   Valid 051200Z - 061200Z

   The existing Elevated Wind/RH area was expanded to include central
   and southeastern WY where weak to moderate lee side winds (sustained
   at 15-20 mph) will impact portions of western, central, and
   southeastern WY. These winds will be coincident with above normal
   temperatures supporting deep-mixing and afternoon RHs near 10-20%
   over eastern WY. Though dead fuels are less dry over this region,
   the increased winds amid warm and dry conditions will support some
   fire weather threat.

   ...Synopsis...
   A mid-level jet will move across parts of the northern Rockies
   during the afternoon. This feature will promote increased downslope
   winds, particularly in the lee of the terrain, behind a surface
   trough farther to the east. Winds near the terrain will be 15-20 mph
   with locally higher speeds possible. RH will fall to 15-20% given
   the unseasonably warm temperatures. Elevated fire weather can be
   expected for a few hours on Monday.

   Day 3-8 Fire Weather Outlook

   Valid 061200Z - 121200Z

   A lingering upper-level ridge will undergo further suppression on
   Day 4/Wednesday and Day 5/Thursday as the upper-level jet continues
   to dive southward along its northeastern periphery. This pattern
   looks to fully break down the high as yet another higher-amplitude
   trough approaches the Pacific Northwest on Day 6/Friday. Forecast
   guidance currently indicates that this system will introduce
   increased winds, but also usher in cooler temperatures and
   precipitation chances over the Pacific Northwest and Northern
   Rockies primarily on Day 7/Saturday and Day 8/Sunday.

   On Day 7/Saturday, the pressure gradient will begin to tighten ahead
   of the aforementioned upper-level trough moving southeastward into
   the Pacific Northwest. Southwesterly flow ahead of this impending
   trough is likely to support widespread strong surface winds
   (sustained near 20 mph) amid above normal temperatures and dry
   afternoon RHs near 10-20%. After several days of dry conditions and
   above-normal temperatures through the coming week, fuels will be
   conditioned for ignition across much of the central latitudes of the
   western CONUS as this wind event approaches. Thus, an area of 40%
   probability of Critical Wind/RH conditions have been introduced over
   much of eastern and southern WY on Day 7/Saturday. Further expansion
   may be necessary as the pattern evolution becomes more clear.
