   VALID 171200Z - 181200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE INTERIOR PAC NW
   AND THE NRN GREAT BASIN...
   
   ...SYNOPSIS...
   AHEAD OF AN UPPER TROUGH MOVING THROUGH NRN CA EARLY THIS
   MORNING...SCT DRY TSTMS WILL BE POSSIBLE FROM NRN NV INTO ERN
   ORE/WRN ID THROUGH THE PERIOD SUPPORTING A CRITICAL FIRE WEATHER
   THREAT. NORTH OF THIS SYSTEM...HIGH HAINES INDICES /6/ COMBINED WITH
   VERY DRY/ABOVE NORMAL TEMPERATURES WILL SUPPORT NEAR CRITICAL FIRE
   WEATHER CONDITIONS OVER MUCH OF THE REMAINDER OF THE PAC NW.
   ELSEWHERE ACROSS THE WEST...SCT MAINLY WET TSTMS WILL BE POSSIBLE
   OVER THE SRN GREAT BASIN/FOUR CORNER AREA ASSOCIATED WITH A WEAK
   UPPER LEVEL SYSTEM. BROAD SFC/UPPER LEVEL HIGH PRESSURE WILL RESULT
   IN DRY CONDITIONS/LIGHT WINDS ACROSS MOST OF THE NATION EAST OF THE
   ROCKIES.
   
   ...CRITICAL FIRE WEATHER AREA - PORTIONS OF THE INTERIOR PAC NW AND
   NRN GREAT BASIN...
   
   PRIMARY CONDITIONS: SCT DRY TSTMS
   
   AHEAD OF AN UPPER TROUGH...MODEST UPPER LEVEL FORCING COMBINED WITH
   MID LEVEL INSTABILITY WILL SUPPORT SCT TSTMS OVER THE REGION THIS
   AFTERNOON. DRY LOW LEVELS AND HIGH CLOUD BASES WILL COMBINE TO
   PRODUCE LITTLE RAINFALL AND POTENTIAL FOR MAINLY DRY TSTMS WITH
   GUSTY/ERRATIC WINDS.
   
   ...REMAINDER OF PAC NW...
   NORTH OF THE DRY TSTM THREAT AREA...A VERY DRY AIRMASS AND ABOVE
   NORMAL TEMPERATURES/LIGHT WIND FIELDS WILL SUPPORT A HIGH HAINES
   INDEX OVER THE REGION TODAY. THIS WILL LEAD TO THE POTENTIAL FOR
   PLUME DOMINATED FIRE GROWTH WITH ANY LARGE FIRE.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0357 AM CDT WED SEP 17 2008
   
   VALID 181200Z - 191200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER TROUGH WILL WEAKEN AS IT MOVES THROUGH THE NRN ROCKIES
   TOMORROW. AHEAD OF THIS SYSTEM...ISOLATED DRY TSTMS WILL BE POSSIBLE
   FROM THE NERN GREAT BASIN INTO THE NRN ROCKIES. FURTHER
   WEST...ANOTHER UPPER TROUGH WILL MOVE TOWARDS THE CA/ORE COAST.
   ISOLATED DRY TSTMS WILL ALSO BE POSSIBLE AHEAD OF THIS SYSTEM OVER
   NWRN CA/SWRN ORE LATE IN THE PERIOD. FURTHER EAST...THE UPPER/SFC
   PATTERN WILL REMAIN SIMILAR TO TODAY WITH HIGH PRESSURE DOMINATING
   AREAS EAST OF THE ROCKIES. THIS WILL PRECLUDE ANY OTHER CRITICAL
   FIRE WEATHER POTENTIAL.
   
   ...NRN ROCKIES/ERN GREAT BASIN...
   AHEAD OF A WEAKENING SHORTWAVE TROUGH...ISOLATED DRY TSTMS WILL BE
   POSSIBLE FROM ERN UT/WRN WY AND ERN ID. LACK OF GREATER CONVECTIVE
   COVERAGE WILL PRECLUDE A CRITICAL FIRE WEATHER OUTLOOK AREA.
   
   ...SWRN ORE/NWRN CA...
   AHEAD OF A SEASONABLY STRONG UPPER TROUGH...ISOLATED TSTMS WILL BE
   POSSIBLE LATE IN THE PERIOD AS FORCING INTERACTS WITH STEEP LAPSE
   RATES/MID LEVEL MOISTURE. DRY LOW LEVELS WOULD LIMIT RAINFALL AMTS
   AND LEAD TO POTENTIAL FOR DRY LIGHTNING. HOWEVER...LIMITED COVERAGE
   OF TSTMS EXPECTED ATTM WILL PRECLUDE A CRITICAL FIRE WEATHER OUTLOOK
   AREA.
