   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0400 AM CDT TUE SEP 25 2007
   
   VALID 251200Z - 261200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A LARGE-SCALE UPPER-LEVEL TROUGH WILL BE MAINTAINED ACROSS THE
   N-CNTRL CONUS...AS A SHORT WAVE LIFTS NEWD FROM THE NRN PLAINS
   ACROSS THE GREAT LAKES WHILE AN UPSTREAM IMPULSE DIGS SEWD FROM
   BRITISH COLUMBIA TOWARDS THE NRN ROCKIES. A STOUT UPPER-LEVEL RIDGE
   ACROSS THE ERN CONUS WILL GRADUALLY BREAK DOWN AND SHIFT EWD OVER
   THE WRN ATLANTIC. SIMILARLY...SURFACE HIGH PRESSURE ALONG THE
   MID-ATLANTIC COAST WILL SLIDE E AND WEAKEN WITH THE APPROACH OF LOW
   PRESSURE AND AN ASSOCIATED COLD FRONT CROSSING THE GREAT LAKES
   THROUGH THE MID-MS RIVER VALLEY. AN IMMENSE AREA OF SURFACE HIGH
   PRESSURE WILL BUILD FROM THE NRN GREAT BASIN/INTERMOUNTAIN WEST
   ACROSS THE CNTRL ROCKIES/HIGH PLAINS. THIS WILL FURTHER INCREASE
   DRYING WITH LIGHT WINDS OVER THE SWRN CONUS.
   
   ...PORTIONS OF INTERIOR SRN NEW ENGLAND...
   AN ENHANCED FIRE WEATHER THREAT IS EXPECTED THIS AFTERNOON GIVEN
   RECENT DRYNESS. THE COMBINATION OF INCREASING SWLY LOW-LEVEL FLOW
   AND FULL INSOLATION...WILL LEAD TO WELL-ABOVE NORMAL TEMPERATURES IN
   THE 80S. ALTHOUGH THE SWLY FLOW WILL EVENTUALLY RESULT IN
   SUBSTANTIAL MOIST ADVECTION...THIS SHOULD HOLD OFF UNTIL THIS
   EVENING/OVERNIGHT. WHERE OVERLAND TRAJECTORIES CAN BE UPHELD...RH
   VALUES WILL LIKELY BECOME MARGINALLY LOW /AROUND 30 PERCENT/.
   SUSTAINED SURFACE WINDS WILL BE STRONGER COMPARED TO MON...BUT
   SHOULD LARGELY REMAIN MODERATE /FROM AROUND 12 TO 18 MPH/...GIVEN
   RELATIVELY SHALLOW BOUNDARY LAYER DEPTH.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0400 AM CDT TUE SEP 25 2007
   
   VALID 261200Z - 271200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   CRITICAL FIRE WEATHER POTENTIAL APPEARS TO BE LOW ACROSS MUCH OF THE
   CONUS ON WED. A LARGE-SCALE UPPER-LEVEL TROUGH WILL BE SUSTAINED
   ACROSS THE N-CNTRL CONUS AS A SERIES OF IMPULSES GYRATE IN AND
   AROUND THE BASE OF THE TROUGH. MUCH OF THE WRN CONUS WILL CONTINUE
   TO DRY OUT WITH GENERALLY LIGHT WINDS...AS EXPANSIVE SURFACE HIGH
   PRESSURE STAYS ANCHORED FROM THE PACIFIC NW TO THE CNTRL PLAINS.
   
   ...SERN MT...
   W/NWLY WINDS WILL INCREASE WED AFTERNOON BENEATH STRONG NWLY
   MID-LEVEL FLOW AS LOW-LEVEL LAPSE RATES STEEPEN. SUSTAINED SURFACE
   WINDS WILL LIKELY REACH 20 TO 25 MPH. ALTHOUGH TEMPERATURES SHOULD
   ONLY WARM TO NEAR NORMAL READINGS /MIDDLE 60S TO LOWER 70S/...RH
   VALUES MAY BECOME MARGINALLY LOW /AROUND 20 TO 25 PERCENT/ GIVEN THE
   STRENGTH OF DOWNSLOPE-ENHANCED DRYING. NEVERTHELESS...FAIRLY
   WIDESPREAD RAINFALL OVER THE PAST WEEK ALONG WITH RECENT COOL/MOIST
   CONDITIONS SHOULD ASSUAGE ANY CRITICAL THREAT DESPITE LONGER-TERM
   DRYNESS.
