   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0147 AM CST FRI NOV 16 2007
   
   VALID 161200Z - 171200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A NEGATIVELY-TILTED UPPER-LEVEL TROUGH CENTERED OVER THE NORTHEAST
   WILL EVOLVE INTO A CLOSED LOW OVER QUEBEC. AN UPPER LOW OVER NWRN
   SONORA WILL EJECT EWD REACHING FAR W TX BY EARLY SAT. EXPANSIVE
   SURFACE HIGH PRESSURE WILL SHIFT EWD FROM THE WRN GULF COAST TO THE
   SOUTHEAST. IN ITS WAKE...A LEE SURFACE TROUGH WILL MOVE SLOWLY EWD
   THROUGH THE GREAT PLAINS AS A SERIES OF WEAK MID-LEVEL IMPULSES
   CROSS THE N-CNTRL CONUS.
   
   ...SOUTHEAST...
   A DRY AIR MASS /SURFACE DEW POINTS IN THE 20S TO LOWER 30S/ HAS
   SPREAD SWD INTO CNTRL FL. CONTINUED MODEST N/NWLY WINDS WILL ALLOW
   PERVASIVE LOW RH THIS AFTERNOON...WITH VALUES AROUND 20 TO 30
   PERCENT AS TEMPERATURES WARM INTO THE 60S. THE RAPID APPROACH OF A
   SURFACE HIGH PRESSURE RIDGE WILL LEAD TO DIMINISHED LOW-LEVEL FLOW
   COMPARED TO THU. SUSTAINED AFTERNOON WINDS WILL RANGE FROM 8 TO 15
   MPH...WHICH SHOULD PROVIDE AN ENHANCED FIRE WEATHER THREAT.
   
   ...TX BIG COUNTRY NEWD THROUGH MUCH OF OK AND SERN KS/SWRN MO...
   A W/SWLY LLJ CENTERED FROM THE TX PANHANDLE TO CNTRL KS WILL PUSH
   EWD INTO ERN OK AND THE LOWER MO RIVER VALLEY BY THIS AFTERNOON. THE
   DEPTH OF THE MIXED BOUNDARY LAYER WILL REMAIN RELATIVELY
   SHALLOW...OWING TO A STRONG INVERSION BETWEEN 850 TO 750 MB. THE END
   EFFECT SHOULD BE MODERATE SUSTAINED WINDS /GENERALLY AROUND 15 TO 20
   MPH/. THE MOST FAVORED AREA FOR CRITICALLY LOW RH APPEARS TO BE OVER
   THE TX BIG COUNTRY...ALTHOUGH ABUNDANT UPPER-LEVEL CLOUDINESS
   EMANATING DOWNSTREAM OF THE NRN SONORA LOW SHOULD MITIGATE SURFACE
   HEATING SOMEWHAT. FARTHER NE...COOLER LOW-LEVEL TEMPERATURES SHOULD
   RESULT IN MARGINALLY LOW RH /AROUND 20 TO 25 PERCENT/. POCKETS OF
   SHORT DURATION CRITICAL CONDITIONS SEEM PROBABLE...BUT A WIDESPREAD
   CRITICAL EVENT IS NOT ANTICIPATED.

   CANADA/NERN CONUS THROUGH THE PERIOD AS A SHORT WAVE TROUGH DIGS
   ACROSS THE GREAT LAKES TOWARDS NEW ENGLAND. A SRN STREAM SHORT WAVE
   TROUGH SHOULD MOVE SLOWLY ACROSS TX/NRN MEXICO WITH INCREASED
   LOW-LEVEL MOISTENING NWD FROM THE WRN GULF OF MEXICO. AT THE
   SURFACE...A HIGH PRESSURE RIDGE WILL EXPAND FROM THE SOUTHEAST
   THROUGH THE WRN ATLANTIC BASIN. WEAK LOW PRESSURE WILL BECOME
   CENTERED OVER THE OH RIVER VALLEY BY SAT EVENING WITH A TRAILING
   COLD FRONT W/SWWD TOWARDS THE SRN HIGH PLAINS.
   
   ...CNTRL GA NEWD THROUGH THE CAROLINA PIEDMONT/PLAINS...
   MODERATE LOW-LEVEL SWLYS WILL DEVELOP SAT AFTERNOON AS WEAK LOW
   PRESSURE REACHES THE UPPER OH RIVER VALLEY AND A RIDGE AXIS REMAINS
   ANCHORED OVER NRN FL. THIS WILL HELP PRODUCE MODEST SUSTAINED
   SURFACE WINDS /FROM 10 TO 15 MPH/ AND WARMER TEMPERATURES /GENERALLY
   IN THE 60S/. WITH DEW POINTS HOLDING IN THE 20S...AFTERNOON RH
   VALUES WILL BECOME CRITICALLY LOW FROM AROUND 20 TO 25 PERCENT.
