   VALID 091200Z - 101200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER TROUGH WILL PROGRESS EWD ACROSS THE PAC NW/NRN ROCKIES
   THROUGH THE PERIOD. AN INCREASE IN ONSHORE WINDS ALONG WITH EFFECTS
   FROM COLD FRONTAL PASSAGE WILL AID IN ABOUT A 5 DEGREE COOL DOWN
   FROM YESTERDAY OVER MOST OF WRN CA...ORE AND WA. ANOTHER DAY OF
   MODERATE WINDS WILL OCCUR FROM THE NRN GREAT BASIN INTO THE NRN
   ROCKIES IN ASSOCIATION WITH THE UPPER TROUGH PASSAGE.
   ADDITIONALLY...WLY FLOW OVER THE NRN/CNTRL ROCKIES WILL SUSTAIN THE
   LEE TROUGH OVER THE HIGH PLAINS. MODERATE PRESSURE GRADIENT BETWEEN
   THE LEE TROUGH AND SFC RIDGE OVER MS RIVER VALLEY WILL AID IN
   MODERATE SLY WINDS OVER THE CENTRAL PLAINS.  OTHERWISE...AN UPPER
   RIDGE WILL REMAIN IN PLACE OVER THE SWRN STATES AND SUPPORT WARM AND
   DRY AIR OVER MUCH OF THE WEST INTO THE SRN HIGH PLAINS WITH MIN RH
   READINGS FROM 10 TO 20 PERCENT. THE EXCEPTION TO THIS WILL BE OVER
   THE LOWER CO RIVER VALLEY WHERE ISOLATED-SCT WET THUNDERSTORMS WILL
   AGAIN OCCUR.
   
   ...NRN GREAT BASIN/NRN ROCKIES...
   AHEAD OF A SHORTWAVE TROUGH...WARM/DRY AIR WILL RESIDE OVER THE
   REGION...WITH MIN RH READINGS FROM 15-20 PERCENT. DESPITE STRONGER
   MID LEVEL FLOW OVER THE REGION THAN YESTERDAY...RECENT MODEL
   FORECASTS INDICATE WEAK SURFACE PRESSURE GRADIENT RESPONSE.
   SUSTAINED WINDS IN THE 15-20 MPH RANGE WILL BE LIKELY FROM NERN
   CA/NWRN NV INTO SRN ID/WY AND WRN MT DURING THE AFTERNOON/EVENING.
   LACK OF STRONGER WINDS WILL PRECLUDE A CRITICAL FIRE WEATHER THREAT.
   
   
   ...CENTRAL PLAINS...
   SUSTAINED WINDS FROM 15 TO 20 MPH WITH GUSTS OVER 25 MPH ARE
   ANTICIPATED OVER THE CENTRAL PLAINS TO THE EAST OF A LEE TROUGH AS
   PRESSURE GRADIENT STRENGTHENS. MIN RH READINGS WILL BE RELATIVELY
   LOW FROM 25 TO 30 PERCENT.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0418 AM CDT THU SEP 09 2004
   
   VALID 101200Z - 111200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   UPPER TROUGH OVER THE NRN ROCKIES WILL MOVE EWD INTO THE NRN PLAINS
   THROUGH THE PERIOD. MODERATE WINDS WILL AGAIN BE LIKELY OVER THE NRN
   GREAT BASIN INTO THE NRN ROCKIES. ALONG WITH LOW RH READINGS...NEAR
   CRITICAL FIRE WEATHER CONDITIONS ARE ANTICIPATED AS ON DAY ONE. 
   FARTHER EAST...A MODERATE SOUTH WIND AND LOW RH READINGS WILL AGAIN
   OCCUR EAST OF A LEE TROUGH OVER THE CENTRAL PLAINS. OTHERWISE...A
   BROAD RIDGE WILL REMAIN OVER THE SWRN STATES ALLOWING FOR ABOVE
   NORMAL TEMPERATURES...LOW RH READINGS AND LIGHT WINDS ACROSS MOST
   THE WEST. THE EXCEPTION WILL BE OVER THE COLORADO RIVER VALLEY
   REGION...WHERE ISOLATED WET THUNDERSTORMS WILL BE PRESENT
   
   ...NRN GREAT BASIN/NRN ROCKIES...
   AS ON DAY ONE...SUSTAINED WLY WINDS FROM 15 TO 20 MPH ARE EXPECTED
   SOUTH OF A FRONTAL BOUNDARY FROM NRN NV INTO WY. WARM TEMPERATURES
   ALONG WITH LOW DEWPTS IN THE 20S/30S WILL AID IN MIN RH READINGS
   FROM 10-15 PERCENT. LACK OF STRONGER WINDS WILL PRECLUDE A CRITICAL
   FIRE WEATHER THREAT.
   
   ...CENTRAL PLAINS...
   MODERATE SLY WINDS AROUND 20 MPH WITH GUSTS AROUND 30 MPH WILL OCCUR
   OVER THE CENTRAL PLAINS TO THE EAST OF A LEE TROUGH DURING THE
   AFTERNOON/EVENING. MIN RH READINGS WILL BE FROM 20-25 PERCENT.
