   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0158 AM CDT MON JUN 09 2008
   
   VALID 091200Z - 101200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   UPPER LEVEL FLOW REGIME WILL REMAIN QUITE ACTIVE WITH AN UPPER
   DISTURBANCE MOVING NEWD OVER THE GREAT LAKES REGION WITH ANOTHER
   DISTURBANCE MOVING SEWD TOWARDS THE PACIFIC NW.  MEANWHILE AN UPPER
   LEVEL RIDGE WILL WEAKEN BUT IT WILL STILL INFLUENCE THE WEATHER OVER
   THE SE/E COAST OF THE U.S.  IT APPEARS THAT NO LARGE AREAS OF
   CRITICAL FIRE WEATHER CONDITIONS WILL EXIST.
   
   ...PARTS OF NRN FL / GA / SC / NC...
   
   WITH TEMPS WARMING INTO THE 90S/LOW 100S...BRIEF SPELLS OF NEAR
   CRITICAL RH MAY OCCUR IN LOCALIZED AREAS DURING PEAK HEATING AND
   AWAY FROM THUNDERSTORMS.  HOWEVER...WINDS SHOULD GENERALLY REMAIN
   LIGHT AWAY FROM ANY STORMS THAT DO DEVELOP...PRECLUDING A CRITICAL
   AREA.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0348 AM CDT MON JUN 09 2008
   
   VALID 101200Z - 111200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR LARGE PART OF THE SWRN U.S....
   ...CRITICAL FIRE WEATHER AREA FOR CENTRAL VALLEYS OF CA...
   
   ...SYNOPSIS...
   AN UPPER TROUGH WILL STRENGTHEN AND MOVE SEWD INTO THE NWRN CONUS
   REGION DURING THE DAY 2 PERIOD.  WEAK UPPER RIDGING WILL OCCUR
   DOWNSTREAM OF THIS FEATURE...AND AN UPPER TROUGH WILL EXIT OVER THE
   NERN QUARTER OF THE U.S.  AT THE SURFACE...A COLD FRONT IS FORECAST
   TO MOVE SWD OVER THE WEST WITH A SURFACE LOW AND SUBSEQUENT
   STRENGTHENING PRESSURE GRADIENT DEVELOPING ACROSS THE GREAT BASIN.
   
   ...CRITICAL FIRE WEATHER AREA - LARGE PART OF THE SWRN U.S....
   
   PRIMARY CONDITIONS: STRONG WINDS / LOW RH / DROUGHT
   
   LATEST DETERMINISTIC GUIDANCE SUGGESTS STRONG WINDS TO DEVELOP IN
   RESPONSE TO A STRENGTHENING SURFACE PRESSURE GRADIENT ASSOCIATED
   WITH SURFACE CYCLOGENESIS AND STRENGTHENING FLOW FIELDS ALOFT. 
   FORECAST SOUNDINGS SHOW STEEP LAPSE RATES...WHICH WILL ENABLE DEEP
   MIXING AND PROMOTE RH TO LIKELY FALL INTO THE TEENS AND SINGLE
   DIGITS.  ATTM...MODEL CONSENSUS/ENSEMBLES DENOTE RH MEETING CRITICAL
   THRESHOLDS AND PROBABLE SUSTAINED SWLY WINDS IN THE 20-25 MPH RANGE
   WITH HIGHER GUSTS.  REFINEMENTS WHERE CRITICAL CONDITIONS ARE
   FORECAST TO OCCUR MAY BE NEEDED IN LATER OUTLOOKS...ESPECIALLY IN
   THE HIGH PLAINS IF IT BECOMES MORE APPARENT A CRITICAL FIRE WEATHER
   THREAT EXISTS.
   
   ...CRITICAL FIRE WEATHER AREA - CENTRAL VALLEYS OF CA...
   
   PRIMARY CONDITIONS: STRONG WINDS / LOW RH / DROUGHT
   
   LATEST THINKING IS CRITICAL CONDITIONS ARE PROBABLE ACROSS PARTS OF
   THE CENTRAL CA VALLEY REGION.  DETERMINISTIC GUIDANCE DEPICTS
   MODESTLY STRONG NWLY BOUNDARY LAYER WINDS DEVELOPING.  WARM
   AFTERNOON TEMPS WILL STEEPEN LOW LEVEL LAPSE RATES FURTHER...LIKELY
   ENHANCING THE POTENTIAL FOR STRONG SURFACE WINDS.  PER FORECAST
   SOUNDINGS...IT APPEARS N-NWLY WINDS MAY BE SUSTAINED 20-25 MPH WITH
   HIGHER GUSTS...ESPECIALLY IN FAVORED AREAS.  VERY WARM AFTERNOON
   TEMPS /WELL INTO THE 80S AND PERHAPS 90S IN SOME LOCATIONS/ WILL
   FAVOR MIN RH VALUES TO BE IN THE LOWER TEENS AND UPPER SINGLE DIGITS
   ACCORDING TO THE LATEST MODEL ENSEMBLE OUTPUT.
