Synopsis for the northern and central washington coastal and inland waters..High pressure over the pacific will build east tonight and Saturday. This will increase an easterly offshore flow tonight and this weekend. Initially strong, the winds will weaken by early Saturday and remain offshore this weekend. The weather will be quiet for several days with the high pressure and no marine weather concerns. By mid-week, potentially the next system with impact for the region will begin to push in from the west.

Synopsis A dry weather pattern with patchy night and
morning fog will persist into early next week. Overnight
temperatures will be on the cooler side, dropping into the 30s and
even upper 20s by Sunday morning at some locations. A weather system
will bring wet weather back by mid to late next week.

Short term Skies have generally cleared over the northern third
of the area this afternoon, with clearing to continue to spread
southward this evening. The upper level ridge along 135w will
continue to build over the coastal waters tonight. Clear skies will
help low temperatures dip into the 30s tonight, with near freezing
temperatures in the far north. Patchy morning fog - with some
freezing fog - Saturday will burn off to sunny skies and near normal
temperatures in the low 50s. Overnight temperatures Saturday night
into Sunday morning at some locations will dip into the upper 20s.

Morning fog will return again Sunday with clearing with high
temperatures rising a bit over Saturdays temperatures, especially
through the eastern interior lowlands. The upper level ridge will
shift onshore Sunday, with low level flow remaining offshore.

Long term Medium range models remain in general agreement
through midweek. The upper level ridge will linger over the region
Monday and Tuesday, keeping conditions dry. Monday will be mostly
sunny while a weak weather system tries and fails to make much
headway against the ridge. Increasing clouds Tuesday, but dry with
high temperatures in the low to mid 50s. Models continue to show a
weather system affecting the area Wednesday, with rain reaching the
coast early Wednesday morning, followed by a second impulse during
the day Thursday followed by a showery pattern into Friday.

Aviation Clearing has been slow and steady today from north to
south in the wake of a weak trough of low pressure that swung
through the area. A few spotty sprinkles remain in the far south but
by and large, it is not dry with sailings and visibilities
continuing to improve. Return toVFR conditions is expected at all
terminals by 22z. Overnight with clear skies and generally light
northerly winds less than 10 kts, there will be some patchy fog in
the more fog prone and favored spots, although northerly winds will
bring in dry advection that may limit the overall coverage of fog.

Saturday will be aVFR day with a ridge of high pressure building in
and winds remaining dry and offshore.

Ksea... Northerly winds around 10 kts this afternoon at the terminal
should persist through the evening before lightening up slightly
into the 6-8 knot range and shift to northeasterly. Lingering low
clouds will be dissipated by 00z andVFR conditions are expected.

While some patchy fog is possible tonight with the clear skies,
confidence is low in exactly where it might be, so will not carry
explicit mention of lower CIGS vsby in current TAF but will continue
to hint at the possibility. Northeasterly winds will be drying the
air over the area so fog should not be widespread. Saturday looks
vfr with mainly clear skies and northeast, offshore winds, as a
ridge of high pressure builds atop the region. Johnson

Marine A ridge of high pressure over the pacific will build east
overnight and into Saturday, in the wake of today's weak and
departing low pressure. Some small craft advisory level winds will
continue in the straight and northern inland waters through about 6
am Saturday. This was extended ever so slightly given the current
model forecasts which show the elevated wind speeds lasting a little
longer, with offshore flow increasing as the high builds in
strongly. This will then bring several days of clear and calm
weather through mid-week. Next weather system will approach by wed-
thu and turn winds more southerly again and increase the speeds.

Johnson
hydrology... Models are indicating a rainy period to start up midweek
through the end of next week. This would drive rivers up sharply.

But so far, no river flooding looks likely through the next seven
days.

Sew watches warnings advisories
A... None.

Pz... Small craft advisory from 7 pm this evening to 6 am pst Saturday
for central u.S. Waters strait of juan de fuca-coastal

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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
