   DAY 1 FIRE WEATHER OUTLOOK RESENT 1
   NWS STORM PREDICTION CENTER NORMAN OK
   1026 AM CDT FRI SEP 11 2009
   
   VALID 111200Z - 121200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   ...RESENT PER REQUEST...
   
   AN UPPER LEVEL TROUGH CURRENTLY PROGRESSING SEWD INTO THE NRN HIGH
   PLAINS WILL GRADUALLY BEGIN TO CLOSE OFF AND STALL ROUGHLY OVER
   CNTRL SD BEFORE SLOWLY RETROGRADING WWD INTO THE NRN ROCKIES. BEHIND
   THIS...AMPLIFIED UPPER HIGH PRESSURE WILL LINGER OVER MUCH OF THE
   WEST...WITH ABOVE NORMAL TEMPERATURES AND DRY CONDITIONS AT THE
   SURFACE. LOCALLY GUSTY WINDS MAY BE POSSIBLE IN SRN CA AS WEAK
   OFFSHORE WINDS CONTINUE BETWEEN LOW PRESSURE OVER THE SRN CA
   DESERTS...AND SURFACE HIGH PRESSURE DEVELOPING SWD THROUGH THE
   ROCKIES AND INTO THE SOUTHWEST. HOWEVER...SUSTAINED WIND SPEEDS ARE
   EXPECTED TO REMAIN BELOW CRITICAL THRESHOLDS. MEANWHILE...A SERIES
   OF WEAK UPPER DISTURBANCES AND LINGERING MOISTURE WILL CONTINUE TO
   BRING THUNDERSTORMS TO MUCH OF AZ/NM/CO. IN CA...AN UPPER LOW
   OFFSHORE OF CNTRL CA WILL DRIFT TOWARDS THE COAST THROUGHOUT THE
   PERIOD. THIS MAY PROVIDE ENOUGH DESTABILIZATION FOR ISOLATED
   LIGHTNING STRIKES...ESPECIALLY AFTER DARK AS THE LOW MOVES CLOSER TO
   THE COAST. STRIKES WILL LIKELY BE PRIMARILY LIMITED TO OFFSHORE
   AREAS OF CNTRL/SRN CA...AS WELL AS THE SIERRAS. AS COVERAGE IS
   EXPECTED TO BE ONLY ISOLATED AT BEST...A CRITICAL AREA WILL NOT BE
   OUTLINED.

   DAY 2 FIRE WEATHER OUTLOOK RESENT 1
   NWS STORM PREDICTION CENTER NORMAN OK
   1029 AM CDT FRI SEP 11 2009
   
   VALID 121200Z - 131200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   ...RESENT PER REQUEST...
   
   A WEAK UPPER LOW WILL DRIFT INTO CNTRL CA...WHILE A STRONGER UPPER
   TROUGH APPROACHES THE PACIFIC NORTHWEST. MID LEVEL MOISTURE WILL
   CONTINUE TO INCREASE AHEAD OF THESE TWO SYSTEMS AS AN AREA OF RICHER
   MOISTURE NOTED ON WV/PWAT IMAGERY APPROACHES THE NORTHWESTERN
   COAST...WHILE MOISTURE FROM DECAYING T.S. LINDA STREAMS NEWD. BRIEF
   UPPER RIDGING WILL PRECEDE THESE TROUGHS...ALLOWING ABOVE NORMAL
   TEMPERATURES AND DRY CONDITIONS AT THE SURFACE TO CONTINUE. CURRENT
   FORECASTS INDICATE WEAK INSTABILITY THAT WOULD LIKELY BE MORE
   CONDUCIVE TO ISOLATED THUNDERSTORMS/LIGHTNING STRIKES...THOUGH GIVEN
   SEVERAL DAYS OF HOT/DRY CONDITIONS THIS WOULD STILL LEAD TO A FIRE
   THREAT. MUCH OF THE WEST WILL NEED TO BE MONITORED FOR POSSIBLE
   INCLUSION OF A DRY THUNDERSTORM AREA IN TOMORROW/S FORECAST...SHOULD
   INSTABILITY APPEAR TO BE GREATER THAN CURRENTLY FORECAST.
   THUNDERSTORMS WILL BE POSSIBLE THROUGH EARLY MORNING AND INTO D3.
   
   MEANWHILE FARTHER E...AN UPPER LOW IN THE NRN ROCKIES WILL CONTINUE
   TO SLOWLY RETROGRADE WWD THEN NWWD THROUGH THE PERIOD. ALTHOUGH THE
   SURFACE PRESSURE GRADIENT WILL INCREASE ACROSS THE ROCKIES AS LOW
   PRESSURE DEVELOPS OVER THE GREAT BASIN AND HIGH PRESSURE DEVELOPS
   OVER MUCH OF THE HIGH PLAINS...WINDS WILL BE MARGINAL AND RELATIVE
   HUMIDITIES WILL REMAIN ABOVE CRITICAL THRESHOLDS. DESPITE STRONGER
   ELY WINDS ABOVE THE SURFACE IN THE NRN ROCKIES...IT APPEARS THAT
   MOISTURE/LOW MIXING HEIGHTS WILL PREVENT THESE WINDS FROM REACHING
   THE SURFACE.
