   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0140 AM CST SAT JAN 02 2010
   
   VALID 021200Z - 031200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   EARLY MORNING SATELLITE IMAGERY INDICATES A LEAD SHORTWAVE TROUGH
   OFF THE MID-ATLANTIC COAST EMBEDDED WITHIN A LARGER SCALE UPPER
   TROUGH CENTERED OVER THE LOWER GREAT LAKES/UPPER OH VALLEY.  THIS
   LEAD DISTURBANCE WILL EVOLVE INTO A CLOSED MID-LEVEL LOW INVOF NOVA
   SCOTIA/MAINE BY SUNDAY MORNING.  AT THE SURFACE...A COLD FRONT WILL
   CONTINUE TO MOVE SEWD ACROSS THE BAHAMAS/GREATER ANTILLES AS A
   COOL/DRY CONTINENTAL AIRMASS INFILTRATES FL LEADING TO SEVERAL HOURS
   OF CRITICALLY LOW RH ACROSS MUCH OF THE STATE.
   
   ...FL PENINSULA...
   POST-FRONTAL DRY/COOL CONDITIONS WILL LEAD TO CRITICALLY LOW
   RH DURING THE AFTERNOON HOURS AS PRECIPITABLE WATER VALUES HOVER
   NEAR 0.25 INCH.  LARGE SCALE SUBSIDENCE FAVORING SUNNY SKIES WILL
   AID IN TEMPS RISING INTO THE 50S N OF LAKE OKEECHOBEE AND 60S S. 
   MODIFYING FORECAST SOUNDINGS FOR FORECAST MAX TEMPS YIELDS STEEP 0-1
   KM LAPSE RATES WITH MIN RH IN THE 25-35 PERCENT RANGE.  SUSTAINED
   NW-NLY WINDS MAY BRIEFLY BE NEAR 15 MPH /HIGHER GUSTS 20-25 MPH/
   ENHANCING FIRE WEATHER POTENTIAL.  THIS SUGGESTS ISOLATED LOCALES
   MAY EXPERIENCE MARGINALLY STRONG SUSTAINED WINDS/LOW RH FOR SEVERAL
   HOURS SUPPORTING CRITICAL FIRE WEATHER CONDITIONS. 
   HOWEVER...SEASONALLY NORMAL KBDI VALUES /GENERALLY AOB 400/ OVER
   MUCH OF THE PENINSULA AND LACK OF EXISTING DROUGHT CONDITIONS
   SUGGEST THE OVERALL FIRE WEATHER THREAT MAY BE TEMPERED.
   
   ...FL PANHANDLE...
   MODEL OUTPUT SHOWS COOLER MAX TEMPS IN THE UPPER 40S TO NEAR 50
   ACROSS THIS REGION.  THIS WILL ONLY SUPPORT MIN RH FALLING INTO THE
   30-35 PERCENT RANGE.  MORE ABUNDANT RECENT RAINFALL OVER THE PAST
   MONTH AND SEASONALLY LOW KBDI VALUES SUGGEST THE FIRE WEATHER THREAT
   WILL REMAIN LIMITED DESPITE CRITICALLY LOW RH VALUES.

   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...

   SUPPORTING LOW RH DURING THE AFTERNOON HOURS.

   A WEAKENING PRESSURE GRADIENT FROM SATURDAY TO SUNDAY OVER THE
   REGION WILL LIKELY SERVE TO SLACKEN SUSTAINED WINDS /NEAR 10 MPH/. 
   MIN RH VALUES WILL PROBABLY FALL BELOW 35 PERCENT ACROSS A LARGE
   PART OF THE PENINSULA BUT HIGH TEMPERATURES WILL REMAIN RELATIVELY
   COOL /UPPER 40S PANHANDLE---50S NRN HALF OF PENINSULA---60S SRN
