   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0257 AM CDT FRI APR 04 2008
   
   VALID 041200Z - 051200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A MID/UPPER-LEVEL SHORT WAVE TROUGH WILL TRACK FROM THE SRN ROCKIES 
   TO THE LOWER MS RIVER VALLEY THROUGH EARLY SAT. A SURFACE COLD FRONT
   ACROSS NRN TX WILL PUSH SWD REACHING THE WRN GULF COAST BY THIS
   AFTERNOON.
   
   ...LOWER RIO GRANDE VALLEY OF DEEP S TX...
   SIGNIFICANT UNCERTAINTY EXISTS WITH REGARDS TO THE DEGREE OF DRYING
   AFTER A COLD FRONT PASSAGE LATER THIS MORNING. DESPITE SURFACE DEW
   POINTS IN THE SINGLE DIGITS ACROSS FAR WRN TX ATTM...THE PENETRATION
   OF VERY DRY AIR INTO DEEP S TX APPEARS PROBLEMATIC. THE MODIFIED AIR
   MASS BEHIND THE COLD FRONT HAS SUPPORTED AN INCREASE IN SURFACE DEW
   POINTS INTO THE 30S/40S ACROSS NWRN TX. LATEST MODEL GUIDANCE DEPICT
   A SUBTLE INCREASE IN NLY VERSUS NWLY COMPONENT TO LOW-LEVEL
   FLOW...WHICH WILL HAVE A LARGE IMPACT ON PLACEMENT OF THE OVERLYING
   MOISTURE GRADIENT. IT APPEARS THAT ANY DURATION OF CRITICALLY LOW RH
   SHOULD REMAIN RELATIVELY SHORT. WITH SUSTAINED SURFACE WINDS AROUND
   20 MPH...A LOCALIZED/BRIEF CRITICAL THREAT IS ANTICIPATED.

   VALID 051200Z - 061200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE CNTRL/SRN HIGH
   PLAINS AND SRN ROCKIES...
   
   ...SYNOPSIS...
   POTENT MID/UPPER-LEVEL SHORT WAVE TROUGH...JUST OFF THE PACIFIC NW
   COAST ATTM...WILL EJECT ACROSS THE NRN ROCKIES ONTO THE NRN PLAINS
   THROUGH EARLY SUN. THIS FEATURE WILL AID IN LEE CYCLOGENESIS ALONG
   THE CO/KS BORDER. S OF THE CYCLONE...LOW-LEVEL SWLYS WILL STRENGTHEN
   WITH THE SURFACE DRY LINE MIXING INTO SWRN KS AND WRN OK/TX ON SAT
   AFTERNOON.
   
   ...CRITICAL FIRE WEATHER AREA - PORTIONS OF THE CNTRL/SRN HIGH
   PLAINS AND SRN ROCKIES...
   
   PRIMARY CONDITIONS: STRONG WINDS / LOW RH / LONG-TERM DRYNESS
   
   CRITICAL CONDITIONS ARE EXPECTED OVER A BROAD AREA AS LOW-LEVEL
   SWLYS INCREASE SPREADING A DRY AIR MASS FROM THE SOUTHWEST NEWD INTO
   THE HIGH PLAINS. SUSTAINED SURFACE WINDS OF 20 TO 25 MPH WILL BE
   COMMON...ALONG WITH RH VALUES DROPPING TO AROUND 8 TO 15 PERCENT.
   THE MOST SIGNIFICANT FIRE WEATHER THREAT SHOULD EVOLVE FROM E-CNTRL
   NM/WRN TX PANHANDLE NEWD TO THE CO/KS/OK BORDER REGION. HERE...VERY
   DEEPLY MIXED THERMODYNAMIC PROFILES SHOULD DEVELOP WITHIN A
   FAVORABLE DOWNSLOPE FLOW REGIME. THIS WILL SUPPORT SUSTAINED SURFACE
   WINDS AROUND 25 TO 30 MPH. AS TEMPERATURES WARM WELL INTO THE
   70S...RH VALUES SHOULD PLUMMET TO BETWEEN 6 TO 10 PERCENT.
