   VALID 141200Z - 151200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR SRN GREAT BASIN AND LOWER CO RIVER
   VALLEY...
   
   ...SYNOPSIS...
   EARLY MORNING WATER VAPOR LOOPS CLEARLY INDICATE NEXT LARGE SCALE
   TROUGH APPROACHING THE WEST COAST. SYSTEM IS EXPECTED TO DEEPEN OVER
   THE NEXT 24 HOURS...WITH A CLOSED LOW OVER SERN CA BY 12Z SUNDAY.
   SFC RESPONSE WILL BE DEEPENING LOW PRESSURE SYSTEM OVER THE GREAT
   BASIN WITH INCREASING WINDS FROM THE LOWER CO RIVER VALLEY NWD TO
   SRN ID. SFC COLD FRONT WILL LIKELY EXTEND FROM TWF/DRA BY LATE AFTN.
   FARTHER EAST...ANOTHER LARGE SCALE STORM SYSTEM WILL BE AFFECTING
   THE SRN PLAINS...WITH MID LEVEL NLY JET INCREASING TO 60-70 KT FROM
   THE TX PANHANDLE THROUGH THE TRANSPECOS REGION. STRONG POST-FRONTAL
   WINDS AND LOW HUMIDITY WILL CONTRIBUTE TO NEAR CRITICAL FIRE
   CONDITIONS ACROSS PORTIONS OF SRN TX THIS AFTN.
   
   ...CRITICAL FIRE WEATHER AREA - SRN NV/SERN CA/WRN AZ...
   
   PRIMARY CONDITIONS: SUSTAINED S/SWLY WINDS 20-25 MPH/RH VALUES BELOW
   15 PERCENT/LONG TERM DROUGHT
   
   RECENT FIRE DANGER CLASS OBSERVATIONS RANGE FROM VERY HIGH TO
   EXTREME IN THIS AREA. AS DIGGING UPPER SYSTEM APPROACHES FROM THE
   ERN PACIFIC...INCREASING SFC PRESSURE GRADIENT WILL SUPPORT STRONG
   WINDS DEVELOPING BY AFTN. COMBINED WITH MAX TEMPS IN THE 70S/80S AND
   SFC DEWPOINTS IN THE SINGLE DIGITS...MIN RH VALUES WILL RANGE FROM
   AROUND 7-12 PERCENT. THIS WILL INCREASE POTENTIAL FOR WIND DRIVEN
   WILDFIRE SHOULD IGNITIONS OCCUR.
   
   ...SRN/SWRN TX...
   A POST-FRONTAL DRY AIRMASS WILL CONTRIBUTE TO NEAR CRITICAL FIRE
   CONDITIONS TODAY ACROSS PORTIONS OF S TX...INCLUDING THE RIO GRANDE
   PLAINS. MAX TEMPS ARE FORECAST TO CLIMB INTO THE 70S...WITH
   DEWPOINTS ONLY IN THE MID 30S TO LOWER 40S...RESULTING IN LOW
   HUMIDITY VALUES BELOW 25 PERCENT.

   VALID 151200Z - 161200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   IN THE WEST...CLOSED UPPER LOW WILL DIG ACROSS THE LOWER CO RIVER
   VALLEY...WITH THE MID LEVEL JET MAX FORECAST TO BE WELL SOUTH OF THE
   LOW ACROSS BAJA ON SUNDAY AFTN. SHORT TERM MODEL SOLUTIONS DIFFER ON
   THE INTENSITY OF THIS SYSTEM...WITH THE GFS SUGGESTING A LESS
   AMPLIFIED STORM SYSTEM. IN EITHER CASE...SFC LOW WILL DEEPEN INVOF
   THE FOUR CORNERS WITH INCREASING SLY WINDS OF 20-35 MPH WITH HIGHER
   GUSTS. MAX TEMPS WILL BE A BIT COOLER THAN NORMAL ACROSS NRN AND
   CNTRL AZ...AND THIS WILL TEMPER THE THREAT FOR CRITICAL FIRE
   CONDITIONS. IN THE LOWER ELEVATIONS OF SE AZ/SRN NM AND FAR W
   TX...NORMAL TO SLIGHTLY ABOVE NORMAL TEMPS ARE FORECAST...WHICH WILL
   HEIGHTEN FIRE CONCERNS ON SUNDAY.
   
   ...LOWER ELEVATIONS OF SERN AZ/SRN NM...
   WINDY CONDITIONS WILL DEVELOP ONCE AGAIN ON SUNDAY IN RESPONSE TO
   DIGGING UPPER SYSTEM. SUSTAINED SFC WINDS OF 25-35 MPH ARE LIKELY
   ACROSS SRN AZ AND SRN NM. MIN HUMIDITY VALUES WILL BE LOWEST IN THE
   LOWER ELEVATIONS...WHERE HIGH TEMPS ARE EXPECTED TO RISE INTO THE
   LOW/MID 80S WITH MIN RH VALUES AROUND 10-15 PERCENT. FARTHER EAST
   ACROSS SERN NM AND FAR W TX...WARM AND DRY CONDITIONS ARE FORECAST
   THOUGH SFC WINDS WILL NOT BE AS STRONG.
