   ...CRITICAL FIRE WEATHER AREA FOR SRN CA...
   
   ...SYNOPSIS...
   A BROAD UPPER TROUGH WILL REMAIN OVER MUCH OF THE CENTRAL CONUS THIS
   PERIOD WITH ANOTHER AMPLIFICATION OCCURRING LATE IN THE DAY AND
   OVERNIGHT ACROSS THE NRN PLAINS. STRONG NWLY FLOW ON BACK SIDE OF
   THIS AMPLIFICATION WILL HELP SEND REINFORCING AREA OF HIGH PRESSURE
   SWD OUT OF CANADA INTO THE U.S. WHERE COOL AND DRY CONDITIONS WILL
   PERSIST. A STRONG PRESSURE GRADIENT WILL EXIST ACROSS SRN CA INTO AZ
   AND WILL RESULT IN CRITICAL FIRE WEATHER CONDITIONS OVER SRN CA WITH
   VERY LOW RH AND STRONG SANTA ANA WINDS.
   
   ELSEWHERE...HIGH PRESSURE WILL KEEP RH VALUES LOW FROM TX EWD ACROSS
   THE DEEP SOUTH STATES BUT WITH LIGHT WINDS.
   
   ...CRITICAL FIRE WEATHER AREA - SRN CA...
   
   PRIMARY CONDITIONS: STRONG OFFSHORE WINDS AND LOW RH
   
   STRONG NELY WINDS WILL BE ONGOING THIS MORNING AND WILL CONTINUE
   THROUGH THE PERIOD...PEAKING TONIGHT INTO SUN MORNING. SUSTAINED
   WINDS OF 30-40 MPH ARE LIKELY THROUGH PASSES AND CANYONS WITH HIGHER
   GUSTS OVER 50-60 MPH. RH LEVELS WILL DROP THROUGH THE PERIOD...WITH
   MIN VALUES AVERAGING 10-15 PERCENT BY AFTERNOON WITH LOCALLY LOWER
   VALUES. THE LOW RH WILL PERSIST OVERNIGHT WITH CRITICAL CONDITIONS
   PERSISTING INTO THE NEXT DAY.
   
   ...LOWER CO RIVER VALLEY (CA/AZ BORDER)...
   IT WILL BE DRY...WINDY AND MILD TODAY WITH HIGH PRESSURE OVER THE
   GREAT BASIN. NLY WINDS OF 15-25 MPH WILL BE LIKELY BY AFTERNOON
   WHILE HIGH TEMPERATURES RANGE FROM THE UPPER 50S SRN NV TO NEAR 70
   FARTHER S. THIS WILL RESULT IN LOW RH VALUES OF 10-15 PERCENT...AND
   NEAR CRITICAL FIRE CONDITIONS.
   
   ...DEEP SOUTH...
   PRESENCE OF A DRY POST FRONTAL AIR MASS AND DAYTIME HEATING WILL
   ALLOW RH VALUES TO DIP BELOW 30 PERCENT FOR A FEW HOURS FROM THE
   LOWER MS VALLEY EWD TO THE CAROLINAS. WINDS WILL BE VERY LIGHT AND
   GENERALLY UNDER 5 MPH WHILE TEMPERATURES STRUGGLE INTO THE 60S.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0415 AM CST SAT DEC 02 2006
   
   VALID 031200Z - 041200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR SRN CA...
   
   ...SYNOPSIS...
   AN ENORMOUS AREA OF HIGH PRESSURE WILL EXTEND FROM THE GREAT BASIN
   INTO THE APPALACHIANS AS UPPER TROUGH SWEEPS ESEWD ACROSS THE CNTRL
   U.S. THE STRONG PRESSURE GRADIENT AND DRY AIR MASS WILL MAINTAIN
   DANGEROUS FIRE CONDITIONS OVER SRN CA...WITH LESSER THREATS INTO AZ
   AND DEEP S TX.
   
   ...CRITICAL FIRE WEATHER AREA - SRN CA...
   
   PRIMARY CONDITIONS: STRONG OFFSHORE WINDS AND EXTREMELY LOW RH
   
   SANTA ANA WIND EVENT WILL BE ONGOING SUN MORNING AND WILL CONTINUE
   THROUGH THE PERIOD. STRONG WINDS AND VERY LOW RH WILL EXTEND
   OFFSHORE BY THIS TIME. RH LEVELS WILL BE DOWN FROM PREVIOUS DAY AND
   IN THE SINGLE DIGITS MOST PLACES WITH POOR RECOVERY OVERNIGHT.
   
   ...SWRN AZ INTO LOWER CO RIVER VALLEY...
   NELY WINDS OUT OF A STRONG AREA OF HIGH PRESSURE WILL KEEP FIRE
   DANGER ELEVATED. SPEEDS OF 15-20 MPH WITH HIGHER GUSTS WILL BE
   COMMON ALONG WITH LOW RH NEAR 10-15 PERCENT. TEMPERATURES WILL BE
   RELATIVELY COOL IN THE 60S WITH COOL TEMPERATURES OVERNIGHT.
   
   ...SRN TX...
   SURGING HIGH PRESSURE WILL CAUSE AN INCREASE IN WINDS WITH SUSTAINED
   SPEEDS NEAR 20 MPH AND HIGHER GUSTS. COOL TEMPERATURES WILL
   PREVAIL...BUT DEWPOINTS WILL BE LOW ENOUGH TO LOWER RH INTO THE
   25-35 PERCENT RANGE. GIVEN HIGH KBDI VALUES ACROSS THE
   REGION...WIND/RH COMBO WILL INCREASE FIRE DANGER.
   
   ...LOWER MS VALLEY INTO GULF COAST STATES...
   ANOTHER AREA OF HIGH PRESSURE WILL SURGE SEWD INTO THE LOWER MS
   VALLEY WITH INCREASING NLY WINDS AROUND 15 MPH WITH HIGHER GUSTS
   NEAR 20 MPH. TEMPERATURES WILL BE RELATIVELY COOL AND MAINLY IN THE
   50S...WITH RH DECREASING TO NEAR 30 PERCENT. THIS WILL CREATE
   SOMEWHAT FAVORABLE CONDITIONS FOR FIRES FOR A FEW HOURS DURING THE
   AFTERNOON...BEFORE TEMPERATURES FALL RAPIDLY LATE WITH STABILIZING
   ATMOSPHERE.
