   ...NO LARGE-SCALE SIGNIFICANT FIRE WEATHER CONDITIONS EXPECTED...
     
   ...SYNOPSIS... 
   
   A 70KT 500MB JET ENTERING ALONG THE ORE COASTLINE THIS MORNING WILL
   TRANSLATE SEWD INTO THE GREAT BASIN BY THE END OF THE PERIOD. THIS
   FEATURE WILL RESULT IN THE DEVELOPMENT OF A STRONG AND BROAD UPPER
   TROUGH ACROSS THE INTERMOUNTAIN WEST. WHILE THE TROUGH WILL BRING
   COOLER AND MOISTER CONDITIONS TO THE CENTRAL AND NRN ROCKIES AND
   NWRN STATES...A TIGHTENING HEIGHT GRADIENT ON THE SRN PERIPHERY OF
   THE TROUGH WILL RESULT IN A STRENGTHENING OF WESTERLY WINDS. BY
   THIS EVENING...AN ELONGATED BELT OF 500MB WINDS IN THE 45-50KT
   RANGE IS EXPECTED ACROSS THE SRN GREAT BASIN EWD ACROSS THE FOUR
   CORNERS/SRN ROCKIES AREA.
   
   ...SRN ROCKIES...  
   
   A CONSIDERABLE INCREASE IN WIND IS ANTICIPATED TODAY ACROSS THE SRN
   ROCKIES REGION. DAYTIME MIXING WILL BRING SWLY TO WLY SURFACE WINDS
   OF 20-30 MPH IN SOME AREAS...PARTICULARLY AT HIGHER ELEVATIONS IN
   SRN UT...NRN AZ...NRN NM...AND SRN CO. MINIMUM RH VALUES WILL BE
   LOW...RANGING FROM 10-20 PERCENT AS LOW ELEVATION HIGH TEMPERATURES
   GENERALLY REACH THE 80S. DESPITE FAVORABLE AMBIENT WEATHER
   CONDITIONS THIS PERIOD...OVERALL FUEL CONDITIONS DO NOT WARRANT A
   CRITICAL FIRE WEATHER AREA. WIDESPREAD AREAS OF ERN AZ...NM...AND
   SRN CO HAVE RECORDED IN EXCESS OF 1 INCH OF RAINFALL DURING THE
   PAST 7 DAYS PER NOAA/CPC WEEKLY RAINFALL DEPICTION...MITIGATING THE
   LARGE-SCALE FIRE WEATHER THREAT. GIVEN THE COMPLEX OROGRAPHY...
   LOCAL FUEL CONDITIONS MAY VARY AND WARRANT HEIGHTENED AWARENESS
   WITH THE STRONG WINDS AND LOW RH VALUES ANTICIPATED THIS PERIOD.

   DAY 2 FIRE WEATHER OUTLOOK...REF AWIPS GRAPHIC PMWI98 KWNS
   VALID 181200-191200
     
   ...NO LARGE-SCALE SIGNIFICANT FIRE WEATHER CONDITIONS EXPECTED...
     
   ...SYNOPSIS... 
   
   DURING THE DAY 2 PERIOD...UPPER-LEVEL TROUGH WILL CONTINUE TO
   AMPLIFY ACROSS THE CENTRAL AND SRN ROCKIES. AT THE BASE OF THE
   TROUGH...VERY STRONG MID-LEVEL HEIGHT GRADIENT AND 50-60KT 500MB
   WINDS WILL PERSIST ACROSS AZ AND SRN NM...PRODUCING AREAS OF STRONG
   SURFACE WINDS AND DRY/LOW RH CONDITIONS.    
   
   ...AZ...NM...AND SWRN TX...
   
   THE POTENTIAL FOR MODERATE TO STRONG SURFACE WINDS WILL CONTINUE
   ACROSS PORTIONS OF THE REGION OWING TO UPPER-LEVEL TROUGH OVER THE
   AREA. THE TROUGH WILL BRING COOLER TEMPERATURES TO NRN AZ AND NRN
   NM...WITH TEMPERATURES LIKELY 5-10F COOLER IN THESE AREAS. THE  
   MOST SIGNIFICANT FIRE WEATHER CONDITIONS WILL LIKELY BE ACROSS 
   SRN SECTIONS OF NM AND SWRN TX...WHERE MINIMUM RH VALUES IN THE 10-
   15 PERCENT RANGE AND WLY WINDS OF 20-30 MPH...WITH GUSTS TO 40 MPH
   IN THE DAVIS MTNS...ARE POSSIBLE. HIGH TEMPERATURES WILL BE NEAR
   SEASONAL LEVELS. RECENT RAINFALL SUGGESTS OVERALL FUEL CONDITIONS
   ARE MOIST. THIS WILL MITIGATE ISSUANCE OF A LARGE-SCALE CRITICAL
   FIRE WEATHER AREA AT THIS TIME.
