   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0240 AM CDT SAT SEP 20 2008
   
   VALID 201200Z - 211200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A CLOSED UPPER LOW WILL BECOME AN OPEN UPPER TROUGH AND MOVE NEWD
   FROM PARTS OF THE NRN GREAT BASIN INTO THE NRN ROCKIES REGION. 
   MODEST SWLY/S WILL OVERSPREAD PARTS OF THE SRN/ERN GREAT BASIN AND
   LEAD TO NEAR CRITICAL FIRE WEATHER CONDITIONS.  AS THE SYSTEM MOVES
   NEWD...SUFFICIENT INSTABILITY WILL COMBINE WITH MID-LEVEL MOISTURE
   TO PROMOTE INITIALLY ISOLATED-SCATTERED DRY TSTMS OVER PARTS OF THE
   NRN ROCKIES.  SURFACE LOW PRESSURE WILL DEVELOP LEADING TO A
   STRENGTHENING PRESSURE GRADIENT OVER PARTS OF THE NRN HIGH PLAINS. 
   UNSEASONABLY WARM TEMPS APPROACHING 90 DEG F AND LOW RH IN THE TEENS
   WILL RESULT IN NEAR CRITICAL CONDITIONS OVER THE AFOREMENTIONED
   AREA.  ELSEWHERE ACROSS THE CONUS...SFC HIGH PRESSURE WILL CONTINUE
   TO DOMINATE THE WEATHER EAST OF THE ROCKIES WITH GENERALLY LIGHT
   WINDS AND LOW RH READINGS.
   
   ...SRN NV/WRN UT...
   MODEST SWLY WINDS AT THE MID LEVELS AND STEEP LOW-MID LEVEL LAPSE
   RATES WILL SUPPORT SWLY WINDS FROM 15-25 MPH AHEAD OF A SHORTWAVE
   TROUGH MOVING THROUGH THE GREAT BASIN.  SEASONABLY LOW RH READINGS
   FROM 15-20 PERCENT AND MARGINAL WIND SPEEDS WILL LIKELY PRECLUDE A
   CRITICAL FIRE WEATHER THREAT. 
   
   ...ERN ID-CENTRAL/ERN MT...
   GREAT BASIN 00Z/20 RAOBS SAMPLED AN ENVIRONMENT SUPPORTING SOME DRY
   TSTMS.  AS THE UPPER SYSTEM MOVES TOWARDS THE REGION...TSTMS ARE
   EXPECTED TO DEVELOP OVER WRN MT/ERN ID DURING THE AFTERNOON. 
   FURTHER EAST...A LEE SURFACE TROUGH OVER WRN/CENTRAL MT WILL SUPPORT
   SE WINDS 15-20 MPH WITH HIGHER GUSTS.  DESPITE WARM TEMPS AND SPARSE
   LOW LEVEL MOISTURE YIELDING LOW RH...EXPECTED SHORT DURATION OF
   STRONG SUSTAINED WINDS /AOA 20 MPH/ WILL ACT TO LESSEN THE OVERALL
   THREAT.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0353 AM CDT SAT SEP 20 2008
   
   VALID 211200Z - 221200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER TROUGH OVER THE NRN HIGH PLAINS AT THE START OF THE PERIOD
   WILL MOVE INTO THE SRN PARTS OF THE CANADIAN PRAIRIE PROVINCES. 
   AHEAD OF THIS SYSTEM...STRONG SSELY WINDS WILL DEVELOP IN RESPONSE
   TO A LEE SURFACE TROUGH.  AS A RESULT...MARGINALLY SUPPORTIVE FIRE
   WEATHER CONDITIONS MAY OCCUR ACROSS PARTS OF THE NRN PLAINS.  THE
   SURFACE TROUGH WILL EXTEND S OVER PARTS OF THE CENTRAL HIGH PLAINS. 
   MIN RH IN THE TEENS APPEARS POSSIBLE IN LOCALIZED AREAS WITH GUSTY
   /ALBEIT WEAKER SUSTAINED/ SSWLY WINDS.  UPSTREAM OF THE
   AFOREMENTIONED UPPER SYSTEM...ANOTHER IMPULSE WILL MOVE ONSHORE THE
   CENTRAL PACIFIC COAST LEADING TO STRENGTHENING MID-LEVEL WINDS OVER
   PARTS OF THE WRN GREAT BASIN.
   
   ...NRN/CENTRAL HIGH PLAINS...
   MODERATELY STRONG SUSTAINED WINDS 15-25 MPH WITH HIGHER GUSTS SEEM
   LIKELY ACROSS A PART OF THE NRN PLAINS.  LOCATIONS IMMEDIATELY W AND
   ALONG THE VICINITY OF COLD FRONT/SURFACE TROUGH MAY EXPERIENCE THE
   LONGEST DURATION OF MARGINAL FIRE WEATHER SUPPORTIVE CONDITIONS
   /WINDS AND MARGINALLY LOW RH/.  FURTHER S OVER THE CENTRAL HIGH
   PLAINS...A RELATIVELY WEAKER PRESSURE GRADIENT /SSWLY/S ONLY 10-20
   MPH/ APPEARS TO LESSEN POTENTIAL FOR CRITICAL FIRE WEATHER
   CONDITIONS.
