   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0352 AM CDT WED SEP 24 2008
   
   VALID 241200Z - 251200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER-LEVEL TROUGH OVER THE NERN PACIFIC WILL GRADUALLY SHIFT EWD
   AND BECOME CENTERED ALONG THE PACIFIC NW COAST BY EARLY THU.
   ASSOCIATED BELT OF STRONG MID-LEVEL SWLYS /AOA 50 MPH AT 500 MB/
   WILL OVERSPREAD MUCH OF THE PACIFIC NW AND NRN INTERMOUNTAIN WEST.
   IN THE SOUTHEAST...CUTOFF LOW OFF THE CAROLINA COAST SHOULD SLOWLY
   MEANDER WWD.
   
   ...FAR NERN CA/NWRN NV...
   ON THE SRN FRINGE OF STRENGTHENING MID-LEVEL SWLYS...LOCALIZED
   CRITICAL CONDITIONS APPEAR PROBABLE N OF THE SIERRA MTNS. SUSTAINED
   SURFACE WINDS WILL LIKELY AVERAGE NEAR 20 MPH THROUGH THE AFTERNOON
   AS STEEP LOW-LEVEL LAPSE RATES PROMOTE VERTICAL MIXING. INSOLATION
   SHOULD REMAIN SUFFICIENT FOR TEMPERATURES TO WARM INTO THE 70S TO
   LOWER 80S. THIS WOULD RESULT IN RH VALUES AROUND 10 PERCENT.
   
   ...FL PANHANDLE...
   LOCALIZED/MARGINAL-DURATION CRITICAL CONDITIONS SHOULD DEVELOP
   DURING THE EARLY TO MID-AFTERNOON. MODERATE LOW-LEVEL NELYS /AROUND
   20-25 MPH AT 850 MB/ SHOULD LEAD TO SUSTAINED SURFACE WINDS NEAR 15
   MPH. WITH TEMPERATURES RISING INTO THE LOWER TO MIDDLE 80S...RH
   VALUES SHOULD DROP TO AROUND 30 PERCENT.
   
   ...CNTRL GA/FAR WRN SC...
   LOW-LEVEL N/NELYS WILL BE SLIGHTLY STRONGER COMPARED TO THE FL
   PANHANDLE REGION...LENDING TO SUSTAINED SURFACE WINDS OF 15 TO 20
   MPH. WITH SOME COMPONENT OF DOWNSLOPE FLOW OFF THE SRN
   APPALACHIANS...RH VALUES WILL LIKELY FALL TO BETWEEN 25 AND 30
   PERCENT AS TEMPERATURES REACH THE LOWER 80S. THIS MAY RESULT IN AN
   ENHANCED FIRE WEATHER THREAT GIVEN A RECENT LACK OF RAINFALL.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0456 AM CDT WED SEP 24 2008
   
   VALID 251200Z - 261200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A MID/UPPER-LEVEL SHORT WAVE TROUGH...INITIALLY CENTERED ALONG THE
   PACIFIC NW COAST...SHOULD PROGRESS E/NEWD TOWARDS THE NRN ROCKIES
   AND CANADIAN PRAIRIES THROUGH EARLY FRI. CUTOFF LOW OFF THE CAROLINA
   COAST SHOULD RETROGRADE WWD INTO THE CAROLINAS...WITH SURFACE
   CYCLONE APPROACHING THE PIEDMONT BY 26/12Z.
   
   ...CNTRL KY/MIDDLE TN/FAR NRN AL...
   A NEAR-CRITICAL FIRE WEATHER THREAT SHOULD DEVELOP AS LOW-LEVEL
   N/NELYS INTENSIFY COMPARED TO DAY 1...AND A WARM/DRY AIR MASS IS
   MAINTAINED. HOWEVER...STRONG WINDS ASSOCIATED WITH THE COASTAL
   CAROLINA CYCLONE SHOULD REMAIN ALONG AND E OF THE APPALACHIANS. MORE
   MODERATE WINDS /SUSTAINED SURFACE SPEEDS AROUND 15 MPH/ ARE EXPECTED
   FARTHER W FROM THE OH TO TN VALLEY. AS TEMPERATURES WARM BACK INTO
   THE LOWER TO MIDDLE 80S...RH VALUES SHOULD AGAIN PLUMMET TO BETWEEN
   20 TO 25 PERCENT. 
   
   ...CNTRL NV...
   A GLANCING INFLUENCE OF THE SHORT WAVE TROUGH SHIFTING ACROSS THE
   NRN INTERMOUNTAIN WEST SHOULD RESULT IN MODERATE DEEP-LAYER SWLY
   FLOW. SUSTAINED SURFACE SPEEDS ARE EXPECTED TO LARGELY REMAIN BELOW
   20 MPH AS RH VALUES DROP TO NEAR 10 PERCENT.
