   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0332 AM CDT FRI MAY 09 2008
   
   VALID 091200Z - 101200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR NRN AND ERN AZ / FAR SERN UT /
   MOST OF NM / FAR WRN TX...
   
   ...SYNOPSIS...
   AN UPPER-LEVEL TROUGH WILL DIG FROM THE PACIFIC NW/NRN GREAT
   BASIN...REACHING THE NRN PLAINS TO THE CNTRL ROCKIES BY EARLY SAT. A
   LOW AMPLITUDE SRN STREAM IMPULSE OFF THE BAJA CA COAST WILL EJECT
   NEWD TOWARDS THE SRN ROCKIES/HIGH PLAINS. AT THE SURFACE...LOW
   PRESSURE WILL BECOME CENTERED OVER SERN CO THIS AFTERNOON...WHILE A
   COLD FRONT SETTLES SWD INTO THE CNTRL/SRN GREAT BASIN.
   
   ...CRITICAL FIRE WEATHER AREA - NRN AND ERN AZ / FAR SERN UT / MOST
   OF NM / FAR WRN TX...
   
   PRIMARY CONDITIONS: STRONG WINDS / LOW RH / LONG-TERM DRYNESS
   
   A BROAD SWATH OF MODERATELY STRONG MID-LEVEL W/SWLYS WILL OVERSPREAD
   MUCH OF THE SRN ROCKIES AND SRN GREAT BASIN. THIS WOULD TYPICALLY
   RESULT IN A WIDESPREAD CRITICAL THREAT GIVEN LOW RH ACROSS THE
   REGION. HOWEVER...A SRN STREAM IMPULSE AND ASSOCIATED
   MID/UPPER-LEVEL CLOUD COVERAGE WILL HINDER INSOLATION AND LIKEWISE
   VERTICAL MIXING...MAINLY INVOF SRN ROCKIES. MODEL GUIDANCE DIFFER
   WITH THE OVERALL IMPACT ON SURFACE WINDS AND POTENTIAL INCREASE IN
   RH. NEVERTHELESS...CONSENSUS OF GUIDANCE SUGGEST AREAS OF SUSTAINED
   SURFACE WINDS SHOULD REACH 20 TO 25 MPH AROUND PEAK HEATING WITH RH
   VALUES FALLING TO BETWEEN 8 TO 15 PERCENT.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0437 AM CDT FRI MAY 09 2008
   
   VALID 101200Z - 111200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR SWRN TX / CNTRL NM...
   
   ...SYNOPSIS...
   NRN PLAINS/CNTRL ROCKIES UPPER-LEVEL TROUGH WILL AMPLIFY AS IT
   PROGRESSES EWD TOWARDS THE MS RIVER VALLEY. ATTENDANT SURFACE
   CYCLONE WILL TRACK FROM THE OK/TX PANHANDLES TO THE MID MS RIVER
   VALLEY...INTENSIFYING RAPIDLY LATE IN THE PERIOD AS NRN AND SRN
   STREAM UPPER JETS PHASE. AT THE SURFACE...DRYLINE ATTENDANT TO THE
   LOW WILL REACH THE I-35 CORRIDOR IN CNTRL TX SAT AFTERNOON...WHILE A
   COLD FRONT SWEEPS SWD THROUGH THE SRN PLAINS LATER SAT INTO EARLY
   SUN.
   
   ...CRITICAL FIRE WEATHER AREA - SWRN TX / CNTRL NM...
   
   PRIMARY CONDITIONS: LONG DURATION OF LOW RH / GUSTY WINDS / DROUGHT
   
   STRONG WLY LOW/MID-LEVEL FLOW SHOULD BE ONGOING SAT MORNING AS AN
   UPPER-LEVEL TROUGH PASSES THROUGH THE REGION. ALTHOUGH THESE WINDS
   WILL SUBSIDE THROUGH THE DAY...GUSTY SURFACE WINDS ARE EXPECTED TO
   COMMENCE BY MID-MORNING AS NOCTURNAL INVERSION BREAKS. SUSTAINED
   SPEEDS AROUND 15 TO 25 MPH ARE LIKELY INTO LATE AFTERNOON. THE WLY
   DOWNSLOPE FLOW AND SUBSIDENCE IN THE WAKE OF TROUGH PASSAGE WILL
   ENHANCE WARMING/DRYING ACROSS SWRN TX. HERE...TEMPERATURES SHOULD
   SOAR INTO THE 90S TO AROUND 100. THIS WILL RESULT IN MIN RH VALUES
   NEAR 5 PERCENT AND A LONG DURATION OF CRITICALLY LOW RH. THE PASSAGE
   OF A COLD FRONT SAT NIGHT/EARLY SUN WILL LEAD TO A WIND SHIFT TO THE
   N/NE AND MUCH IMPROVED RH RECOVERY.
