   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0346 AM CST WED JAN 10 2007
   
   VALID 101200Z - 111200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   PRIMARY LARGE SCALE FEATURES THIS FORECAST PERIOD WILL BE TWO
   PACIFIC STORM SYSTEMS.  THE LEAD TROUGH IS EXPECTED TO TRACK EWD
   ACROSS SRN CANADA/U.S. BORDER REACHING SRN MANITOBA BY 12Z
   THURSDAY...WHILE THE SECOND TROUGH...IMMEDIATELY UPSTREAM...DIGS
   SEWD INTO THE WRN STATES.  THE DEVELOPMENT OF ONSHORE FLOW ACROSS
   SRN CA WITH THE APPROACH OF THE UPPER TROUGH WILL INCREASE RH VALUES
   AND LOWER SURFACE TEMPERATURES.  THIS WILL BRING AN END TO THE
   CRITICAL SANTA ANA WIND EVENT FROM THE PAST FEW DAYS.
   
   MEANWHILE...ZONAL FLOW/FLAT RIDGE ARE EXPECTED TO DEVELOP ACROSS THE
   ERN STATES TODAY.  SURFACE HIGH PRESSURE AREA WILL MIGRATE EWD
   ACROSS THE GULF STATES/SRN APPALACHIANS TO MID ATLANTIC REGION...
   MAINTAINING DRY CONDITIONS.
   
   ...SOUTHERN PLAINS...
   SHARPENING LEE TROUGH WILL RESULT IN AN INCREASING PRESSURE GRADIENT
   AND MILDER TEMPERATURES ACROSS THE SRN PLAINS TODAY.  THE STRONGEST
   WINDS ARE EXPECTED FROM WEST CENTRAL/NRN TX TO ERN KS/WRN MO WHERE
   SUSTAINED WIND SPEEDS SHOULD REACH 20-30 MPH...WITH HIGHER GUSTS
   /40-45 MPH/.  THESE STRONG/GUSTY WINDS...MILD TEMPERATURES AND
   MODESTLY LOW RH VALUES /30-35 PERCENT/ WILL LEAD TO A HEIGHTENED
   FIRE DANGER.  THIS HEIGHTENED THREAT SHOULD EXTEND FROM NORTHWEST TX
   THROUGH WRN OK TO SERN KS WHERE PRECIPITATION DURING THE LAST 1-2
   WEEKS HAS BEEN VERY LOW PER CPC PRECIPITATION ANALYSIS.
   
   ...GA/NRN FL...
   THE AIR MASS WILL REMAIN DRY ACROSS THIS REGION TODAY...WITH
   SLIGHTLY COOLER TEMPERATURES THAN WERE OBSERVED ON TUESDAY. 
   ALTHOUGH AFTERNOON RH VALUES SHOULD FALL BELOW 30-35 PERCENT FROM
   NRN FL INTO GA...WEAKER WINDS DUE TO PROXIMITY OF THE SURFACE HIGH
   AND MODEST VERTICAL MIXING WILL LIKELY TEMPER THE CRITICAL FIRE
   WEATHER THREAT.

   VALID 111200Z - 121200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   LARGE SCALE UPPER TROUGH WILL CONTINUE TO MOVE SWD ACROSS THE WRN
   U.S. ON THURSDAY...RESULTING IN A DOWNSTREAM RIDGE BUILDING NWD
   ACROSS THE SERN STATES.  AT THE SURFACE...A COLD FRONT ASSOCIATED
   WITH A NRN STREAM TROUGH WILL MOVE EWD INTO THE GREAT LAKES...WHILE
   THE WRN EXTENT SPREADS SWD THROUGH THE CENTRAL INTO SRN PLAINS. 
   SURFACE HIGH PRESSURE RIDGE WILL EXTEND WSWWD THROUGH SE/GULF COAST
   STATES AS THE CENTER OF HIGH PRESSURE MOVES OFFSHORE.
   
   IN THE WEST...ONSHORE FLOW ACROSS SRN CA WILL SUPPORT COOLER
   TEMPERATURES...HIGHER RH VALUES AND THE POTENTIAL FOR PRECIPITATION.
   
   ...SOUTHEAST STATES...
   ELY SURFACE TRAJECTORIES ARE EXPECTED TO RESULT IN AN INCREASE IN
   MOISTURE/RH VALUES ON THURSDAY ACROSS NRN FL INTO SRN GA.  ALTHOUGH
   THURSDAY AFTERNOON RH VALUES MAY FALL TO AROUND 30 PERCENT FARTHER
   INLAND ACROSS CENTRAL/NRN GA AND ERN AL...WEAK WINDS ARE EXPECTED TO
   PRECLUDE A FIRE WEATHER THREAT.
