   Valid 131200Z - 141200Z

   ...Synopsis...
   As an upper-level low and associated 70 kt jet streak moves from the
   Pacific Northwest into the Northern Rockies on Sunday, dry and gusty
   conditions at the surface will support Elevated fire-weather
   conditions over much of the Great Basin into the Snake River Valley
   and portions of southwestern Montana. 

   ...Great Basin into portions of Idaho and Montana...
   Beneath the compact upper-level low and associated strong jet
   streak, deep boundary layer mixing will result in broad, gusty
   southwest flow of 15-20 MPH and relative humidity around 15%.
   Elevated fire-weather conditions could persist as the upper low
   progresses eastward and a relatively dry cold front moves across the
   region. Fuels guidance has ERCs generally at or below the 70th
   annual percentiles, tempering overall fire-weather concerns.

   Day 3-8 Fire Weather Outlook  
   NWS Storm Prediction Center Norman OK
   0442 PM CDT Fri Sep 11 2026

   Valid 131200Z - 191200Z

   ...Synopsis...
   An upper trough will translate east-northeastward from the Pacific
   Northwest and Northern Rockies on Day 3/Sunday into the Upper
   Midwest by Day 4/Monday. In response, broader dry west/southwest
   flow develops across portions of the Great Basin on Day 3/Sunday,
   with fire weather concerns potentially lingering into parts of the
   northern Rockies on Day 4/Monday. Another mid/upper trough enters
   the Pacific Northwest on Day 5/Tuesday, possibly bringing dry and
   breezy conditions back to the Great Basin. A stagnant upper-level
   ridge over the southern CONUS will continue to promote above normal
   temperatures across much of the southern/central Plains through next
   week. Fire weather concerns east of the Continental Divide next week
   should be confined to portions of the Southern Plains where daily
   southerly winds and dry fuels align although forecast uncertainty in
   RH reductions limits predictability of fire weather impacts.

   ...Day 3/Sunday - Great Basin into southwestern Montana...
   Pre-frontal southwest winds of 15-20 mph amid a well mixed boundary
   layer and minimum RH of around 15% will present a broad fire weather
   threat to the Great Basin into portions of ID and southwest MT on
   Day 3/Sunday. As the upper-trough and related dry cold front shift
   eastward, a west to northwest wind shift will present an additional
   fire weather hazard to existing wildfires, before cooler
   temperatures and higher RH provide some reprieve Sunday night. 40%
   critical probabilities have been added to cover this threat.

   ...Day 4/Monday...
   ...Wyoming/Northern High Plains...
   A fire weather threat may be reintroduced into portions of WY and
   the northern High Plains as the trough across the Pacific Northwest
   makes eastward progress into the Northern Plains. However, some
   uncertainty exists regarding the deeper subtropical moisture plume
   over the Four Corners and its eventual northward extent. Expanding
   leeward surface troughing across the northern/central Plains will
   promote the stronger low-level westerly flow across southern WY
   while dry and breezy conditions ahead of a cold front are possible
   across southern MT/northern WY and adjacent SD, but potential
   rainfall could mitigate these concerns.

   ...Southern Plains...
   Persistent south to southwest flow at the surface under a stagnant
   upper ridge is expected across portions of the southern Plains next
   week. Fuels across western OK and northwestern TX remain dry and
   receptive (ERCs near the 90th percentile) with minimal rainfall
   observed recently. South winds of 10 to locally 20 mph and the dry
   fuels will likely align, although forecast uncertainty in RH
   reductions each afternoon precludes introduction of critical
   probabilities for this outlook.
