   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0425 AM CDT MON AUG 29 2005
   
   VALID 291200Z - 301200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR NRN SIERRA/GREAT BASIN/NRN
   ROCKIES...
   
   ...SYNOPSIS...
   STRONG UPPER TROUGH IS QUICKLY APPROACHING THE PACIFIC NORTHWEST
   COAST EARLY THIS MORNING...WITH A MID LEVEL JET MAX OF 70-75 KT.
   MAIN TROUGH AXIS WILL MOVE INTO ALBERTA BY EARLY TUESDAY...BUT WINDS
   WILL INCREASE TODAY FROM THE GREAT BASIN INTO THE NRN ROCKIES IN
   ADVANCE OF THE SYSTEM. EARLY MORNING SFC ANALYSIS PLACES COLD FRONT
   ACROSS ERN WA/ERN ORE INTO NRN CA. COLD FRONT WILL MOVE INTO THE
   SNAKE RIVER VALLEY...EXTENDING FROM THE ERN MAGIC VALLEY INTO THE
   ERN GREAT BASIN BY 30/00Z. AHEAD OF THE FRONT...STRONG SW WINDS WILL
   DEVELOP WITH NUMEROUS GUSTS ABOVE 30 MPH LIKELY. ISOLD TSTMS ARE
   ALSO POSSIBLE ACROSS PORTIONS OF THE OUTLOOK AREA.
   
   ...CRITICAL FIRE WEATHER AREA 1 - NRN SIERRA/SE ORE/NRN AND CNTRL
   NV/CNTRL AND SRN ID/WRN AND CNTRL MT/NW UT/NW WY...
   
   PRIMARY CONDITIONS: SUSTAINED SFC WINDS 15-30 MPH WITH HIGHER
   GUSTS/MINIMUM RH VALUES BELOW 15 PERCENT/DRY FUELS
   
   MAIN FIRE WEATHER THREAT WILL BE STRENGTHENING SFC WINDS IN
   ASSOCIATION WITH INCREASING PRESSURE GRADIENT. SUSTAINED WINDS OF
   15-30 MPH ARE EXPECTED BY AFTN...WITH GUSTS ABOVE 40 MPH POSSIBLE
   GIVEN STRONG BOUNDARY LAYER MIXING TO NEARLY 500 MB. WINDS WILL
   CHANGE DIRECTION AFTER FROPA...GENERALLY FROM SW TO NW WHICH WILL
   PRESENT AN ADDITIONAL COMPLICATION TO ONGOING FIRE SUPPRESSION
   EFFORTS. FORECAST SOUNDINGS SUGGEST MAX TEMPS WILL RISE INTO THE
   MID/UPPER 80S ACROSS THE GREAT BASIN/SNAKE RIVER VALLEY WITH COOLER
   TEMPS ACROSS MT. BECAUSE OF THE SLOWER SYSTEM MOVEMENT...MUCH OF
   WY/SE MT WILL NOT BE INCLUDED IN THIS OUTLOOK AS THE STRONGEST WINDS
   WILL NOT AFFECT THESE AREAS UNTIL AFTER SUNSET INTO TUE.
   HOWEVER...SOME OF THE HOTTEST AND DRIEST CONDITIONS WILL BE OBSERVED
   TODAY ACROSS WY/SE MT. 
   
   FINALLY...TSTMS ARE POSSIBLE MAINLY IN THE LATE AFTN AND EVENING.
   ISOLD DRY LIGHTNING AND STRONG TSTM WIND GUSTS WILL BE THE MAIN FIRE
   WEATHER HAZARDS. MOISTURE WILL BE LIMITED SO COVERAGE IS EXPECTED TO
   BE MINIMAL.
   
   ...ERN MT/WRN DAKOTAS...
   AS RIDGE AXIS SHIFTS EWD IN ADVANCE OF WRN TROUGH...ABOVE
   NORMAL/RECORD HIGH TEMPS ARE POSSIBLE WITH VALUES WELL INTO THE 90S.
   IN ADDITION MINIMUM RH VALUES WILL FALL BELOW 15 PERCENT. SFC WINDS
   WILL INCREASE TO AROUND 15-25 MPH ACROSS THE REGION...THOUGH
   WIDESPREAD CRITICAL FIRE WEATHER CONDITIONS ARE NOT EXPECTED.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0426 AM CDT MON AUG 29 2005
   
   VALID 301200Z - 311200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   SHARPLY DEFINED WRN TROUGH AXIS WILL BE LOCATED ACROSS WRN ALBERTA
   EARLY TUESDAY MORNING AND WILL QUICKLY MOVE INTO MANITOBA BY WED.
   THE ASSOCIATED MID LEVEL JET MAX WILL AFFECT WY AND PORTIONS OF ERN
   MT THROUGH TUE AFTN/EVE...WHILE A VIGOROUS COLD FRONT MOVES EWD FROM
   SE MT/CNTRL WY INTO THE NRN PLAINS BY TUE AFTN. SFC WINDS ACROSS WY
   WILL BE QUITE STRONG...ESPECIALLY ACROSS THE BIG HORN BASIN INTO THE
   ERN WY PLAINS. HOWEVER...COOLER TEMPERATURES ARE EXPECTED ACROSS ERN
   MT/WY AND THE WRN DAKOTAS IN THE WAKE OF THE FRONT. MINIMUM RH
   VALUES WILL GENERALLY BE ABOVE 20-25 PERCENT DESPITE THE FACT THAT
   SFC WINDS WILL BE QUITE STRONG. ALTHOUGH THE INCREASED WINDS WILL
   PRESENT A FIRE WEATHER THREAT...CRITICAL FIRE WEATHER CONDITIONS ARE
   NOT EXPECTED GIVEN MARGINAL RH VALUES.
   
   ...ERN MT/WRN DAKOTAS/WY...
   UNFAVORABLE TIMING OF SFC COLD FRONT WILL LIKELY LIMIT THE POTENTIAL
   FOR CRITICAL FIRE WEATHER CONDITIONS TO DEVELOP ON TUE. FORECAST
   SOUNDINGS AND SFC FORECAST PROGS INDICATE SFC LOW WILL HAVE MOVED
   INTO WRN SD BY EARLY AFTN...WITH FRONT THROUGH CNTRL WY. ALTHOUGH
   GUSTY NW WINDS WILL OCCUR ACROSS ERN MT WITH WLY WINDS ACROSS
   WY...MAX TEMPS WILL ONLY BE IN THE 60S/70S...RESULTING IN RH VALUES
   ABOVE 20 PERCENT.
