   ...SYNOPSIS...
   EXPANSIVE UPPER RIDGE OVER THE SWRN U.S. WILL REMAIN IN PLACE WITH
   UPPER DISTURBANCES TRAVERSING EWD ACROSS THE UPPER MIDWEST AND PARTS
   OF NEW ENGLAND.  NEUTRAL TO WEAK UPPER LEVEL RIDGING WILL OCCUR OVER
   PARTS OF THE NRN INTERMOUNTAIN WEST AHEAD OF A MORE SUBSTANTIAL
   DISTURBANCE MOVING ONSHORE THE BC/WASHINGTON COAST.  DESPITE STRONG
   UPPER FLOW REMAINING OVER PARTS OF THE NRN ROCKIES/INTERMOUNTAIN
   WEST AND MIN RH REACHING CRITICAL LEVELS DURING THE AFTERNOON
   HOURS...RELATIVELY WEAK LOW LEVEL WINDS WILL PRECLUDE THE
   DELINEATION OF A CRITICAL AREA.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0422 AM CDT THU JUL 31 2008
   
   VALID 011200Z - 021200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   ON THE PERIPHERY OF AN UPPER LEVEL RIDGE CENTERED OVER THE SRN
   ROCKIES...A LEAD UPPER SHORTWAVE TROUGH WILL MOVE NEWD OVER PARTS OF
   SRN BC/ALBERTA.  THE SRN PORTION OF THE ASSOCIATED MID-LEVEL SPEED
   MAX WILL OVERSPREAD PARTS OF THE NRN ROCKIES/NRN HIGH PLAINS.  AT
   THE SURFACE...A COLD FRONT WILL MOVE EWD OVER PARTS OF THE NRN
   INTERMOUNTAIN WEST AND HIGH PLAINS OF MONTANA DURING THE PERIOD WITH
   AN ASSOCIATED WIND SHIFT.  GUSTY WINDS AND LOW MIN RH APPEAR LIKELY
   ACROSS THE AFOREMENTIONED REGION.  FURTHER SOUTH AND EAST...A
   LEE-SIDE SURFACE PRESSURE TROUGH IS FORECAST TO DEVELOP AS FAR S AS
   THE CENTRAL HIGH PLAINS...LEADING TO AN INCREASING PRESSURE GRADIENT
   AND STRENGTHENING SLY WINDS.  HOT TEMPS/LOW RH AND GUSTY WINDS MAY
   INCREASE FIRE WEATHER CONCERNS OVER PARTS OF THE CENTRAL HIGH
   PLAINS.
   
   ...PARTS OF NRN MT...
   POTENTIAL EXISTS FOR STRONG SUSTAINED WLY WINDS /AROUND 20 MPH/ AND
   LOW MIN RH /UPPER TEENS/ AFTER COLD FRONTAL PASSAGE.  DETERMINISTIC
   PLAN VIEW MODEL GUIDANCE INDICATES SUFFICIENT LOW TO MID-LEVEL FLOW
   /25-35 KTS AT 700MB/ MAY OCCUR OVER THE AREA.  WITH WARM TEMPS AND
   STEEP LAPSE RATES...AMPLE BOUNDARY LAYER MIXING IS PROBABLE WHICH
   WOULD LEAD TO AT LEAST CRITICALLY LOW RH FOR SEVERAL HOURS.  DESPITE
   CONFIDENCE WITH ABOVE MENTIONED SCENARIO...UNCERTAINTY ASSOCIATED
   WITH DIFFERING MODEL OUTPUT WITHHOLDS A CRITICAL ISSUANCE AT THIS
   TIME WITH THE POSSIBILITY OF A CRITICAL DESIGNATION IN THE NEXT
   UPDATE. 
   
   ...PARTS OF THE NRN INTERMOUNTAIN WEST...
   WARM TEMPERATURES AND LOW RH SEEM LIKELY ACROSS A LARGE PART OF THE
   AREA.  WITH PRIMARY IMPULSE PASSING TO THE N OF THE REGION...FLOW
   FIELDS WILL PROBABLY BE WEAKER WITH SWD EXTENT.  STEEP LAPSE RATES
   MAY PROMOTE GUSTY WINDS BUT MODEST SUSTAINED SURFACE WIND SPEEDS
   ACCORDING TO THE LATEST MODEL GUIDANCE MAY LIMIT AN OTHERWISE
   GREATER FIRE WEATHER THREAT.
