   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE SOUTHERN GREAT
   BASIN...

   ...Synopsis...
   A large amplitude upper-level trough will move into the western
   CONUS on Wednesday. Strengthening mid-level flow around the base of
   this trough will overspread the dry airmass in the Great Basin
   Wednesday. Deep mixing during the afternoon will transport 20 to 25
   mph winds to the surface where surface relative humidity is expected
   to be around 10 to 15 percent. These conditions support a critical
   fire weather delineation in portions of the southern Great Basin. 

   In addition to these fire weather conditions, this strong
   upper-level trough will also bring significant rainfall to most of
   Oregon, Washington, and Idaho which should significantly reduce fire
   weather threat in these regions for at least a few weeks and could
   possibly serve as a season ending event for many areas, especially
   considering the significant rainfall totals across these areas
   during the past week.
