830 pm pdt Sat jul 22 2017

Synopsis A weak upper trough will bring clouds and cooler
weather on Sunday. High pressure aloft will build over the area
Monday and Tuesday for a warming trend. Stronger onshore flow
will cool highs back to near normal Wednesday through Friday.

Short term Low clouds have mostly cleared, even at the coast.

They should fill back in tonight as a weak upper trough swings
through and low level flow increases. Sunday will start out
mostly cloudy. Clouds will linger into the afternoon for many
areas but eventually they will scatter as the upper trough exits
to the east. Highs Sunday will cool several degrees over the
interior - back to near normal.

An upper ridge will build over the area Monday and Tuesday for
sunny days and warmer weather. Highs should be in the 70s at the
coast and mostly in the 80s for the interior. Tuesday looks like
the warmest day for most areas with a marine push beginning
Tuesday night. Schneider

Long term Previous discussion... The overall long-wave pattern
with the upper ridge over the intermountain west and the trough in
the vicinity of 140-150w looks to continue through the rest of
next week. This pattern leaves western washington primarily in a
sw flow aloft. The progs concur on a sequence of weak shortwaves
rotating out of the offshore long-wave trough with the first
arriving Tuesday night and Wednesday. Heights aloft decline and
low level onshore flow increases for another surge inland of
marine clouds with moderating high temperatures.

Guidance continues to hint at the possibility of convection near the
cascade crest Wednesday night. Upon collaboration with neighboring
forecast offices, will increase a threat of thunderstorms there.

Progs differ on timing, but a few more ejecting shortwaves should
maintain low level onshore flow into Thursday and Friday for more of
the morning cloud afternoon Sun regime with close to seasonal
temperatures. The coming weekend may offer the start of a warming
trend as heights aloft rise. No rain is in sight, so the dry streak
in seattle on day 35 today looks to extend through at least the
coming week. Buehner

Aviation Westerly flow aloft over western washington this
evening will continue tonight and Sunday, as the broad upper
ridge over the area shifts east and a weak upper trough moves over
the region. At the surface, onshore flow will continue with high
pressure offshore and lower pressure inland. The air mass is
stable.

There is no significant cloud cover over western washington this
evening. Low level moisture will increase tonight though, with
widespread low-end MVFR and local ifr ceilings likely beginning
09z-12z most areas. Gradual improvement is expected Sunday
afternoon, with widespreadVFR conditions late in the afternoon.

Ksea... Low clouds will likely move inland or develop over the area
late tonight, with ceilings 010-015 likely from roughly 12z
through 20z. Northerly wind 7-13 kt easing to 5-10 kt around
midnight. Mcdonnal

Marine Varying amount of onshore flow will prevail for the next
several days with high pressure offshore and lower pressure inland.

The central and eastern strait of juan de fuca should have small
craft advisory west winds most evenings, and gale force winds are
possible there Tuesday evening. The coastal waters will also have
small craft advisory northwest winds at times for the next few
days, especially the outer waters. Mcdonnal
