   ...CRITICAL FIRE WEATHER AREA FOR SRN FL...
   
   ...SYNOPSIS...
   A DEEP UPPER TROUGH WILL REMAIN POSITIONED OVER THE EASTERN
   CONUS...WHILE A SMALL SCALE WAVE ROTATES THROUGH ITS BASE. SURFACE
   CYCLOGENESIS IS FORECAST TO OCCUR OVER THE ATLANTIC WITH THE
   EJECTING LOW AMPLITUDE S/W TROUGH...WHILE A COLD FRONT TRAILING TO
   THE SOUTH-SOUTHWEST MOVES ACROSS FLORIDA...AND THEN OFFSHORE BY
   EARLY AFTERNOON. BEHIND THE FRONT OVER FL AND THE SOUTHEASTERN
   CONUS...DRY AND BREEZY CONDITIONS WILL DEVELOP...LEADING TO ELEVATED
   FIRE WEATHER CONDITIONS.
   
   ...CRITICAL FIRE WEATHER AREA - SRN FL...
   
   PRIMARY CONDITIONS: LOW RH...WIND...ABNORMALLY DRY CONDITIONS
   
   SURFACE ANALYSIS EARLY WED MORNING SHOWS A VERY DRY AIRMASS RESIDING
   OVER THE SOUTHEASTERN CONUS /DEWPOINTS IN THE TEENS AND SINGLE
   DIGITS/...WHICH WILL SPREAD SOUTH ACROSS FL WITH THE PASSING COLD
   FRONT. AS AFTERNOON TEMPERATURES WARM INTO THE 50S AND 60S...RH
   VALUES WILL DROP INTO THE 20S. STEEPENING LAPSE RATES OVER THE
   LOWEST 1 KM IN ADDITION TO A STRENGTHENING SURFACE PRESSURE GRADIENT
   WILL RESULT IN SUSTAINED WINDS OF 15 TO 20 MPH /WITH LOCALLY HIGHER
   GUSTS/. THESE CONDITIONS...COMBINED WITH CONTINUED BELOW NORMAL
   PRECIPITATION...WILL SUPPORT A CRITICAL FIRE WEATHER AREA OVER THE
   SRN HALF OF THE FL PENINSULA.
   
   ...NRN FL INTO PORTIONS OF SRN AL AND GA...
   DRY AIR WILL SPREAD ACROSS THE REGION WEDNESDAY MORNING...RESULTING
   IN A LONG DURATION OF RH VALUES IN THE 20S THROUGH THE AFTERNOON.
   THIS DRYNESS WILL COMBINE WITH SUSTAINED WINDS AOA 15 MPH.
   HOWEVER...AFTERNOON TEMPERATURES WILL BE RELATIVELY COLD /GENERALLY
   BELOW 50/...WHICH WILL PRECLUDE A CRITICAL AREA.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0315 AM CST WED FEB 04 2009
   
   VALID 051200Z - 061200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   THE UPPER LEVEL TROUGH WHICH HAS BEEN POSITIONED ALONG THE EAST
   COAST DURING THE PAST FEW DAYS WILL BEGIN TO LIFT ENE INTO THE
   ATLANTIC ON D2. IN ITS WAKE...SURFACE HIGH PRESSURE WILL SLIDE SE
   FROM THE MID MS VALLEY REGION TOWARD THE FL PANHANDLE. THIS WILL
   ALLOW SURFACE WINDS TO RELAX ACROSS FL AND THE SOUTHEASTERN
   CONUS...THOUGH LOW RH VALUES WILL PERSIST. FARTHER WEST...AN UPPER
   LEVEL RIDGE WILL SHIFT EAST TOWARDS THE HIGH PLAINS. A WEAK SURFACE
   TROUGH WILL BECOME ORIENTED NORTH-SOUTH OVER THE REGION...WITH
   BREEZY SOUTH-SOUTHWESTERLY WINDS DEVELOPING...ACCOMPANIED BY
   MODERATING TEMPERATURES AND FALLING RH VALUES.
   
   ...ERN NM AND THE TX PANHANDLE...
   MODEL GUIDANCE IS IN FAIRLY GOOD AGREEMENT HIGHLIGHTING A
   COMBINATION OF LOW RH /IN THE TEENS TO UPPER SINGLE DIGITS/ ALONG
   WITH SUSTAINED WINDS NEAR 20 MPH OVER ERN NM INTO PORTIONS OF THE TX
   PANHANDLE. HOWEVER...A MID LEVEL RIDGE AXIS WILL BE PRESENT OVER THE
   REGION...RESULTING IN AN ILL-DEFINED SURFACE LEE TROUGH. DUE TO THE
   MARGINAL PATTERN AND WIND SPEEDS...A CRITICAL AREA WILL NOT BE
   ISSUED AT THIS TIME.
