   Day 2 Fire Weather Outlook

   Valid 271200Z - 281200Z

   The main change to the Day 2 Fire Weather Outlook Update was to
   expand isolated dry thunderstorm highlights westward to include
   portions of western Idaho into eastern Oregon. The lack of
   upper-level support and shallow buoyancy suggests that thunderstorm
   development in these areas should be more sparse compared to places
   farther east. Still, fuel beds in these areas remain receptive to
   fire spread wherever dry strikes may occur, necessitating the
   expanse of isolated dry thunderstorm highlights this outlook.
   Otherwise, the previous forecast (see below) remains on track.

   .PREV DISCUSSION... /ISSUED 0158 AM CDT Fri Jul 26 2024/

   ...Synopsis...
   As a mid-level trough progresses eastward from California into the
   northern Great Basin on Saturday, isolated dry thunderstorms are
   expected across portions of eastern Idaho, southwestern Montana,
   western Wyoming, and portions of far northern Utah. This trough is
   also expected to bring dry and windy conditions to much of southern
   Nevada into southwestern Utah. 

   ...Dry Thunder...
   An approaching trough from California is expected to bring chances
   for isolated dry thunderstorms to portions of Idaho, Montana,
   Wyoming, and Utah. Recent wetting rainfall could potentially limit
   some lightning ignitions, but pockets of receptive fuels still
   remain across much of the highlight area. Dry boundary-layer
   profiles will support gusty thunderstorm outflow that could
   contribute to wildfire spread with any lightning based ignitions. 

   ...Southern Great Basin...
   Relative humidity of 5-10% and wind speeds of 25-30 MPH are expected
   across southern Nevada into southwestern Utah, exceeding the
   meteorological criteria for critical conditions. However, there is
   uncertainty in the receptiveness of fuels to wildfire spread due to
   recent significant wetting rainfall, precluding the inclusion of
   critical highlights at this time.

   Day 3-8 Fire Weather Outlook  
   NWS Storm Prediction Center Norman OK
   0341 PM CDT Fri Jul 26 2024

   Valid 281200Z - 031200Z

   Multiple mid-level impulses will traverse the northwestern U.S. Days
   3-5 (Sunday-Tuesday) before upper riding builds over the western and
   central CONUS through most of next week. The passing mid-level
   impulses will encourage dry and occasionally breezy conditions
   across areas east of the Cascades into the Great Basin. The best
   chance for Elevated equivalent meteorological surface conditions
   will be over southeast Nevada into Utah on Sunday, where 40 percent
   Critical probabilities have been introduced. These conditions may
   persist into Monday across the same areas, as well as the lee of the
   Cascades with the progression of a mid-level impulse. A stray dry
   thunderstorm or two may also occur ahead of this impulse across the
   northern Rockies somewhere in the Monday-Tuesday time frame, though
   coverage and available buoyancy appears too marginal for dry
   thunderstorm probabilities this outlook. Relatively quiescent fire
   weather conditions are expected through the rest of next week across
   the Interior West as mid-level impulses clear the region and upper
   ridging becomes established.
