Synopsis A dry weather pattern with areas of 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 The last clouds evaporated over the last few hours and
western washington is mostly clear this morning. There is patchy
fog. Temperatures are mostly in the 40s with some 30s--freezing
temperatures are not yet here. Today will be sunny after the areas
of fog clear. Highs will be in the low to mid 50s. With a northerly
breeze through the puget trough it may seem chillier.

A sharp upper ridge off the coast this morning will slowly move
inland through Monday. This will keep skies clear. Areas of fog will
form each night and linger in the mornings. High temperatures will be
in the low to mid 50s each day. The next two nights are going to be
cool, with lows in the 30s and upper 20s. Some of the fog will be
freezing fog. Meanwhile the mountains will remain sunny, with
the freezing level 10,000 feet or higher. Burke

Long term Tuesday looks like the last dry day for awhile. A
weather system will approach the coast during the day, and clouds
will increase across the area. Highs on Tuesday will again be in
the low to mid 50s. The GFS and euro differ slightly about when the
rain will begin, with the euro a bit slower. It does seem rain will
start some time on Wednesday, so have kept the forecast of rain
likely for Wednesday.

Model timing varies quite a bit after that, and so do the forecast
tracks of the various fronts, with the euro sending most of the
energy into oregon and the GFS moving the fronts right through
washington. For now a the forecast is for rain at times, with high
pops but relatively low qpf, and there will be some dry periods
between fronts. Highs will be somewhat lower than what we have been
experiencing, mostly in the 45 to 50 range. The snow level will fall
to 4000 to 5000 feet, which means most ski areas and passes will get
snow at times. Burke

Aviation Northerly flow aloft will continue through this
afternoon as an upper level ridge moves onshore. Low level flow will
also be northerly. MainlyVFR CIGS under clear skies at this hour,
other than localized areas of lingering low clouds. Some lowering to
MVFR CIGS is possible into the morning hours where low clouds
develop, though widespread low clouds are not expected. Some patchy
fog is possible as well leading isolated lifr vsbys, but expect it
to be mainly limited to fog-prone areas as northerly wind speeds
range from 5-15 knots. Clear skies tomorrow night into Sunday will
lend to more widespread fog development.

Ksea... Few lingering low clouds exist, but the majority of cloud
shield has broken apart.VFR CIGS should continue through the
morning hours. There is a slight possibility for MVFR CIGS due to
low clouds (mainly 12z-17z), though confidence is not high of their
formation. Otherwise, clear skies will prevail into the afternoon
and overnight. Northerly winds near 10 kts will continue thru the
taf period.

There may be a period of llws during the morning hours, possibly
continuing into the early afternoon. Sfc winds will be northerly
with winds just above sfc out of the east around 15 knots. Jd

Marine High pressure over british columbia with lower pressure
over southwest oregon will result in northerly flow today. The flow
will become easterly tonight as higher pressure builds east of the
cascades while lower pressure prevails over the coastal waters.

Easterly (offshore) flow will then persist through Monday.

Anticipate an active pattern to develop about the middle of next
week, leading to the possibility of gale force southerlies over the
coastal waters next Wednesday.

Hydrology River flooding is unlikely over the next seven days.

Sew watches warnings advisories
Wa... None.

Pz... Small craft advisory until 4 pm pst this afternoon for coastal
waters from CAPE flattery to james island out 10 nm-
northern inland waters including the san juan islands.

Small craft advisory until 5 pm pst this afternoon for puget
sound and hood canal.

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.
