901 am pdt Mon may 22 2017

Synopsis Warmest days of the year for most places today with an
upper level ridge over the area. Strong onshore flow will develop
on Tuesday with an upper level trough rapidly moving toward
western washington spreading clouds into the area and bringing
cooler conditions. The upper trough will weaken and shift east
Thursday and an upper ridge will arrive next weekend.

Short term Today will be several degrees warmer than yesterday
as an upper ridge crosses the area. Highs will be mostly in the
70s coast, strait, and northern interior near the water and in the
80s elsewhere. A few record highs are possible. Mostly sunny
weather will prevail with thin high clouds at times.

The upper ridge will shift inland tonight with upper heights
beginning to fall across the region. Low clouds could reach the
coast tonight which is a little faster than currently advertised.

An upper trough will move over the pacific northwest on Tuesday.

This will induce a strong onshore push. The coast should be mostly
cloudy but the interior looks mostly sunny again on Tuesday. The
main impact from the onshore push will be too cool high temperatures
10-15 degrees on Tuesday. There will also be some windy conditions
for a few hours over the admiralty inlet area late Tuesday
afternoon and into the evening as strong west winds develop. It
looks like at least a wind advisory will be needed to for this.

An upper trough and low level onshore flow will keep things mostly
cloudy on Wednesday. There could be a few showers but nothing
significant. Highs will cool to near normal. Schneider

Long term Previous discussion... Extended models in pretty good
agreement this morning with the upper level trough over the area
on Thursday and the trough moving east Friday. Upper level ridge
offshore building into western washington for the holiday weekend.

Chance of showers on Thursday with the shower chances confined to
the cascades on Friday. Have taken the chance of showers out of
the forecast for cascades on Saturday. Extended models are
trending toward a stronger ridge Friday through the holiday
weekend. If the trend continues look for the chance of showers to
get taken out of the forecast for the lowlands on Thursday. High
temperatures will slowly warm through the period from 60s and
lower 70s on Thursday to upper 60s to near 80 by Sunday. Felton

Aviation An upper level ridge will remain over W wa today then
drift E tonight. A surface ridge just offshore will maintain weak
to moderate low level onshore flow. The air mass will remain dry
through tonight with goodVFR conditions and only high clouds
overhead.

An upper level shortwave trough approaching from the NW will
trigger a marine push with strong onshore flow developing Tuesday
morning and persisting through Tuesday night, particularly
through the strait of juan de fuca. The marine push will spread
low stratus clouds across the wa coast and through the strait for
areas of ifr conditions.

Ksea... GoodVFR today and tonight with just high clouds. Surface
winds will remain northerly 4-10 kt. Kam

Marine A surface ridge just offshore will maintain weak onshore
flow through this afternoon, becoming moderate tonight. Sca
conditions are expected to develop in the central and E strait of
juan de fuca later this evening, then persisting into Tuesday
morning.

An upper level trough approaching from the NW will trigger a very
strong marine push on Tuesday, with very strong W winds
developing through the strait of juan de fuca. Gale force winds
are expected to develop through the strait probably before midday
Tuesday. Peak winds are expected to reach 35-45 kt. However, the
06z canadian mesoscale model indicates there could be an hour or
two of storm force winds in the central and E strait late Tuesday
afternoon or early Tuesday evening.

Gale force winds are also expected to spread over adjacent waters
in the north interior and admiralty inlet Tuesday evening and
possibly Tuesday afternoon.

Onshore flow should begin weakening by late Tuesday night.

However, weaker onshore flow will persist Wednesday through
Friday.

A steep fresh swell will develop off vancouver island and push
into the coastal waters later Tuesday into Wednesday. Kam

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
