   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0141 AM CST MON NOV 21 2005
   
   VALID 211200Z - 221200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER LOW WILL MOVE TOWARDS THE CA COAST THROUGH THE
   PERIOD...WHILE THE PERSISTENT AND STRONG UPPER RIDGE OVER THE WEST
   WILL SLOWLY SHIFT IT/S AXIS EWD ACROSS THE GREAT BASIN/PAC NW. THE
   RESULT WILL BE A DECREASE IN THE OFFSHORE WIND SPEEDS OVER MUCH OF
   CA. LOW RH READINGS WILL STILL BE PRESENT...LEADING TO EXTREMELY
   HIGH FIRE DANGERS OVER MUCH OF THE REGION. DRY NWLY FLOW WILL BE
   PRESENT OVER THE PLAINS STATES. OVER THE SRN PLAINS...MILD
   TEMPERATURES IN THE 60S AND 70S WILL LEAD TO AN INCREASE IN FIRE
   DANGER...ALBEIT MITIGATED BY THE LACK OF MODERATE OR STRONG WINDS.
   MEANWHILE...A BROAD UPPER TROUGH WILL RESIDE OVER THE EASTERN THIRD
   OF THE NATION...WHERE BELOW NORMAL TEMPERATURES AND HIGH RH READINGS
   WILL EXIST.
   
   ...SRN CA...
   OFFSHORE WINDS WILL AVERAGE FROM 15-20 MPH EARLY THIS MORNING...AS A
   MODERATE PRESSURE GRADIENT REMAINS IN PLACE PER RECENT SURFACE
   ANALYSIS. APPROACHING UPPER TROUGH AND DIURNAL EFFECTS SHOULD AID IN
   WEAKENING THE OFFSHORE GRADIENTS AND ALLOW FOR CESSATION OF MODERATE
   OFFSHORE WINDS FOR THE REMAINDER OF THE DAY/OVERNIGHT. GIVEN LIMITED
   DURATION OF MARGINAL NEAR CRITICAL FIRE WEATHER CONDITIONS...NO
   OUTLOOK AREA WILL BE ISSUED. 
   
   ...SRN PLAINS...
   NWLY WINDS WILL AVERAGE FROM 10-15 MPH OVER MUCH OF THE SRN PLAINS
   THROUGH THE PERIOD...AS HIGH PRESSURE REMAINS OVER THE SRN/CENTRAL 
   ROCKIES...AND LOW PRESSURE RESIDES WELL EAST OF THE REGION.  A
   WARMING TREND WILL ENSUE AS DOWNSLOPE COMPONENT TO THE LOW LEVEL
   FLOW INCREASES. AFTERNOON HIGH TEMPERATURES ARE FCST TO BE ON
   AVERAGE 5 DEGREES ABOVE NORMAL. COMBINED WITH LOW DEWPTS...MIN RH
   READINGS FROM 20-30 PERCENT ARE EXPECTED DURING THE AFTERNOON. LACK
   OF STRONGER WINDS WILL PRECLUDE A CRITICAL FIRE WEATHER AREA.

Day 2 Fire Weather Forecast graphic

   ZCZC SPCFWDDY2 ALL
   FNUS22 KWNS 210741
   
   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0141 AM CST MON NOV 21 2005
   
   VALID 221200Z - 231200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   THE OVERALL UPPER AIR PATTERN FROM DAY ONE TO DAY TWO WILL CHANGE
   LITTLE ACROSS THE NATION. A BROAD UPPER TROUGH WILL REMAIN OVER THE
   ERN 1/3RD OF THE NATION...WHILE AN UPPER RIDGE WILL RESIDE OVER MOST
   OF THE WEST. AS ON DAY ONE...OFFSHORE FLOW WILL BE MITIGATED OVER CA
   AGAIN DUE TO PRESENCE OF AN UPPER LOW NEARBY. MEANWHILE...DRY NWLY
   FLOW WILL REMAIN OVER THE PLAINS STATES. DOWNSLOPE NATURE OF THE LOW
   LEVEL FLOW WILL CONTINUE TO AID IN WARM TEMPERATURES WITH READINGS 
   5-10 DEG ABOVE NORMAL. DESPITE LOW RH READINGS...LACK OF MODERATE OR
   HIGHER SURFACE WINDS WILL PRECLUDE ANY CRITICAL FIRE WEATHER THREAT
   OVER THIS REGION.
   
   ...SRN PLAINS EWD INTO THE LOWER MS VALLEY...
   AFTERNOON WNWLY WINDS FROM 5-15 MPH WILL BE COMMONPLACE OVER MOST OF
   THE SRN PLAINS EWD INTO THE LOWER MS VALLEY. DOWNSLOPE COMPONENT TO
   THE FLOW AND GRADUALLY WARMING LOW LEVELS WILL AID IN SFC
   TEMPERATURES IN THE UPPER 60S TO LOWER 80S. CONSEQUENT RH READINGS
   WILL AVERAGE FROM 20-30 PERCENT. GIVEN LACK OF STRONGER LOW LEVEL
   FLOW...OVERALL FIRE WEATHER THREAT WILL REMAIN BELOW CRITICAL
   LEVELS.
   
   ...SRN/CENTRAL CA...
   ONSHORE FLOW WILL GRADUALLY STRENGTHEN ALONG COASTAL AREAS OF
   SRN/CENTRAL CA. THE DEPTH OF THE MARINE LAYER IS FCST TO BE
   SUFFICIENTLY LOW THAT MTNS/INTERIOR VALLEYS WILL STILL SEE WARM
   TEMPERATURES/LOW RH READINGS FROM 10-15 PERCENT. LACK OF MODERATE
   WINDS WILL PRECLUDE ANY CRITICAL FIRE WEATHER THREAT.
