   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0202 AM CDT SUN SEP 30 2007
   
   VALID 301200Z - 011200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   LEAD SHORTWAVE TROUGH WILL TRANSITION NORTHEASTWARD FROM THE CENTRAL
   HIGH PLAINS TO THE WESTERN GREAT LAKES BY EARLY MONDAY...WHILE A
   SECOND AND MORE SUBSTANTIAL UPPER TROUGH DIGS SOUTHEASTWARD ALONG
   THE WEST COAST THROUGH THE PERIOD. AHEAD OF THIS SECONDARY
   SYSTEM...TEMPERATURES WILL QUICKLY WARM-UP TODAY ACROSS THE GREAT
   BASIN AND ADJACENT WESTERN STATES...WHILE GUSTY WINDS ARE LIKELY
   ACROSS PORTIONS OF THE PACIFIC NORTHWEST AS A COLD FRONT CROSSES THE
   REGION.
   
   FARTHER EAST...BROAD SYNOPTIC COLD FRONT WILL BE THE PRIMARY FOCUS
   FOR SHOWERS AND THUNDERSTORMS FROM THE UPPER MIDWEST INTO THE
   MISSOURI VALLEY AND SOUTH CENTRAL PLAINS...WITH GUSTY WINDS IN THE
   WAKE OF THE FRONT ACROSS THE CENTRAL PLAINS/MISSOURI VALLEY. DRY
   CONDITIONS WILL CONTINUE ACROSS THE SOUTHEAST STATES VIA THE
   PERSISTENCE OF THE UPPER RIDGE/SURFACE HIGH PRESSURE.
   
   ...SOUTHEAST STATES...
   BROAD UPPER RIDGE WILL REMAIN OVER THE SOUTHEAST QUADRANT OF THE
   CONUS TODAY...WITH SURFACE HIGH PRESSURE EXTENDING FROM THE
   NORTHEAST STATES INTO AREAS ALONG/EAST OF THE APPALACHIANS. THIS
   PATTERN WILL MAINTAIN A DRY AIRMASS ACROSS THE REGION...WITH
   RELATIVELY LOW RH AFTERNOON VALUES AROUND 30 PERCENT FOR A FEW HOURS
   DURATION. SLIGHTLY COOLER TEMPERATURES/HIGHER RH VALUES AND/OR
   SOMEWHAT LIGHTER WINDS SUGGEST THAT THE OVERALL FIRE DANGER WILL BE
   MORE MARGINAL AS COMPARED TO YESTERDAY.
   
   ...CENTRAL/EASTERN KS AND SOUTHEAST NEB...
   AS THE SHORTWAVE TROUGH/SYNOPTIC COLD FRONT CROSSES THE CENTRAL
   PLAINS...VERY STRONG WEST-NORTHWEST WINDS ARE EXPECTED ACROSS MUCH
   OF KS/NEB IN THE WAKE OF THE FRONT. STRONG WINDS THROUGH THE LOW/MID
   LEVELS AND AMPLE MOMENTUM TRANSFER WILL FAVOR SUSTAINED WIND SPEEDS
   OF 20-30 MPH THIS AFTERNOON...WITH GUSTS TO 40-45 MPH
   POSSIBLE...POTENTIALLY LEADING TO FAST FIRE SPREAD. MARGINAL RH
   VALUES AND/OR RECENT PRECIPITATION SHOULD TEND TO LIMIT THE OVERALL
   POTENTIAL...HOWEVER PORTIONS OF SOUTH CENTRAL/NORTHEAST KS ARE
   LOCALLY DRIER VIA AN ABSENCE OF RAINFALL OVER THE PAST 1-2 WEEKS.
   
   ...ORE/ID AND NORTHERN NV/NORTHERN CA...
   IN ASSOCIATION WITH THE STRONG WESTERN STATES UPPER TROUGH...A COLD
   FRONT WILL CROSS THE PACIFIC NORTHWEST TODAY...LIKELY REACHING
   PORTIONS OF ID AND EASTERN ORE BY THIS EVENING. MODERATELY
   STRONG/GUSTY WINDS ARE EXPECTED ALONG AND AHEAD OF THE COLD
   FRONT...HOWEVER COOL TEMPERATURES/SUFFICIENTLY HIGH RH VALUES
   SUGGEST THE CRITICAL FIRE WEATHER POTENTIAL IS CONSIDERABLY LIMITED.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0333 AM CDT SUN SEP 30 2007
   
   VALID 011200Z - 021200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AS A PROGRESSIVE LARGE SCALE REGIME CONTINUES...BROAD UPPER TROUGH
   IS FORECAST TO QUICKLY TRANSITION FROM THE WEST COAST TOWARD THE
   ROCKIES ON MONDAY...WITH AN ASSOCIATED COLD FRONT CROSSING THE
   INTERMOUNTAIN WEST/GREAT BASIN. THE COLD FRONT WILL BRING GUSTY
   WINDS TO PORTIONS OF THE INTERMOUNTAIN WEST AND GREAT BASIN...ALONG
   WITH A DISTINCT WIND SHIFT. IN THE EAST...THE UPPER RIDGE IS
   FORECAST TO GRADUALLY BREAK-DOWN...WITH SURFACE HIGH PRESSURE
   SHIFTING EASTWARD TO THE WESTERN ATLANTIC.
   
   ...WY/UT/EASTERN NV...
   GUSTY WINDS ARE EXPECTED ACROSS THE INTERMOUNTAIN WEST/GREAT BASIN
   ON MONDAY IN ASSOCIATION WITH THE STRONG UPPER TROUGH/COLD FRONT
   CROSSING THE REGION. THE STRONGEST WINDS ARE LIKELY TO OCCUR ACROSS
   WY MONDAY AFTERNOON...AND TO A LESSER EXTENT PORTIONS OF EASTERN NV
   INTO SOUTHWEST UT. SUSTAINED WINDS OF 20 MPH WITH HIGHER GUSTS WILL
   BE POSSIBLE...ALONG WITH A WIND SHIFT WITH THE PASSAGE OF THE COLD
   FRONT. IN SPITE OF THE STRONG/GUSTY WINDS AND WIND SHIFT...COOL
   TEMPERATURES/SUFFICIENTLY HIGH RH VALUES AND/OR MOIST FUELS SUGGEST
   CRITICAL FIRE WEATHER CONDITIONS ARE UNLIKELY.
   
   ...COASTAL SOUTHERN CA...
   IN THE WAKE OF THE UPPER TROUGH...SURFACE HIGH PRESSURE SHOULD
   QUICKLY BUILD ACROSS THE GREAT BASIN MONDAY NIGHT. INCREASING
   OFFSHORE GRADIENT COULD LEAD TO A BOUT OF GUSTY WINDS/REDUCED RH
   MONDAY NIGHT AND EARLY TUESDAY FOR THE COASTAL AREAS OF SOUTHERN CA.
   HOWEVER...CRITICAL FIRE CONDITIONS ARE NOT CURRENTLY EXPECTED.
   
   ...SOUTHEAST STATES...
   AS THE INFLUENCE OF SURFACE HIGH PRESSURE WEAKENS...DEWPOINTS AND
   AFTERNOON RH VALUES SHOULD CONTINUE TO INCREASE ACROSS THE SOUTHEAST
   STATES ON MONDAY...SUCH THAT CRITICAL FIRE CONDITIONS ARE NOT
   EXPECTED.
