   ...CRITICAL FIRE WEATHER AREA FOR NORTHWEST/NORTH CENTRAL MT...
   
   ...SYNOPSIS...
   PACIFIC NORTHWEST UPPER TROUGH WILL BEGIN TO WEAKEN/SHIFT
   NORTHEASTWARD TODAY ACROSS ID/MT...LEADING TO GUSTY WINDS AND A
   COMBINATION OF DRY/WET THUNDERSTORMS ACROSS THE NORTHERN ROCKIES.

   EXIST ACROSS THE SOUTHERN PLAINS...WITH HOT TEMPERATURES AND
   ISOLATED AFTERNOON THUNDERSTORMS ACROSS THE SOUTHEAST STATES.

   SHORTWAVE TROUGH ACROSS EASTERN PORTIONS OF ORE/WA EARLY THIS
   MORNING WILL QUICKLY CROSS ID/MT THROUGH TONIGHT. ASSOCIATED WITH

   WILL RESULT IN STRONG/GUSTY DOWNSLOPE WINDS FOR AREAS ALONG/EAST OF
   THE DIVIDE THIS AFTERNOON...INCLUDING THE CUT BANK/GREAT FALLS
   VICINITIES. SUSTAINED WIND SPEEDS COULD REACH 20-30 MPH...WITH
   HIGHER GUSTS. IN ADDITION...A FEW THUNDERSTORMS WITH GUSTY/ERRATIC
   WINDS CANNOT BE RULED OUT THIS AFTERNOON ACROSS NORTHWEST/NORTH
   CENTRAL MT...HOWEVER THE RELATIVELY GREATER PROBABILITY/COVERAGE
   SHOULD EXIST ACROSS SOUTHWEST MT/CENTRAL ID.
   
   ...CENTRAL ID/SOUTHWEST MT...
   LARGE SCALE ASCENT WITH UPPER TROUGH AND OROGRAPHIC LIFT WILL LEAD
   TO ISOLATED WET/DRY THUNDERSTORMS ACROSS CENTRAL ID/SOUTHWEST MT
   THIS AFTERNOON. GUSTY WINDS WILL BE POSSIBLE IN VICINITY OF ANY
   THUNDERSTORMS.
   
   ...EASTERN NV/INTERIOR SOUTHERN CA INTO WESTERN UT/NORTHWEST AZ...

   AIRMASS...GUSTY SOUTHERLY WINDS ARE EXPECTED THIS AFTERNOON FROM
   PORTIONS OF EASTERN NV/INTERIOR SOUTHERN CA INTO WESTERN
   UT/NORTHWEST AZ. SUSTAINED WIND SPEEDS SHOULD AVERAGE AROUND 15
   MPH...WITH GUSTS TO AROUND 30 MPH...AND MINIMUM RH VALUES IN THE
   8-15 PERCENT RANGE.
   
   ...SOUTHERN HIGH PLAINS...
   ON THE WESTERN PERIPHERY OF THE UPPER RIDGE...HOT/BREEZY CONDITIONS
   ARE AGAIN EXPECTED ACROSS THE SOUTHERN HIGH PLAINS THIS AFTERNOON.
   SUSTAINED SOUTHERLY WINDS MAY EXCEED 15 MPH THIS AFTERNOON ACROSS
   MUCH OF OK/WEST TX AND FAR EASTERN NM. HIGH TEMPERATURES WILL LIKELY
   REACH THE UPPER 90S IN MOST LOCALES...ALONG WITH MARGINALLY LOW RH
   VALUES.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0357 AM CDT TUE AUG 07 2007
   
   VALID 081200Z - 091200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR NORTHWEST/NORTH CENTRAL MT...
   
   ...SYNOPSIS...
   IN WAKE OF THE SHORTWAVE TROUGH CROSSING THE NORTHERN INTERMOUNTAIN
   REGION TODAY...A SECONDARY/MORE PRONOUNCED UPPER TROUGH WILL CROSS
   THE WESTERN CANADIAN PROVINCES ON WEDNESDAY. THIS WILL KEEP A
   MODERATELY STRONG BELT OF MID/UPPER FLOW FROM THE PACIFIC NORTHWEST
   INTO THE DAKOTAS. GIVEN THE PREVALENCE OF DRIER WESTERLY FLOW
   ALOFT...THUNDERSTORMS SHOULD BE CONSIDERABLY DIMINISHED ACROSS THE
   ROCKIES ON WEDNESDAY.
   
   ASIDE FROM THE POSSIBILITY OF CRITICAL FIRE WEATHER CONDITIONS
   ACROSS MT...SIMILAR TO TUESDAY...HOT/BREEZY CONDITIONS ARE AGAIN
   EXPECTED WEDNESDAY ACROSS PORTIONS OF THE SOUTHERN GREAT BASIN...AS
   WELL AS THE SOUTHERN PLAINS OF OK/TX.
   
   ...CRITICAL FIRE WEATHER AREA - NORTHWEST/NORTH CENTRAL MT...
   
   PRIMARY CONDITIONS: GUSTY WESTERLY WINDS
   
   WITH A MAINTENENCE OF MODERATELY STRONG WESTERLY FLOW ALOFT VIA
   UPPER TROUGH ACROSS WESTERN CANADA...ANOTHER BOUT OF GUSTY WESTERLY
   DOWNSLOPE WINDS IS EXPECTED WEDNESDAY AFTERNOON/EVENING IN AREAS
   ALONG AND EAST OF THE DIVIDE IN NORTHWEST/NORTH CENTRAL MT. ALTHOUGH
   TEMPERATURES MAY BE SLIGHTLY COOLER WITH SLIGHTLY HIGHER RH
   VALUES...AMPLE MIXING WITH THE POTENTIAL FOR STRONG/GUSTY WINDS OF
   20-30 MPH SUGGESTS A CRITICAL FIRE WEATHER THREAT.
