   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN ACTIVE AND PROGRESSIVE UPPER LEVEL PATTERN EMBEDDED WITHIN THE
   SRN BRANCH OF THE WESTERLIES RESIDES OVER THE CONUS.  A STRONG UPPER
   LEVEL TROUGH OVER THE ERN PACIFIC EARLY THIS MORNING WILL MOVE
   ONSHORE TODAY...WHILE ANOTHER UPPER TROUGH OVER THE CNTRL U.S.
   REACHES THE WRN ATLANTIC BY THE END OF THE PERIOD. BETWEEN THE
   TROUGHS...AN UPPER RIDGE WILL MOVE FROM THE INTERMOUNTAIN WEST TO
   THE MISSISSIPPI VALLEY REGION.  THE SURFACE PATTERN IS CHARACTERIZED
   BY A BROAD AREA OF HIGH PRESSURE OVER THE ERN CONUS...AND GENERALLY
   LOWER PRESSURE WITH RAIN AND MOUNTAIN SNOW COVERING A LARGE PORTION
   OF THE WEST. AS THE WRN TROUGH APPROACHES THE CA COAST THIS
   AFTERNOON...INCREASING WLY/SWLY FLOW ALOFT WILL PRODUCE LOCALLY
   BREEZY CONDITIONS IN AZ/NM.  RAIN AND SNOW SHOWERS WILL ACCOMPANY
   THE ERN TROUGH FROM THE MID MISSISSIPPI RIVER VALLEY TO THE MID
   ATLANTIC REGION...OTHERWISE THE EAST IS GENERALLY DRY.
   
   ...SRN AZ/SRN NM...
   A DRY AND MILD AIRMASS IS LOCATED OVER THE SWRN U.S. WITH AFTERNOON
   RH EXPECTED AROUND 15 PERCENT AND TEMPERATURES FROM THE MID 60S TO
   LOWER 70S.  BRIEF/LOCALIZED WIND GUSTS OVER 20 MPH ARE POSSIBLE AS
   THE MID LEVEL WESTERLIES INCREASE AHEAD OF THE NEXT PACIFIC TROUGH.
   
   ...NRN FL...
   A MARGINALLY DRY AIRMASS REMAINS OVER THE SERN U.S. AND RH OVER NRN
   FL MAY BRIEFLY DIP BELOW 40 PERCENT THIS AFTERNOON.  THE LIGHT WINDS
   BELOW 10 MPH AND THE SHORT DURATION OF LOW RH SUGGEST ONLY MARGINAL
   FIRE WEATHER CONDITIONS SHOULD OCCUR.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0401 AM CST SUN FEB 24 2008
   
   VALID 251200Z - 261200Z
   
   ...EXTREMELY CRITICAL FIRE WEATHER AREA FOR SOUTHWEST TX...
   ...CRITICAL FIRE WEATHER AREA FOR WRN TX AND SERN NM...
   
   ...SYNOPSIS...
   THE AMPLITUDE OF THE LARGE SCALE PATTERN INCREASES ON MONDAY...AS AN
   UPPER RIDGE BUILDS NWD ALONG THE PACIFIC COAST AND A TROUGH DIGS SWD
   THROUGH THE CNTRL CONUS.  AS THIS TROUGH DIGS SWD...VERY STRONG
   WESTERLIES EXTEND TO THE U.S./MEXICO BORDER.  THE COMBINATION OF
   VERY HIGH WINDS AND VERY LOW RH WILL RESULT IN EXTREMELY CRITICAL
   FIRE WEATHER CONDITIONS OVER PORTIONS OF WRN TX...EMBEDDED WITHIN A
   LARGER AREA OF CRITICAL FIRE WEATHER CONDITIONS COVERING MUCH OF WRN
   TX AND SERN NM.  ELSEWHERE AROUND THE COUNTY...SURFACE LOW PRESSURE
   DEEPENS OVER THE CNTRL PLAINS AND REACHES THE OHIO VALLEY BY LATE IN
   THE PERIOD.  A COLD FRONT EXTENDING SWWD FROM THE SURFACE LOW WILL
   SWEEP ACROSS THE CNTRL CONUS...BRINGING MUCH COLDER TEMPERATURES AND
   GUSTY NORTH WINDS TO THE NRN/CNTRL PLAINS.  A RESIDUAL DRY AIRMASS
   LINGERING ACROSS THE DEEP SOUTH AND FL WILL PRODUCE A PERIOD OF
   MODERATELY LOW RH DURING THE AFTERNOON.
   
   ...EXTREMELY CRITICAL FIRE WEATHER AREA - SWRN TX...
   
   PRIMARY CONDITIONS: EXTREMELY LOW RH...VERY STRONG/GUSTY WLY WINDS
   SHIFTING TO NWLY AS COLD FRONT PASSES
   
   EXTREMELY CRITICAL FIRE WEATHER CONDITIONS DEVELOP ACROSS A LARGE
   PORTION OF SWRN TX MONDAY.  AS THE UPPER TROUGH DIGS SWD INTO THE
   SCNTRL CONUS...WINDS ASSOCIATED WITH A MID LEVEL JET MAX INCREASE TO
   MORE THAN 60 KTS AT 700 MB /AND 100 KTS AT 500 MB/ FROM FAR WRN TX
   TO CNTRL OK.  STRONG SUBSIDING SWLY FLOW WILL RESULT IN VERY LOW
   SURFACE DEWPOINTS IN THE LOWER TEENS...RH APPROACHING 5 PERCENT...
   AND SUSTAINED WINDS OF 20 TO 30 MPH GUSTING TO 40 MPH.  THE POSITION
   OF THE MID LEVEL JET HELPED TO DEFINE THE ERN/SRN EXTENT OF THE
   EXTREMELY CRITICAL AREA...WHILE THE NRN EDGE IS ALIGNED WITH THE
   EXPECTED LOCATION OF THE COLD FRONT DURING THE EARLY TO MID
   AFTERNOON.  EXTREME CONDITIONS SHOULD PEAK JUST AHEAD OF THE COLD
   FRONT...AS TEMPERATURES CLIMB INTO THE UPPER 70S TO MID 80S
   ACCOMPANIED BY VERY STRONG SWLY/WLY WINDS.  CRITICAL CONDITIONS WILL
   CONTINUE FOLLOWING FRONTAL PASSAGE...WITH WINDS TURNING NWLY AT 20
   TO 30 MPH /AND HIGHER GUSTS/ AND THE RH ONLY RECOVERING TO ABOUT 10
   TO 15 PERCENT.
   
   ...CRITICAL FIRE WEATHER AREA - SERN NM/WRN TX/FAR SWRN OK...
   
   PRIMARY CONDITIONS: WINDY WITH LOW RH
   
   FIRE WEATHER CONDITIONS OVER A LARGE PORTION OF WRN TX NWD THROUGH
   SERN NM TO EXTREME SWRN OK WILL BECOME CRITICAL ON MONDAY.  AS A
   COLD FRONT MOVES SWD...STRONG WLY WINDS /SUSTAINED 20 TO 30 MPH WITH
   HIGHER GUSTS/ BECOME NWLY.  RH DURING THE AFTERNOON IS EXPECTED
   BETWEEN 10 TO 15 PERCENT...WITH THE ERN EDGE OF THE CRITICAL AREA
   DELINEATED BY THE EXPECTED LOCATED OF THE DRY LINE.  TEMPERATURES
   WILL RANGE FROM THE MID 60S IN THE NRN PORTION OF THE CRITICAL AREA
   TO THE MID 80S FARTHER SOUTH.  IN ADDITION TO THE HIGH WIND AND LOW
   RH...DANGEROUS SHIFTING WINDS WILL ACCOMPANY THE COLD FRONT.
   
   ...TX/OK PANHANDLES/SWRN KS...
   NWLY WINDS AND LOW RH WILL COMBINE TO CREATE NEAR CRITICAL
   CONDITIONS NORTH OF THE AFOREMENTIONED CRITICAL REGION. 
   TEMPERATURES MONDAY AFTERNOON SHOULD BE IN THE 50S TO LOWER 60S...
   AFTERNOON RH AROUND 15 PERCENT...AND NWLY WINDS BETWEEN 15 TO 30
   MPH.
   
   ...NRN/CNTRL FL...
   A DRY AIRMASS SHOULD CONTINUE TO LINGER ACROSS FL ON MONDAY.  AS THE
   AFTERNOON TEMPERATURES CLIMB INTO THE MID 70S...THE MINIMUM RH COULD
   FALL AS LOW AS 35 PERCENT.  BUT LIGHT WLY WINDS AND BORDERLINE RH
   PRECLUDE A CRITICAL AREA.
