   ...Synopsis...
   Within the base of a broad/amplifying large-scale trough
   encompassing the northern CONUS, a belt of 60-70-kt midlevel
   northwesterly flow will overspread the northern/central Rockies and
   adjacent Plains on Wednesday. To the south, diurnal heating of a dry
   antecedent air mass will result in an expansive area of 10-15
   percent afternoon RH across much of the Intermountain West/Great
   Basin into the central/southern Rockies. 

   As moderate-strong deep-layer flow peripheral the primary jet stream
   overspreads this deeply mixed air mass, widespread 15-20 mph
   sustained west-northwesterly surface winds are expected. The
   combination of warm/dry conditions and these breezy/gusty winds will
   favor a large area of elevated to locally critical fire-weather
   conditions. A Critical area was considered in parts of eastern UT
   into western CO, where 20 mph sustained west-northwesterly surface
   winds should overlap 15-20 percent RH amid dry fuels, though this
   favorable overlap appeared a bit localized for the upgrade at this
   time.

   Day 3-8 Fire Weather Outlook

   0459 PM CDT Mon Jun 15 2026

   Valid 171200Z - 231200Z

   Broad upper-level troughing will persist across the northeastern
   CONUS through late this week as an upper low remains anchored over
   the southern Ontario/Quebec regions. An upper-level ridge will
   flatten over the Pacific Northwest on Day 3/Wednesday, eventually
   breaking down and shifting eastward over the central CONUS as a
   trough moves onshore the West Coast by Day 4-5/Thursday-Friday.
   Consequently, some isolated dry thunderstorm potential alongside dry
   and breezy conditions with above normal temperatures (and resultant
   dry fuels) will support expansive fire concerns through the
   remainder of the forecast period. 

   ...Day 3/Wednesday - Portions of the Great Basin, Colorado Plateau,
   and central Plains...
   The western upper ridge will dampen and slide eastward towards the
   Continental Divide as troughing moves onshore the West Coast. A
   60-70 kt jet will expand from northern MT through the Central States
   as a southward progressing surface low sends a dry cold front
   through the Great Plains. Tightening surface pressure gradients and
   post frontal west-northwesterly flow will promote dry and breezy
   conditions across the region where dry fuels exist, maintaining 40%
   Critical probabilities.

   ...Day 5-6/Friday-Saturday - Parts of the Pacific Northwest and
   Great Basin...
   As upper-level troughing moves onshore the West Coast, above normal
   temperatures are forecast across the Pacific Northwest on Day
   5/Friday. Increasing mid-level moisture and synoptic scale lift
   should bring increased chances for thunderstorms as the trough moves
   inland. Given preceding days of warm and dry conditions and
   coincident curing fuels, the isolated nature of thunderstorm
   development could pose a threat for lightning ignitions across a
   very dry environment. Fast storm motions, high cloud bases, and
   locally breezy conditions support 10% Dry Thunderstorm probabilities
   on Day 5/Friday, and again on Day 6/Saturday as the potential shifts
   eastward. Increasing southerly to westerly flow across the Southwest
   will transport very dry air and breezy conditions amid 90th
   percentile ERCs, promoting continued fire concerns in the Great
   Basin through the weekend. Spatial extent of the aforementioned risk
   areas may fluctuate as guidance is better resolved in future outlook
   cycles.
