   ...SYNOPSIS... 
   UPPER TROUGH WILL DEEPEN ALONG THE W COAST...MAKING FOR COOLER
   CONDITIONS INTO WA AND OREGON...AS WELL AS NRN ID.  HOT AND DRY AIR

   PERCENT...WHILE HAINES INDICES INCREASE TO MDT AND LOCALLY HIGH
   CATEGORIES BY LATE AFTERNOON.  COMBINATION OF DRY UNSTABLE
   ATMOSPHERE WITH SLIGHTLY HIGHER THAN AVERAGE WIND SPEEDS WILL CAUSE
   LOCALLY HAZARDOUS FIRE WEATHER CONDITIONS.
   
   ...ERN ID / EXTREME WRN MT...
   A WEAK SHORTWAVE TROUGH CURRENTLY OVER NRN NV WILL MOVE NEWD. 
   THERE WILL LIKELY BE ENOUGH MOISTURE FOR ISOLATED TO PERHAPS WIDELY
   SCATTERED DRY THUNDERSTORMS WITH ADDITION OF DAYTIME HEATING. 
   PRECIPITABLE WATER VALUES WILL AVERAGE 0.50-0.60 INCHES...THEREFORE
   LITTLE RAIN IS EXPECTED.
