.SHORT TERM...HAVE RECENTLY ISSUED AN UPDATE TO REMOVE DRY
THUNDERSTORMS FOR THE REST OF THE MORNING. SURFACE AND SPOTTER
REPORTS INDICATE RAIN IS REACHING THE GROUND AND MORNING RAOBS

COLUMBIA BASIN AND BLUE MOUNTAIN FOOTHILLS. IN THE MOUNTAINS IT WILL
BE MOSTLY IN THE 80S TO LOWER 90S. THE NEW GFS RUN IS ADVERTISING AN
UPPER TROUGH WITH SOME MONSOON MOISTURE FROM THE SOUTH TO WORK ITS
WAY NORTHWARD INTO THE FORECAST AREA ON THURSDAY AS THE UPPER RIDGE
AXIS MOVES TO THE EAST AND ALLOWS THE FLOW ALOFT TO BECOME MORE
SOUTHERLY. BEING THAT THE MODELS USUALLY HAVE POOR RUN TO RUN
CONSISTENCY AND MODEL TO MODEL CONSISTENCY AT THIS RANGE (7 DAYS
OUT) WILL LEAVE FORECAST DRY FOR NOW AND JUST ADD SOME CLOUDS.
BEYOND THURSDAY HOT AND DRY CONDITIONS WILL CONTINUE AS ANOTHER
UPPER RIDGE BECOMES RE-ESTABLISHED OVER THE PACIFIC NORTHWEST ON
FRIDAY. 88

REGION. 88

&&

.FIRE WEATHER...AS STATED IN THE SHORT-TERM DISCUSSION...THE RED
FLAG WARNING WILL BE EXTENDED UNTIL 3 PM THIS AFTERNOON.  ALTHOUGH
THE AIR MASS WILL MOISTEN AND A FEW THUNDERSTORMS MAY PRODUCE
WETTING RAIN (I.E. AMOUNTS GREATER THAN 0.1 OF AN INCH)...THE
FORECAST AREA HAS BEEN UNDER A DRY SPELL FOR A COUPLE OF WEEKS AND
THE AREAS UNDER THE WARNING HAVE GRASSES AND OTHER FINE FUELS WITH
VERY LOW MOISTURE.  SMITH
