   DAY 1 FIRE WEATHER OUTLOOK...REF AWIPS GRAPHIC PMWE98 KWNS
   VALID 231200-241200
     
   ...NO LARGE-SCALE SIGNIFICANT FIRE WEATHER CONDITIONS EXPECTED...
     
   ...SYNOPSIS... 
   LITTLE CHANGE IN LARGE-SCALE PATTERN EXPECTED DURING THE DAY ONE
   FORECAST PERIOD. LEFTOVER MID-UPPER LVL SYSTEM PRESENTLY IN SCNTRL
   MT IS EXPECTED TO MOVE ENEWD TO AROUND GGW BY 24/00Z WITH HIGH
   PRESSURE IN ITS WAKE EXTENDING FROM NCNTRL CO NWWD THRU NRN
   UT...WRN WY...INTO NCNTRL ID. A SHORTWAVE TROUGH IS FORECAST TO
   ARRIVE INLAND FROM THE PACIFIC INTO NCNTRL CA BY 24/06Z AND WILL
   SPREAD INTO SERN ORE/NRN NV BY 24/12Z. BY 24/00Z...SFC LOW WILL BE
   IN CNTRL SD WITH LOW-LVL ELY FLOW AND WIDESPREAD SHWRS/TSTMS FROM
   THE NRN LAKES WWD INTO NRN MT. 
   
   ...WY...
   PARTS OF WY WILL EXPERIENCE WIND SPEEDS FROM 5-10 MPH FASTER THAN
   ON SATURDAY ESPECIALLY ACROSS ECNTRL PORTIONS OF THE STATE. EXPECT
   WSWLY SUSTAINED WINDS FROM 10-20 MPH OUT AHEAD OF A DISSIPATING
   COLD FRONT BEFORE WINDS WEAKEN AND TURN NNWLY OVERNIGHT INTO
   MONDAY. TEMPERATURES WILL REACH INTO THE MIDDLE-UPPER 80S AS RH
   VALUES WILL RANGE BETWEEN 15-20 PERCENT. SOME DRY TSTMS ARE
   POSSIBLE IN CNTRL/NCNTRL PARTS TODAY...BUT THEY SHOULD REMAIN
   RATHER ISOLATED...WITH WETTING RAINS EXPECTED MAINLY ALONG WY/MT
   BORDER AND FURTHER NORTH. WITH AN EXTREME LONG-TERM DROUGHT IN MUCH
   OF WY...SOME CONCERN IS WARRANTED TODAY...HOWEVER THE MARGINALITY
   OF THE LARGE-SCALE WINDS WILL PRECLUDE A CRITICAL ISSUANCE.   
   
   ...FOUR CORNERS REGION...
   WINDS WILL BE MUCH WEAKER TODAY AS LINGERING EFFECTS OF DEPARTED
   MID-UPPER LVL IMPULSE HAVE MOVED INTO THE NRN ROCKIES/WRN HIGH
   PLAINS. RH VALUES WILL CONTINUE LOW /10-20 PERCENT/ WITH NO SIGNS
   OF MONSOON AT THIS TIME. EXPECT WSWLY/WLY SUSTAINED WINDS FROM 5-15
   MPH WITH AFTERNOON SFC HIGHS FROM 85-90 DEGREES. MID-LVL LAPSE
   RATES WILL CONTINUE TO BE VERY STEEP AND MID-HIGH LVL HAINES
   INDICES ARE FORECAST TO BE EXTREME...INDICATING THE ABILITY OF ANY
   ONGOING FIRES TO CONTINUE/BECOME MORE PLUME-DOMINATED THROUGH THE
   DAY ONE PERIOD.

   500 AM CDT SUN JUN 23 2002
     
   DAY 2 FIRE WEATHER OUTLOOK...REF AWIPS GRAPHIC PMWI98 KWNS
   VALID 241200-251200
     
   ...NO LARGE-SCALE SIGNIFICANT FIRE WEATHER CONDITIONS EXPECTED...
     
   ...SYNOPSIS... 
   SHORTWAVE TROUGH FROM THE NRN PACIFIC WILL TRANSLATE FROM NRN
   NV/SRN ORE AT 24/12Z TO SRN MT/NRN WY BY 25/00Z WHILE RIDGING
   BUILDS THROUGHOUT THE REMAINDER OF THE SWRN U.S. INTO THE CNTRL
   ROCKIES. NERN MT MID-UPPER LVL LOW WILL MOVE EWD FROM NERN MT TO
   WRN ONTARIO BY THE END OF THE PERIOD WITH AN ASSOCIATED COLD FRONT
   PROGGED TO STRETCH THRU THE WRN GREAT LAKES REGION. HIGH PRESSURE
   IN BOTH THE MID-LEVELS AND AT THE SFC WILL YIELD LIGHT WINDS
   THROUGHOUT THE MAJORITY OF THE SWRN STATES INTO THE CNTRL ROCKIES
   DURING DAY TWO. MODELS DO HINT THAT A WEAK SHORTWAVE TROUGH COULD
   TRANSLATE THRU CNTRL/ERN AZ AFTER 25/00Z INTO TUE MRNG...POSSIBLY
   INHIBITING RH RECOVERIES...BUT CONFIDENCE AT THIS TIME IS NOT TOO
   STRONG. 
   
   ...WY...
   MODELS INDICATE THE POSSIBILITY OF SOME DRY TSTMS IN PARTS OF
   CNTRL/NCNTRL WY ON MONDAY. FORECAST SOUNDINGS SHOW INVERTED V
   PROFILES WITH AOA 9.5 C/KM 700-500 MB LAPSE RATES AND PW VALUES
   AROUND A HALF AN INCH. AT THIS POINT...THESE STORMS COULD BE RATHER
   ISOLATED AND WILL OPT TO VIEW NEWER MODEL DATA BEFORE CONTEMPLATING
   ANY CRITICAL ISSUANCE.
