   ...Synopsis...
   Along the northern periphery of an upper ridge extending from Mexico
   into the Southwest, a subtle midlevel impulse will advance eastward
   across the southern Great Basin and central Rockies during the day.
   As this feature and related ascent glance the northern periphery of
   a midlevel moisture plume, isolated to widely scattered high-based
   thunderstorms will form across the southern/eastern Great Basin into
   the central Rockies during the afternoon -- with a focus over the
   higher terrain features. Deep boundary-layer mixing beneath the
   midlevel moisture will yield inverted-V soundings, favorable for
   mostly dry thunderstorms capable of strong/erratic wind gusts. Given
   critically dry fuels across the region (90th-95th percentile ERCs),
   lighting-induced ignitions will be a concern.

   Day 3-8 Fire Weather Outlook  
   NWS Storm Prediction Center Norman OK
   0448 PM CDT Thu Jun 11 2026

   Valid 131200Z - 191200Z

   ...Synopsis...
   Broad upper-level troughing will remain anchored over the
   Manitoba/Ontario region on Day 3/Saturday as an upper-level ridge
   builds over the West Coast. Early next week, a shortwave trough is
   forecast to dig southward around the base of this persistent
   Canadian trough, tracking across the northern Rockies around Day
   4/Sunday. The upper-level ridge is expected to break down early to
   mid-week as an upper-level jet max strengthens and progresses ahead
   of an incoming northern Pacific trough. This secondary trough is
   projected to move onshore into the Pacific Northwest by mid-to-late
   next week, subsequently shifting the axis of the ridge eastward over
   the Great Plains.

   ...Day 3/Saturday...
   A narrow, amplified upper-level ridge will stretch across the
   western CONUS on Day 3/Saturday, while a subtle mid-level shortwave
   migrates across the Southwest. Simultaneously, a plume of mid-level
   moisture advecting northward from the Baja Peninsula will promote
   convective potential, primarily centered over the southern Great
   Basin. Given deep, dry antecedent fuel conditions resulting from
   consecutive days of hot, dry, and breezy weather, dry thunderstorms
   will pose an ignition concern across northern AZ and southern UT. A
   10% probability of dry thunderstorms continues for this area.
   Further spatial modifications to this risk area remain likely in
   upcoming outlook cycles as additional forecast guidance becomes
   available.

   ...Day 6/Tuesday through Day 7/Wednesday...
   Looking deeper into next week, the wholesale breakdown of the
   western ridge is expected to escalate fire weather concerns across
   the Intermountain West as the jet strengthens and gives way to
   another trough later next week. But first, at least 2-3 days of well
   above normal surface temperatures will occur under the established
   ridge. Daily record high temperatures could be met or exceeded in
   portions of the Pacific Northwest as this anomalous, but
   short-lived, heat wave effectively dries dead fuels over much of the
   western CONUS - significantly so over the Pacific Northwest. As the
   ridge dampens and begins to slide eastward, expect winds to
   strengthen amid the pre-existing very warm and dry conditions. Thus,
   40% Critical probabilities have been introduced over portions of the
   Great Basin and Southwest on Day 6/Tuesday and Day 7/Wednesday.
   These areas will likely require expansion when the areal extent of
   the strongest winds becomes more clear.
