   ...CRITICAL FIRE WEATHER AREA FOR SRN WY...
   
   ...SYNOPSIS...
   RELATIVELY COOL BUT WINDY CONDITIONS WILL PREVAIL ACROSS THE NRN
   ROCKIES/PLAINS UNDER BROAD UPPER TROUGH WHILE VERY WARM CONDITIONS
   CONTINUE FROM THE GREAT BASIN/DESERT SW EWD ACROSS THE SRN PLAINS
   INTO THE SERN STATES. COMBINATION OF LOW RH AND STRONG WINDS WILL
   RESULT IN LOCALLY CRITICAL CONDITIONS OVER PORTIONS OF WY...WITH
   DROUGHT...HOT TEMPERATURES AND LOW RH NEARING CRITICAL LEVELS OVER
   THE CAROLINAS AND GA.
   
   ...CRITICAL FIRE WEATHER AREA - SRN WY...
   
   PRIMARY CONDITIONS: STRONG WINDS...LOW RH
   
   ENHANCED WLY FLOW ALOFT WITH UPPER TROUGH WILL CAUSE STRONG WINDS
   WITH SPEEDS OF 15-25 MPH SUSTAINED AND HIGHER GUSTS OVER 30 MPH
   LIKELY. RH LEVELS ARE EXPECTED TO BE MARGINAL...NEARING 15 PERCENT
   AT PEAK HEATING IN DOWNSLOPE AREAS.
   
   ...NC/SC/GA...
   VERY HOT AND DRY CONDITIONS WILL AGAIN PREVAIL TODAY. SURFACE TROUGH
   WILL FORM IN LEE OF THE APPALACHIANS AS WEAK LOW AMPLITUDE UPPER
   WAVE PASSES TO THE N. SWLY WINDS WILL INCREASE TO AROUND 10 MPH WITH
   HIGHER GUSTS. RH WILL DROP TO CRITICALLY LOW VALUES GENERALLY FROM
   20-30 PERCENT AWAY FROM THE COAST WITH TEMPERATURES BREAKING 100
   DEGREES. THE RESULT WILL BE MARGINALLY CRITICAL CONDITIONS THIS
   AFTERNOON GIVEN EXTREME DROUGHT IN PLACE.
   
   ...CNTRL AND ERN MT...
   STRONG WLY FLOW ALOFT WITH UPPER TROUGH WILL RESULT IN SUSTAINED WLY
   WINDS OF 20-25 MPH WITH HIGHER GUSTS. RH LEVELS ARE EXPECTED TO BE
   LARGELY ABOVE CRITICAL VALUES...AVERAGING FROM 20-30 PERCENT DUE TO
   COOL TEMPERATURES IN THE 70S TO LOWER 80S. 
   
   ...INTERIOR SRN CA...
   VERY HOT TEMPERATURES AND EXTREMELY LOW RH WILL AGAIN FAVOR
   AFTERNOON FIRE GROWTH DESPITE WEAK WINDS. AFTERNOON WIND GUSTS WILL
   BE MAINLY TERRAIN DRIVEN AND ERRATIC. POOR RH RECOVERY OVERNIGHT
   WILL MAINTAIN THE FIRE THREAT.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0407 AM CDT TUE AUG 21 2007
   
   VALID 221200Z - 231200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   UPPER RIDGE OVER THE GREAT BASIN WILL BREAK DOWN A BIT WITH
   INCREASING WINDS AND ISOLATED THUNDERSTORMS ALONG A WEAK COLD FRONT
   FROM SRN ID/NRN UT INTO NERN NV. WINDS WILL DECREASE ACROSS THE NRN
   ROCKIES AS MAIN ENERGY WITH UPPER LOW SHIFTS INTO CANADA. WINDS WILL
   INCREASE FARTHER S INTO THE LOWER CO RIVER VALLEY AND ACROSS THE SRN
   CA DESERTS WITH HOT TEMPERATURES AND LOW RH. LOW PRESSURE WILL
   DEEPEN OVER ERN CO/WRN KS WITH STRONG SLY WINDS ACROSS THE CNTRL/SRN
   PLAINS BUT A RELATIVELY MOIST AIR MASS WILL REMAIN THERE. FARTHER
   E...A WEAK COLD FRONT WILL EXTEND ACROSS SRN VA WITH VERY HOT
   TEMPERATURES AND LOW RH PERSISTING S OF THIS FRONT ACROSS MUCH OF
   NC/SC/GA.
   
   ...NERN NV INTO SERN ID/NRN UT AND WRN WY...
   AS UPPER TROUGH DIGS SWD...ISOLATED THUNDERSTORMS ARE LIKELY TO FORM
   ALONG A COLD FRONT WHICH WILL EXTEND FROM NERN NV ACROSS NRN UT/SERN
   ID WED AFTERNOON. A MIXTURE OF WET AND DRY STORMS ARE EXPECTED GIVEN
   A MODERATELY DRY SUB CLOUD LAYER WITH SURFACE TO LCL MEAN RH NEAR 30
   PERCENT. MODERATELY STRONG DEEP LAYER SHEAR AND STORM MOTIONS ALONG
   THE BOUNDARY SUGGEST SOME TRAINING OF ECHOES AND THEREFORE LOCAL
   WETTING RAINS MAY OCCUR. DRY STORMS WILL BE MOST LIKELY WITH SWD
   EXTENT WHERE RH IS LOWER.
   
   ...SRN CA INTO THE LOWER CO RIVER VALLEY AND SRN GREAT BASIN...
   WINDS WILL PICK UP AS UPPER TROUGH DIGS SWD INTO THE GREAT BASIN. IN
   GENERAL...SUSTAINED WLY TO SWLY WINDS NEAR 15 MPH ARE
   EXPECTED...WITH HIGHER GUSTS. THE INCREASED WINDS WILL COMBINE WITH
   SINGLE DIGIT TO LOWER TEENS RH AND VERY HOT TEMPERATURES TO INCREASE
   FIRE DANGER. SOME OF THE STRONGEST WINDS WILL BE ACROSS THE ANTELOPE
   VALLEY IN SRN CA WHERE SUSTAINED SPEEDS WILL EXCEED 20 MPH.
   
   ...CENTRAL CAROLINAS INTO GA/AL...
   VERY HOT AND DRY CONDITIONS WILL CONTINUE WITH HIGH TEMPERATURES
   OVER 100 F AND MIN RH FROM 20-30 PERCENT. WINDS WILL BE LIGHT...BUT
   VERY DRY FUELS ARE IN PLACE WHICH WILL KEEP FIRE DANGER ELEVATED.
