   ...Synopsis...
   Preceding a deep midlevel low west of British Columbia, a belt of
   strong midlevel westerly flow will overspread the Cascades. As a
   result, locally dry/breezy downslope flow will develop in the
   Columbia Basin during the afternoon. Around 15 mph sustained
   westerly surface winds (higher in the Cascade Gaps) and 20-25
   percent RH will favor elevated fire-weather conditions.

   Day 3-8 Fire Weather Outlook

   0459 PM CDT Mon Jun 16 2025

   Valid 181200Z - 241200Z

   ...Day 3/Wednesday...
   An upper-level short wave with attendant mid-level wind maxima will
   promote breezy downslope/gap winds to the Columbia Basin where dry
   fuels remain supportive of fire spread. Meanwhile, a broad ridge
   axis roughly aligned along the Continental Divide will support above
   normal temperatures for much of the West aiding in drying fuels
   ahead of a stronger upper-level trough for the latter part of the
   week.

   ...Day 4-6/Thursday-Saturday...
   A potent upper-level trough and attendant stronger mid-level flow
   will impact the western U.S. beginning on Day 4/Thursday introducing
   a broad fire weather threat into the Great Basin and portions of the
   Southwest. Considerable southwest surface winds of 20-30 mph and
   very low relative humidity will coincide with dry fuels to promote
   wildfire spread (including potential expansion of existing wildfire
   footprints) across the region. Critical probabilities were added to
   northwestern Nevada as well as southeastern Nevada and southwest
   Utah. Primary fire weather threat expands eastward into Utah and
   western Colorado on Day 5/Friday as upper-level trough shifts/nudges
   eastward. Model guidance consensus suggests a deceleration of
   eastward advancement of main trough axis by Day 6/Saturday, allowing
   enhanced mid-level flow to remain over portions of the Four Corners
   and Southwest into the weekend, while the Pacific Northwest
   experiences some relief with cooler temperatures and some rainfall.
   In addition, dry post-frontal winds should increase the fire weather
   threat across the California Central Valley where a Critical 40
   percent probability area has been maintained.

   ...Day 7-8/Sunday-Monday...
   The multi-day fire weather event could linger into early next week
   around the Four Corners region as a troughing pattern persists
   across the Western U.S. However, decreasing mid-level flow as the
   upper-level trough diffuses should limit magnitude of winds although
   dry conditions and warm temperatures are still a high likelihood.
