   VALID 031200Z - 041200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER TROUGH WILL WEAKEN AS IT LIFTS NEWD THROUGH THE GREAT
   LAKES/OHIO VALLEY.  IN THE WAKE OF THIS TROUGH...A ZONAL PATTERN
   WILL SETUP ACROSS THE PLAINS/ROCKIES WITH SURFACE HIGH PRESSURE
   BEING THE PRIMARY WEATHER FEATURE.  MEANWHILE...THE NEXT UPPER
   TROUGH WILL DIG SWD ALONG THE WEST COAST.
   
   ...SRN GREAT BASIN...
   
   MID-LEVEL WINDS WILL LIKELY INCREASE OVER THE AREA IN RESPONSE TO
   THE UPPER TROUGH MOVING TOWARDS THE REGION.  SWLY BOUNDARY LAYER
   WINDS WILL GRADUALLY INCREASE DURING THE AFTERNOON HOURS IN RESPONSE
   TO THIS FEATURE.  THE LATEST FORECAST SOUNDINGS CONTINUE TO SUGGEST
   THAT THE HIGHER MOMENTUM FLOW WILL STAY ALOFT ABOVE THE BOUNDARY
   LAYER.  AS A RESULT...SUSTAINED WINDS SHOULD REMAIN BELOW 20 MPH
   PRECLUDING A CRITICAL FIRE WEATHER THREAT.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0405 AM CDT SAT MAY 03 2008
   
   VALID 041200Z - 051200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A ZONAL FLOW REGIME WILL INFLUENCE MUCH OF THE ERN TWO THIRDS OF THE
   CONUS OUTSIDE OF THE WEAKENING UPPER LOW OVER ONTARIO.  A SURFACE
   PRESSURE TROUGH WILL LIKELY FORM OVER THE S CENTRAL HIGH PLAINS. 
   FURTHER WEST...AN UPPER TROUGH WILL CONTINUE SWD ALONG THE W COAST
   WITH STRENGTHENING SWLY FLOW AHEAD OF THIS SYSTEM.  AN AREA OF
   SURFACE LOW PRESSURE MAY FORM IN THE VICINITY OF THE SRN GREAT
   BASIN/LOWER CO RIVER VALLEY.
   
   ...LOWER CO RIVER VALLEY/SRN GREAT BASIN...
   
   S-SWLY FLOW AHEAD OF THE NEXT SYSTEM WILL LIKELY STRENGTHEN ON
   SUNDAY /DAY 2/.  ANTECEDENT LOW RH WILL REMAIN FIXED IN THE REGION. 
   ONE COMPLICATING FACTOR IS MODEL DISAGREEMENT ON THE EVOLUTION OF
   THIS SYSTEM.  AS A RESULT...SOME UNCERTAINTY EXISTS ON THE PLACEMENT
   AND STRENGTH OF THE MID-LEVEL WIND FIELD.  FORECAST SOUNDINGS
   SUGGEST SOME POTENTIAL FOR CRITICAL CRITERIA BEING MET. 
   HOWEVER...GIVEN UNCERTAINTY REGARDING STRENGTH OF THE LOW TO
   MID-LEVEL FLOW...WILL HIGHLIGHT AS A SEE TEXT AREA ATTM. 
   
   ...S CENTRAL HIGH PLAINS...
   
   LEE TROUGHING WILL LIKELY DEVELOP RESULTING IN A STRENGTHENING
   PRESSURE GRADIENT ACROSS THE SOUTH CENTRAL HIGH PLAINS.  SUSTAINED
   SWLY WINDS MAY APPROACH 20 MPH.  WITH MOSTLY SUNNY SKIES PROMOTING
   AFTERNOON HIGHS IN THE 70S TO NEAR 80 DEG...IT APPEARS THAT MIN RH
   WILL BE IN THE TEENS AND SINGLE DIGITS.  ATTM...ANTICIPATING
   BORDERLINE WIND CRITERIA WHICH WILL PRECLUDE A CRITICAL DELINEATION.
