   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0329 AM CDT TUE OCT 10 2006
   
   VALID 101200Z - 111200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR SWRN ORE...NRN CA...
   
   ...SYNOPSIS...
   CLOSED UPPER-LEVEL LOW OVER NRN NV WILL SHIFT SLOWLY W/SW OFF THE
   NRN CA COAST BY WEDNESDAY MORNING. A MID-LEVEL SPEED MAX AND
   ASSOCIATED SUBSIDENCE REGION TO THE NW OF THE LOW WILL GRADUALLY
   SHIFT OFFSHORE FROM SRN ORE/NRN CA. SURFACE HIGH PRESSURE WILL
   WEAKEN ACROSS THE NRN ROCKIES/NRN PLAINS AS A STRONG COLD FRONT
   APPROACHES FROM THE CANADIAN PRAIRIES. THIS FRONT WILL BE IN
   ASSOCIATION WITH AN INTENSIFYING UPPER-LEVEL TROUGH DIGGING INTO THE
   UPPER MIDWEST.
   
   ...CRITICAL FIRE WEATHER AREA - SWRN ORE...NRN CA...
   
   PRIMARY CONDITIONS: GUSTY WINDS / ONGOING LOW RH
   
   GUSTY NELY OFFSHORE WINDS EARLY THIS MORNING HAVE LED TO RH VALUES
   BELOW 30 PERCENT IN MANY LOCATIONS W OF THE CASCADES/NRN SIERRAS IN
   SWRN ORE AND NRN CA. AS DAYTIME HEATING COMMENCES AND TEMPERATURES
   WARM INTO THE MID 60S TO LOWER 80S...A RELATIVELY LONG DURATION OF
   NEAR CRITICALLY LOW RH SHOULD OCCUR AS VALUES DROP TO AROUND 15
   PERCENT FOR MUCH OF THE AFTERNOON. THE COMBINATION OF A WEAKENING
   SURFACE PRESSURE GRADIENT AND GRADUAL SHIFTING OF THE STRONGEST
   MID-LEVEL WINDS OFFSHORE SHOULD LEAD TO WEAKER WINDS BY LATE
   AFTERNOON. HOWEVER...STEEPENING LOW-LEVEL LAPSE RATES WILL INCREASE
   MECHANICAL MIXING AND LIKELY KEEP SUSTAINED WINDS OF 20 TO 25 MPH
   THROUGH MOST OF THE DAY. OVERNIGHT...WINDS SHOULD BECOME MORE ELY
   AND WEAKEN MOST SUBSTANTIALLY ACROSS SWRN ORE AS THE UPPER LOW
   TRACKS FURTHER WSW. ACROSS NRN CA...WIND GUSTS SHOULD NOT BE QUITE
   AS STRONG AS THIS MORNING. AREAS IMMEDIATELY W OF THE SIERRA AND
   COASTAL MTNS SHOULD STILL MAINTAIN RELATIVELY POOR RH RECOVERIES AND
   GUSTS AROUND 30 MPH.

   INTENSIFY OVER THE GREAT LAKES REGION WITH AN ASSOCIATED COLD FRONT
   SURGING SEWD ACROSS THE CNTRL CONUS TOWARDS THE ERN SEABOARD AND
   GULF COAST.

   PRESSURE GRADIENT WANES...LOW-LEVEL WINDS WILL CONTINUE TO GRADUALLY
   WEAKEN ACROSS NRN CA...W OF THE NRN SIERRAS. STILL...LOCALLY GUSTY
   DOWNSLOPE WINDS IN COMBINATION WITH LOW RH MAY CONTINUE...ESPECIALLY
   IN THE FAR NRN SACRAMENTO VALLEY. TEMPERATURES WILL WARM INTO THE
   70S TO MIDDLE 80S WITH RH VALUES AROUND 15 PERCENT DURING THE
   AFTERNOON HOURS. HOWEVER...SUSTAINED WINDS WILL LIKELY REMAIN BELOW
