   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   UPPER LOW CENTERED OVER CENTRAL CO EARLY THIS MORNING IS EXPECTED TO
   SHIFT ENEWD INTO THE CENTRAL PLAINS BY THIS EVENING. A BROAD
   MID-LEVEL THERMAL TROUGH REMAINS ACROSS MUCH OF THE CENTRAL/NRN
   INTERMOUNTAIN WEST...WITH A BELT OF MODERATE WLY MID-LEVEL FLOW
   /30-35KT AT 500MB/ ACROSS SERN AZ EWD ACROSS SRN NM. SURFACE LOW
   PRESSURE INTENSIFIES ACROSS CENTRAL NEB THIS AFTERNOON AS UPPER
   TROUGH EMERGES EAST OF THE FRONT RANGE. A DRYLINE WILL DEVELOP
   ACROSS WRN OK SWD ACROSS W-CENTRAL TX...WITH HOT TEMPERATURES AND
   LOW RH VALUES ACROSS MUCH OF THE SRN HIGH PLAINS REGION.
   ADDITIONALLY...A COLD FRONT TRAILING SWWD FROM THE SURFACE LOW WILL
   MOVE SWD THROUGH SWRN KS...THE OK PANHANDLE...AND FAR NERN NM DURING
   THE AFTERNOON AND EARLY EVENING HOURS. PRIMARY FIRE WEATHER FOCUS
   THIS PERIOD IS SOUTH OF THIS COLD FRONT AND WEST OF THE
   DRYLINE...PARTICULARLY WWD ACROSS THE MTNS OF CENTRAL/WRN NM WHERE
   PRECIPITATION HAS BEEN LIGHT DURING THE PAST WEEK.
   
   ...SRN ROCKIES...
   
   WLY WINDS WILL INCREASE TO 15-20 MPH BY EARLY AFTERNOON ACROSS MUCH
   OF NM...SWRN TX...AND SERN AZ...AND PERSIST THROUGH THE EARLY
   EVENING HOURS. THESE WINDS WILL DEVELOP IN RESPONSE TO RELATIVELY
   DEEP VERTICAL MIXING /6-7 KFT AGL/ BENEATH MODERATE MID-LEVEL WLY
   FLOW AND STRONG INSOLATION WITH MOSTLY SUNNY SKIES. CONTINUATION OF
   LOW MINIMUM RH VALUES /GENERALLY AROUND 15 PERCENT/ ARE ALSO
   EXPECTED. 
   
   WITH UPPER LOW SHIFTING EWD OUT OF THE CENTRAL ROCKIES AREA...BAND
   OF MID-LEVEL FLOW WILL ACTUALLY BE SOMEWHAT WEAKER ACROSS THE
   SOUTHWESTERN U.S. TODAY AS COMPARED TO YESTERDAY...WITH A
   CORRESPONDING 5-10 MPH DROP IN SURFACE WINDS COMPARED TO FRIDAY
   AFTERNOON. DRY FUELS...SEASONABLE TEMPERATURES...AND LOW RH VALUES
   ARE FAVORABLE FOR WILDFIRE...HOWEVER...MARGINAL WIND SPEEDS WILL
   PRECLUDE ISSUANCE OF A CRITICAL FIRE WEATHER AREA.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0353 AM CDT SAT JUN 04 2005
   
   VALID 051200Z - 061200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE SOUTHERN GREAT
   BASIN AND SURROUNDING AREAS...
   
   ...SYNOPSIS...
   DURING THE DAY 2 PERIOD...NAM AND GFS ARE CONSISTENT IN DIGGING A
   LARGE AND COLD 500MB TROUGH SEWD INTO THE NWRN CONUS. MID-LEVEL FLOW
   OF 45-55KT WILL TRANSLATE INTO THE WRN GREAT BASIN DURING SUNDAY
   AFTERNOON...ON THE SRN PERIPHERY OF THE UPPER SYSTEM. ATTENDANT
   SURFACE COLD FRONT IS EXPECTED TO STRETCH FROM WRN MT SWWD ACROSS
   S-CENTRAL ID INTO CENTRAL NV DURING THE LATE AFTERNOON/EARLY EVENING
   HOURS. CONTINUED LOW SURFACE RH VALUES AND EXPECTED INCREASE IN
   SURFACE WINDS SUGGEST THAT CRITICAL FIRE WEATHER CONDITIONS ARE
   LIKELY DURING MOST OF SUNDAY AFTERNOON INTO SUNDAY EVENING ACROSS
   THE SRN GREAT BASIN.
   
   ...CRITICAL FIRE WEATHER AREA 1 - CENTRAL/SRN NV...SWRN UT...NWRN
   AZ...SERN CA...
   
   PRIMARY CONDITIONS: INCREASING WINDS / LOW RH VALUES / DRY FUELS
   
   SURFACE WINDS WILL GRADUALLY INCREASE FROM THE SW DURING THE
   AFTERNOON HOURS...REACHING 20-30 MPH ACROSS MOST OF CENTRAL/SRN NV
   AND SERN CA BY 04/21Z. SURFACE WINDS OF 15-25 MPH ARE LIKELY ACROSS
   SERN UT AND NWRN AZ. RH VALUES OF 10-15 PERCENT WILL ACCOMPANY THE
   MODERATE AFTERNOON WINDS ALONG A SW-NE AXIS JUST EAST OF THE COLD
   FRONT...CONTRIBUTING TO CRITICAL FIRE WEATHER POTENTIAL.
