Z - 281200Z

   No significant changes were made to the previous outlook.
   Progressively drier and intensifying deep layer south-southwest flow
   over the Great Basin is still expected through D2/Sunday as an
   amplifying upper trough pushes into OR/CA. South-southwesterly
   surface winds of 15-20 mph (localized 25 mph) and RH as low as 10%
   will align across parts of the Great Basin by peak afternoon
   heating. The dry and breezy conditions atop sufficiently receptive
   fuels should support an Elevated fire weather threat for several
   hours on Sunday for portions of central/eastern NV.

   .PREV DISCUSSION... /ISSUED 1240 AM CDT Sat Sep 26 2026/

   ...Synopsis...
   Further amplification of a western CONUS trough will result in the
   development of a closed midlevel low over central CA on Sunday.
   Preceding this feature, deep-layer south-southwesterly flow will
   strengthen across portions of the Great Basin, with boundary-layer
   mixing yielding sustained south-southwesterly surface winds of 15-20
   mph amid 10-15 percent RH. These dry/breezy conditions, combined
   with at least modestly receptive fuels across portions of
   central/eastern NV, will result in elevated fire-weather conditions.

   Day 3-8 Fire Weather Outlook  
   NWS Storm Prediction Center Norman OK
   0434 PM CDT Sat Sep 26 2026

   Valid 281200Z - 041200Z

   ...Synopsis...
   An upper-level low cut off from stronger westerly flow along the
   northern tier states will gradually progress eastward from the Great
   Basin D3/Monday reaching the southern/central Plains through
   D6/Friday. Additionally, abundant remnant moisture from tropical
   cyclone activity in the northeast Pacific will be transported
   northeastward into the Southwest and eventually the central/southern
   Plains through the week. The eastward progressing low along with
   ample atmospheric moisture should result in widespread wetting
   rainfall across the Southwest and much of the Great Plains, muting
   fire weather concerns. Farther north, an embedded mid-level short
   wave should promote a fire weather threat to north-central MT on
   D4/Tuesday as stronger westerly winds develop. Dry and breezy
   conditions could return to portions of northeastern CA and
   northwestern Great Basin sometime late next week as an upper trough
   enters the Pacific Northwest, but forecast uncertainty in timing and
   magnitude limits predictability for this outlook.

   ...Day 4/Tuesday - North-central Montana...
   An embedded wave within 50-60 knot mid-level westerly flow across
   U.S./Canada border will pass through MT D4/Tuesday. Enhanced west
   winds of 15-20 mph and downslope drying should support a fire
   weather concern for portions of north-central MT Tuesday where
   recent rainfall deficits and drier fuels exist. 40% critical
   probabilities were added to highlight this threat.

   ...Day 3-5/Monday-Wednesday - Southern California...
   The upper low across the Southwest will translate east as weak
   ridging (and related surface high pressure) builds into the
   Intermountain West through midweek. This should support a period of
   dry, offshore flow across southern CA beginning late Day 3/Monday
   with a diminishing surface pressure gradient heading into Day
   5/Wednesday. However, fuels remain marginal across the region which
   would attenuate impact from the dry and breezy conditions,
   precluding introduction of critical probabilities.
