   ...CRITICAL FIRE WEATHER AREA FOR THE FOUR CORNERS REGION...

   ...Synopsis...
   A highly amplified upper-level trough positioned over the Great
   Basin will shift east through the Northern Rockies into portions of
   the central/northern Plains. Enhanced mid-level flow of 60-70 kt
   will be present within the base of the trough during this
   progression. At the surface, a broad region of dry and breezy
   southwesterly winds will develop during the afternoon beneath the
   mid-level jet.

   ...Four Corners Region and portions of the central Rockies and
   central High Plains...
   Sustained winds of 15-25 mph will develop during the afternoon while
   RH values fall into the 15-20% range over much of the region. Fuels
   remain receptive to large-fire spread, and thus, elevated to
   critical fire-weather conditions are possible. Refinements were made
   to the existing elevated area over portions of the central High
   Plans and central Rockies, based on the position of moist boundaries
   as depicted in the latest high-resolution guidance. A critical area
   was added near the Four Corners region, where it appears most likely
   that critical wind/RH thresholds will be exceeded for a few hours
   during the afternoon.
