   ...NO AREAS...
   
   ...SYNOPSIS...
   EARLY MORNING WATER VAPOR IMAGERY SHOWS SEVERAL STORM SYSTEMS
   PROGRESSING THROUGH THE MODERATE 40-50 KT NORTHERN STREAM. A
   SHORTWAVE WAS DIVING INTO NRN NV...AND THIS WILL MOVE EWD INTO THE
   WRN HIGH PLAINS BY THIS EVENING. BEHIND THIS INITIAL IMPULSE...MID
   LEVEL FLOW WILL INCREASE ACROSS NRN CA AND THE GREAT BASIN TO AROUND
   50 KTS BY TUESDAY MORNING. MEANWHILE...A RIDGE WILL AMPLIFY A BIT
   TODAY OVER THE NRN ROCKIES...AS A STRONGER UPPER TROUGH APPROACHES
   THE PACIFIC NORTHWEST. AT THE SURFACE...A COLD FRONT WILL AFFECT THE
   NRN PLAINS WITH A STATIONARY BOUNDARY DRAPED ACROSS WRN KS/SRN
   WY/NRN UT. 
   
   THE STRONGEST SURFACE WINDS WILL BE ACROSS THE PLAINS...WITH LOCALLY
   STRONG WINDS ACROSS PORTIONS OF SRN CA/SERN AZ.
   
   ...SRN CA...
   DROUGHT CONDITIONS PERSIST ACROSS THIS AREA...AND LOW RH VALUES
   BELOW 10 PERCENT...COMBINED WITH TEMPERATURES IN THE 90S/100S AND
   LOCALLY STRONG WINDS / 20-30 MPH WITH HIGHER GUSTS / WILL MAINTAIN
   THE FIRE WEATHER THREAT ACROSS THE REGION. AN OUTLOOK AREA WILL NOT
   BE ISSUED DUE TO THE RELATIVELY SMALL AREA AFFECTED. 
   
   ...WRN HIGH PLAINS...
   STRONG SURFACE WINDS / 15-30 MPH WITH HIGHER GUSTS / ARE EXPECTED
   TODAY ACROSS PORTIONS OF ERN NM/ERN CO/WRN KS. ALTHOUGH RH VALUES
   WILL BE TOO HIGH TO WARRANT AN OUTLOOK...THE STRONG WINDS COMBINED
   WITH HIGH TEMPERATURES IN THE 90S WILL INCREASE THE POTENTIAL FOR
   WIND DRIVEN FIRES.

   VALID 081200Z - 091200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR ERN ID/WRN AND CNTRL WY/NERN UT...
   
   ...SYNOPSIS...
   A DEVELOPING STORM SYSTEM ALONG THE BC COAST WILL INCREASE MID LEVEL
   AND SURFACE WINDS ON TUESDAY. A 50-60 KT MID LEVEL JET IS FORECAST
   TO MOVE ACROSS THE PACIFIC NORTHWEST/GREAT BASIN ON TUESDAY. THIS
   WILL RESULT IN SURFACE WINDS OF 20-30 KTS WITH HIGHER GUSTS OVER
   PORTIONS OF THE NRN GREAT BASIN/WY. ELSEWHERE...A RIDGE WILL BUILD
   ACROSS THE SOUTHWEST...RESULTING IN A VERY DRY AIRMASS ACROSS THE
   REGION AND ELIMINATING THE CHANCE FOR THUNDERSTORMS. ISOLATED DRY
   TSTMS WILL BE POSSIBLE ACROSS ID/MT AND PORTIONS OF THE WRN HIGH
   PLAINS.
   
   ...CRITICAL FIRE WEATHER AREA 1 - ERN ID/WRN AND CNTRL WY/NERN UT...
   
   PRIMARY CONDITIONS: SUSTAINED SFC WINDS OF 20-30 MPH WITH LOCALLY
   HIGHER GUSTS/MINIMUM RH VALUES 5-10 PERCENT/EXTREME LONG TERM
   DROUGHT...
   
   SURFACE WINDS WILL INCREASE TO 20-30 MPH BY LATE MORNING ACROSS THE
   SNAKE RIVER VALLEY AND BY MID AFTN ACROSS THE REST OF THE OUTLOOK
   AREA. MINIMUM RH VALUES WILL FALL BELOW 10 PERCENT...WITH HIGH
   TEMPERATURES CLIMBING INTO THE 70S/80S. RECENT FIRE DANGER CLASS
   OBSERVATIONS INDICATE VERY HIGH TO EXTREME VALUES. WITH THE
   COMBINATION OF VERY STRONG WINDS AND DRY/WARM WEATHER...FIRE WEATHER
   CONDITIONS WILL RAPIDLY DETERIORATE BY TUESDAY AFTN. 
   
   IN ADDITION TO THE WINDS...ISOLATED DRY TSTMS WILL BE POSSIBLE. AS
   THE UPPER SYSTEM APPROACHES...LARGE SCALE LIFT AND MID LEVEL
   MOISTURE WILL INCREASE. POINT FORECAST SOUNDINGS SHOW VERY STEEP
   LAPSE RATES...AND A WELL MIXED BOUNDARY LAYER. INSTABILITY WILL BE
   SUFFICIENT FOR THUNDERSTORMS...AND SOME OF THESE MAY CONTAIN LITTLE
   OR NO RAIN.
