   ...NO LARGE-SCALE SIGNIFICANT FIRE WEATHER CONDITIONS EXPECTED...
     
   ...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
   WILL REMAIN OVER THE GREAT BASIN INTO SRN CA WITH LOCALLY WINDY
   CONDITIONS.  A FEW DRY STORMS ARE EXPECTED INTO ERN ID. 
   THUNDERSTORMS WILL BE LIKELY INTO MT...BUT MOST WILL
   BE WET IN NATURE.  AREAS NEAR THE SRN APPALACHIANS WILL EXPERIENCE
   MARGINALLY LOW RH VALUES UNDER UPPER RIDGE.
     
   ...SRN NV / WRN UT...
   AFTERNOON SUSTAINED WINDS NEAR 15 MPH WITH GUSTS OF 20-25 MPH ARE
   EXPECTED ONCE AGAIN AS UPPER TROUGH REMAINS TO THE WEST OF THE
   AREA.  AFTERNOON MIN RH VALUES WILL RANGE FROM 10-15
   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.
   
   ...WY...
   PLUME OF HOT DRY AIR WILL MOVE INTO WRN WY DURING THE DAY...MAKING
   FOR LOCALLY BREEZY CONDITIONS WITH WINDS GENERALLY NEAR 15 MPH WITH
   HIGHER GUSTS...ALONG WITH MIN RH NEAR 15 PERCENT.  HAINES INDICES
