Synopsis High pressure aloft will maintain cool dry weather
through Tuesday. Patchy night and morning fog or freezing fog will
give way to afternoon sunshine with highs reaching into the low to
mid 50s. A series of low pressure systems will bring wet weather
beginning Wednesday and continuing through the weekend.

Short term A sharp upper ridge axis is right over western
washington this morning. Surface gradients are light offshore.

Satellite imagery shows a mass of low clouds well off the coast, as
well as areas of fog over the land, especially the southwest
interior. Today will be like the last couple of days, with sunny
weather after some morning fog. Highs will be in the low to mid 50s.

The freezing level in the mountains is around 10,000 feet.

The upper ridge will move east Tuesday, giving southerly flow aloft
over western washington, and allowing clouds from an approaching
weather system to leak into the area. Models have slowed this system
slightly, so most inland areas will probably still have partly sunny
skies Tuesday afternoon. The coast and olympics will become cloudy,
though. Any rain will hold off until Tuesday night. Highs will again
be in the low to mid 50s.

Rain will develop on the coast Tuesday night, then spread inland on
Wednesday. By Wednesday afternoon rain is likely nearly everywhere,
and it should definitely be raining Wednesday night. This
system has to push through strong high pressure, so a low qpf
event is expected. Precipitation amounts will be several tenths of
an inch in the mountains, with perhaps half that over the lowlands.

Highs will be in the low 50s. The snow level will fall to 4000 feet
or so Wednesday night, but with the low qpf, there will probably be
only a few inches of snow in the passes. Burke

Long term Models have been consistent in showing another, wetter
system arriving Thursday, followed by an upper trough for showers
Friday. High temperatures will fall to around 50 on Thursday and
into the upper 40s on Friday. The snow level will fall to around
3000 feet on Friday. During the wettest period, about 18z Thursday
to 18z Friday, several inches of snow are likely in the passes--
possibly even advisory amounts.

Models diverge somewhat after Friday. The GFS brings another system
into the region Saturday, while the latest euro run builds a ridge
and is pretty dry both Saturday and Sunday. For now have disregarded
that solution and kept likely pops Saturday with chance pops Sunday.

Highs both days will be 45-50, with lows around 40--pretty close to
average for this time of year. Burke

Aviation Upper ridge axis over western washington this morning
will shift east of the cascades today with increasing south to
southwest flow aloft. The air mass remains dry and stable except for
some patchy low level moisture. Low level flow is still offshore,
but weaker than 24 hours ago. This has allowed some patchy fog to
develop. This should burn off by late morning, but will likely
redevelop again Tuesday morning.

Ksea...VFR. May see patchy shallow fog in the vicinity early this
morning. Surface winds light and variable becoming northerly 5 to 10
knots in the afternoon. 27

Marine High pressure over id with lower pressure over the wa
coastal waters will keep the flow mainly easterly through Tuesday.

Expect a weakening cold front to approach from the west Tuesday
night. This front will probably dissipate before reaching the coast
late Wednesday.

A stronger frontal system may impact the area the latter part of the
workweek. Confidence in the forecast beyond Wednesday was low
because of lack of consistency in and agreement between the weather
models. After collaboration with adjacent marine forecast offices,
we decided to stick with the stronger solution for now in regards to
wind speeds. However, we also chose to not bite off on the 20+ foot
waves being forecast for the central wa coastal waters on Friday.

There is a good chance that this will disappear in the next wave
model run or cycle.

Hydrology River flooding is unlikely over the next seven days.

Sew watches warnings advisories
Wa... None.

Pz... None.

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.
