   Day 2 Fire Weather Outlook  
   NWS Storm Prediction Center Norman OK
   0159 AM CDT Wed Jun 17 2026

   Valid 181200Z - 191200Z

   ...NO CRITICAL AREAS...

   ...Synopsis...
   A large-scale ridge will re-build over the Southwest into the Great
   Basin on Thursday, where a warm/dry air mass will remain in place.
   As a result, deep-layer flow will be weaker across the region
   compared to prior days, reducing surface wind speeds and the overall
   fire-weather risk. However, locally elevated fire-weather conditions
   will still be possible within terrain-favored/wind-prone areas
   across the Great Basin into the central/southern Rockies during the
   afternoon. 

   ...Dry Thunderstorms - Sierra...
   Over the Sierra and vicinity, a midlevel trough will begin to
   impinge on the large-scale ridge, aiding in thunderstorm development
   over the higher terrain during the afternoon. Inverted-V profiles
   will favor high-based, mixed wet-dry storms. These storms atop dry
   fuels may pose some concern for lightning-induced ignitions.
   However, the overall risk appears too localized/limited for Dry
   Thunderstorm highlights at this time. 

   ...Central NC and vicinity...
   Around 15-20 mph sustained southwesterly surface winds will develop
   across the area ahead of an approaching cold front from the west.
   These breezy/gusty winds will overlap marginally low RH (around
   35-40 percent), and given a lack of rainfall over central NC,
   locally elevated fire-weather conditions are possible.

   Day 3-8 Fire Weather Outlook  
   NWS Storm Prediction Center Norman OK
   0450 PM CDT Tue Jun 16 2026

   Valid 181200Z - 241200Z

   ...Synopsis...
   On Day 3/Thursday, an upper low will slowly slide eastward over
   southern Quebec as a belt of strong mid-level flow expands across
   the Ohio Valley into the Northeast. Simultaneously, an upper ridge
   will break down across the West owing to an approaching upper
   trough. Some isolated dry thunderstorm potential alongside dry and
   breezy conditions with above normal temperatures (and resultant dry
   fuels) will support expansive fire concerns through Day 5/Saturday.
   The trough will lose its amplitude as it traverses the Great Plains,
   transitioning western CONUS to temporary zonal flow aloft. While
   predictability is low, extended guidance exhibits increasing
   potential for ridging to build back across the Pacific Northwest,
   bringing warm and dry conditions back into the region early next
   week. 

   ...Day 3-5/Thursday-Saturday - Parts of the Pacific Northwest and
   Great Basin...
   As upper-level troughing moves onshore the West Coast, surging
   mid-level moisture and synoptic scale lift will bring increasing
   chances for thunderstorms. 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 -- possibly as early as Day 3/Thursday
   evening. The potential for thunderstorm development on Day
   3/Thursday will be reevaluated on the approaching Day 2 outlook
   cycle as higher resolution guidance becomes available. Fast storm
   motions, high cloud bases, and locally breezy conditions support 10%
   Dry Thunderstorm probabilities on Day 4/Friday, and again on Day
   5/Saturday as the trough shifts eastward. Spatial extent of the
   aforementioned risk areas may fluctuate as guidance is better
   resolved in future outlook cycles.

   Increasing southerly to westerly flow across the Southwest will
   transport very dry air and breezy conditions amid recently receptive
   fuels, promoting continued fire concerns in the Great Basin through
   the weekend. 40% Critical probabilities have been maintained on Days
   4-5/Friday-Saturday to account for this threat.
