   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0403 AM CDT MON SEP 24 2007
   
   VALID 241200Z - 251200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   LITTLE APPRECIABLE THREAT FOR CRITICAL FIRE WEATHER WILL EXIST
   TODAY. A BROAD UPPER-LEVEL TROUGH SPANNING THE NRN ROCKIES TO THE
   FOUR CORNERS WILL DEAMPLIFY SLIGHTLY AS IT GRADUALLY PROGRESSES NEWD
   ONTO THE NRN/CNTRL PLAINS BY EARLY TUE. DOWNSTREAM RIDGING WILL
   REMAIN STOUT ACROSS THE ERN THIRD OF THE CONUS...CONTRIBUTING TO
   WELL-ABOVE NORMAL TEMPERATURES AND MODEST WINDS FROM THE SRN
   APPALACHIANS NWD TO THE ERN GREAT LAKES. IN THE WEST...SURFACE HIGH
   PRESSURE WILL BUILD FROM THE PACIFIC NW ACROSS THE GREAT BASIN AND
   CNTRL INTERMOUNTAIN WEST. MIDDLING OFFSHORE FLOW WILL STILL BE
   ENOUGH TO AID IN SUBSTANTIAL DRYING ACROSS THE SW AND CA AFTER
   RECENT WIDESPREAD RAINFALL/MOIST CONDITIONS.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0406 AM CDT MON SEP 24 2007
   
   VALID 251200Z - 261200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AN UPPER-LEVEL TROUGH OVER THE NRN/CNTRL PLAINS ON EARLY TUE WILL
   DAMPEN AS AN UPSTREAM SHORT WAVE TROUGH DIGS SEWD TOWARDS THE NRN
   ROCKIES/HIGH PLAINS. SURFACE HIGH PRESSURE CENTERED OVER THE
   MID-ATLANTIC SHOULD WEAKEN AS IT BECOMES SQUASHED SWD BY LOW
   PRESSURE AND AN ASSOCIATED COLD FRONT APPROACHING THE ERN GREAT
   LAKES/OH RIVER VALLEY. AN EXPANSIVE AREA OF SURFACE HIGH PRESSURE
   WILL REMAIN ANCHORED ACROSS THE PACIFIC NW/CNTRL INTERMOUNTAIN WEST
   MAINTAINING LIGHT OFFSHORE FLOW AND AN INCREASINGLY DRY AIR MASS
   OVER THE SW AND CA.
   
   ...PORTIONS OF INTERIOR SRN NEW ENGLAND...
   ALTHOUGH THE PROBABILITY OF BOTH CRITICAL WIND/RH THRESHOLDS BEING
   BREACHED APPEARS SLIM...AN ENHANCED FIRE WEATHER THREAT MAY EVOLVE
   ON TUE AFTERNOON GIVEN RECENT SHORT-TERM DRYNESS. SWLY LOW-LEVEL
   FLOW WILL INCREASE SOMEWHAT AS THE SURFACE PRESSURE GRADIENT
   TIGHTENS...LEADING TO WARMER/POTENTIALLY MORE MOIST CONDITIONS
   COMPARED TO DAY 1. HOWEVER...MODEL GUIDANCE SUGGESTS RICHER
   LOW-LEVEL MOISTURE WILL NOT REACH THE REGION UNTIL TUE
   EVENING/NIGHT. WHERE OVERLAND TRAJECTORIES CAN BE MAINTAINED...RH
   VALUES MAY BECOME MARGINALLY LOW /AROUND 30 TO 35 PERCENT/...AS
   TEMPERATURES WARM THROUGH THE 80S. FORECAST SOUNDINGS SUGGEST
   BOUNDARY LAYER DEPTH WILL REMAIN SHALLOW AND THIS SHOULD HELP LIMIT
   SUSTAINED SURFACE WINDS TO AROUND 12 TO 18 MPH.
