   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0352 AM CST WED FEB 11 2004
   
   VALID 111200Z - 121200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   STRONG UPPER LOW/TROUGH OVER THE NRN ROCKIES WILL DIVE SWD INTO THE
   FOUR CORNERS BY THE END OF THE PERIOD. BEHIND THIS TROUGH...ARCTIC
   HIGH PRESSURE MOVING INTO THE NRN GREAT BASIN/CENTRAL ROCKIES WILL
   AID IN STRENGTHENING THE NELY PRESSURE GRADIENT OVER SRN CA/LOWER
   COLORADO RIVER VALLEY. NEAR CRITICAL FIRE WEATHER CONDITIONS WILL
   OCCUR AFTER 12/09Z OVER PORTIONS OF SRN CA AS SUSTAINED WINDS
   INCREASE TO OVER 20 MPH WITH GUSTS OVER 40 MPH ALONG WITH POOR RH
   RECOVERY.
   
   ...COASTAL RANGES/VALLEYS OF SRN CA...
   SURFACE PRESSURE GRADIENT WILL INTENSIFY OVER THE AREA AS HIGH
   PRESSURE OVER THE NRN ROCKIES MERGES WITH ANTECEDENT HIGH PRESSURE
   OVER THE GREAT BASIN. OFFSHORE SUSTAINED WINDS WILL INCREASE TO
   BETWEEN 20 AND 30 MPH WITH GUSTS OVER 50 MPH AFTER 12/09Z...BEHIND A
    COLD FRONT. DESPITE POOR RH RECOVERY ANTICIPATED...THE LACK OF A
   LONGER DURATION CRITICAL FIRE WEATHER THREAT WILL PRECLUDE AN
   OUTLOOK FOR THIS AREA.
   
   ...LOWER COLORADO RIVER VALLEY...
   NLY WINDS WILL INCREASE BEHIND A COLD FRONT OVER THE LOWER COLORADO
   RIVER VALLEY BETWEEN 11/00Z AND 12/03Z. SUSTAINED WINDS BETWEEN 20
   AND 25 MPH WITH GUSTS TO 35 MPH WILL BE LIKELY. RH READINGS AROUND
   20 PERCENT DURING THIS TIME WILL PRECLUDE ANY CRITICAL FIRE WEATHER
   THREAT.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0351 AM CST WED FEB 11 2004
   
   VALID 121200Z - 131200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR COASTAL MTNS/VALLEYS OF SRN CA...
   ...CRITICAL FIRE WEATHER AREA FOR LOWER COLORADO RIVER VALLEY OF
   CA/AZ...
   
   ...SYNOPSIS...
   A STRONG MID/UPPER LEVEL TROUGH OVER THE FOUR CORNERS WILL SLOWLY
   PROGRESS SWD INTO THE SRN ROCKIES THROUGH THE PERIOD. A STRONG AREA
   OF HIGH PRESSURE CENTERED OVER THE GREAT BASIN/CENTRAL ROCKIES WILL
   AID IN A MODERATE OFFSHORE WIND EVENT OVER COASTAL AREAS OF SRN
   CA...ALONG WITH STRONG NLY WINDS OVER THE LOWER COLORADO RIVER
   VALLEY. THE COMBINATION OF THESE WINDS ALONG WITH LOW RH READINGS
   BETWEEN 10 AND 15 PERCENT WILL PROVIDE FOR A CRITICAL FIRE WEATHER
   THREAT TO THE REGION.
   
   ...CRITICAL FIRE WEATHER AREA 1 - COASTAL RANGES/VALLEYS OF SRN
   CA...
   
   PRIMARY CONDITIONS: SUSTAINED WINDS FROM 20 TO 30 MPH WITH GUSTS
   OVER 50 MPH
   
   OFFSHORE WINDS WILL CONTINUE TO INTENSIFY AT THE START OF THE PERIOD
   AND REMAIN STRONG THROUGH MOST OF THE DAY...WITH SOME DECREASE
   ANTICIPATED DURING THE AFTERNOON...BEFORE A REINTENSIFICATION IS
   EXPECTED OVERNIGHT. THE STRONGEST SUSTAINED WINDS ARE ANTICIPATED
   AFTER 13/00Z...WITH THE PASSAGE OF THE MAIN MID/UPPER LEVEL TROUGH.
   SUSTAINED WINDS WILL LIKELY AVERAGE DURING THE EVENT BETWEEN 20 AND
   30 MPH...WITH GUSTS OVER 50 MPH.
   
   ...CRITICAL FIRE WEATHER AREA 2 - LOWER COLORADO RIVER VALLEY...
   
   PRIMARY CONDITIONS: SUSTAINED NLY WINDS FROM 20 TO 30 MPH WITH GUSTS
   OVER 45 MPH
   
   SIMILAR TO THE OFFSHORE WINDS FARTHER WEST...STRONG NLY WINDS WILL
   OCCUR AS SURFACE HIGH PRESSURE BUILDS SWD INTO THE GREAT BASIN.
   ADDITIONALLY...ALONG THE WRN PERIPHERY OF THE UPPER TROUGH A
   COMBINATION OF STEEP LAPSE RATES AND UNIDIRECTIONAL WIND PROFILES
   FROM THE SURFACE UP TO MID LEVELS WILL AID IN VERY STRONG GUSTS OVER
   45 MPH...ESPECIALLY DURING THE AFTERNOON HOURS. STRONG DOWNWARD
   VERTICAL MOTION WILL FURTHER SUPPORT DRYING LOW LEVELS AND MIN RH
   READINGS AROUND 10 PERCENT...WITH POOR RECOVERY EXPECTED OVERNIGHT.
