   VALID 131200Z - 141200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR SE WY/WRN NEB/ERN CO/WRN KS/NE
   NM/OK AND TX PANHANDLES...
   
   ...SYNOPSIS...
   LARGE RIDGE ALOFT WILL REMAIN CENTERED ACROSS THE SRN PLAINS...WITH
   SEVERAL IMPULSES MOVING EWD ACROSS THE NRN STATES. MID LEVEL SPEED
   MAX OF 60-70 KT WILL EXTEND FROM SRN MN THROUGH WY BY LATE AFTN.
   TEMPERATURES WILL BE MUCH ABOVE NORMAL /15-20 DEGREES/ ACROSS THE
   PLAINS...WITH MORE RECORD HIGH TEMPS LIKELY. CRITICAL FIRE WEATHER
   CONDITIONS ARE POSSIBLE ACROSS PORTIONS OF THE HIGH PLAINS WHERE HOT
   AND WINDY CONDITIONS WILL DEVELOP IN CONJUNCTION WITH LOW RH VALUES.
   
   ...CRITICAL FIRE WEATHER AREA 1 - SE WY/WRN NEB/ERN CO/WRN KS/NE
   NM/OK AND TX PANHANDLES...
   
   PRIMARY CONDITIONS: SUSTAINED WINDS 15-20 MPH WITH HIGHER
   GUSTS/MINIMUM RH VALUES BELOW 15 PERCENT/ABOVE NORMAL TO RECORD HIGH
   TEMPS/LONG TERM DROUGHT
   
   TEMPS WILL CONTINUE TO BE MUCH ABOVE NORMAL...WITH RECORD HIGHS
   POSSIBLE IN SOME LOCATIONS. FORECAST SOUNDINGS SUGGEST SFC DEWPOINTS
   WILL BE IN THE TEENS ACROSS SE WY/ERN CO/WRN NEB WHICH WILL ALLOW
   MINIMUM RH VALUES TO FALL BELOW 15 PERCENT. STEEP LAPSE RATES ON THE
   ORDER OF 9 C/KM WILL ALLOW THE BOUNDARY LAYER TO BE MIXED TO NEARLY
   500MB ACROSS PORTIONS OF THE HIGH PLAINS. HIGHER MOMENTUM AIR WILL
   BE MIXED TO LOWER LEVELS WITH STRONG WIND GUSTS DEVELOPING BY AFTN.
   
   LATEST 10 HR FUEL OBSERVATIONS ARE LESS THAN 5 PERCENT ACROSS THE
   CRITICAL AREA. WIND CRITERIA MAY NOT BE MET ACROSS ALL OF THE
   AREA...BUT THE COMBINATION OF VERY DRY AND WARM CONDITIONS WILL
   INCREASE THE POTENTIAL FOR WIND DRIVEN FIRES.
   
   ...SRN PLAINS...
   ABOVE NORMAL TO RECORD HIGH TEMPS ARE EXPECTED TODAY WITH LOW
   HUMIDITY. MINIMUM RH VALUES WILL RANGE FROM BELOW 10 PERCENT WEST OF
   THE DRYLINE TO 20-30 PERCENT ACROSS ERN OK/NCNTRL TX. THERE WILL
   CONTINUE TO BE A THREAT OF WILDFIRE GIVEN THE DRY FUELS AND
   FAVORABLE FIRE WEATHER CONDITIONS. THE RIDGE ALOFT WILL TEND TO
   DISCOURAGE STRONG SYNOPTIC SCALE WINDS.

   VALID 141200Z - 151200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR AZ/NM...
   
   ...SYNOPSIS...
   VIGOROUS UPPER LEVEL TROUGH NOW OFF WEST COAST IS FORECAST TO MOVE
   INLAND ACROSS CA AND THE GREAT BASIN ON FRIDAY. WINDS ALOFT WILL
   INCREASE TO 80-90 KT ACROSS SRN CA/AZ BY AFTN. ASSOCIATED SFC TROUGH
   WILL DEEPEN OVER SRN GREAT BASIN IN RESPONSE TO LARGE SCALE HEIGHT
   FALLS...WHILE LEE TROUGH DEVELOPS OVER THE PLAINS. INCREASING
   PRESSURE GRADIENT WILL INDUCE STRONGER WINDS ACROSS THE PLAINS ON
   FRIDAY.
   
   ...CRITICAL FIRE WEATHER AREA 1 - AZ/NM...
   
   PRIMARY CONDITIONS: VERY STRONG WINDS OF 20-35 MPH/ LOW RH VALUES /
   LONG TERM DROUGHT
   
   SUSTAINED WINDS OF 20-35 MPH WILL DEVELOP ON FRIDAY AHEAD OF A VERY
   STRONG UPPER LEVEL STORM SYSTEM. MINIMUM RH VALUES WILL FALL BELOW
   15 PERCENT ESPECIALLY ACROSS THE LOWER ELEVATIONS AND DESERTS WHERE
   TEMPS WILL BE IN THE 80S/90S. THE COMBINATION OF STRONG WINDS ALOFT
   AND TIGHT PRESSURE GRADIENT WILL RESULT IN HIGHER SFC WIND GUSTS
   BETWEEN 40-50 MPH. RECENT FIRE DANGER OBSERVATIONS RANGE FROM HIGH
   TO EXTREME.
   
   ...SRN PLAINS...
   TEMPS IN THE 90S COMBINED WITH LOW RH VALUES WILL CONTRIBUTE TO AN
   INCREASING FIRE WEATHER THREAT WHICH WILL BE EVEN MORE ENHANCED ON
   SATURDAY. MINIMUM RH VALUES WILL GENERALLY BE LESS THAN 20-25
   PERCENT EVEN WITH SFC DEWPOINTS IN THE 40S/50S.
