   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SRN CA...
   
   ...SYNOPSIS...
   UPPER RIDGE WILL CONTINUE TO BUILD OVER THE WRN STATES PRODUCING
   VERY HOT AND DRY CONDITIONS OVER A LARGE AREA. STRONG SWLY FLOW
   AROUND PERIPHERY OF RIDGE WILL HELP ENHANCE WINDS ACROSS THE NRN
   SIERRA INTO NWRN NV...WITH LOCALLY STRONG WINDS OVER PORTIONS OF SRN
   CA AS WELL. A STRONG UPPER TROUGH OVER ERN CANADA INTO THE NERN
   STATES WILL HELP DRIVE AN AREA OF HIGH PRESSURE SWD THROUGH THE
   GREAT LAKES INTO THE OH VALLEY/MID ATLANTIC WITH COOLER DRIER
   CONDITIONS.
   
   ...CRITICAL FIRE WEATHER AREA - PORTIONS OF THE NRN SIERRA AND NWRN
   NV...
   
   PRIMARY CONDITIONS: GUSTY WLY WINDS...VERY LOW RH...HIGH HAINES
   INDEX
   
   INCREASED WLY WIND GUST POTENTIAL WILL EXIST TODAY DUE TO A
   SMALL/ENHANCED JET ALOFT. THE STRONGEST WINDS WILL BE AT RIDGE TOP
   BUT STRONG WIND GUSTS OVER 30 MPH ARE LIKELY IN DOWNSLOPE REGIONS AS
   WELL. IT WILL REMAIN HOT AND VERY DRY WITH RH NEAR 10 PERCENT E
   SLOPES. RH RECOVERY WILL REMAIN POOR OVERNIGHT WITH CONTINUED WIND
   GUSTS.
   
   ...CRITICAL FIRE WEATHER AREA - PORTIONS OF SRN CA...
   
   PRIMARY CONDITIONS: GUSTY WLY WINDS...VERY LOW RH AND HIGH HAINES
   INDEX
   
   STRONG AND GUSTY WINDS WILL DEVELOP THIS AFTERNOON INTO THE
   OVERNIGHT HOURS DUE TO THERMALLY INDUCED PRESSURE GRADIENT. WLY
   WINDS AROUND 20 MPH ARE ANTICIPATED WITH HIGHER GUSTS OVER ERN KERN
   COUNTY...NERN LOS ANGELES COUNTY...AND WRN SAN BERNARDINO COUNTY.
   THE WINDS WILL COMBINE WITH A VERY HOT AND DRY AIR MASS TO PRODUCE
   CRITICAL FIRE CONDITIONS BEGINNING THIS AFTERNOON AND CONTINUING
   INTO THE OVERNIGHT HOURS.
   
   ...AZ...MUCH OF NV...UT...SRN WY...
   VERY HOT AND EXTREMELY DRY CONDITIONS WILL PERSIST TODAY BENEATH
   STRONG UPPER RIDGE. SINGLE DIGIT RH AND A HIGH HAINES INDEX WILL
   FAVOR AFTERNOON PLUME DOMINATION. LARGE SCALE WINDS ARE ONLY
   EXPECTED TO AVERAGE NEAR 15 MPH SUSTAINED...BUT GUSTS WILL BE HIGHER
   ESPECIALLY IN FAVORED TERRAIN LOCALES.
   
   ...MD/NRN VA...
   MUCH DRIER AIR WILL ARRIVE IN A POST FRONTAL REGIME AS HIGH PRESSURE
   SHIFTS SWD ACROSS THE GREAT LAKES. RH VALUES WILL FALL INTO THE 20
   PERCENT RANGE THIS AFTERNOON WITH NLY WINDS OF 10-15 MPH. RELATIVELY
   LITTLE PRECIPITATION HAS FALLEN IN THE PAST FEW WEEKS OVER MUCH OF
   MD INTO NERN VA THUS A RELATIVE FIRE THREAT WILL EXIST THIS
   AFTERNOON.

   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF INTERIOR SRN CA...
   
   ...SYNOPSIS...
   UPPER RIDGE WILL CONTINUE TO BUILD OVER THE WRN U.S. WITH EXPANSIVE
   AREA OF HOT AND DRY WEATHER FROM CA INTO WY. LOCALLY STRONG WINDS
   WILL OCCUR OVER INTERIOR SRN CA AS WELL AS IN THE LEE OF THE NRN
   SIERRA. TO THE NE...LOW PRESSURE WILL DEEPEN OVER ERN MT AS A WEAK
   DISTURBANCE RIDES EWD ALONG EDGE OF UPPER RIDGE. INCREASED WLY WINDS
   WILL RESULT OVER WRN MT.  ELSEWHERE..HIGH PRESSURE WILL SETTLE OVER
   THE MID ATLANTIC WITH CONTINUED DRY WEATHER BUT LIGHT WINDS.
   
   ...CRITICAL FIRE WEATHER AREA - PORTIONS OF INTERIOR SRN CA...
   
   PRIMARY CONDITIONS: STRONG WLY WINDS...VERY HOT AND DRY CONDITIONS
   
   A MODERATELY STRONG PRESSURE GRADIENT WILL EXIST FROM THE SRN SAN
   JOAQUIN VALLEY INTO THE MOJAVE DESERT. GUSTY WLY WINDS OVER 20 MPH
   WILL RESULT MONDAY AFTERNOON IN ADDITION TO THE VERY HOT AND DRY
   WEATHER WITH SINGLE DIGIT RH AND TEMPERATURES OVER 100. RH RECOVERY
   WILL BE POOR OVERNIGHT AS WINDS CONTINUE.
   
   ...SRN CA/AZ/NV/UT/SRN WY/WRN CO...
   IT WILL BE VERY HOT AND EXTREMELY DRY WITH SINGLE DIGIT RH
   WIDESPREAD. THIS WILL RESULT IN A HIGH HAINES INDEX WITH HIGH
   POTENTIAL OF PLUME DOMINATED FIRES. WINDS WILL GENERALLY REMAIN AT
   OR BELOW 15 MPH ON THE LARGE SCALE...BUT LOCALLY HIGHER GUSTS ARE
   LIKELY GIVEN EXTREME THERMALLY INDUCED TURBULENCE.
   
   ...NRN SIERRA...
   INDICATIONS ARE THAT WINDS WILL NOT BE QUITE AS STRONG ON MONDAY
   AVERAGING NEAR 15-20 MPH. VERY LOW RH AND HOT TEMPERATURES WILL
   PERSIST HOWEVER WIND SPEEDS STRONGER THAN CURRENTLY FORECAST WOULD
   BRING ABOUT CRITICAL FIRE CONDITIONS ON A LARGER SCALE.

   WLY WINDS WILL INCREASE BEHIND A WEAK UPPER FEATURE AND W OF SURFACE
   LOW. SUSTAINED SPEEDS OF 15-20 MPH ARE LIKELY ALONG WITH WARM
