   ...SYNOPSIS...

   ...FLORIDA...
   00Z SOUNDINGS REFLECT A DRY AIR MASS LINGERING OVER THE
   PENINSULA...AND LITTLE CHANGE IS ANTICIPATED TODAY. EXTENDED
   DURATIONS OF CRITICALLY LOW RELATIVE HUMIDITIES CAN BE EXPECTED ONCE
   AGAIN AS TEMPERATURES WARM INTO THE 60S. RELATIVE HUMIDITIES ACROSS
   INLAND LOCATIONS WILL LIKELY FALL INTO THE MID 20S...WHILE LOWER 30S
   CAN BE EXPECTED ELSEWHERE. THE EXCEPTION WILL BE WHERE ONSHORE
   WINDS...PRIMARILY ALONG THE EAST COAST AND OVER MUCH OF S FLORIDA
   WILL KEEP RELATIVE HUMIDITIES ABOVE CRITICAL VALUES. WITH A
   WEAKENING PRESSURE GRADIENT OVER THE AREA...WINDS WILL REMAIN LIGHT.
   
   
   ...SERN NM/FAR WRN TX...
   A MARGINAL FIRE THREAT WILL DEVELOP BY THE AFTERNOON AS TEMPERATURES
   WARM INTO THE UPPER 60S/LOWER 70S...WITH DRY AIR MASS RESULTING IN
   RELATIVE HUMIDITIES IN THE TEENS. DESPITE THE DEVELOPMENT OF A
   SURFACE LOW...SUSTAINED WIND SPEEDS ARE ONLY EXPECTED TO BE AROUND
   10 TO 15 MPH...AND LIGHT WINDS WITHIN THE MIXED LAYER WILL NOT
   SUPPORT STRONG GUSTS.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0145 AM CST FRI FEB 19 2010
   
   VALID 201200Z - 211200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER SHORT WAVE TROUGH OVER SRN CA WILL QUICKLY PROGRESS EWD
   THROUGH THE SWRN STATES. AS THIS OCCURS...A SURFACE LOW OVER ERN NM
   WILL DEVELOP EWD...REACHING N CNTRL TX LATE IN THE PERIOD. AHEAD OF
   THIS...A SURFACE HIGH EXTENDING FROM THE OHIO VALLEY SEWD WILL VERY
   SLOWLY SHIFT EWD...BECOMING CENTERED OVER THE MID ATLANTIC
   OVERNIGHT.
   
   ...FLORIDA...
   ALTHOUGH ANOTHER DAY OF CRITICALLY LOW RELATIVE HUMIDITIES IS
   ANTICIPATED ACROSS PORTIONS OF CNTRL/NRN FL...RELATIVE HUMIDITIES
   WILL SLOWLY BEGIN TO IMPROVE FOR PORTIONS OF THE
   PENINSULA...PRIMARILY IN RESPONSE TO AN UPPER LOW AND ATTENDANT
   SURFACE LOW OVER THE SWRN STATES. WINDS VEERING TO SELY AT THE
   SURFACE WILL GRADUALLY ALLOW DEW POINTS TO INCREASE FROM THE
   SOUTH...BEGINNING A GRADUAL END TO THE EXTENDED DRY PERIOD.
   HOWEVER...RECOVERY WILL BE SLOW...AND AREAS ACROSS INLAND CNTRL FL
   AND MUCH OF N FLORIDA WILL STILL DROP BELOW CRITICAL THRESHOLDS
   DURING THE DAY...THOUGH WITH LIGHT WINDS.
