   Valid 181200Z - 241200Z

   The upper-level pattern will amplify with a deep trough over the
   western CONUS with the Bermuda High building into the Southeast on
   Day 3/Monday - Day 4/Tuesday. This longwave pattern should remain
   intact until late next week/weekend. An upper-level shortwave trough
   will eject out of the West and move east-northeast across the Plains
   and into the Great Lakes region on Day 5/Wednesday - Day 6/Thursday.
   Cool/cold temperatures and precipitation will fall across much of
   the CONUS during the outlook period helping to temper the fire
   weather threat. 

   ...Day 3/Monday - Day 4/Tuesday: Portions of West Texas...
   Amid a dry, post-frontal airmass, downslope flow/lee troughing will
   result in possibly critical conditions (sustained west-southwest
   winds of 15-20 mph, RH values of 8-20%) on Day 3/Monday across
   western portions of the Trans-Pecos and southern New Mexico. As a
   shortwave trough moves across the Intermountain West, strong
   mid-level flow (65-95 knots) will overspread the southern High
   Plains again on Day 4/Tuesday. However, the strongest downslope
   flow/lee troughing will be farther south into northern Mexico east
   of the Sierra Madre Oriental with critical conditions (westerly
   sustained winds of 15-20 mph, RH values of 5-20%) possibly
   developing in the Big Bend region as a result. Critical conditions
   developing on these days hinge on the ability of downslope flow/lee
   troughing to heat/dry out the boundary layer in the cool/cold
   airmass after the frontal passage over the weekend.

   ...Day 6/Thursday - Day 8/Saturday: Southern High Plains...
   Dry/windy conditions may return to the southern High Plains late
   next week/weekend as another upper-level trough moves over the
   Intermountain West. However, there remains enough uncertainty
   regarding the timing/location of the trough to preclude
   probabilities of critical conditions at this time.
