   ...CRITICAL FIRE WEATHER AREA FOR PARTS OF WRN ND...
   
   ...SYNOPSIS...
   A SEASONABLY STRONG SHORTWAVE TROUGH AND UPPER LEVEL SPEED MAX
   ACCORDING TO 00Z/08 NRN ROCKIES RAOBS...WILL CONTINUE TO MOVE E
   ACROSS PARTS OF THE NRN CONUS.  AN UPPER TROUGH OVER THE MS VALLEY
   AT THE START OF THE PERIOD WILL DEAMPLIFY AND BECOME MORE
   PROGRESSIVE OVER THE GRT LKS REGION.  FURTHER S...AN UPPER
   DISTURBANCE ON THE TRAILING SRN END OF THE MID-LEVEL TROUGH WILL
   BECOME A CLOSED LOW AND MEANDER ESEWD OVER THE ERN GULF COAST
   STATES.  AT THE SURFACE...A COLD FRONT WILL MOVE ACROSS A LARGE PART
   OF THE MIDWEST STATES AND BEHIND IT STRONG GUSTY SURFACE WINDS WILL
   DEVELOP ACROSS THE NRN PLAINS.  AT THE END OF THE PERIOD...STRONG
   850MB WINDS ALONG AND W OF THE NRN CA COAST MAY OCCUR...BUT LACK OF
   A SIGNIFICANT OFFSHORE TRAJECTORY WILL LIKELY MAINTAIN NON-CRITICAL
   RH.
   
   ...CRITICAL FIRE WEATHER AREA - PARTS OF WRN ND...
   
   PRIMARY CONDITIONS: STRONG WINDS / LOW RH
   
   ...WRN ND...
   AS THE UPPER TROUGH GLANCES THE REGION TO THE N...A SURFACE LOW IS
   FORECAST TO MOVE E ACROSS THE SRN PARTS OF THE CANADIAN PRAIRIE
   PROVINCES.  A STRONG SURFACE PRESSURE GRADIENT WILL DEVELOP BEHIND A
   COLD FRONT WHICH WILL MOVE THROUGH DURING THE EARLY MORNING HOURS ON
   WEDNESDAY.  LOW LEVEL LAPSE RATES SHOULD STEEPEN SUFFICIENTLY TO
   ENABLE SOME DOWNWARD MIXING OF HIGHER MOMENTUM ALOFT TO THE SURFACE.
    DETERMINISTIC GUIDANCE WAS NOTICEABLY WEAKER IN 850MB FLOW FIELDS
   COMPARED TO EARLY MORNING GGW VWP AT 850MB /85 MPH/.  THIS SUGGESTS
   WINDS MAY BE STRONGER THAN PROGGED BY DETERMINISTIC OUTPUT. 
   SUSTAINED WINDS OF 25-35 MPH APPEAR PROBABLE WITH HIGHER GUSTS
   LIKELY.  DESPITE HIGH TEMPS ONLY EXPECTED TO REACH INTO THE UPPER
   50S TO LOWER 60S--SERVING AS A LIMITING FACTOR--MIN RH IS EXPECTED
   TO BE NEAR 20 PERCENT WARRANTING A CRITICAL DESIGNATION.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0427 AM CDT WED OCT 08 2008
   
   VALID 091200Z - 101200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN AMPLIFYING UPPER PATTERN APPEARS LIKELY AS A LONGWAVE TROUGH
   DEVELOPS OVER THE WRN CONUS WITH A BUILDING UPPER RIDGE OVER THE ERN
   CONUS.  STRENGTHENING FLOW FIELDS AHEAD OF WRN CONUS TROUGH AND
   MARGINALLY LOW RH MAY OCCUR OVER PARTS OF THE SRN GREAT BASIN.  AT
   THE SURFACE...A FRONTAL BOUNDARY APPEARS TO ELONGATE FROM W TO E
   FROM PARTS OF THE GREAT BASIN EWD TO THE MID-ATLANTIC.  SURFACE
   CYCLOGENESIS AND LEE TROUGHING OVER THE CENTRAL HIGH PLAINS WILL
   LIKELY LEAD TO GUSTY WINDS ACROSS THE AFOREMENTIONED REGION.
   
   ...PARTS OF SRN UT/NRN AZ...
   INCREASING SWLY MID-LEVEL FLOW /30-40 MPH AT 700MB/ APPEARS LIKELY
   AHEAD OF DIGGING UPPER TROUGH OVER THE WEST.  MODEL FORECAST
   SOUNDINGS INDICATE MIN RH MAY FALL INTO THE LOWER TO MID TEENS LATE
   THURSDAY AFTERNOON AS LOW LEVEL FLOW BEGINS TO STRENGTHEN. 
   ATTM...MODEL CONSENSUS SUGGESTS SUSTAINED SURFACE WINDS MAY APPROACH
   25 MPH.  HOWEVER...ANY APPRECIABLE FIRE WEATHER THREAT WILL LIKELY
   BE HINDERED BY MARGINALLY LOW RH CONDITIONS/FUELS--PRECLUDING A
   CRITICAL AREA.
