   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK

   VALID 291200Z - 301200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER RIDGE WILL SLOWLY BUILD OVER THE WRN CONUS TODAY. A WEAK
   UPPER SYSTEM WILL ROTATE AROUND THE WRN PERIPHERY OF THIS UPPER
   RIDGE FROM WRN NV INTO SERN ORE. AHEAD OF THIS FEATURE...ISOLATED
   DRY TSTMS ARE EXPECTED OVER THE NWRN GREAT BASIN. OTHERWISE...WELL
   ABOVE NORMAL TEMPERATURES WILL OCCUR OVER MUCH OF THE WRN STATES.
   SCT TSTMS WILL OCCUR FROM THE SRN PLAINS INTO SERN STATES THROUGH
   MUCH OF THE PERIOD ASSOCIATED WITH A COLD FRONT...AND SEVERAL WEAK
   UPPER SYSTEMS.
   
   ...NWRN GREAT BASIN...
   AN UPPER LEVEL SYSTEM LOCATED OVER THE SIERRA NEVADA /PER SATELLITE
   IMAGERY/ WILL LIFT NWD INTO THE NWRN GREAT BASIN TODAY. INCREASING
   MID LEVEL MOISTURE ABOVE A DEEPLY MIXED/DRY BOUNDARY LAYER AIRMASS
   WILL SUPPORT TSTMS WITH LITTLE OR NO RAINFALL. ALTHOUGH SCT TSTMS
   ARE EXPECTED...INSUFFICIENT COVERAGE WILL PRECLUDE A CRITICAL DRY
   TSTM THREAT.

   DAY 2 FIRE WEATHER OUTLOOK

   0437 AM CDT WED AUG 29 2007
   
   VALID 301200Z - 311200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR DRY TSTMS OVER THE INTERIOR PAC
   NW/NRN ROCKIES REGION...
   
   ...SYNOPSIS...
   AN UPPER RIDGE WILL REMAIN THE DOMINANT UPPER LEVEL FEATURE OVER THE
   WRN AND CENTRAL CONUS TOMORROW. AN UPPER LEVEL TROUGH WILL MOVE INTO
   THE PAC NW LATE IN THE PERIOD. THE INTERACTION OF ANOTHER SRN STREAM
   SYSTEM AND MID LEVEL MOISTURE MOVING NWD THROUGH THE NRN GREAT BASIN
   WILL SUPPORT SCT-NMRS DRY TSTMS AND A CRITICAL FIRE WEATHER THREAT.
   ELSEWHERE ACROSS THE NATION...SCT TSTMS WILL AGAIN OCCUR FROM THE
   SRN PLAINS INTO THE SERN STATES.
   
   ...CRITICAL FIRE WEATHER AREA - INTERIOR PAC NW/NRN ROCKIES...
   
   PRIMARY CONDITIONS: NUMEROUS DRY TSTMS
   
   A SUBTLE UPPER SYSTEM MOVING NWD THROUGH THE NWRN GREAT BASIN WILL
   SUPPORT ONGOING SCT DRY TSTMS EARLY IN THE PERIOD OVER SERN ORE/SWRN
   ID. A STRONGER UPPER SYSTEM WILL DIG SEWD AND APPROACH THE WRN COAST
   OF B.C THROUGH TOMORROW. AS THIS OCCURS...ANOTHER SUBTLE UPPER
   SYSTEM /CURRENTLY SEVERAL HUNDRED MILES SW OF SRN CA/ WILL
   ACCELERATE NEWD FROM OFF THE NRN CA COAST INTO THE INTERIOR PAC
   NW/NRN ROCKIES DURING THE PERIOD. AS THIS UPPER SYSTEM INTERACTS
   WITH NWD MOVING MID LEVEL MOISTURE...IT WILL SUPPORT TSTM
   DEVELOPMENT FROM ERN ORE/WA INTO WRN ID BY THE AFTERNOON. GIVEN THE
   PRESENCE OF A DEEPLY MIXED DRY/HOT LOW LEVEL AIRMASS...MOST OF THE
   TSTMS ARE EXPECTED TO BE DRY. WITH INCREASING LARGE SCALE
   ASCENT...TSTM COVERAGE WILL BE SUFFICIENTLY HIGH TO WARRANT A
   CRITICAL FIRE WEATHER THREAT. DRY TSTMS ARE EXPECTED TO MOVE INTO
   WRN MT OVERNIGHT...BEFORE DIMINISHING IN AREAL COVERAGE.
