Day 1 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
1254 AM CST Wed Feb 20 2019

Valid 201200Z - 211200Z

...Synopsis...
As a well-defined mid-level trough exits the Central Plains and
traverses the Great Lakes area during the day, a second mid-level
shortwave trough will deepen across the southwest CONUS, with a weak
surface lee trough developing along the High Plains during the
afternoon hours. Breezy, dry surface westerlies will become
prevalent across the southern High Plains by noon, fostering modest
potential for fire spread given drying fine fuels in place.

...Portions of eastern New Mexico into west Texas...
As temperatures rise above 50F with the onset of diurnal heating and
associated boundary-layer mixing, westerly surface winds will
increase to 15+ mph, coincident with 10-20% RH. These elevated
conditions will first be realized shortly after noon east of the
Caprock Escarpment, with elevated conditions becoming more apparent
across the Llano Estacado a few hours later. By evening, nocturnal
cooling will promote surface RH recoveries and weakening winds,
lessening the wildfire threat.

...CRITICAL FIRE WEATHER AREA FOR SOUTHEAST NEW MEXICO INTO FAR
SOUTHWEST TEXAS...

...Synopsis...
As a mid-level shortwave trough continues to deepen across the
southwest CONUS, surface troughing will intensify across the
southern High Plains on Day 2/Thursday. The net result will be
relatively strong, dry westerly surface winds across parts of
southern/eastern New Mexico into far west Texas, where a lack of
past rainfall, absence of forecast rainfall, and drying fine fuels
will all coincide to promote an environment favorable for wildfire
potential.

...Southern New Mexico into west Texas...
Sustained westerly winds, with speeds exceeding 15 mph, amidst
15-20% RH, are expected across much of southern/eastern New Mexico
into west Texas during the afternoon hours, hence the elevated
delineation. Enhanced downslope flow along the lee of the Sacramento
Mountains may promote 20+ mph winds, with slightly lower RH,
warranting a critical delineation for this area per latest model
guidance. By nightfall, cooler temperatures will prevail, with RH
recovery and weaker winds expected, lowering the wildfire spread
threat for the remainder of the period.
