   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0341 AM CST SAT NOV 04 2006
   
   VALID 041200Z - 051200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER SYSTEM WILL MOVE FROM THE GREAT BASIN INTO THE SRN PLAINS.
   IN THE WAKE OF THIS SYSTEM...SFC HIGH PRESSURE WILL BUILD SLOWLY
   WHILE MOVING INTO THE GREAT BASIN. OFFSHORE WINDS AND VERY LOW RH
   READINGS WILL DEVELOP OVER SRN/CENTRAL CA IN RESPONSE TO THE
   OFFSHORE FLOW...BUT WINDS SHOULD REMAIN WEAK ENOUGH THAT A CRITICAL
   FIRE WEATHER THREAT IS NOT EXPECTED ATTM. ELSEWHERE ACROSS THE
   NATION...A LARGE AREA OF SFC HIGH PRESSURE CENTERED OVER THE
   MID-ATLANTIC WILL PRODUCE COOL/DRY CONDITIONS OVER THE SERN PORTION
   OF THE NATION. LACK OF STRONG WINDS WILL PRECLUDE CRITICAL FIRE
   WEATHER CONDITIONS IN THIS AREA AS WELL.
   
   ...SRN CA...
   BEHIND A SHORTWAVE TROUGH...SFC HIGH PRESSURE OVER CENTRAL CA WILL
   BUILD EWD INTO THE GREAT BASIN. ALTHOUGH AN OFFSHORE GRADIENT WILL
   DEVELOP...IT WILL NOT BE APPRECIABLY STRONG /-7MB GRADIENT BETWEEN
   TPH AND LAX/ AND THUS SUSTAINED WINDS SHOULD REMAIN GENERALLY BELOW
   20 MPH. HOWEVER...VERY LOW RH READINGS WILL DEVELOP /AROUND 10
   PERCENT/ IN HIGHER ELEVATIONS AS A RESULT OF THE OFFSHORE FLOW.
   
   ...SERN STATES...
   ON THE SRN PORTION OF A LARGE AREA OF SFC HIGH PRESSURE AREA
   CENTERED OVER THE MID-ATLANTIC...DRY NELY FLOW WILL PREVAIL. DESPITE
   LOW RH READINGS /FROM 20-25 PERCENT/...RELATIVELY COOL TEMPERATURES
   IN THE UPPER 50S TO MID 60S COMBINED WITH SUSTAINED WINDS FROM 5-10
   MPH WILL PRECLUDE A CRITICAL FIRE WEATHER THREAT.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0342 AM CST SAT NOV 04 2006
   
   VALID 051200Z - 061200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   ANOTHER UPPER TROUGH WILL MOVE FROM THE WEST COAST INTO THE PLAINS
   THROUGH THE PERIOD. IN ADVANCE OF THIS SYSTEM...SCT PRECIPITATION IS
   EXPECTED TO DEVELOP OVER THE SRN PLAINS. IN THE WAKE OF THE UPPER
   TROUGH...SFC HIGH PRESSURE WILL BUILD SLIGHTLY OVER THE GREAT BASIN.
   CRITICAL FIRE WEATHER CONDITIONS ARE POSSIBLE OVER THE MTNS/PASSES
   OF THE SRN CA COASTAL RANGE AS A RESULT OF INCREASING OFFSHORE
   WINDS. ELSEWHERE...A BROAD AREA OF HIGH PRESSURE OVER THE
   MID-ATLANTIC WILL SUPPORT ANOTHER DAY OF DRY CONDITIONS TO THE
   SE...BUT CRITICAL FIRE CONDITIONS ARE AGAIN NOT EXPECTED.
   
   ...SRN CA...
   ANOTHER UPPER TROUGH...ABOUT 1000 MILES OFF THE CA COAST EARLY THIS
   MORNING...WILL MOVE STEADILY EWD THROUGH THE PERIOD REACHING THE
   PLAINS BY 06/12Z. IN THE WAKE OF THIS TROUGH...SFC HIGH PRESSURE
   OVER THE GREAT BASIN SHOULD STRENGTHEN SOME. THERE REMAINS SOME
   INCONSISTENCIES IN THE FCST MODELS REGARDING THE AMT OF BUILDING IN
   THE SFC HIGH PRESSURE AND RESULTANT AMT OF INCREASE IN THE OFFSHORE
   PRESSURE GRADIENT. ATTM...OFFSHORE WINDS ARE NOT ANTICIPATED TO
   EXCEED 20 MPH WITH GUSTS OVER 30 MPH. DESPITE THE UNCERTAINTY IN THE
   WIND FCSTS...VERY LOW RH READINGS /FROM 6-12 PERCENT/ ARE EXPECTED
   IN MOST OF THE INTERIOR VALLEYS AND MTNS. AREA WILL BE MONITORED FOR
   A POSSIBLE CRITICAL AREA IN TOMORROW/S OUTLOOK.
   
   ...SERN STATES...
   SFC HIGH PRESSURE OVER THE MID-ATLANTIC WILL CONTINUE A DRY NELY LOW
   LEVEL FLOW ACROSS THE REGION. DESPITE LOW RH READINGS FROM 20-30
   PERCENT...SUSTAINED WINDS SHOULD REMAIN LESS THAN 15 MPH.
