   VALID 271200Z - 281200Z

   ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SRN WA AND FAR NRN
   ORE...

   ...SYNOPSIS...
   BROADLY CYCLONIC MID-LEVEL FLOW...WITH EMBEDDED DISTURBANCES...WILL
   OVERLIE PORTIONS OF THE WRN CONUS TO THE N-CNTRL CONUS. A SHORTWAVE
   TROUGH IS FORECAST TO MOVE EWD ACROSS PARTS OF WRN CANADA...WITH
   MID-LEVEL WLYS BECOMING ENHANCED ACROSS PARTS OF THE NWRN CONUS.
   THIS SHOULD CONTRIBUTE TO ENHANCED FIRE-WEATHER CONDITIONS ACROSS
   PARTS OF WA/ORE/ID/MT/WY/UT. ELSEWHERE...ELEVATED/CRITICAL
   FIRE-WEATHER CONDITIONS ARE UNLIKELY.

   ...PORTIONS OF CNTRL/SRN/ERN WA...NRN ORE...ID...CNTRL/WRN
   MT...WY...FAR NERN UT...
   DIURNALLY STRENGTHENED VERTICAL MIXING IS FORECAST TO MANIFEST THE
   ENHANCED FLOW ALOFT AT THE SFC...RESULTING IN MODERATE TO STRONG AND
   GENERALLY WSWLY TO WLY WINDS. STRONG SFC HEATING...COMBINED WITH
   AREAS OF DOWNSLOPE-FLOW-ENCOURAGED WARMING/DRYING...SHOULD ALLOW RH
   VALUES TO FALL SUFFICIENTLY LOW IN SUPPORT OF AN INCREASED
   FIRE-WEATHER RISK.

   CRITICAL FIRE-WEATHER CONDITIONS ARE EXPECTED TO OCCUR ACROSS
   PORTIONS OF SRN WA AND FAR NRN ORE. THIS INCLUDES PORTIONS OF THE
   COLUMBIA RIVER VALLEY AND VICINITY...WHERE LOCAL-FLOW CHANNELING IS
   FORECAST TO SUPPORT SUSTAINED WINDS OF 20-25 MPH. WITH MINIMUM RH
   AROUND 17-20 PERCENT AND DRY FUELS IN PLACE...CRITICAL DESIGNATION
   IS IN EFFECT. ELSEWHERE ACROSS THE REGION...ELEVATED FIRE-WEATHER
   CONDITIONS ARE ANTICIPATED...THOUGH SUSTAINED WINDS ARE NOT EXPECTED
   TO EXCEED 20 MPH WHERE CRITICALLY LOW RH VALUES OCCUR ON ANY MORE
   THAN A BRIEF/SPOTTY BASIS.
