   DAY 1 FIRE WEATHER OUTLOOK...REF AWIPS GRAPHIC PMWE98 KWNS
   VALID 101200-111200
     
   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE CENTRAL/SRN
   ROCKIES...
     
   ...SYNOPSIS... 
   STRONG MID LEVEL SHORTWAVE TROUGH/LOW CENTER WILL SHIFT SLOWLY
   ENEWD ACROSS THE NRN ROCKIES THROUGH THE PERIOD. ANOTHER DAY OF
   CRITICAL FIRE WEATHER CONDITIONS WILL BE PRESENT OVER PORTIONS OF
   THE CENTRAL AND SRN ROCKIES...WHERE VERY LOW RH AND MODERATELY
   STRONG WINDS WILL BE PRESENT. WINDS WILL DECREASE CONSIDERABLY
   TODAY OVER SERN UT AND NRN/CENTRAL AZ PRECLUDING A CRITICAL FIRE
   WEATHER THREAT TO THESE AREAS...DESPITE VERY LOW RH VALUES EXPECTED
   AGAIN. A BROAD UPPER RIDGE WILL DOMINATE THE REMAINDER OF THE
   COUNTRY...WITH NO FIRE WEATHER CONCERNS ANTICIPATED.
   
   ...CRITICAL FIRE WEATHER AREA 1 - SCENTRAL WY...WRN/CENTRAL
   CO...MUCH OF NRN/CENTRAL NM...
     
   PRIMARY CONDITIONS: / SUSTAINED WINDS FROM 20 TO 30 MPH WITH GUSTS
   TO 40 MPH / MINIMUM RH VALUES FROM 5 TO 15 PERCENT / HIGH HAINES
   INDEX...
   
   WINDS WILL BE SOMEWHAT LIGHTER OVER THE AREA TODAY FROM WHAT WAS
   OBSERVED YESTERDAY. HOWEVER...A DEEP LAYER OF NEAR DRY ADIABATIC
   LAPSE RATES WILL COMBINE WITH MODEST MID LEVEL WINDS ON THE SRN
   PERIPHERY OF STRONG UPPER LEVEL SYSTEM TO SUPPORT SUSTAINED SURFACE
   WINDS FROM 20 TO 30 MPH WITH GUSTS TO 40 MPH. MINIMUM RH VALUES
   WILL AGAIN BE VERY LOW RANGING FROM 5 TO 15 PERCENT. A SURFACE COLD
   FRONT WILL EXTEND FROM NCENTRAL CO SWWD INTO SWRN CO AT 10/12Z. AS
   THE MAIN SHORTWAVE TROUGH MOVES EWD ACROSS THE ROCKIES DURING THE
   DAY EXPECT THE FRONT TO BECOME STATIONARY TO THE WEST OF THE FRONT
   RANGE. MODERATELY STRONG PRESSURE FALLS SHOULD OCCUR OVER
   CENTRAL/SERN CO AIDING IN STRENGTHENING THE PRESSURE GRADIENT/LEE
   TROUGH OVER THE REGION FURTHER SUPPORTING CRITICAL LEVEL WIND
   SPEEDS. 
   
   EARLY MORNING SATELLITE IMAGERY INDICATED THE PRESENCE OF VERY DRY
   AIR AT MID AND HIGH LEVELS EXTENDING FROM SRN AZ NWD INTO
   CENTRAL/ERN CO. THE NWRN PERIPHERY OF THIS AIRMASS WAS IN PLACE
   OVER CENTRAL CO YESTERDAY WHICH AIDED IN PLUME DOMINATED FIRE
   GROWTH. ALTHOUGH THIS AIRMASS WILL SHIFT SLIGHTLY SEWD THROUGH THE
   DAY IN RESPONSE TO APPROACHING SHORTWAVE TROUGH...PORTIONS OF
   NRN/CENTRAL NM AND SCENTRAL CO WILL SEE HIGH HAINES INDICES AND THE
   POTENTIAL FOR PLUME DOMINATED FIRE GROWTH. FAIR TO GOOD RH RECOVERY
   IS EXPECTED OVER MOST OF CO OVERNIGHT AS THE FRONT MOVES SOUTH
   THROUGH THE STATE...WITH POOR RECOVERY EXPECTED OVER NM. WINDS
   SHOULD DECREASE TO UNDER CRITICAL LEVELS BY 11/04Z.
   
   ...NRN CA...
   MODEST OFFSHORE WINDS/POOR RH RECOVERY IS POSSIBLE AGAIN TONIGHT
   OVER PORTIONS OF THE CENTRAL/NRN CA COASTAL RANGE AND FOOTHILLS.
   MARGINAL NATURE OF SUSTAINED WINDS EXPECTED / 15-25 MPH / WILL
   PRECLUDE A CRITICAL FIRE WEATHER THREAT.

   DAY 2 FIRE WEATHER OUTLOOK...REF AWIPS GRAPHIC PMWI98 KWNS
   VALID 111200-121200
     
   ...NO LARGE-SCALE SIGNIFICANT FIRE WEATHER CONDITIONS EXPECTED...
     
   ...SYNOPSIS... 
   THE UPPER AIR PATTERN ACROSS THE COUNTRY WILL UNDERGO A TRANSITION
   DURING THE PERIOD...AS THE SHORTWAVE TROUGH OVER THE NRN ROCKIES AT
   THE START OF THE PERIOD MOVES EWD INTO THE NRN PLAINS BY 12/12Z.
   THE UPPER RIDGE WHICH HAS BEEN FIRMLY ENTRENCHED OVER THE SERN U.S
   FOR THE LAST SEVERAL DAYS WILL BEGIN TO BREAKDOWN AND RETROGRADE
   WWD INTO THE SRN PLAINS/DESERT SW REGION. WEAKENING MID LEVEL WINDS
   OVER THE CENTRAL/SRN ROCKIES AND DESERT SW WILL AID IN LITTLE TO NO
   FIRE WEATHER CONCERNS ACROSS THE AREA. ELSEWHERE ACROSS THE
   COUNTRY...MODERATE TO HIGH MINIMUM RH VALUES WILL AID IN NO FIRE
   WEATHER CONCERNS. 
   
   ...NM/SRN CO...
   THERE WILL BE SOME POTENTIAL FOR CRITICAL WIND SPEEDS FOR A FEW
   HOUR PERIOD DURING THE MID-LATE AFTERNOON HOURS ACROSS NRN NM AND
   SRN CO. ABOVE NORMAL TEMPERATURES WILL AID IN VERY LOW RH READINGS
   FROM 5 TO 10 PERCENT DURING THE AFTERNOON/EARLY EVENING. SUSTAINED
   WINDS FROM 20 TO 25 MPH WILL BE POSSIBLE BETWEEN 11/19Z AND 12/00Z.
   FATHER SOUTH...WINDS WILL BE LIGHTER...BUT ISOLATED DRY
   THUNDERSTORMS WILL BE POSSIBLE AS MID LEVEL MOISTURE INCREASES WITH
   ONSET OF MONSOONAL PATTERN. THE AREA WILL BE REEVALUATED FOR A
   POTENTIAL UPGRADE IN TOMORROW/S DAY ONE OUTLOOK.
