Synopsis for the northern and central washington coastal and inland waters..High pressure offshore along with lowering pressure east of the cascades will result in strengthening onshore flow over the next few days. This will lead to the potential for gale force winds over parts of the strait of juan de fuca at times tonight through Tuesday. Small craft winds could also develop at times over other interior waters.

Synopsis An upper ridge will shift inland through memorial day.

Onshore flow will increase Monday and Tuesday and coastal marine
layer low clouds will push farther inland each morning. An upper
trough and southerly flow aloft will bring an increasing chance of
showers and a few thunderstorms by Tuesday night. Weak weather
disturbances will keep clouds and a chance of showers in the forecast
through the end of next week.

Short term The coastal marine low clouds and patchy fog will
push in a bit farther Monday morning. After areas of morning low
clouds and patchy fog, most of western washington will still be
mostly sunny--just a bit cooler. The coast wont see much change,
still cloudy and chilly along the ocean beaches. An upper shortwave
trough will reach the area Tuesday afternoon and evening--that will
further deepen the marine layer and touch off some showers as well
--marking the end of the dry streak and finishing off the warm spell.

Long term The rest of the week will probably see western wa in
a regime of deep marine layer clouds that break out in the afternoon
and evening. There is a chance or slight chance of showers each day
but the forecast is fairly meaningless and the differences in timing
of weak shortwaves makes it impossible to say which days have the
best chance of being decent and which will be gloomier. One way it
often turns out is with some areas of morning drizzle and then late
afternoon sunbreaks. The pscz area is obviously a likely place to
see drippy weather this time of year with weak shortwaves and
middling heights. In the gfs, upper level heights do recover a bit
around the end of the week, so perhaps Friday and Saturday will be
decent days before an upper trough moves into the northeast pacific
early the following week. And then there is the ECMWF which is cool
and showery as an upper low moves over the area by next Saturday. A
period of sunny weather with above normal temps like we have seen
this weekend is not at all likely for some time based on the global
models I see today.

Aviation An upper level ridge of high pressure will slowly shift
eastward over the northern great basin on Monday. Light onshore flow
will gradually increase through Monday, then become strong onshore
Tuesday. Meanwhile, areas of ifr stratus and fog near the coast and
in the strait will push further inland late tonight and Monday
morning, likely reaching the ksea terminal and possible the kbfi and
kpae terminals in addition to khqm, kclm, and kolm. This should
again mostly burn off by midday, except perhaps continuing at khqm
through the day. It will become slightly unstable this evening and
again Monday afternoon evening with towering cumulus over the
cascades. Thunderstorms are not expected to affect any terminals
through Monday afternoon.

Ksea...VFR with light northerly winds through this evening.

Northwest winds 5 to 9 kt, then light south wind to 5k after 10z.

Ifr stratus still appears likely between 11-17z Monday morning, then
quickly burning off by midday.

Marine High pressure offshore along with lowering pressure east
of the cascades will result in strengthening onshore flow through
Tuesday. This will lead to the potential for gale force winds over
parts of the strait of juan de fuca tonight, and late Monday and
Tuesday afternoon and evening. Gale force winds appear likely
tonight with a gale warning in effect but there is some uncertainty
in the timing. It could happen as early as 7 pm pdt tonight or as
late as midnight Monday. Small craft winds will prevail in the the
strait through Tuesday, possibly reaching gale or near gale force
during the evening and overnight hours. Small craft winds are also
possible in waters adjacent to the east entrance to the strait as
well as the west entrance.

A strong marine push on Tuesday could potentially bring more
widespread small craft winds to other interior waters including
puget sound. Winds may pick up suddenly as the marine push develops.

There is also a threat of thunderstorms Tuesday. Forecasts should be
monitored. Dtm

Sew watches warnings advisories
Wa... None.

Pz... Small craft advisories are in effect for the strait of juan de
fuca, northern inland waters, and admiralty inlet.

Gale warning in effect from this evening through late tonight for
the central and eastern strait of juan de fuca beginning at 6 pm.

Gale watch central and eastern strait Monday night.
