U.S. Day 1 Fire Weather Outlook

   Day 1 Fire Weather Outlook  
   NWS Storm Prediction Center Norman OK
   1252 AM CDT Tue Jul 14 2026

   Valid 141200Z - 151200Z

   ...Synopsis...
   Broad ridging aloft will encompass much of the northern CONUS,
   promoting hot, dry conditions across portions of the Northern Plains
   and Upper Midwest. A surface trough extending northeastward into the
   western Dakotas will facilitate stronger low-level winds within the
   very dry air mass, heightening fire weather concerns across portions
   of the northern High Plains into central WY and north-central CO
   this afternoon. A mid-level trough approaching the Pacific Northwest
   along with a more restricted/peripheral monsoon moisture pool, will
   support isolated dry thunderstorms across the more complex terrain
   of northern CA into OR and far northwestern NV this afternoon.

   ...Northern High Plains and Central Wyoming...
   A broad subsidence regime in place across the central U.S. evidenced
   by recent water vapor satellite imagery will sustain very warm and
   dry conditions today while supporting well above normal temperatures
   for the Northern Plains. A surface trough will promote increasing
   southeast winds of around 15 mph across portions of the northern
   High Plains amid RH as low as 10 percent by peak heating. These
   conditions combined with critically dry fuels (ERCs in the 95-98th
   percentile range) will yield elevated fire weather conditions this
   afternoon. The wind direction veers to the east across central
   Wyoming amid a similarly dry fuelscape and low RH environment. A
   minor expansion of elevated highlights was warranted based on latest
   forecast guidance.

   ...Southern and Central Oregon into portions of northeastern 
   California and northwestern Nevada...
   A plume of deeper monsoon moisture over the western Great Basin and
   Sierra Nevada will arc northward around the western edge of the
   mid-level ridge through early morning, reaching the Northern Rockies
   this afternoon. Peripheral moisture, with precipitable water values
   tapering off to 0.70" closer to the Cascade Crest will remain across
   portions of central OR into northern CA. An upper trough impinging
   upon the Pacific Northwest along with afternoon instability will
   promote isolated dry thunderstorms across northern CA and southern
   OR. Latest CAM guidance suggests a threat of nocturnal convection,
   lingering into early Wednesday morning, along and east of the OR
   Cascades as a subtle embedded wave accelerates northward across the
   region. Isolated dry thunderstorm highlights were expanded as far
   north as the Columbia River Gorge where fuels are incrementally more
   receptive. Anomalously high atmospheric moisture should support
   higher probabilities of wetting rain cores across eastern OR and
   northwest NV with precipitable water values ranging from 1.2-1.4".
   Thus, trimmed the eastern extent of isolated dry thunderstorm threat
   to account for expected mitigating rainfall.

U.S. Day 2 Fire Weather Outlook

   Day 2 Fire Weather Outlook  
   NWS Storm Prediction Center Norman OK
   1255 AM CDT Tue Jul 14 2026

   Valid 151200Z - 161200Z

   ...Synopsis...
   An expansive mid-level ridge will remain over the central U.S. as a
   surface trough lingers across the northern Plains, bringing another
   day of fire weather concerns to parts of the northern High Plains
   via dry and breezy conditions. Gusty onshore winds across the
   California Coastal Ranges into the Central Valley will promote a
   fire weather threat Wednesday as fuels continue to dry.

   ...Central California Coastal Ranges and Central Valley...
   Onshore flow aided by downslope drying and terrain accelerated winds
   will support elevated fire weather conditions across the central CA
   coastal ranges into the adjacent Central Valley. Fuels continue to
   dry with ERC values reaching the 90-95th percentile range under very
   warm temperatures. These winds generally from the west and northwest
   at 10-15 mph (locally 20-25 mph in favored terrain gaps) combined
   with RH of 15-20% in the coastal ranges to as low as 10% in the
   Central valley, will support elevated fire weather conditions
   Wednesday afternoon and early evening. 

   ...Northern High Plains...
   Hot and dry conditions under a stagnant mid-level ridge over the
   central U.S. are expected across portions of the northern Plains
   Wednesday. At the surface, a trough over southeastern MT will
   bolster low-level southeasterly flow (up to 15 mph sustained) over
   portions of western SD, NE Panhandle and northern CO. These winds
   coinciding with RH in the 15-20% range will yield elevated fire
   weather conditions amid very dry fuels Wednesday afternoon. Elevated
   highlights were extended into central WY given latest forecast
   guidance with expected RH as low as 10 percent and steady easterly
   winds.

U.S. Day 3-8 Fire Weather Outlook


   ZCZC SPCFWDD38 ALL
   FNUS28 KWNS 132054

   Day 3-8 Fire Weather Outlook  
   NWS Storm Prediction Center Norman OK
   0354 PM CDT Mon Jul 13 2026

   Valid 151200Z - 211200Z

   ...Synopsis...
   A strong upper high will persist over the central/northern Plains
   through the end of this week into the early weekend. Upper-level
   troughing will continue near and off the Pacific Northwest coast
   with monsoonal moisture streaming northward across much of the
   Intermountain West this week; meanwhile, daily monsoonal
   thunderstorms are likely across the Southwest into the Great Basin.
   An upper-level trough is forecast to move near/into the Pacific
   Northwest early Day 4/Thursday, potentially suppressing moisture
   south and eastward. However, model spread and ambiguity in the
   spatial extent/strength of troughing yields significant uncertainty
   in the progression of the upper pattern across the West. Farther
   east, a deep upper-level trough is expected to weaken the ridge over
   the Great Lakes and Northeast as it digs southward on Days
   2-3/Tuesday-Wednesday, leading to unsettled conditions across the
   region through the remainder of the forecast period.

   ...Central to northern High Plains...
   Hot, dry, and breezy conditions are likely across portions of
   eastern Wyoming, western South Dakota, western Nebraska and eastern
   Colorado on Day 3/Wednesday through at least Day 4/Thursday. While
   RH is expected to recover overnight, south-southeast winds are
   likely to remain breezy amid dry fuels and hot daytime temperatures.
   40% Critical probabilities have been maintained; however, may need
   to be confined in future outlooks as predictability increases in the
   evolution of the upper pattern. 

   ...Portions of northeastern California and the Central Valley,
   western Great Basin, and far south-central Oregon...
   Warm daytime temperatures and low RH will contribute to drying fuels
   across the California Coastal Ranges into the Central Valley. ERCs
   are forecast to approach the 90-95th percentile mid-late week amid
   dry and breezy conditions, supporting any new ignitions and the
   emergence of lightning holdovers from wet/dry thunderstorms early in
   the forecast period. 40% Critical probabilities remain on Days
   3-4/Wednesday-Thursday to account for this threat. Farther north,
   guidance has backed off on the timing of stronger winds overlapping
   low RH, resulting in 40% Critical probabilities being removed on Day
   3/Wednesday across northeastern California and adjacent areas. Yet,
   the potential for stronger flow amid a returning dry airmass on Day
   4/Thursday warrants the introduction of 40% Critical probabilities.
