   ...CRITICAL FIRE WEATHER AREA FOR SRN AND CNTRL WY/UT/SRN NV...
   
   ...SYNOPSIS...
   LARGE SCALE HEIGHT FALLS WILL CONTINUE ACROSS THE PACIFIC
   NORTHWEST/NRN ROCKIES...FURTHER DEEPENING EXTENSIVE UPPER TROUGH
   ACROSS THE WEST. VARIOUS SHORTWAVE TROUGHS MOVING THROUGH THE FAST
   FLOW WILL ENHANCE MODERATE/HEAVY PRECIPITATION ACROSS FAVORED
   TERRAIN AREAS IN THE INTERMOUNTAIN REGION. MAIN FIRE WEATHER CONCERN
   TODAY WILL BE THE VERY STRONG SOUTHWEST WINDS OVER THE GREAT BASIN
   THROUGH WY. MAIN SFC LOW WILL DEEPEN AS IT LIFTS NORTHEAST ACROSS
   SRN MANITOBA. STRONG COLD FRONT WILL EXTEND FROM NW MN/SE WY/CNTRL
   NV BY EARLY EVENING. AIRMASS BEHIND THIS BOUNDARY WILL BE ONE OF THE
   COLDEST OF THE SEASON...AND THE ASSOCIATED COOL TEMPS/PRECIPITATION
   WITH THIS SYSTEM WILL TEMPER FIRE WEATHER THREATS ACROSS MUCH OF THE
   NRN ROCKIES. AHEAD OF THE FRONT HOWEVER...VERY DRY AIRMASS AND
   STRONG WINDS WILL SUPPORT A CRITICAL FIRE WEATHER AREA.
   
   ...CRITICAL FIRE WEATHER AREA 1 - SRN AND CNTRL WY/UT/SRN NV...
   
   PRIMARY CONDITIONS: SUSTAINED SFC WINDS 20-30 MPH WITH HIGHER
   GUSTS/MINIMUM RH VALUES BELOW 15 PERCENT/DRY FUELS
   
   MINIMUM RH VALUES FELL BELOW 10 PERCENT ON SATURDAY AHEAD OF A
   STRONG COLD FRONT WHICH NOW EXTENDS FROM NW SD INTO NRN NV EARLY
   THIS MORNING. LOW RH VALUES ARE EXPECTED TODAY...ALTHOUGH IN SOME
   PORTIONS OF THE OUTLOOK AREA...RH VALUES MAY BE SLIGHTLY HIGHER.
   STEEP LAPSE RATES AND INCREASING SFC PRESSURE GRADIENT WILL ENHANCE
   SFC WINDS TODAY AHEAD OF THE FRONT TODAY. SUSTAINED WINDS WILL
   LIKELY RANGE FROM 20-30 MPH WITH OCCASIONAL HIGHER GUSTS. RECENT
   OBSERVATIONS INDICATE THAT THE FIRE DANGER CLASS IS HIGH OR VERY
   HIGH...WHICH WILL BE MAINTAINED TODAY AHEAD OF THE FRONT. MUCH
   COOLER AIRMASS WILL OVERSPREAD THE REGION ON MONDAY...SO FIRE
   WEATHER RISKS WILL DIMINISH BEHIND THE COLD FRONT.

   FNUS22 KWNS 020931
   
   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0431 AM CDT SUN OCT 02 2005
   
   VALID 031200Z - 041200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   DEEP WRN TROUGH BECOMES THE DOMINANT FEATURE ON MONDAY...AS INITIAL
   UPPER LOW MOVES EWD ACROSS CNTRL CANADA. ANOTHER SHORTWAVE WILL DIVE
   SEWD FROM THE ERN PACIFIC ON MONDAY...PROVIDING A REINFORCING SHOT
   OF COOLER AIR. SFC FRONT WILL BECOME QUASI-STATIONARY OVER THE GREAT
   BASIN WITH THE ACTIVE PORTION OF THE FRONT MOVING EWD OVER THE UPPER
   MIDWEST BY MON EVENING. EXTENDED MODELS CONTINUE TO SUGGEST
   INCREASING OFFSHORE WINDS ACROSS SRN CA BY LATE MONDAY INTO THE
   MIDDLE OF THE WEEK.  
   
   ALTHOUGH WINDY CONDITIONS WILL PERSIST ACROSS PORTIONS OF THE GREAT
   BASIN THROUGH UT/WY...MUCH COOLER TEMPERATURES/HIGHER RH VALUES AND
   PRECIPITATION WILL DIMINISH FIRE WEATHER THREAT.
   
   ...SRN CA...
   SFC WINDS WILL INCREASE LATE MONDAY INTO TUESDAY IN RESPONSE TO
   INCREASING PRESSURE GRADIENT. NUMERICAL MODEL GUIDANCE SUGGESTS
   SUSTAINED WINDS MAY BE IN THE 15-25 MPH RANGE ACROSS FAVORED TERRAIN
   AREAS...WITH THE THREAT INCREASING OVERNIGHT. LOWERING HUMIDITY
   VALUES COMBINED WITH STRONG OFFSHORE WINDS WILL INCREASE THE
   POTENTIAL FOR CRITICAL FIRE WEATHER CONDITIONS THROUGH AT LEAST
   WEDNESDAY.
