   Valid 251200Z - 021200Z

   A mid-level trough will move east across the central and eastern
   CONUS Days 3-4/Tuesday-Wednesday, with surface high pressure and
   associated cooler temperatures sweeping across much of the CONUS. A
   second mid-level impulse is expected to pivot around the backside of
   the larger-scale trough, reinforcing high pressure across the
   central U.S on Day 5/Thursday. Thereafter, medium-range guidance
   depicts a mid-level ridge traversing the western and central CONUS
   on Days 6-7/Friday-Saturday, with a mid-level trough amplifying
   across the southwest CONUS and a surface low developing across the
   central Plains Day 8/Sunday.

   ...Day 3/Tuesday...
   With high pressure overspreading much of the Inter-mountain West, a
   tight pressure gradient will develop across southern California. Dry
   and breezy offshore flow is expected throughout the day, though
   marginally receptive fuels and recent rainfall are expected to
   mitigate large-scale wildfire spread.

   Meanwhile, the southerly surge of a cooler airmass across the
   southern High Plains will promote windy, dry conditions across
   southern New Mexico into Far West Texas by afternoon peak heating.
   Some slight disagreement among short-term model members regarding
   where the best overlap of favorable wind/RH will be. Given model
   disagreement and marginally receptive fuels across the region,
   critical probabilities will be withheld, though an elevated area may
   be needed in future outlooks.

   ...Day 4-8/Wednesday-Sunday...
   Though cooler temperatures will prevail across much of the southern
   High Plains through the remainder of the period, dry and breezy
   conditions, combined with a relative lack of forecast accumulating
   precipitation, will encourage the curing of finer fuels. Towards
   next weekend (Days 7-8), strong and dry southwesterly flow will
   return to the High Plains with the onset of lee troughing and
   subsequent low development in the central Plains. Still, model
   guidance differs regarding the placement of critical wind/RH
   overlap, and conditions will continue to be monitored for the need
   of critical probabilities in later outlooks.
