   ...CRITICAL FIRE WEATHER AREA FOR A SMALL AREA OF XTRM NERN CA AND
   NWRN NV...

   ...SYNOPSIS...
   AN UPPER LEVEL TROUGH WILL MOVE INTO THE WEST COAST BY THE END OF
   THE PERIOD.  THE UPPER RIDGE OVER THE WEST WILL SHIFT TOWARDS THE
   CNTRL PLAINS WHILE A TROUGH REMAINS OVER THE EAST COAST.  

   THE REMNANTS OF TROPICAL STORM ODILE MOVING INTO EXTREME SRN AZ WILL
   SPREAD RAIN AND THUNDERSTORMS OVER MUCH OF THE SOUTHWEST.

   ...NERN CA...NWRN NV AND S-CNTRL/SERN OREGON...
   WITH THE APPROACHING UPPER TROUGH...AFTERNOON AND EVENING WINDS OVER
   THE CRITICAL AND SURROUNDING ELEVATED AREA WILL STRENGTHEN WHILE
   HUMIDITY DROPS TO 15 TO 20 PERCENT.  HIGHS WILL BE MOSTLY IN THE
   80S.  

   THE CRITICAL AREA WILL SEE THE STRONGEST WINDS FOR THE LONGEST
   PERIOD OF TIME WITH SWLY WINDS 20 TO 30 MPH AND GUSTS TO 40 MPH. 
   ELSEWHERE IN THE ELEVATED AREA...SWLY WINDS OF 15 TO 25 MPH WITH
   SOME GUSTS TO 30 MPH ARE EXPECTED.  FUELS ACROSS THE CRITICAL AREA
   ARE EXTREMELY DRY.  EVEN ACROSS THE ELEVATED AREA...FUELS ARE MOSTLY
   DRY TO VERY DRY.  

   BY LATE IN THE PERIOD...SHOWERS AND THUNDERSTORMS SHOULD MOVE INTO
   NWRN CA AND WRN OREGON/WA IN ASSOCIATION WITH THE UPPER TROUGH. 
   MOSTLY WETTING RAINS ARE EXPECTED.

   SCATTERED MAINLY WET THUNDERSTORMS OVER PORTIONS OF SRN CA WILL
   BEGIN TO DIMINISH AS THE AREA SHIFTS EWD.  

   A FEW MIXED WET/DRY STORMS MAY ALSO BE POSSIBLE ACROSS CNTRL NV THIS
