   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0352 AM CST MON NOV 06 2006
   
   VALID 061200Z - 071200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER TROUGH OVER THE SRN PLAINS WILL MOVE SLOWLY EWD THROUGH
   TODAY. AHEAD OF THIS SYSTEM...SCT HVY PRECIPITATION WILL OCCUR OVER
   PORTIONS OF TX AND THE LOWER MS VALLEY. ELSEWHERE...UPPER RIDGING
   WILL REMAIN DOMINANT OVER MOST OF THE WEST. A MODEST OFFSHORE FLOW
   WILL EXIST OVER PORTIONS OF SRN CA TODAY. VERY LOW RH READINGS WILL
   CONTINUE AS A RESULT...BUT OVERALL SUSTAINED WIND SPEEDS ARE NOT
   EXPECTED TO BE SUFFICIENTLY STRONG TO WARRANT A CRITICAL OUTLOOK
   ISSUANCE. AS THE UPPER RIDGE BEGINS TO BREAKDOWN OVER THE NRN
   ROCKIES...STRONG WLY WINDS WILL RESULT. LACK OF LOWER RH READINGS IN
   THIS REGION WILL PRECLUDE CRITICAL FIRE WEATHER CONDITIONS.
   
   ...SRN CA...
   A 6-7 MB PRESSURE GRADIENT EXISTS BETWEEN LAS-LAX EARLY THIS
   MORNING. CLOSE INSPECTION OF RECENT RAWS/MESOWEST DATA INDICATED
   SUSTAINED WINDS AVERAGING AROUND 15 MPH WITH GUSTS OCCASIONALLY OVER
   25 MPH OVER THE HIGHER TERRAIN AND THROUGH/BELOW PASSES. THESE WINDS
   MAY INCREASE SOMEWHAT DURING THE FIRST FEW HRS OF THE FCST PERIOD.
   HOWEVER...WITH UPPER RIDGING DEVELOPING EWD ACROSS THE AREA THROUGH
   TODAY...EXPECT THE PRESSURE GRADIENT TO WEAKEN /ALONG WITH DIURNAL
   EFFECTS/ DURING THE AFTERNOON. SUSTAINED WINDS SHOULD AVERAGE LESS
   THAN 20 MPH OVERNIGHT AS THE GRADIENT IS EXPECTED TO REMAIN WEAKER
   THAN THIS MORNING WITH EVEN LESS UPPER SUPPORT. VERY LOW RH READINGS
   /8-12 PERCENT/ WILL CONTINUE ACROSS THE AREA AS TEMPERATURES WARM
   WELL INTO THE 80S TO AROUND 90 IN LOWER ELEVATIONS WITH SUPPORT OF
   OFFSHORE WINDS. GIVEN MARGINAL WINDS THIS MORNING AND LACK OF
   EXPECTED STRONGER DEVELOPMENT THROUGH THE PERIOD...A CRITICAL FIRE
   WEATHER OUTLOOK AREA IS NOT ANTICIPATED.
   
   ...NRN/CENTRAL PLAINS...
   WELL ABOVE NORMAL TEMPERATURES WILL CONTINUE OVER MUCH OF THE REGION
   TODAY AS DOWNSLOPE FLOW AND UPPER RIDGING CO-EXIST. LOW DWPTS IN THE
   20S/30S WILL HELP PRODUCE MIN RH READINGS FROM 20-30 PERCENT. LACK
   OF A STRONG PRESSURE GRADIENT WILL KEEP SUSTAINED WINDS FROM
   INCREASING OVER 15 MPH.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0353 AM CST MON NOV 06 2006
   
   VALID 071200Z - 081200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A STRONG UPPER TROUGH OVER 500 HUNDRED MILES OFF THE BRITISH
   COLUMBIA/PAC NW COAST THIS MORNING WILL MOVE EWD AND INTO THE PAC
   NW/NRN ROCKIES TOMORROW. THIS SYSTEM WILL AID IN A BREAKDOWN OF THE
   UPPER RIDGE OVER THE ROCKIES. AT THE SURFACE THE RESULT WILL BE AN
   INTENSIFICATION OF THE LEE TROUGH AND INCREASING SSWLY WINDS OVER
   MUCH OF THE NRN/CENTRAL PLAINS. WARM TEMPERATURES COMBINED WITH
   THESE WINDS WILL SUPPORT NEAR CRITICAL FIRE WEATHER CONDITIONS TO
   PORTIONS OF THE REGION. ELSEWHERE ACROSS THE NATION...A
   WARMING/DRYING TREND IS IN STORE FOR THE SRN PLAINS AS UPPER RIDGING
   IS SUPPRESSED SWD INTO THE AREA. MEANWHILE...OFFSHORE GRADIENTS WILL
   WEAKEN AND BECOME ONSHORE OVER SRN CA AS UPPER TROUGHING APPROACHES
   THE REGION. INCREASING ONSHORE FLOW /ALBEIT INITIALLY SHALLOW/ WILL
   SUPPORT HIGHER RH READINGS IN LOWER ELEVATIONS AND REVERSAL IN WIND
   DIRECTIONS IN HIGHER ELEVATIONS.
   
   ...PORTIONS OF THE NRN/CENTRAL PLAINS...
   AS THE UPPER RIDGE BREAKS DOWN OVER THE NRN ROCKIES TOMORROW...THE
   LEE TROUGH SHOULD INTENSIFY OVER THE NRN/CENTRAL HIGH PLAINS. THE
   INCREASING MID LEVEL WLY FLOW COUPLED WITH A GREATER PRESSURE
   GRADIENT WILL SUPPORT INCREASING SFC SSWLY WINDS OVER MUCH OF THE
   REGION. ATTM...SUSTAINED WIND SPEEDS ARE EXPECTED TO RANGE BETWEEN
   15-20 MPH WITH GUSTS OVER 25 MPH. ANOTHER DAY OF WELL ABOVE NORMAL
   TEMPERATURES /15-20 DEG ABOVE AVERAGE/ AND LOW RH READINGS WILL
   SUPPORT CONDITIONS APPROACHING CRITICAL.
