   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0256 AM CST THU JAN 08 2009
   
   VALID 081200Z - 091200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF NRN/CNTRL FL AND SERN
   GA...
   
   ...SYNOPSIS...
   LARGE-SCALE UPPER-LEVEL TROUGH ACROSS THE ERN CONUS WILL SHIFT
   OFFSHORE. SHORT WAVE TROUGH APPROACHING THE PACIFIC NW COAST SHOULD
   BE CENTERED FROM THE NRN HIGH PLAINS TO THE GREAT BASIN BY EARLY
   FRI.
   
   ...CRITICAL FIRE WEATHER AREA - PORTIONS OF NRN/CNTRL FL AND SERN
   GA...
   
   PRIMARY CONDITIONS: MODERATE WINDS / LOW RH / HIGH KBDI
   
   A COLD FRONT PASSAGE ON WED USHERED IN A VERY DRY AIR MASS OVER THE
   REGION WITH PW VALUES AROUND A QUARTER-INCH /PER 00Z RAOBS/.
   ALTHOUGH AIR MASS MODIFICATION APPEARS TO BE UNDERWAY BASED ON
   RECENT GOES SOUNDER AND GPS PW DATA...ABUNDANT INSOLATION AND
   MODERATELY STRONG LOW-LEVEL WLYS WILL SUPPORT ROBUST BOUNDARY LAYER
   MIXING AND THE LIKELIHOOD FOR BOTH CRITICAL RH/WIND THRESHOLDS TO BE
   MET AWAY FROM THE GULF COAST. AFTERNOON TEMPERATURES IN THE UPPER
   60S TO MIDDLE 70S SHOULD RESULT IN RH VALUES FALLING TO BETWEEN 25
   AND 35 PERCENT. WITH 850 MB WINDS AROUND 40 TO 45 MPH...SUSTAINED
   SURFACE SPEEDS FROM 15 TO 20 MPH SHOULD BE COMMON.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0400 AM CST THU JAN 08 2009
   
   VALID 091200Z - 101200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A POSITIVELY-TILTED SHORT WAVE TROUGH EXTENDING FROM THE NRN HIGH
   PLAINS TO THE GREAT BASIN SHOULD STRETCH FROM THE UPPER MS RIVER
   VALLEY TO SRN HIGH PLAINS BY EARLY SAT. A SURFACE COLD FRONT WILL
   SWEEP SWD ACROSS THE CNTRL/SRN PLAINS FRI AFTERNOON...REACHING THE
   WRN GULF COAST BY 12Z/SAT. STOUT SURFACE HIGH PRESSURE WILL BUILD
   OVER THE GREAT BASIN.
   
   ...PORTIONS OF WRN TX FROM THE PECOS VALLEY TO THE BIG COUNTRY...
   NEAR-RECORD WARM TEMPERATURES /IN THE 70S TO LOWER 80S/ ARE EXPECTED
   FRI AFTERNOON AHEAD OF A FAST-MOVING COLD FRONT. THIS WILL RESULT IN
   WIDESPREAD LOW RH FROM 8 TO 15 PERCENT. ALTHOUGH MODEL FORECASTS ARE
   CONSISTENT WITH DIMINISHING LOW-LEVEL WINDS AS THE FRONTAL BOUNDARY
   APPROACHES...THEY DIFFER WITH THE MAGNITUDE OF CHANGE. CONSENSUS
   SUGGESTS SUSTAINED WINDS AOA 20 MPH SHOULD BE OF SHORT DURATION AND
   LIMITED TO EARLY AFTERNOON...MITIGATING A CRITICAL AREA ISSUANCE.
   
   ...SRN CA COASTAL AREA...
   MODERATE TO LOCALLY STRONG OFFSHORE FLOW WILL COMMENCE FRI MORNING
   LEADING TO AREAS OF LOW RH BY AFTERNOON. DOWNSLOPE WARMING/DRYING
   EFFECTS WILL RESULT IN LITTLE IF ANY RH RECOVERY FRI NIGHT AS
   OFFSHORE FLOW CONTINUES. THIS SHOULD SERVE TO DRY OUT HIGH FUEL
   MOISTURES AFTER SIGNIFICANT LATE AUTUMN/EARLY WINTER PRECIPITATION.
