Area Forecast Discussion
National Weather Service Pendleton OR
816 AM PDT SUN AUG 28 2016

.SHORT TERM...Today and tonight...Forecast area is under a dry
westerly flow today following yesterdays frontal passage. A large
upper level trough continues over western Canada. This trough will
begin to form a closed low along the west coast of Canada today and
overnight. This in turn will shift the mean trough position to off
the west coast and allow a ridge to begin building over the northern
Rockies. The result will be a developing dry southwesterly flow
overnight heading into Monday.

&&

.PREV DISCUSSION... /issued 257 AM PDT SUN AUG 28 2016/

SHORT TERM...Today through Tuesday Night...A broad upper trough
remains over the western US this morning with a westerly flow over
the area. Scattered high cirrus over the northern half of the area
will gradually lift north this afternoon. By late afternoon an
approaching wave along the British Columbia coast will start
deepening the trough offshore and turn the flow drier and more
southwesterly. Skies will clear out overnight and winds will remain
light. Highs today will be 2-3 degrees cooler than yesterday while
lows Sunday night will be similar to Saturday night. The dry
southwesterly flow will continue through Monday evening and dry and
sunny weather is expected. Highs Monday will warm to the upper 80s
to lower 90s with 80s in the mountains. Monday night models show
moisture coming through the trough into Central Oregon and the
eastern mountains after midnight. Partly to mostly cloudy skies will
spread across the area on Tuesday and a slight chance of showers and
thunderstorms will develop from Central Oregon into the eastern half
of the Columbia basin and over all of the Eastern Oregon mountains.
A few showers will linger overnight in the higher mountains. The
thunderstorms will not have much precipitation and lightning with
the storms may create fire weather concerns. The increased cloud
cover will keep temperatures Tuesday in the 80s with mid 70s to
lower 80s in the mountains. Perry

LONG TERM...Wednesday through Sunday...Models continue to struggle
with the evolution of a troughy pattern over the western U.S. this
week...with very little run to run consistency. As a result
confidence in the details of this forecast is below average. On
Wednesday the region will be in broad swly flow but it should be dry
for the most part. There will be just a few clouds around and near
normal temperatures. On Thursday and Thursday night it appears that
a shortwave trough will move across the area with some potential for
a few mountain showers and breezy west winds. Temperatures will be
cooler behind this system on Friday...averaging a few degrees below
normal. It will be dry Friday except for a few showers along the
cascade crest. There will be a very slight chance for mainly
mountain rain showers on Saturday before dry weather returns again
for Sunday. Temperatures over the weekend will be near normal. 78

AVIATION...12Z Tafs...VFR conditions are expected through the
forecast period. A few mid and high clouds will be around today and
tonight. Winds will be mostly westerly at 6-11 kt this afternoon and
light terrain driven tonight. 78
