   NWS STORM PREDICTION CENTER NORMAN OK

   VALID 171200Z - 181200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR COASTAL AREAS OF SOUTHERN
   CALIFORNIA...
   ...CRITICAL FIRE WEATHER AREA FOR EASTERN SOUTH
   CAROLINA/SOUTHEASTERN GEORGIA...
   ...CRITICAL FIRE WEATHER AREA FOR CENTRAL TEXAS...
   
   ...SYNOPSIS...
   A SURFACE HIGH PRESSURE SYSTEM WILL DOMINATE MOST OF THE WESTERN
   TWO-THIRDS OF THE UNITED STATES...AS A SURFACE LOW MOVES THROUGH THE
   OHIO RIVER VALLEY. A COLD FRONT STRETCHING SOUTHWARD FROM THIS LOW
   WILL MOVE THROUGH THE SOUTHEASTERN US...WITH GUSTY WINDS AHEAD OF
   THIS SYSTEM. FURTHER WEST...SANTA ANA CONDITIONS CONTINUE IN
   SOUTHERN CALIFORNIA.
   
   ...CRITICAL FIRE WEATHER AREA - COASTAL AREAS OF SOUTHERN
   CALIFORNIA...
   
   PRIMARY CONDITIONS: GUSTY SANTA ANA WINDS AND LOW TEMPERATURES/RH
   
   A SANTA ANA WIND EVENT WILL CONTINUE ON SATURDAY...AS GUSTY OFFSHORE
   WINDS ARE PRODUCED BY THE HIGH PRESSURE SYSTEM BUILDING OVER THE
   GREAT BASIN.  NORTH TO NORTHEAST WINDS ARE EXPECTED TO BE STRONG AND
   GUSTY AT TIMES...ESPECIALLY IN CANYONS AND PASSES...WITH GUSTS
   AROUND 40 MPH. SURFACE TEMPERATURES WILL BE QUITE WARM...WITH HIGHS
   IN THE 70S F...AND RELATIVE HUMIDITY VALUES NEAR THE 15 TO 20
   PERCENT RANGE. ADDITIONALLY...THE PALMER DROUGHT INDEX FOR THE
   REGION INDICATES AN ONGOING MODERATE DROUGHT...SO SURFACE FUELS ARE
   LIKELY FAIRLY DRY IN THE REGION.
   
   ...CRITICAL FIRE WEATHER AREA - EASTERN SOUTH CAROLINA/SOUTHEASTERN
   GEORGIA...
   
   PRIMARY CONDITIONS: GUSTY WINDS AND LOW RELATIVE HUMIDITIES
   
   SURFACE WINDS SPEEDS WILL INCREASE TO AROUND 15 MPH DURING THE
   AFTERNOON...WITH LOCALIZED HIGHER GUSTS FROM 20 TO 25 MPH...AHEAD OF
   A COLD FRONT THAT WILL MOVE THROUGH THE REGION AFTER 00Z. WHILE
   TEMPERATURES ARE NOT EXPECTED TO BE DRAMATICALLY WARM WITH HIGHS IN
   THE LOW TO MID 50S F...RELATIVE HUMIDITY VALUES IN THE DRY AIRMASS
   AHEAD OF THE FRONT WILL DROP TO BELOW 25 PERCENT IN SOME REGIONS
   DURING THE LATE AFTERNOON HOURS. THESE CONDITIONS COMBINE TO PROVIDE
   A CRITICAL FIRE WEATHER THREAT...MAINLY DURING THE AFTERNOON AND
   EARLY EVENING HOURS. RELATIVE HUMIDITY VALUES WILL RECOVER RATHER
   QUICKLY AFTER PASSAGE OF THE COLD FRONT IN THE EARLY EVENING.
   
   ...CRITICAL FIRE WEATHER AREA - CENTRAL TEXAS...
   
   PRIMARY CONDITIONS: GUSTY WINDS AND LOW RELATIVE HUMIDITIES
   
   A CRITICAL FIRE DANGER EXISTS ACROSS THE REGION AS NORTHWEST WINDS
   WILL INCREASE TO AROUND 20 MPH...WITH HIGHER GUSTS..IN THE WAKE OF A
   COLD FRONT THAT WILL PASS THROUGH THE REGION DURING THE
   MORNING...BRINGING A DRIER AIRMASS WITH DAYTIME RELATIVE HUMIDITY
   VALUES EXPECTED TO FALL TO AROUND 20 TO 25 PERCENT. SURFACE
   TEMPERATURES WILL BE FAIRLY COOL...IN THE MID 50S F...BUT THE
   COMBINATION OF GUSTY SURFACE WINDS AND LOW RELATIVE HUMIDITY VALUES
   WILL BRING CRITICAL FIRE WEATHER CONDITIONS.
   
   ...FLORIDA...
   
   RELATIVE HUMIDITY VALUES WILL AGAIN FALL BELOW 35 PERCENT FOR
   SEVERAL HOURS DURING THE EARLY TO LATE AFTERNOON. FIRE WEATHER
   CONDITIONS ARE NOT EXPECTED TO REACH CRITICAL LEVELS AS SURFACE WIND
   SPEEDS AND GUSTS ARE FORECAST TO BE SOMEWHAT LIGHTER IN THIS REGION
   THAN FURTHER NORTH...WITH SPEEDS AROUND 10 TO 15 MPH.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0502 AM CST SAT FEB 17 2007
   
   VALID 181200Z - 191200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AS A SURFACE HIGH PRESSURE SYSTEMS MOVES FROM THE CENTRAL PLAINS
   EASTWARD INTO THE SOUTHEAST U.S...A COLD FRONT AND AN ASSOCIATED
   UPPER LEVEL STORM SYSTEM WILL MOVE INTO THE WESTERN U.S. BRINGING
   PRECIPITATION TO THE NORTHWEST. GUSTY WINDS WILL DEVELOP IN THE
   CENTRAL PLAINS AHEAD OF A DEVELOPING LEE CYCLONE/TROUGH.
   
   ...TX PANHANDLE/SW OK/NW TX...
   SURFACE WIND SPEEDS WILL BECOME STRONG AND GUSTY IN RESPONSE TO AN
   INCREASING PRESSURE GRADIENT AHEAD OF A DEVELOPING LEE TROUGH IN
   CO/NM. SUSTAINED WIND SPEEDS ARE FORECAST TO BE NEAR 25 MPH WITH
   HIGHER GUSTS...AND SURFACE TEMPERATURES IN THE 60S F WITH LOW
   RELATIVE HUMIDITY VALUES AROUND 20 PERCENT WILL CONTRIBUTE TO A FIRE
   WEATHER THREAT. PORTIONS OF THIS AREA MAY NEED TO BE UPGRADED TO A
   CRITICAL RISK ON DAY1.
   
   ...FLORIDA AND ADJOINING SOUTHEASTERN STATES...
   ONCE AGAIN...FLORIDA WILL EXPERIENCE RELATIVE HUMIDITY VALUES
   DIPPING BELOW 35 PERCENT FOR A PORTION OF THE AFTERNOON. GUSTY
   SURFACE WINDS CAN BE EXPECTED ACROSS STATES ADJOINING FLORIDA IN THE
   WAKE OF A COLD FRONT THAT WILL MOVE THROUGH THE REGION ON
   SATURDAY...AND THIS DRY AIR MASS WILL ALSO CONTAIN LOW RELATIVE
   HUMIDITY VALUES FOR THAT REGION...BRINGING THE POSSIBILITY OF A DAY1
   UPGRADE TO A CRITICAL FIRE WEATHER RISK FOR THE
   REGION...HOWEVER...SOMEWHAT COOL TEMPERATURES IN THIS AIR MASS COULD
   MITIGATE THE FIRE WEATHER THREAT.
