AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PENDLETON OREGON
800 PM PDT THU JUL 8 2004

.SHORT TERM...IT IS ANOTHER QUIET EVENING ACROSS THE FORECAST AREA
WITH CLEAR SKIES AND LIGHT WINDS.  THE CURRENT DRY WESTERLY FLOW
ALOFT WILL BECOME MORE SOUTHWEST AS AN UPPER TROUGH SWINGS DOWN FROM
THE GULF OF ALASKA ALONG THE COAST.  THIS WILL CAUSE THE ATMOSPHERE
TO GRADUALLY BECOME MORE UNSTABLE.  MOISTURE WILL BE LIMITED ON
FRIDAY SO THE FORECAST AREA WILL REMAIN DRY.  HOWEVER MOISTURE WILL
BEGIN TO BE TRANSPORTED NORTHWARD ON SATURDAY.  THIS WILL HELP TO
DESTABILIZE THE ATMOSPHERE EVEN MORE.  AS SUCH THERE WILL BE A
CHANCE OF AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS FROM THE
BLUE MOUNTAINS AND JOHN DAY HIGHLANDS EASTWARD.  THIS PATTERN WILL
CONTINUE THROUGH MONDAY.  THE AREA OF SHOWERS AND THUNDERSTORMS WILL
INCREASE IN COVERAGE AND EXPAND TO THE SOUTHWEST TO INCLUDE THE
CENTRAL OREGON AREAS BY LATE MONDAY.  DUE TO THE SOUTHWEST FLOW
ALOFT TEMPERATURE WILL ALSO BE ON A WARMING TREND...SLOW AT FIRST
BUT THEN INCREASING TOWARD THE BEGINNING OF NEXT WEEK WITH READINGS
BACK UP IN THE 90S VALLEYS/BASINS AND 70S TO MID 80S MOUNTAINS.
