   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK

   VALID 241200Z - 251200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR W-CNTRL FL...
   
   ...SYNOPSIS...
   A MID/UPPER-LEVEL HIGH WILL REMAIN ANCHORED OVER THE CNTRL
   APPALACHIANS/MID-ATLANTIC. ASSOCIATED SURFACE ANTICYCLONE WILL DRIFT
   SLOWLY SWWD OFF THE DELMARVA COAST TOWARDS THE CAROLINAS AND
   GRADUALLY WEAKEN WITH TIME. AS A RESULT...THE SURFACE PRESSURE
   GRADIENT OVER THE SOUTHEAST WILL SLOWLY RELAX. IN THE WEST...A
   LARGE-SCALE MEAN TROUGH WILL CONTINUE...ALTHOUGH STRONGER
   MID/UPPER-LEVEL FLOW WILL RETREAT NWD.
   
   ...CRITICAL FIRE WEATHER AREA - W-CNTRL FL...
   
   PRIMARY CONDITIONS: STRONG WINDS / LONG-TERM DROUGHT / LOW RH
   
   AT LEAST ONE MORE DAY OF MODERATELY STRONG ELY WINDS SHOULD CONTINUE
   BENEATH A 25 TO 35 MPH LOW-LEVEL JET OVERHEAD. SUSTAINED SURFACE
   SPEEDS OF 15 TO 25 MPH ARE LIKELY THIS AFTERNOON. LATEST GPS
   PRECIPITABLE WATER ESTIMATES AND WED EVENING RAOB SOUNDINGS HAVE
   INDICATED A STEADY INCREASE IN TOTAL MOISTURE ACROSS MUCH OF NRN FL
   OVER THE PAST 24-36 HOURS OWING TO PERSISTENT ELY FLOW AROUND THE
   EXPANSIVE MID-ATLANTIC ANTICYCLONE. INDICATIVE OF THIS MOISTURE
   INCREASE...ISOLATED SHOWERS AND ASSOCIATED LOW-LEVEL CLOUDINESS HAVE
   BEEN SPREADING WWD ACROSS NRN/CNTRL FL EARLY THIS MORNING AS WELL AS
   UPSTREAM OVER THE WRN ATLANTIC BASIN. WITH TEMPERATURES EXPECTED TO
   REACH THE UPPER 80S...A FEW HOURS OF MARGINALLY LOW RH CONDITIONS
   /AT TO SLIGHTLY BELOW 35 PERCENT/ SHOULD STILL DEVELOP OVER WRN
   PORTIONS OF CNTRL FL.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0429 AM CDT THU MAY 24 2007
   
   VALID 251200Z - 261200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   OVERALL LARGE-SCALE PATTERN SHOULD DE-AMPLIFY WITH BELT OF STRONGER
   MID-LEVEL WLYS BECOMING MORE ZONAL AND CONFINED TO THE NRN CONUS.
   THIS WILL HELP MAINTAIN A GRADUAL WEAKENING OF THE EXPANSIVE
   LOW/MID-LEVEL ANTICYCLONE CENTERED ACROSS THE CAROLINAS/SRN
   APPALACHIANS. MEANWHILE...A VIGOROUS IMPULSE AND ASSOCIATED
   LOW/MID-LEVEL CYCLONE SHOULD TRACK SLOWLY EWD ACROSS THE NRN
   ROCKIES/PLAINS.
   
   ...W-CNTRL FL...
   A FURTHER SLOW WEAKENING OF THE SURFACE PRESSURE GRADIENT ALONG WITH
   PERSISTENT ELY FLOW SHOULD RESULT IN SLIGHTLY LOWER WIND SPEEDS AND
   SLIGHTLY HIGHER RH VALUES ON FRI AFTERNOON COMPARED TO DAY 1.
   LOCALIZED CRITICAL CONDITIONS MAY YET CONTINUE WITH SUSTAINED
   SURFACE WINDS AROUND 15 TO 20 MPH AND RH VALUES APPROACHING 35
   PERCENT. GIVEN THE PROBABLE MARGINALITY/SHORT DURATION OF LOWER RH
   VALUES...WILL REFRAIN FROM INTRODUCING A CRITICAL AREA ATTM.
