   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0403 AM CDT SAT SEP 10 2005
   
   VALID 101200Z - 111200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   EARLY MORNING WATER VAPOR IMAGERY INDICATE AT LEAST A COUPLE OF
   SMALLER SCALE WAVES MOVING THROUGH THE LARGE WRN TROUGH. THE LEAD
   SHORTWAVE TROUGH NOW ENTERING SW UT WILL TRACK ACROSS WY TODAY...AS
   THE MID LEVEL WINDS INCREASE TO AROUND 70 KT IN RESPONSE. AT THE
   SFC...LOW PRESSURE WILL DEEPEN AS IT MOVES ACROSS WRN ND. STRONG
   COLD FRONT NOW EXTENDING FROM THE GREAT BASIN INTO NW WY WILL MOVE
   ACROSS THE WRN DAKOTAS WHILE THE SRN PORTION OF THE FRONT BECOMES
   STATIONARY. VERY STRONG GRADIENT WINDS OCCURRING WITH THIS SYSTEM
   WILL INCREASE THE THREAT FOR WIND DRIVEN FIRES. HOWEVER...RH VALUES
   WILL MITIGATE THE OVERALL POTENTIAL FOR CRITICAL FIRE WEATHER
   CONDITIONS.
   
   ...WY INTO THE WRN DAKOTAS...
   VERY STRONG SFC WINDS WILL DEVELOP AS A RESULT OF THE INTENSE
   PRESSURE GRADIENT. IN ADDITION DEEP BOUNDARY LAYER MIXING ASSOCIATED
   WITH STEEP LAPSE RATES WILL ALLOW HIGHER MOMENTUM FLOW FROM MID
   LEVELS TO BE REALIZED AT THE SFC. SUSTAINED WINDS OF 20-30 MPH WITH
   HIGHER GUSTS TO 40-45 MPH ARE POSSIBLE ESPECIALLY OVER FAVORED
   TERRAIN AREAS ACROSS WY. HOWEVER...MINIMUM RH VALUES ARE EXPECTED TO
   BE OVER 15 PERCENT WITH MAX TEMPS ONLY IN THE 70S/LOWER 80S. AREAS
   ACROSS THE HIGH PLAINS WILL BE IN THE WARM SECTOR AND MAX TEMPS WILL
   RISE INTO THE 90S WITH SIGNIFICANTLY DRIER CONDITIONS.

   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   IT APPEARS THAT WHILE INITIAL SHORTWAVE TROUGH WILL MOVE INTO
   MANITOBA BY SUN EVENING...A DEEP LOW PRESSURE SYSTEM WILL BE
   MAINTAINED IN THE MID LEVELS ACROSS THE PACIFIC NORTHWEST. STRONGLY
   CYCLONIC JET STREAM WILL ALLOW THIS SYSTEM TO CONTINUE TO DIG SWD
   ACROSS NRN CA. SFC TEMPS WILL BE A FEW DEGREES BELOW NORMAL ACROSS
   MUCH OF THE PACIFIC NORTHWEST...WITH SOME PORTIONS OF SCNTRL ORE/NE
   CA EXPERIENCING THE FIRST FREEZING TEMPS OF THE SEASON ON SUNDAY
   MORNING. FRONTAL ZONE AT THE SFC WILL EXTEND FROM A LOW IN CNTRL SD
   THROUGH CNTRL UT AND INTO THE GREAT BASIN.
   
   ...WY/NRN UT...
   BREEZY SFC WINDS WILL AGAIN DEVELOP ACROSS THE REGION...GENERALLY
   RANGING FROM 15-25 MPH WITH HIGHER GUSTS. COOLER TEMPS IN THE 70S
   WILL PREVENT MINIMUM RH VALUES FROM FALLING BELOW 15 PERCENT ACROSS
   MOST AREAS.
