   ...NO CRITICAL AREAS...

   ...20z Update...
   No changes, brief locally elevated fire-weather conditions will
   remain possible behind a cold front across parts of the northern
   Plains Saturday. However, only marginal low RH, poorly overlapped
   with the gusty winds and dry fuels suggests more widespread concerns
   are unlikely. See the previous discussion.

   .PREV DISCUSSION... /ISSUED 1158 PM CDT Thu Jun 05 2025/

   ...Synopsis...
   The upper pattern will amplify to a degree over the central/eastern
   CONUS, with a mid-level trough deepening across the northern Plains
   into the Great Lakes region as a preceding mid-level trough
   traverses the OH Valley tomorrow (Saturday). Like Day 1, a moist
   low-level airmass and/or scattered to widespread thunderstorms
   across several locales east of the Rockies should limit
   wildfire-spread potential. A cold front should sweep across the
   northern Rockies/northern High Plains tomorrow afternoon. However,
   RH is not expected to dip to Elevated/Critical thresholds. As such,
   while a localized wildfire start cannot be ruled out, conditions
   appear too marginal to warrant the introduction of fire weather
   highlights this outlook.

   Day 3-8 Fire Weather Outlook

   0500 PM CDT Fri Jun 06 2025

   Valid 081200Z - 141200Z

   Fire-weather potential over much of the CONUS is low through the
   extend forecast period. Mostly zonal mid-level flow will begin to
   transition to a more amplified state late this weekend and into
   early next week. Subtropical ridging over the western US will
   intensify forcing northwesterly flow aloft over much of the Plains.
   To the east, a broad upper trough will deepen over the eastern US as
   it moves out of Canada. With northwesterly flow aloft and troughing
   over the east, broad southerly flow and moist surface conditions
   will support widespread thunderstorms across much of the Plains,
   Midwest and eastern US. Cool and wet conditions should temper
   fire-weather concerns. Western troughing should redevelop late in
   the extended forecast period potentially allowing dry and windy
   conditions to emerge over the western US.

   ...Northern Plains/Rockies...
   As the northern stream trough begins to deepen and move south out of
   Canada, strong northwesterly flow will overspread the northern
   Rockies and Plains late this weekend and into early next week. A
   cold front moving down the Plains will usher in a drier air mass
   across parts of eastern MT and the western Dakotas D3/Sunday. While
   model guidance varies, consensus shows a few hours of dry and breezy
   conditions with post-frontal downslope flow across the northern High
   Plains. While area fuels are not overly dry, locally elevated
   fire-weather conditions are possible.

   ...Great Basin and Southwest...
   The upper ridge is forecast to weaken and shift eastward starting
   the middle of next week. This will allow some western US troughing
   to deepen and overspread the drier portions of the Great Basin and
   Southwest into next weekend. While details remain unclear due to
   model variance, increasing flow aloft, coupled with several
   preceding days of dry and warm conditions, may support increasing
   potential for fire-weather conditions. 

   Warm temperatures beneath the upper ridge, coupled with modest
   ascent and mid-level moisture from several weak subtropical
   vorticity maxima forecast to move over the Southwest could support
   isolated dry thunderstorm potential over the Southwest. While again
   details are unclear, the potential for drying fuels and lightning
   could increase over parts of the Southwest toward the end of the
   forecast period.
