   ...CRITICAL FIRE WEATHER AREA FOR SOUTHEAST NM/SOUTHWEST TX...
   
   ...SYNOPSIS...
   STRONG UPPER TROUGH/ASSOCIATED JET STREAK WILL SPREAD EASTWARD OVER
   THE SOUTHERN ROCKIES AND CENTRAL/SOUTHERN PLAINS THROUGH TONIGHT.
   ACCORDINGLY...VERY STRONG/GUSTY WINDS AND A CRITICAL FIRE WEATHER
   RISK WILL EXIST ACROSS SOUTHEAST NM INTO SOUTHWEST TX AND PERHAPS
   PORTIONS OF THE TX SOUTH PLAINS IN THE WAKE OF A DEEPENING SURFACE
   LOW AND ASSOCIATED COLD FRONT. IN THE WEST...HIGH PRESSURE IS
   FORECAST TO WEAKEN ACROSS THE GREAT BASIN...GRADUALLY DIMINISHING
   THE OFFSHORE GRADIENT ACROSS SOUTHERN CA.
   
   ...CRITICAL FIRE WEATHER AREA - SOUTHEAST NM/SOUTHWEST TX...
   
   PRIMARY CONDITIONS: VERY STRONG/GUSTY WINDS AND LOW RH
   
   ASSOCIATED WITH THE POTENT UPPER TROUGH/PRONOUNCED JET STREAK
   CROSSING THE CENTRAL/SOUTHERN PLAINS...VERY STRONG WEST-SOUTHWEST
   WINDS ARE EXPECTED ACROSS A LARGE PART OF SOUTHEAST NM AND SOUTHWEST
   TX/TX SOUTH PLAINS TODAY. STRONG DEEP LAYER WIND FIELDS AND AMPLE
   MIXING SUGGEST SUSTAINED WIND SPEEDS OF 25-40 MPH ARE LIKELY...WITH
   THE POSSIBILITY OF GUSTS TO 50-70 MPH...ESPECIALLY FOR THE
   GUADALUPE/DAVIS MOUNTAINS AND ADJACENT AREAS OF SOUTHEAST NM/FAR
   WEST TX. AS DOWNSLOPE TRAJECTORIES INCREASE IN THE WAKE OF THE
   SURFACE LOW/ASSOCIATED COLD FRONT...A VERY DRY AIRMASS WITH SINGLE
   DIGIT DEWPOINTS WILL FAVOR AFTERNOON MINIMUM RH VALUES OF 15-20
   PERCENT IN THE TRANSPECOS REGION...WITH BOUNDARY LAYER MIXING LIKELY
   UNDERDONE /AND THUS RH VALUES TOO HIGH/ IN NUMERICAL MODEL
   FORECASTS. ALTHOUGH THE PATTERN IS SUGGESTIVE OF SIGNIFICANT WIND
   GUSTS AND A HIGH-END FIRE POTENTIAL TODAY...RELATIVELY COOL
   TEMPERATURES /MAINLY IN THE 50S/ WILL PRECLUDE THE ISSUANCE OF AN
   EXTREMELY CRITICAL RISK.
   
   ...SOUTHERN CA...
   LOCALLY STRONG/GUSTY NORTH-NORTHEAST WINDS ARE ONGOING ACROSS THE
   COASTAL RANGE/ADJACENT VALLEY AREAS OF SOUTHERN CA THIS MORNING.
   WHILE THE GUSTY WINDS WILL PERSIST INTO THE AFTERNOON...THE OFFSHORE
   GRADIENT IS FORECAST TO GRADUALLY WEAKEN THROUGH THE DAY...WITH
   UPPER SUPPORT/LARGE SCALE SUBSIDENCE DIMINISHING AS WELL. A LIMITED
   DURATION OF THE OFFSHORE EVENT AND MARGINAL NATURE OF
   TEMPERATURES/RH VALUES SUGGEST CRITICAL CONDITIONS ARE NOT LIKELY.
