   ...SYNOPSIS...
   AN UPPER LEVEL CLOSED LOW EVIDENT IN EARLY MORNING SATELLITE IMAGERY
   WILL MEANDER SEWD OVER THE PACIFIC NW.  A PERSISTENT MID-LEVEL
   ANTICYCLONE CENTERED OVER THE DESERT SW WILL INFLUENCE THE SWRN
   QUARTER OF THE CONUS...MAINTAINING VERY HOT AND DRY CONDITIONS
   ACROSS THIS REGION.  INCREASING BOUNDARY LAYER SWLY/S WILL DEVELOP
   TOWARDS THE EARLY EVENING HOURS OVER PARTS OF THE SRN GREAT BASIN AS
   THE PRESSURE GRADIENT BETWEEN THE TWO AFOREMENTIONED SYSTEMS BEGINS
   TO INTENSIFY.
   
   ...PARTS OF SRN CA...
   VERY HOT AFTERNOON HIGH TEMPS IN THE 100-110 DEG F RANGE WILL AGAIN
   BE COMMON OVER THE REGION TODAY UNDERNEATH HIGH PRESSURE.  WITH AN
   ANTECEDENTLY DRY AIRMASS IN PLACE...RH VALUES ARE AGAIN EXPECTED TO
   BE WELL INTO THE SINGLE DIGITS.  ASIDE FROM GUSTY SWLY WINDS /20-30
   MPH/ THAT MAY OCCUR IN LOCALIZED AREAS...MORE WIDESPREAD TEMPERED
   GUSTS /10-20 MPH/ AND GENERALLY WEAK SUSTAINED WINDS WILL ACT TO

   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF CNTRL-SRN UT / ERN-SRN
   NV / NWRN AZ...
   
   ...SYNOPSIS...
   UPPER LOW OVER THE PACIFIC NW WILL SLOWLY MOVE ESEWD INTO THE NRN
   ROCKIES AS A MID-UPPER ANTICYCLONE REMAINS ENTRENCHED ACROSS THE
   DESERT SW.  AN ATTENDANT QUASI-STATIONARY FRONT WILL BE DRAPED W TO
   E ACROSS THE NRN GREAT BASIN.  S OF THE BOUNDARY VERY WARM AND
   HOT/DRY CONDITIONS WILL PREVAIL.  AS THE UPPER LOW GLANCES THE GREAT
   BASIN REGION...AN INCREASING LOW-MID LEVEL HEIGHT GRADIENT WILL
   RESULT IN STRONG SWLY WINDS LEADING TO CRITICAL CONDITIONS OVER PART
   OF THE CNTRL AND SRN GREAT BASIN.  SOME SLIGHT IMPROVEMENT IN RH
   APPEARS POSSIBLE OVER PORTIONS OF ADJACENT COASTAL AREAS OF SRN CA
   WITH AN INCREASING MARINE INFLUENCE.
   
   ...CRITICAL FIRE WEATHER AREA - PORTIONS OF CNTRL-SRN UT / ERN-SRN
   NV / NWRN AZ...
   
   PRIMARY CONDITIONS: LOW RH / STRONG WINDS / RECEPTIVE FUELS
   
   STRONG SWLY SUSTAINED WINDS /20-25 MPH/ WILL LIKELY DEVELOP AS THE
   BOUNDARY LAYER WARMS INDUCING DEEP BOUNDARY LAYER MIXING.  WITH WARM
   TO HOT TEMPS EXPECTED RANGING FROM THE 80S TO NEAR 110 ACROSS THE
   AREA...RH IS EXPECTED TO BE CORRESPONDINGLY LOW.  MODEL FORECAST
   SOUNDINGS GENERALLY PROGNOSTICATE RH FALLING INTO THE SINGLE DIGITS
   OVER THE SRN PORTIONS OF THE HIGHLIGHTED AREA TO LOWER TEENS IN THE
   N.
