   VALID 061200Z - 071200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR THE SRN GREAT BASIN INTO THE FOUR
   CORNERS REGION...
   
   ...SYNOPSIS...
   BROAD UPPER LOW CENTERED ACROSS COASTAL WA/ORE PER WATER VAPOR
   IMAGERY WILL PROGRESS SLOWLY INLAND ACROSS THE NWRN CONUS THIS
   PERIOD. MODERATELY STRONG MID-LEVEL GRADIENT FLOW ON SRN PERIPHERY
   OF THIS SYSTEM WILL IMPACT AN AREA FROM CENTRAL CA ACROSS THE SRN
   GREAT BASIN INTO THE FOUR CORNERS REGION. WINDS AT 500MB WILL RANGE
   FROM 45-55KT WITHIN THIS AXIS. SLOW PROGRESSION OF UPPER TROUGH WILL
   ALLOW 700MB THERMAL RIDGE TO STRENGTHEN AND BUILD NWD FROM CENTRAL
   NM INTO ERN WY. AT THE SURFACE...FRONTAL ZONE WILL EXIST COINCIDENT
   WITH STRONG BAROCLINIC ZONE ALOFT ASSOCIATED WITH UPPER TROUGH. BY
   EARLY EVENING...COLD FRONT WILL EXTEND FROM PARENT CYCLONE OVER SERN
   MT SWWD ACROSS FAR NWRN CO...ACROSS CENTRAL UT...AND INTO S-CENTRAL
   NV. FIRE WEATHER CONCERNS WILL BE FOCUSED SOUTH OF THIS FRONT.
   
   ...CRITICAL FIRE WEATHER AREA 1 - SERN CA...SRN NV...NRN AZ...SRN
   UT...SWRN/WRN CO...AND WRN/NWRN NM...
   
   PRIMARY CONDITIONS: MODERATE SURFACE WINDS / VERY LOW RH VALUES /
   AREAS OF DRY FUELS
   
   GENERATION OF STEEP LOW-LEVEL LAPSE RATES WITH DAYTIME HEATING/FULL
   SUNSHINE WILL ENHANCE VERTICAL MOMENTUM TRANSFER DURING THE
   AFTERNOON AND EARLY EVENING HOURS TODAY. BENEATH BELT OF STRONG
   MID-LEVEL FLOW...SURFACE WINDS WILL INCREASE TO 20-30 MPH DURING THE
   PEAK HEATING HOURS FROM SERN CA EWD ACROSS THE CRITICAL FIRE WEATHER
   AREA. WLY/SWLY LOW-LEVEL TRAJECTORIES WILL MAINTAIN LOW TO VERY LOW
   RH VALUES WITH MINIMUMS RANGING FROM 10-15 PERCENT. THE LOWEST
   READINGS ARE LIKELY AT LOWER ELEVATIONS...WHERE TEMPERATURES WILL
   REACH THE MID TO UPPER 80S. ABSENCE OF PRECIPITATION ACROSS MUCH OF
   THE REGION DURING THE PAST 7 DAYS HAS RESULTED IN DRYING FUELS
   SUPPORTIVE OF A CRITICAL FIRE WEATHER THREAT GIVEN THE EXPECTED
   AMBIENT CONDITIONS THIS AFTERNOON AND EVENING.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0241 AM CDT MON JUN 06 2005
   
   VALID 071200Z - 081200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR THE FOUR CORNERS AREA...
   
   ...SYNOPSIS...
   MAINTENENCE OF STRONG MID-LEVEL FLOW WILL OCCUR ON DAY 2 AS BROAD
   UPPER LOW REMAINS IN PLACE ACROSS THE NWRN CONUS. EMBEDDED SHORTWAVE
   TROUGH ON SRN PERIPHERY OF THIS FEATURE IS EXPECTED TO TRANSLATE
   ACROSS THE ERN GREAT BASIN INTO THE CENTRAL ROCKIES REGION DURING
   THE PEAK HEATING HOURS TUESDAY. THIS FEATURE WILL BE ACCOMPANIED BY
   40-50KT WINDS AT 500MB ACROSS ERN UT/WRN CO. LITTLE CHANGE IN
   LARGE-SCALE TROUGH POSITION WILL PERMIT 700MB THERMAL RIDGE AXIS TO
   REMAIN ACROSS THE SRN ROCKIES REGION NWD INTO THE CENTRAL HIGH
   PLAINS TUESDAY AFTERNOON AND EVENING. COMBINATION OF WINDY/WARM
   CONDITIONS AND LOW DAYTIME RH APPEARS TO FOCUS NEAR THE FOUR CORNERS
   REGION PER OPERATIONAL NAM/GFS AND NCEP SHORT-RANGE ENSEMBLE...ALONG
   AND SOUTH OF COLD FRONT THAT SHOULD EXTEND ACROSS THE CENTRAL
   ROCKIES FROM NWRN CO INTO S-CENTRAL UT TUESDAY AFTERNOON.
   
   ...CRITICAL FIRE WEATHER AREA 1 - SERN UT...WRN/SWRN CO...NRN/NERN
   AZ...AND NWRN/NRN NM...
   
   PRIMARY CONDITIONS: MODERATELY STRONG DAYTIME WINDS / LOW TO VERY
   LOW RH VALUES / AREAS OF DRY FUELS
   
   REDEVELOPMENT OF MODERATELY STRONG DAYTIME WINDS WILL OCCUR BY EARLY
   AFTERNOON TUESDAY AS BELT OF ENHANCED MID-LEVEL FLOW REMAINS ACROSS
   THE CRITICAL FIRE WEATHER AREA. DOWNWARD TRANSPORT OF MOMENTUM
   ASSOCIATED WITH DEEP SURFACE-BASED MIXING WILL RESULT IN WIDESPREAD
   SWLY WINDS OF 20-30 MPH AND RH MINIMUMS OF 10-15 PERCENT. HIGH
   TEMPERATURES WILL REACH THE MID/UPPER 80S ACROSS VALLEY AND BASIN
   AREAS OF THE FOUR CORNERS REGION. WINDS SHOULD GRADUALLY SUBSIDE AS
   BOUNDARY LAYER STABILIZES AFTER SUNSET...WITH LOCALIZED CONTINUATION
   OF STRONG WINDS ALONG RIDGES...PARTICULARLY ACROSS ERN/SERN UT AND
   WRN/SWRN CO WHERE STRONGEST GRADIENT FLOW PERSISTS THROUGH WEDNESDAY
   MORNING.
