   Valid 221200Z - 281200Z

   A closed upper-level low located over southern California and lower
   Nevada will quickly weaken on Day 3/Tuesday, transitioning to an
   open/weak trough by Day 4/Wednesday while lifting northeast toward
   the northern Rockies. Some enhancement to the mid-level flow will
   accompany this feature along its southern periphery as it undergoes
   the aforementioned evolution. Generally weak upper-level flow looks
   to settle in for the remainder of the forecast period, with perhaps
   some signal of a trough entering the West Coast toward the end of
   the period.

   ...Day 3/Tuesday and Day 4/Wednesday: Portions of the Southwest...
   Warm and dry conditions will prevail across eastern Arizona and
   western New Mexico for most of the forecast period, but the best
   chance for seeing breezy conditions, and thus elevated fire
   concerns, is on Day 3/Tuesday and Day 4/Wednesday. Mid-level
   southwesterly winds of 30-35 kt will accompany the western closed
   low/trough, and with diurnal heating these winds should mix toward
   the surface. Thus, the 40%/marginal probabilities have been
   maintained across the region, with a slight westward expansion made
   on Day 4/Wednesday. In addition, there is some potential for locally
   critical conditions to develop on Day 3/Tuesday across east-central
   Arizona and west-central New Mexico, along with potential for
   isolated dry thunderstorms across central New Mexico. There is too
   much uncertainty the placement and evolution of these risks to
   warrant any highlights at the current time.

   Thereafter, the lack of appreciable mid-level flow should temper
   fire-weather concerns despite hot/dry conditions remaining in place
   across portions of the Southwest.
