   ...NO CRITICAL AREAS...

   Locally elevated fire weather conditions are possible on Day
   2/Saturday across central-northern Wyoming. While less widespread as
   compared to Day 1/Friday, sustained southwesterly 10-20 mph winds
   and RH values of 15-20% may overlap areas of receptive fuels;
   however, the limited duration and spatial extent of meteorological
   conditions precludes Elevated highlights. In southern Nevada and
   western Utah, southerly winds of 15-20 mph will coincide with RH
   values of 15-20%. These meteorological conditions will overlap a
   broadly less receptive fuelscape (60-80th percentile ERCs), also
   limiting an introduction of Elevated highlights.

   .PREV DISCUSSION... /ISSUED 1257 AM CDT Fri Sep 04 2026/

   ...Synopsis...
   Similar to Friday, upper-level troughing will persist across the
   Pacific Northwest, bringing cloud cover, cooler temperatures, and
   chances for rain. Upper-level ridging will also remain centered over
   the southern Great Plains, with modestly strong southwesterly flow
   aloft continuing over much of the Great Basin, northern Rockies, and
   northern High Plains. This troughing pattern and attendant
   precipitation are expected to largely mitigate fire weather concerns
   across the western U.S. for Day 2/Saturday. Elsewhere, upper
   troughing remaining over the Northeast along with a surface frontal
   system will continue to bring chances for rain to portions of the
   Midwest and East Coast.

   ...Great Basin into Central Wyoming...
   Dry, southwesterly surface flow will be maintained across the
   eastern/southeastern portions of the Great Basin and into portions
   of central Wyoming on Saturday. Locally elevated fire weather
   conditions may manifest across locations where recent rainfall
   was minimal and/or where pockets of dry fuels remain. Generally
   marginal fuels across this region are expected to preclude a broader
   fire weather risk at this time, however. While fuels are more
   receptive across portions of central Wyoming, confidence in an
   extended period (3+ hours) of overlap between 15+ mph surface winds
   and RH below 20% is lower compared to areas farther southwest.

   Day 3-8 Fire Weather Outlook  
   NWS Storm Prediction Center Norman OK
   0421 PM CDT Fri Sep 04 2026

   Valid 061200Z - 121200Z

   ...Synopsis...
   An upper-level trough bringing much of the northwestern U.S. cooler
   temperatures, cloud cover and rain will linger through the weekend,
   ejecting into the northern High Plains by Day 5/Tuesday. Subtropical
   moisture advecting into the Desert Southwest and Great Basin on Days
   3-4/Sunday-Monday will likely bring additional cloud cover and some
   rain to this region. This troughing pattern and attendant
   precipitation will largely mitigate fire weather concerns in the
   western U.S. through the middle of next week. Hot and dry conditions
   under a persistent upper ridge over the central CONUS are expected
   through the weekend, although accompanied by relatively light
   surface winds.

   ...Northern High Plains...
   As the aforementioned upper trough translates northeastward this
   weekend, advecting subtropical moisture will provide opportunities
   for rainfall across the north-central states. Despite cooler daytime
   temperatures, a drier airmass and strong southwesterly flow aloft
   could bring fire weather concerns back into portions of
   central-eastern Wyoming on Days 4-5/Monday-Tuesday. Critical
   probabilities have been withheld due to uncertainty in cloud cover
   and potential impacts from much anticipated precipitation, but may
   be needed in future outlook cycles where forecast meteorological
   conditions overlap rainfall-neglected fuels.

   ...Southern Plains...
   Beneath an accelerating upper-level trough and attendant mid-level
   jet, a surface low should evolve across the Northern Plains on Days
   4-5/Monday-Tuesday. The increasing pressure gradient will likely
   enhance southerly winds across the central and southern Plains where
   fuels remain very dry (forecast ERC values in the 90-95th percentile
   range amid areas of severe to extreme drought). This could pose a
   fire weather threat to portions of the central/southern Plains where
   rainfall deficits and cured/receptive fuels persist. However,
   forecast uncertainty in RH reductions and degree of a drier,
   downslope-enhanced southwesterly flow precludes introduction of
   critical probabilities at this time.
