   Valid 111200Z - 121200Z

   ...Synopsis...
   An upper-level trough will remain in place across much of the
   western U.S. on D2/Sunday, aiding in the northward transport of
   deeper tropical moisture into southern California and much of the
   Intermountain West. At the surface, a frontal system will extend
   from southern California northeastward into the Great Basin and then
   eastward into the central Plains. In the wake of this front, mainly
   dry conditions will continue across the Columbia Basin and northern
   California, with dry and breezy northerly flow expected to bring an
   elevated fire weather threat to the northern Sacramento Valley
   Sunday afternoon.

   ...Northern Sacramento Valley...
   Following Saturday's cold frontal passage, strengthening northerly
   winds and dry conditions are expected to support an increasing fire
   weather threat for portions of the northern Sacramento Valley and
   adjacent foothills. Sustained northerly winds of 15-25 mph (with
   locally higher gusts) are forecast to overlap minimum RH values
   around 20% Sunday afternoon, with the gusty winds the primary driver
   of fire weather concerns where fuels are receptive.

   Day 3-8 Fire Weather Outlook

   0438 PM CDT Fri Oct 09 2026

   Valid 111200Z - 171200Z

   ...Synopsis...
   An upper-level trough will deepen across the western U.S. while
   aiding in the northward transport of deeper remnant tropical
   moisture into southern CA and much of the Intermountain West through
   D4/Monday. The resultant precipitation from the moisture-laden
   mid/upper trough across the West will tame fire weather concerns
   across southern CA and the Intermountain West. Mainly dry conditions
   will persist across the Columbia Basin southward into northern CA
   where dry, post-frontal northerly flow could bring a fire weather
   threat to the northern Sacramento Valley on D3/Sunday. Farther east,
   widespread rainfall from the remnants of Hurricane Isaias will
   similarly reduce fire weather concerns next week for the Southeast.
   Areas of receptive fuels in the lower Mississippi River Valley and
   Midwest are expected to remain in place through the middle of next
   week as above normal temperatures linger across the region. However,
   lighter surface winds under a prominent upper ridge will mitigate
   fire weather threat across this region. 

   ...Day 3/Sunday - Northern Sacramento Valley...
   Increasing northerly winds in a dry, post-frontal environment should
   facilitate an increasing fire weather threat for portions of the
   northern Sacramento Valley and adjacent foothills on D3/Sunday.
   Sustained north winds of 15 mph to locally 20-25 mph with higher
   gusts should evolve late D2/Saturday into D3/Sunday. Although much
   cooler temperatures behind the front could limit RH reductions to
   around 20% by Sunday afternoon, the gusty north winds will be a more
   pronounced driver of fire weather concerns where fuels are
   receptive. Introduced 40% critical probabilities for the northern
   Sacramento Valley and adjacent western foothills to cover this
   threat.
