   ...Synopsis...
   A compact midlevel trough will track eastward across the Northwest
   during the day -- in tandem with a robust midlevel trough/low moving
   eastward from British Columbia into Alberta. Large-scale ascent
   preceding the midlevel trough moving across the Northwest will
   promote another day of isolated high-based thunderstorms -- with a
   focus over southeastern OR into southwestern ID. Deep inverted-V
   soundings and PW around 0.7 inches will favor dry thunderstorms
   capable of producing lightning-induced ignitions and strong/erratic
   outflow winds. 

   Similar to Day 1/Tuesday, a belt of strong deep-layer westerly flow
   (peripheral to the midlevel trough) across the Cascades will lead to
   breezy/gusty westerly surface winds in the Columbia Basin. While
   increasing boundary-layer moisture will limit RH reductions compared
   to Day 1/Tuesday, stronger surface winds will offset this and still
   yield elevated fire-weather conditions. 

   Over the Great Basin, moderate midlevel southwesterly winds
   accompanying the compact midlevel trough will overspread the Great
   Basin during the day. Deep boundary-layer mixing into this
   strengthening flow aloft will support another day of elevated to
   locally critical fire-weather conditions, given increasingly
   dry/receptive fuels.

   Day 3-8 Fire Weather Outlook

   0500 PM CDT Mon Jul 07 2025

   Valid 091200Z - 151200Z

   ...Day 3/Wednesday...
   Stronger west winds with the arrival of a mid-level short wave
   trough and attendant cold front are expected across the Columbia
   Basin where fuels remain dry. Although cooler temperatures and
   slightly higher humidity arrive with the cold front, sustained west
   winds of 15-25 mph will continue to support a fire weather threat
   amid dry fuels across the Columbia Basin. A mid-level short wave
   trough will translate over a broad ridge situated over the
   Southwestern U.S. Collocation of ascent ahead of a mid-level jet max
   and antecedent mid-level moisture should support isolated
   thunderstorms with limited rainfall across southeastern
   OR/southwestern ID on Day 3/Wednesday. The accelerated mid-level
   flow on the southern periphery of the aforementioned short wave
   along with a deep/well-mixed boundary layer will promote elevated
   west-southwest winds across much of the Great Basin and portions of
   southern Idaho. The breezy and very dry conditions support at least
   a 40% probability for critical fire weather conditions across the
   region amid an expected dry fuelscape.

   ...Day 4/Thursday...
   The mid-level short wave edges eastward into the Southern Rockies
   bringing elevated west winds to the Intermountain West and great
   Four Corners region Day 4/Thursday. A 40% probability for critical
   fire weather was introduced into southern UT and northern AZ where
   fuels will go under several days of drying through midweek, becoming
   more receptive to wildfire spread.

   ...Day 5-8/Friday-Monday...
   Building heat is expected across much of the Western U.S. through
   the weekend under an expanding mid-level ridge over southern CA
   which will promote a limited wind threat across the region. Monsoon
   moisture and associated thunderstorms will remain confined to
   southern AZ and NM through the weekend.
