   DAY 1 FIRE WEATHER OUTLOOK...REF AWIPS GRAPHIC PMWE98 KWNS
   VALID 171200-181200
     
   ...NO AREAS...
     
   ...SYNOPSIS... 
   A 700MB THERMAL RIDGE ACROSS THE DESERT SW WILL SPREAD EWD ACROSS
   THE SRN ROCKIES/SRN HIGH PLAINS AREA THIS PERIOD. THIS FEATURE WILL
   BE ASSOCIATED WITH ABOVE NORMAL TEMPERATURES AND VERY LOW MINIMUM
   RH VALUES. BETWEEN THIS RIDGE AND A BROAD BAROCLINIC TROUGH ACROSS
   THE NWRN CONUS...A SHORT-WAVE TROUGH/MID-LEVEL JET MAX WILL
   TRANSLATE NEWD ACROSS THE SRN GREAT BASIN THIS AFTERNOON INTO THIS
   EVENING. 
   
   ...FOUR CORNERS AREA...  
   BY AFTERNOON...AN AREA OF SWLY WINDS BETWEEN 15-25 MPH WILL DEVELOP
   ACROSS CENTRAL/SRN UT...NRN AZ...NWRN NM...AND WRN CO IN RESPONSE
   TO INCREASING WINDS ALOFT AND VERTICAL MIXING ASSOCIATED WITH
   AFTERNOON HEATING AND STEEPENING LOW-LEVEL LAPSE RATES. WINDS COULD
   LOCALLY REACH 30-35 MPH ACROSS SRN UT BENEATH ANTICIPATED CORE OF
   STRONGEST UPPER FLOW. A MITIGATING FACTOR IN SEVERITY OF FIRE
   WEATHER CONDITIONS WILL BE MID-UPPER LEVEL CLOUDS SPREADING NEWD
   TOWARD THE GREAT BASIN AREA EARLY THIS MORNING. NUMERICAL MODELS
   ARE CONSISTENT IN SHOWING BROKEN TO OVERCAST CONDITIONS IN
   CENTRAL/SRN UT WHICH WILL HOLD TEMPERATURES IN THE MID TO UPPER 70S
   AND MINIMUM RH VALUES AROUND 20 PERCENT. THIS WILL PRECLUDE A
   CRITICAL FIRE WEATHER AREA. FURTHER SOUTH....MUCH WARMER
   TEMPERATURES ARE EXPECTED ACROSS AZ/NM...WITH VERY LOW MINIMUM RH
   VALUES OF 8-15 PERCENT. HOWEVER...WINDS WILL GENERALLY BE NEAR OR
   BELOW 20 MPH IN THESE AREAS KEEPING FIRE WEATHER THREAT BELOW
   CRITICAL LEVELS THIS PERIOD.

   ...CRITICAL FIRE WEATHER AREA FOR MUCH OF AZ AND NM...
     
   ...SYNOPSIS... 
   DURING THE DAY 2 PERIOD...AN UPPER TROUGH NEAR THE SRN CA COAST AT
   18/12Z WILL MOVE INLAND ACROSS THE DESERT SW THROUGH EARLY MONDAY
   MORNING. AN ASSOCIATED 500MB JET WITH WINDS OF 45-50KT WILL
   TRANSLATE ACROSS SRN CA INTO AZ DURING SUNDAY AFTERNOON. 
     
   ...CRITICAL FIRE WEATHER AREA 1 - AZ AND NM...
     
   PRIMARY CONDITIONS: MODERATE WINDS / VERY LOW RH VALUES / MODERATE
   TO SEVERE DROUGHT CONDITIONS
   
   WLY WINDS OF 15-30 MPH ARE EXPECTED TO DEVELOP BY AFTERNOON ACROSS
   MUCH OF AZ/NM. MINIMUM RH VALUES WILL RANGE FROM 5-10 PERCENT
   ACROSS SERN AZ AND MUCH OF CENTRAL/SRN NM. ELSEWHERE ACROSS THE
   CRITICAL FIRE WEATHER AREA...MINIMUM RH VALUES WILL LIKELY RANGE
   FROM 10-15 PERCENT. VERY WARM TO HOT TEMPERATURES...WITH HIGHS IN
   THE LOW 90S TO 102 ACROSS SRN NM/SRN AZ...AND IN THE MID 80S TO LOW
   90S AT LOW ELEVATIONS ELSEWHERE...WILL CONTRIBUTE TO FIRE WEATHER
   THREAT. MODERATE TO SEVERE LONG-TERM DROUGHT CONDITIONS IN ADDITION
   TO ANTICIPATED AMBIENT CONDITIONS SHOULD BRING A PERIOD OF CRITICAL
   FIRE WEATHER TO AZ/NM DURING MUCH OF SUNDAY AFTERNOON AND EVENING.
   LOW-LEVEL STABILIZATION SHOULD BRING A SIGNIFICANT DECREASE IN WIND
   AT LOW ELEVATIONS BY LATE EVENING...WITH GRADUAL RH RECOVERY DURING
