   Valid 261200Z - 011200Z

   A positively tilted mid-level trough will be developing across the 
   northern Rocky Mountains at the start of the forecast period. As
   this trough moves east Friday and Saturday, increased mid-level flow
   will glance portions of the Southwest -- particularly on Friday.
   This increased mid-level flow will be mixed down to the surface as
   strong heating results in a deep boundary layer. The result will be
   high confidence in critical fire weather conditions on Friday, with
   decreasing confidence thereafter. 

   In the wake of this trough, a large-scale ridge is expected to
   develop across the west, with an attendant trough across the east.
   This pattern will keep the strongest flow away from the dry areas of
   the west, and promote a cool, wet airmass across the east. An
   exception to the cooler/wetter airmass across the east will be
   portions of the Florida Peninsula, where relative humidity will once
   again fall below 30%. This area will need to be monitored for
   elevated-to-locally critical fire-weather concerns next week.
