National Weather Service Pendleton OR
239 PM PDT WED MAY 25 2016

.SHORT TERM...Tonight through Saturday...The upper level trough that
has been over the region the past few days will continue to shift
east tonight. Thus will see an increasingly dry northwest flow over
the region. Lingering, mainly mountain, showers will continue into
the evening, ending by midnight. Another upper low currently moving
into northwest British Columbia will slowly work south through B.C.
Thursday and Thursday night. This low will strengthen the westerly
onshore flow currently across the region. Winds will be locally
breezy tonight through Thursday morning. Breezy to windy conditions
are expected to spread over a larger portion of the area Thursday
afternoon and evening. Winds will be strongest in the Columbia River
Gorge and in the Kittitas Valley. At this time, expect winds in the
Gorge to run 25 to 35 mph with gusts around 45 mph, and have issued
an advisory. Winds will be just a bit under these values in the
Kittitas Valley and will hold off on advisory in this area. Precip
Thursday will be limited to a few showers over Wallowa county and
some slop over showers along the Cascade east slopes. The upper low
looks to remain largely in place over southwest Canada Friday into
Saturday. Thus the westerly flow will continue across the area. This
flow will keep some locally breezy winds going on Friday. Meanwhile
precip will be limited to along the Cascade east slopes and over our
eastern mountain zones. 90

.LONG TERM...Saturday night through Wednesday...an upper level
trough passing to the north over the weekend will provide some low
chance pops to the mountains areas across the northern portion of
the forecast area through Monday. Then a ridge of high pressure will
begin to build into the region from the west bringing warmer and dry
conditions through the remainder of the forecast period.
