   ...CRITICAL FIRE WEATHER AREA FOR SOUTHERN WYOMING...

   ...Synopsis...
   On D2/Thursday, a mid-level trough will become less amplified and
   bring strong quasi-zonal flow across the central and northern
   Rockies. At the surface, higher pressure will build into the Great
   Basin and surface troughing will be present in the Sacramento
   Valley.

   ...Southern Wyoming...
   Strong westerly flow will develop during the day across the area.
   Elevated to critical fire weather conditions are expected with
   surface winds of 15-25 mph and afternoon RH of 5-15%.

   ...Snake River Valley...
   While boundary-layer mixing will be weaker in this area, a strong
   enough surface pressure gradient, further enhanced by the terrain,
   is expected to produce elevated to perhaps locally critical fire
   weather conditions. Winds will generally reach 15-20 mph with
   afternoon RH of 10-15%.

   ...Portion of Sacramento Valley...
   Most guidance is in agreement that a surface trough will develop
   within the valley. With high pressure pushing in from off the West
   Coast, northerly flow should reach 15-20 mph with afternoon RH of
   5-15%.
