.SHORT TERM...
Tonight through Sunday Night...Southwesterly flow will prevail
over the region through the short term period. Several weak
disturbances will move through the flow over the weekend.

Any lingering precipitation over the eastern Oregon mountains
should come to an end this evening.

Dry conditions are expected through the period. However, some
guidance is suggesting showers or even a few thunderstorms over
the eastern mountains on Sunday. At this time, probabilities are
very low (15%) but will need to see if chances increase over the
next day or two.

Breezy winds through this evening will decrease through the
weekend, though there will still be some breezy locations
Saturday, especially along the Cascade gaps.

RH values are expected to remain in the 15 to 20 percent range in
many of the lower elevation areas through the weekend.


.LONG TERM...
Monday through Friday...Another weak disturbance/trough moves
across the area on Monday. This system will bring some rain to the
Cascades into Tuesday while the rest of the region remains dry.
Zonal flow then develops into Wednesday, followed by a return to
southwest flow Thursday into Friday. By the end of the extended
period, a large low and trough is approaching the Pacific
Northwest.

Gusty winds are expected to redevelop Monday afternoon and then
again Wednesday and by the end of the week with the approach of
the upper low/trough. Winds will generally gust in the 25 to 35
mph range in the Cascade Gaps, Gorge, portions of the Basin,
Kittitas Valley. On Monday, the NBM probabilities of wind gusts
>=39 mph are generally 50 to 70 percent in these areas and a bit
higher in the Kittitas Valley. On Wednesday, the values are
slightly lower, about 40 to 60 percent.

High temperatures look to be near normal through Wednesday then
about 5 degrees below normal toward the end of the week.

.AVIATION...(Previous Discussion)
18Z TAFS...VFR conditions are expected through the TAF period.
However, due to area wildfires, there could be some smoke impacts
at DLS/PDT/ALW/PSC which could lower VSBYS or CIGS through the
period, but confidence is too low to include in the individual
forecasts at this time.

Breezy winds will continue at all sites except PSC through the
afternoon and evening hours before decreasing. DLS will gust 25 to
30 kts, while the other locations will gust to around 20 kts.
Later this evening/overnight, all sites will decrease to around 10
kts or less. DLS will gust again on Saturday afternoon to around
20 kts.
