   Valid 201200Z - 261200Z

   Mid-level ridging is forecast to build eastward across the western
   CONUS Day 3/Monday and into the Plains by Day 6/Thursday. While
   model uncertainty increases substantially thereafter, there is some
   potential for a mid-level trough to move across the Southwest and
   into the Plains late Day 6/Thursday or Day 7/Friday into next
   weekend. At the surface, persistent lee troughing across the
   central/southern High Plains will maintain downslope flow with
   dry/breezy conditions most days through the extended forecast
   period.  

   ...Southern/Central Plains...
   The presence of modestly enhanced mid-level flow alongside a dry
   low-level air mass and critically receptive fuels suggests at least
   locally elevated fire weather conditions will be possible across
   some portion of the southern/central Plains Day 4/Tuesday into Day
   6/Thursday. Fire weather concerns may increase Day 7/Friday or Day
   8/Saturday, as stronger flow aloft overspreads the area in
   association with the aforementioned mid-level trough. At this time,
   model uncertainty regarding the evolution of the mid-level trough is
   too large to introduce Critical fire weather probabilities.
   Nevertheless, the lack of forecast precipitation through the
   extended (and beyond) suggest this area will need to be monitored
   closely for favorable overlaps of wind/rh as fuels will remain
   critically dry.
