   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0152 AM CST THU FEB 19 2009
   
   VALID 191200Z - 201200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR S CNTRL AND SERN TX...
   ...CRITICAL FIRE WEATHER AREA FOR FL PANHANDLE AND SUWANNEE
   VALLEY...
   
   ...SYNOPSIS...
   AN UPPER LOW WILL MOVE THROUGH THE GREAT LAKES REGION AND INTO NEW
   ENGLAND...WITH A TROUGH AXIS INITIALLY EXTENDING THROUGH THE
   APPALACHIANS AND EVENTUALLY MOVING OFFSHORE OF THE ATLANTIC COAST
   LATE IN THE PERIOD. MEANWHILE A STRONG SHORT WAVE TROUGH WILL DIVE
   SEWD INTO THE NRN HIGH PLAINS WHILE AN UPPER RIDGE DOMINATES THE
   WESTERN STATES. 
   
   AT THE SURFACE...A COLD FRONT WILL QUICKLY MOVE THROUGH NRN FL THIS
   MORNING THEN INTO CNTRL AND SRN FL THROUGH THE AFTERNOON AND
   EVENING. MUCH DRIER AIR WILL FOLLOW THIS AND MARGINAL RHS AND BREEZY
   CONDITIONS WILL BE WIDESPREAD ACROSS THE SOUTHEAST. IN THE FL
   PANHANDLE AND THE SUWANNEE VALLEY OF FL...CRITICAL CONDITIONS WILL
   BE POSSIBLE. MEANWHILE FARTHER W...SURFACE HIGH PRESSURE WILL
   CONTINUE TO SLIDE SWD...BECOMING STATIONED ROUGHLY OVER THE WRN GULF
   BY THE END OF THE PERIOD. DRY AND BREEZY CONDITIONS WILL AFFECT S
   CNTRL AND SERN TX WHERE THE DROUGHT HAS BEEN INTENSIFYING.
   
   ...CRITICAL FIRE WEATHER AREA - S CNTRL AND SERN TX...
   
   PRIMARY CONDITIONS: LOW RH...STRONG WINDS...DROUGHT
   
   SURFACE HIGH PRESSURE WILL CONTINUE TO BUILD SWD TODAY...REACHING
   THE WRN GULF LATE IN THE PERIOD. DRY CONTINENTAL NELY WINDS WILL BE
   PREDOMINANT THROUGH THE AFTERNOON...WITH SPEEDS OF 15 TO 20 MPH AND
   GUSTS TO 30 MPH. RHS WILL LIKELY DROP INTO THE MID 20S TO MID 30S AS
   TEMPERATURES WARM INTO THE 60S. DESPITE MARGINAL WINDS AND
   RHS...DROUGHT HAS BEEN INTENSIFYING ACROSS SRN TX AND LITTLE
   PRECIPITATION HAS BEEN RECEIVED OVER THE PAST FEW WEEKS. THIS WILL
   ENHANCE THE FIRE THREAT ACROSS THE AREA AS FUELS REMAIN DRY.
   
   ...CRITICAL FIRE WEATHER AREA - FL PANHANDLE AND SUWANNEE VALLEY...
   
   PRIMARY CONDITIONS: STRONG WINDS...LOW RH
   
   A COLD FRONT IS IN THE PROCESS OF MOVING THROUGH NRN FL THIS
   MORNING...AND SHOWERS AND THUNDERSTORMS ARE OCCURRING IN
   ASSOCIATION. WINDS WILL QUICKLY SHIFT TO THE NW FOLLOWING THE
   PASSAGE...AND A MUCH DRIER AIRMASS WILL OVERSPREAD THE SOUTHEAST.
   THE PRESSURE GRADIENT WILL STILL BE SOMEWHAT STRONG...AND SUSTAINED
   WINDS NEAR 20 MPH WITH GUSTS TO 30 WILL BE LIKELY. RHS WILL LIKELY
   DROP INTO THE LOWER 30S FOR SEVERAL HOURS. DESPITE RECENT
   RAINFALL...STRONG WINDS AND LOW RH SHOULD ACT TO ENHANCE THE FIRE
   THREAT.
   
   ...SERN OK/NERN TX/SWRN AR/NWRN LA...
   A MARGINAL FIRE THREAT WILL BE PREVALENT DURING THE AFTERNOON AS
   SUSTAINED NWLY WINDS NEAR 10 TO 15 MPH WITH HIGHER GUSTS ALIGN WITH
   RH VALUES IN THE LOWER 20S. TEMPERATURES WILL BE SOMEWHAT
   COOL...MAINLY LOW TO MID 50S.
   
   ...MUCH OF THE SOUTHEAST...
   DRY AND BREEZY CONDITIONS WILL PREVAIL TODAY...ALTHOUGH IN GENERAL
   COOL TEMPERATURES IN THE 50S AND LOWER 60S WILL LEAD TO MARGINAL
   RHS.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0229 AM CST THU FEB 19 2009
   
   VALID 201200Z - 211200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR NRN AND CNTRL FL...
   ...CRITICAL FIRE WEATHER AREA FOR ERN NM...NWRN TX...SWRN OK...
   
   ...SYNOPSIS...
   AN UPPER LOW WILL QUICKLY EXIT NEWD OUT OF NEW ENGLAND WHILE THE
   MAIN TROUGH AXIS CONTINUES TO MOVE OVER THE OPEN WATERS OF THE
   ATLANTIC. COOL AND DRY CONTINENTAL FLOW WILL FOLLOW...AND ALTHOUGH
   WINDS WILL GENERALLY BE LIGHTER...RHS WILL BE LOWER THAN THE
   PREVIOUS DAY ACROSS MOST OF THE SOUTHEAST.
   
   MEANWHILE FARTHER W...AN UPPER LOW WILL QUICKLY DIVE SEWD INTO THE
   NRN THEN CNTRL PLAINS. AHEAD OF THIS FEATURE...A SURFACE LOW WILL
   FORM INVOF OF SERN CO WHILE ARCTIC HIGH PRESSURE QUICKLY SLIDES INTO
   THE PLAINS TO THE N OF THIS. SWLY WINDS NEAR 20 TO 30 MPH WILL ALIGN
   WITH LOW RHS ACROSS ERN NM...NWRN TX...AND SWRN OK. FARTHER E ACROSS
   CNTRL OK AND TX WINDS WILL BE STRONG AS WELL...ALTHOUGH RHS WILL BE
   MARGINAL.
   
   ...CRITICAL FIRE WEATHER AREA - NRN AND CNTRL FL...
   
   PRIMARY CONDITIONS: VERY LOW RH
   
   SURFACE HIGH PRESSURE WILL BE POSITIONED OVER THE SOUTHEAST...WHILE
   FOLLOWING THE PASSAGE OF AN UPPER TROUGH...A COOL CONTINENTAL NWLY
   FLOW WILL CONTINUE TO ADVECT DRY AIR INTO THE SOUTHEAST. ALTHOUGH
   WINDS WILL BE LIGHTER THAN THE PREVIOUS DAY AND TEMPERATURES
   COOLER...OVERALL RHS ARE EXPECTED TO BE MUCH LOWER. VALUES IN THE
   UPPER TEENS TO LOWER 20S WILL BE COMMON ACROSS NRN FL WITH THE
   EXCEPTION OF THE EAST COAST...WHILE ACROSS CNTRL FL MID 20S TO LOWER
   30S CAN BE EXPECTED. THIS WILL ENHANCE THE OVERALL FIRE
   THREAT...ESPECIALLY ACROSS CNTRL FL WHERE MODERATE DROUGHT IS
   ONGOING.
   
   ...CRITICAL FIRE WEATHER AREA - ERN NM...NWRN TX...SWRN OK...
   
   PRIMARY CONDITIONS: STRONG WINDS...LOW RH...DROUGHT
   
   A SURFACE LOW WILL DEVELOP INVOF SERN CO AHEAD OF A STRONG UPPER
   SHORT WAVE DIVING SEWD INTO THE NRN AND CNTRL HIGH PLAINS. IN
   RESPONSE...STRONG SLY TO SWLY WINDS WILL OVERSPREAD THE SRN PLAINS.
   SUSTAINED WINDS OF 20 TO 30 MPH WITH HIGHER GUSTS WILL ALIGN WITH
   RHS IN THE TEENS AND LOWER 20S. THE CRITICAL OUTLINE MAY NEED TO BE
   EXTENDED EWD IN TOMORROWS FORECAST SHOULD LOWER RHS APPEAR LIKELY.
   
   ...N CNTRL TX/SRN OK...
   STRONG SLY WINDS OF 20 TO 30 MPH WITH HIGHER GUSTS WILL OVERSPREAD
   THE SRN PLAINS AHEAD OF A DEVELOPING SURFACE LOW INVOF SERN CO.
   ATTM...RH FORECASTS APPEAR TO BE SOMEWHAT MARGINAL...ALTHOUGH THIS
   IS QUESTIONABLE. GIVEN THE RECENT FRONTAL PASSAGE...GREATER MOISTURE
   SHOULD BE SLOW TO RETURN TO THE AREA...AND CURRENT THOUGHTS ARE THAT
   RHS MAY BE LOWER THAN FORECAST. SHOULD THIS BE THE CASE...THE
   CRITICAL OUTLINE WILL NEED TO BE EXTENDED EWD IN TOMORROWS FORECAST.
