   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   1235 AM CST WED DEC 15 2004
   
   VALID 161200Z - 171200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   HIGH PRESSURE WILL CONTINUE TO MAKE FOR COOL AND DRY CONDITIONS
   ALMOST EVERY WHERE ACROSS THE COUNTRY. ONE EXPANSIVE AREA OF HIGH
   PRESSURE OVER THE WRN STATES WILL CAUSE SANTA ANA WINDS TO DEVELOP
   OVER SRN CA WHERE IT WILL BE VERY DRY AND WINDY.  ANOTHER HIGH
   PRESSURE CENTER WILL BE WEAKENING OVER THE SERN STATES...BUT WILL
   STILL ALLOW FOR COOL AND DRY CONDITIONS.
   
   ...SRN CA...
   NELY WINDS WILL BE ONGOING THURSDAY MORNING...AND WILL REMAIN STRONG
   AND BECOME MORE GUSTY DURING THE DAYLIGHT HOURS AS MOMENTUM ALOFT
   MIXES DOWN TO THE SURFACE.  SUSTAINED NELY WIND SPEEDS OF 15-25 MPH
   WILL BE COMMON ALL THE WAY TO THE COAST BY EVENING...WITH SUSTAINED
   SPEEDS OF 20-30 MPH FARTHER INLAND AND IN THE HIGHER TERRAIN.  GUSTS
   WILL LIKELY EXCEED 50 MPH IN PLACES.  RH LEVELS WILL BE LOW AND
   AVERAGE 10-15 PERCENT AT PEAK HEATING WITH POOR RECOVERY OVERNIGHT.
   THE MITIGATING FACTOR WILL BE FUEL CONDITIONS WHICH ARE CURRENTLY
   NOT DRY ENOUGH TO WARRANT A CRITICAL FIRE WEATHER AREA AT THIS TIME.
    HOWEVER...A FEW MORE DAYS OF PERSISTENT DRYING COULD CHANGE THIS IN
   THE NEAR FUTURE.
   
   ...SERN U.S....
   RH LEVELS WILL BE HIGHER THAN ON PREVIOUS DAY AS AIR MASS BEGINS TO
   MODIFY.  ELY WINDS OFF THE ATLANTIC WILL RAISE DEWPOINTS ACROSS MUCH
   OF FLORIDA...BUT RH LEVELS WILL REMAIN LOW OVER THE FL PANHANDLE
   FROM 30-35 PERCENT.
