   VALID 271200Z - 281200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE SRN ROCKIES
   REGION...
   
   ...SYNOPSIS...
   AN UPPER LOW WILL MOVE EWD FROM OFF THE NRN BAJA CA COAST INTO THE
   SRN ROCKIES THROUGH TONIGHT. AHEAD OF THIS SYSTEM...MODERATE WINDS
   AND LOW RH READINGS WILL LEAD TO CRITICAL FIRE WEATHER CONDITIONS
   OVER PORTIONS OF THE FAR SRN ROCKIES THIS AFTERNOON. EAST OF A
   DRYLINE OVER CENTRAL NM SCT TSTMS WILL BRING MUCH NEEDED RAINFALL TO
   THE SRN HIGH PLAINS REGION. ELSEWHERE ACROSS THE NATION...SFC HIGH
   PRESSURE WILL BE THE DOMINANT SFC FEATURE PROVIDING FOR LIGHT WINDS.
   LOW RH READINGS WILL BE PREVALENT IN ASSOCIATION WITH THE SFC HIGH
   OVER MUCH OF THE UPPER MIDWEST/GREAT LAKES REGION LEADING TO HIUGH
   FIRE DANGER. TWO EXCEPTIONS TO THE GENERALLY LIGHT WINDS WILL OCCUR
   TODAY. ONE OVER THE NRN HIGH PLAINS WHERE MODERATE SFC WINDS WILL
   OCCUR IN ASSOCIATION WITH A NRN STREAM UPPER TROUGH MOVING SEWD OUT
   OF CANADA. THE OTHER EXCEPTION WILL BE OVER FL WHERE MODERATE WLY
   WINDS OCCUR IN THE WAKE OF COLD FRONT.
   
   ...CRITICAL FIRE WEATHER AREA 1 - FAR SERN AZ/SWRN NM AND FAR WRN
   TX...
   
   PRIMARY CONDITIONS: SUSTAINED SWLY WINDS FROM 20-30 MPH...MIN RH
   READINGS AROUND 15 PERCENT...ISOLATED DRY TSTMS AND LONG TERM
   DROUGHT.
   
   AHEAD OF A STRONG UPPER SYSTEM...WSWLY MID LEVEL FLOW WILL
   STRENGTHEN OVER THE DESERT SW/SRN ROCKIES. IN THE WAKE OF AN
   ASSOCIATED SFC COLD FRONT...A MODERATE PRESSURE GRADIENT COMBINED
   WITH COLD ADVECTION/STEEP LOW-MID LEVEL LAPSE RATES WILL SUPPORT
   MODERATE SWLY SFC WINDS FROM 20-30 MPH WITH GUSTS UP TO 40 MPH IN
   THE HIGHER TERRAIN. ALTHOUGH TEMPERATURES WILL BE MUCH COOLER THAN
   RECENT DAYS...LOW DWPTS WILL SUPPORT MIN RH READINGS AROUND 15
   PERCENT.  MID LEVEL MOISTURE AHEAD OF THE UPPER SYSTEM WILL SUPPORT
   ISOLATED TSTMS OVER PORTIONS OF ERN AZ/WRN NM. RELATIVELY HIGH CLOUD
   BASES WILL AID IN LITTLE PRECIP REACHING THE GROUND.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0400 AM CDT THU APR 27 2006
   
   VALID 281200Z - 291200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SRN NM/WRN TX...
   
   ...SYNOPSIS...
   A SRN STREAM UPPER LOW OVER THE SRN ROCKIES WILL MOVE EWD INTO THE
   SRN PLAINS WHILE GRADUALLY PHASING WITH A NRN STREAM TROUGH MOVING
   SEWD FROM THE NRN PLAINS. IN ASSOCIATION WITH THIS UPPER SYSTEM...A
   SFC LOW/DRYLINE WILL MOVE EWD ACROSS WRN TX DURING THE DAY. AREAS TO
   THE WEST OF THE DRYLINE AND SOUTH OF A COLD FRONT WILL SEE CRITICAL
   FIRE WEATHER CONDITIONS. ELSEWHERE ACROSS THE NATION...SFC HIGH
   PRESSURE WILL BE THE DOMINANT SENSIBLE WEATHER FEATURE. ALTHOUGH LOW
   DWPTS/RH READINGS WILL ACCOMPANY THE HIGH OVER MUCH OF THE ERN
   STATES...GENERALLY LIGHT WINDS WILL LIMIT THE POTENTIAL FOR CRITICAL
   FIRE WEATHER CONDITIONS.
   
   ...CRITICAL FIRE WEATHER AREA 1 - FAR SERN NM/SWRN TX...
   
   PRIMARY CONDITIONS: SUSTAINED WLY WINDS FROM 20-30 MPH WITH GUSTS UP
   TO 40 MPH...MIN RH READINGS AROUND 15 PERCENT...LONG TERM DROUGHT
   
   STEEP LAPSE RATES IN THE LOW-MID LEVELS IN THE WAKE OF A PACIFIC
   COLD FRONT/DRYLINE WILL OCCUR OVER THE HIGHER TERRAIN OF SWRN
   TX/SERN NM ON DAY TWO. STRONG WIND FIELDS WILL THUS MIX TOWARDS THE
   SURFACE AND AID IN MODERATE SFC WINDS. ALTHOUGH TEMPERATURES WILL BE
   COOLER THAN RECENTLY...LOW DWPTS WILL STILL SUPPORT MIN RH READINGS
   AROUND 15 PERCENT. AS ANOTHER STRONGER COLD FRONT MOVES SWD INTO THE
   AREA OVERNIGHT...RH READINGS WILL RISE DRAMATICALLY.
   
   ...FLA...
   SFC WINDS WILL TURN NELY AS SFC PRESSURES FALL OVER THE LOWER MS
   VALLEY IN RESPONSE TO APPROACHING UPPER SYSTEM OVER THE PLAINS. AS
   DRY AIR REMAINS OVER THE REGION AND TEMPERATURES WARM OVER DAY
   ONE...MIN RH READINGS WILL REACH CRITICAL LEVELS /25-35 PERCENT/
   DURING THE AFTERNOON. SUSTAINED WINDS SHOULD GENERALLY REMAIN LESS
   THAN 15 MPH PRECLUDING AN OUTLOOK AREA.
