   DAY 1 FIRE WEATHER OUTLOOK...REF AWIPS GRAPHIC PMWE98 KWNS
   VALID 271200-281200
     
   ...CRITICAL FIRE WEATHER AREA FOR - SRN CA...
   
   ...SYNOPSIS... 
   A MODERATE SANTA ANNA PATTERN WILL PERSIST ACROSS CA TODAY AS
   CUTOFF LOW IN VICINITY OF NRN BAJA CA DRIFTS SLOWLY SWWD...AND
   1035MB SURFACE ANTICYCLONE REMAINS IN PLACE ACROSS THE CENTRAL
   ROCKIES. A MODERATELY STRONG SEA-LEVEL PRESSURE GRADIENT WILL
   PERSIST ACROSS INTERIOR CA...ALLOWING FOR A CONTINUATION OF
   OFFSHORE LOW-LEVEL FLOW. THE POTENTIAL FOR HIGH WINDS WILL BE 
   AIDED BY A DEEP-LAYER ELY TO NELY VERTICAL WIND PROFILE IN PLACE
   ACROSS SRN CA. 
     
   ...CRITICAL FIRE WEATHER AREA 1 - SRN CA...
     
   PRIMARY CONDITIONS: STRONG WINDS / VERY LOW RH VALUES
   
   LATEST GUIDANCE SUGGESTS AREAS OF LOCALLY STRONG DOWNSLOPE/OFFSHORE
   WINDS WILL CONTINUE THROUGH MUCH OF THE DAY 1 PERIOD. STEEP...
   NEARLY DRY ADIABATIC LOW-LEVEL LAPSE RATES WILL ENHANCE VERTICAL
   MIXING AND ALLOW FOR STRONG ELY TO NELY WINDS OF 20-30 MPH...WITH
   LOCALLY STRONGER GUSTS TO 50 MPH OCCASIONALLY REACHING THE SURFACE.
   WINDS WILL LIKELY BE HIGHEST IN THE HILLS AND BELOW CANYONS AND
   MOUNTAIN PASSES. HIGH TEMPERATURES WILL BE UNSEASONABLY WARM AND
   SIMILAR TO THOSE OBSERVED YESTERDAY...RANGING FROM THE UPPER 70S TO
   LOW 80S IN THE COASTAL BASINS. WARM TEMPERATURES AND DOWNSLOPE WIND
   COMPONENT WILL CONTRIBUTE TO MINIMUM RH VALUES OF 10-20 PERCENT.
   LOCALLY POOR OVERNIGHT RH RECOVERY MAY PERSIST IN AREAS WHERE WINDS
   REMAIN STRONG DURING THE OVERNIGHT PERIOD.  
   
   ...SACRAMENTO VALLEY/EAST SIDE OF SAN FRANCISCO BAY...
   
   ELY TO NELY WINDS OF 15-25 MPH WILL BE POSSIBLE THIS MORNING...BUT
   WILL GENERALLY SUBSIDE TO 15 MPH OR LESS IN MOST AREAS BY THIS
   AFTERNOON. TEMPERATURES WILL REMAIN ABOVE NORMAL WITH HIGHS IN THE
   UPPER 60S TO MID 70S AT LOW ELEVATIONS. AREAS OF LOW RH RANGING
   FROM 10-25 PERCENT WILL DEVELOP BY THIS AFTERNOON.
   HOWEVER...GENERAL DECREASE IN WIND SPEED...ESPECIALLY COMPARED TO
   THE PAST TWO DAYS...WILL PRECLUDE ISSUANCE OF A CRITICAL FIRE
   WEATHER AREA THIS PERIOD.

   DAY 2 FIRE WEATHER OUTLOOK...REF AWIPS GRAPHIC PMWI98 KWNS
   VALID 281200-291200
     
   ...NO LARGE-SCALE SIGNIFICANT FIRE WEATHER CONDITIONS EXPECTED...
     
   ...SYNOPSIS... 
   DURING THE DAY 2 PERIOD...QUASI-STATIONARY UPPER LOW OFF THE SRN
   CA/NRN BAJA COAST WILL DRIFT SLOWLY WWD OR SWWD...RESULTING IN MID-
   LEVEL SELY FLOW ACROSS SRN CA. ADDITIONALLY...27/00Z ETA AND AVN
   SOLUTIONS SUGGEST SHOWERS AND THUNDERSTORMS ARE LIKELY ACROSS MUCH
   OF SRN CA LATE IN THE DAY. LIGHTER WIND SPEEDS AND HIGHER RH VALUES
   WITH RAIN/CLOUD COVER SHOULD BRING CRITICAL FIRE WEATHER CONDITIONS
   TO AN END ACROSS THIS REGION. 
   
   EAST OF THE UPPER LOW...A HIGHLY AMPLIFIED FLOW PATTERN WILL
   DEVELOP WITH A RIDGE FROM THE SRN HIGH PLAINS NWWD INTO THE PACIFIC
   NW...AND A PROGRESSIVE LARGE-SCALE TROUGH ACROSS THE ERN CONUS.
   GENERALLY COOL AND MOIST CONDITIONS WILL PRECLUDE DEVELOPMENT OF
   LARGE-SCALE CRITICAL FIRE WEATHER AREAS.
