   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF NORTHWEST NEVADA...

   ...19z Update...
   Overall the prior forecast remains on track. Model consensus has
   trended toward stronger winds (15-25 mph) and lower humidity in the
   lee of the Cascades Friday. This will support widespread elevated,
   and several hours of critical fire-weather concerns across northwest
   and western NV. Have added a small critical across northwest NV
   where the best overlap of dry/breezy conditions and supportive fuels
   will occur.

   .PREV DISCUSSION... /ISSUED 1145 PM CDT Wed Jun 11 2025/

   ...Synopsis...
   A mid-level trough will impinge on the northern Rockies while upper
   ridging becomes established across the Plains toward the
   Appalachians tomorrow (Friday). The passage of the Northern Rockies
   trough will encourage yet another day of dry downslope flow to the
   lee of both the Cascades and Sierra by afternoon. 15-20 mph
   sustained westerly surface winds will overlap with 15-20 percent RH,
   atop dry fuels, for several hours Friday afternoon, warranting
   Elevated highlights.

   Day 3-8 Fire Weather Outlook

   Valid 141200Z - 201200Z

   Strong flow aloft over much of the western CONUS is expected through
   the forecast period as sub-tropical ridging shifts eastward. This
   will favor dry surface conditions and increasingly strong wind
   fields across the Great Basin and lee of the Cascades. Additionally,
   isolated thunderstorms are possible through this weekend and into
   next week. Fire-weather conditions are expected to increase through
   next week.

   ...Northwest and Great Basin...
   Westerly mid-level flow will continue over the Northwest and Great
   Basin this weekend and much of next week. Dry downslope winds are
   likely D3/Saturday atop drying fuels. With westerly downslope flow
   of 15-20 mph overlapped with RH below 20%, elevated fire-weather
   conditions are likely in the lee of the Sierra and through the
   western Columbia Basin. Some localized threat may persist in the lee
   of the Sierra and Cascade Gaps D4/Sunday. 

   The strongest winds aloft are likely to coincide with the passage of
   several stronger embedded shortwaves passing through next week. The
   most significant of these appears to be D5/Monday. More widespread
   winds of 20-30 mph with RH below 20% are likely across the western
   and central Great Basin. However, fuels farther south are less
   receptive. This casts some uncertainty on how widespread
   fire-weather concerns will be early next week. Still, enhanced
   mid-level flow and favorable fire-weather pattern will likely
   continue through the remainder of the extended forecast period.

   ...Dry Thunderstorms...
   Continued troughing over the West will support isolated thunderstorm
   chances late this weekend and into early next week across the
   northern Great Basin and Northwest. Weak inland transport of
   mid-level Pacific moisture should support weak buoyancy with very
   dry surface conditions. Isolated lightning and a few drier storms
   are possible, especially D5/Monday and D6/Tuesday. Thereafter, more
   wetting rainfall appears likely across the Northwest as a cold front
   approaches.
