   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0146 AM CDT SAT AUG 09 2008
   
   VALID 091200Z - 101200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER LOW OFFSHORE OF THE BRITISH COLUMBIA/WASHINGTON COASTS WILL
   BEGIN TO SHIFT ONSHORE TODAY...OVERSPREADING STRONGER SWLY WINDS
   ALOFT ACROSS MUCH OF THE PACIFIC NORTHWEST. MONSOONAL MOISTURE...AS
   EVIDENCED BY PWAT VALUES NEAR .75-1.00 INCH ON 00Z SOUNDING
   DATA...WILL CONTINUE TO BE SUPPORTIVE OF WET THUNDERSTORM
   DEVELOPMENT ACROSS A WIDESPREAD AREA IN AN UNSTABLE
   ATMOSPHERE...ESPECIALLY BY LATE AFTERNOON. THE MOST SIGNIFICANT
   STORMS ARE EXPECTED ACROSS ERN ID AND WRN MT. 
   
   AT THE SURFACE...A COLD FRONT WILL PUSH INTO MT BY THE END OF THE
   PERIOD...AND LOCALLY GUSTY WINDS WILL AFFECT MUCH OF ERN WA/OR AND
   NRN CA/NWRN NV/WRN ID. ALTHOUGH STRONGER GUSTS ARE
   LIKELY...SUSTAINED WINDS ARE EXPECTED TO REMAIN BELOW CRITICAL
   THRESHOLDS. 
   
   MEANWHILE IN THE EAST...AN UPPER TROUGH OF LOW PRESSURE WILL BE
   DOMINANT. THE COLD FRONT THAT BROUGHT WIDESPREAD THUNDERSTORMS TO
   THE SOUTHEAST YESTERDAY WILL CONTINUE TO SAG SWD INTO SRN FL. DRIER
   AIR WILL BUILD IN BEHIND...WITH CRITICALLY LOW RHS MAINLY CONFINED
   TO THE FL PANHANDLE.
   
   ...CA...SERN OR...SRN ID...NV...
   MARGINALLY CRITICAL FIRE CONDITIONS ARE EXPECTED ACROSS A WIDESPREAD
   AREA FOLLOWING A COLD FRONTAL PASSAGE AND IN ASSOCIATION WITH AN
   UPPER TROUGH MOVING ONSHORE. LOCALLY GUSTY SWLY WINDS WILL BE LIKELY
   ESPECIALLY BY AFTERNOON WHEN DEEP MIXING ALLOWS THE STRONGER WINDS
   ALOFT TO REACH THE SURFACE. SUSTAINED SPEEDS ARE GENERALLY EXPECTED
   TO REMAIN BELOW CRITICAL THRESHOLDS...ALTHOUGH HIGHER ELEVATIONS
   WILL EXPERIENCE STRONGER SPEEDS. RELATIVE HUMIDITIES WILL LOWER TO
   10 TO 15 PERCENT...ENHANCING FIRE DANGER IN GUSTY WINDS.
   
   ...FL PANHANDLE/SRN GA/SRN AL...
   EARLY MORNING WV IMAGERY SHOWS MUCH DRIER AIR/SUBSIDENCE BUILDING IN
   BEHIND A COLD FRONT THAT IS POSITIONED ROUGHLY ACROSS THE CNTRL FL
   PENINSULA. AFTERNOON RELATIVE HUMIDITIES MAY BRIEFLY DROP TO NEAR 25
   PERCENT ACROSS SRN GA/SRN AL...AND 35 PERCENT ACROSS THE FL
   PANHANDLE AWAY FROM THE IMMEDIATE COAST. LIGHT NWLY WINDS WILL LIMIT
   CRITICAL DESIGNATION.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0314 AM CDT SAT AUG 09 2008
   
   VALID 101200Z - 111200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   THE UPPER LOW THAT REMAINS OFFSHORE OF BRITISH COLUMBIA/WASHINGTON
   THIS MORNING WILL PROGRESS NEWD INTO SERN BRITISH COLUMBIA. HOT AND
   DRY CONDITIONS WILL CONTINUE ACROSS MUCH OF THE WRN STATES AS UPPER
   RIDGING SLOWLY BUILDS IN BEHIND. GIVEN TRAJECTORY OF THE UPPER
   LOW...THE STRONGEST WINDS WILL REMAIN CLOSE TO THE U.S./CANADIAN
   BORDER...WHERE ABOVE NORMAL MOISTURE AND MARGINAL RELATIVE
   HUMIDITIES WILL EXIST. FARTHER W...RELATIVE HUMIDITIES WILL DROP
   INTO THE TEENS...ALTHOUGH SUSTAINED WINDS WILL REMAIN BELOW CRITICAL
   THRESHOLDS. HOWEVER...LOCALLY GUSTY WINDS MAY BE POSSIBLE ACROSS ERN
   OR/WA...NRN CA/NV/UT...AND ID. MEANWHILE AT THE SURFACE...THE COLD
   FRONTAL PROGRESSION WILL BE SOMEWHAT SLOW...ALTHOUGH A WIND SHIFT
   WILL OCCUR IN MT/WY...WITH GUSTY WINDS FOLLOWING THE FRONTAL
   PASSAGE.  
   
   IN THE FOUR CORNERS REGION AND ERN GREAT BASIN...WET THUNDERSTORMS
   WILL CONTINUE TO AFFECT A WIDESPREAD AREA IN THE AFTERNOON.
   
   ...PORTIONS OF THE NORTHWEST...
   AS PREVIOUSLY MENTIONED...STRONGER WINDS WILL MAINLY BE CONFINED
   NEAR THE U.S./CANADIAN BORDER. WV IMAGERY SEEMS TO SUPPORT THAT THE
   DRIEST AIR WOULD MOVE INTO PORTIONS OF THE SOUTHWEST...AWAY FROM
   STRONGER WINDS. HOWEVER...THERE MAY BE POTENTIAL FOR SOMEWHAT DRIER
   AIR TO MOVE INTO ERN ID/WRN MT...WHERE WINDS MAY BE STRONGER IN A
   POST COLD FRONTAL REGIME...AND AS STRONGER WINDS IN ASSOCIATION WITH
   THE UPPER LOW REACH THE SURFACE AS DEEP MIXING OCCURS IN THE
   AFTERNOON. GIVEN UNCERTAINTY IN THIS SCENARIO AS MODEL FORECASTS
   SEEM SOMEWHAT MARGINAL...WILL WAIT TO OUTLINE A CRITICAL AREA AT
   THIS TIME.
