Synopsis Showers will diminish across the area today behind a
departing frontal system. High pressure aloft will bring drier
weather to the region Thursday into early next week. A couple of
very weak weather systems will bring a chance of showers to mainly
the coast and northern cascades Thursday night and again on
Sunday.

Short term today through Friday The front that brought a few
hours of moderate to locally heavy precipitation to the region is
now well east of the cascades this morning with the trailing upper
trough now crossing the area. This will keep some shower activity
going this morning, but it will diminish as the day progresses. By
evening, any remaining showers will likely be confined to the
cascades. Despite persistent cloud cover, daytime temperatures
will be remain a little above seasonal normals.

A dirty upper ridge will begin to build into the region tonight.

Light surface gradients and considerable low level moisture spell
a rather grey but reasonably dry day for western washington on
Thursday. A weak weather system passing over the top of the
building ridge offshore looks to bring a chance of a shower to
coastal areas and the cascades Thursday night. After that, the
ridge continues to gain some amplitude on Friday. There will still
be a lot of low level moisture around on Friday, but there could
be a few peeks of Sun late in the day. High temperatures in the
lowlands on both Thursday and Friday will be near 50 with lows
generally mid 30s to lower 40s.

Long term Saturday through Tuesday Models remain in good
agreement with the idea of the upper ridge axis shifting onshore
and flattening somewhat on Saturday in response to a weather
system moving into british columbia. This same weather system
retrogrades the ridge offshore and clips the northern part of the
forecast area. At this point, the best chance of any precipitation
appears to be in the north cascades with dry conditions for the
remainder of the region. By early next week, the upper ridge axis
shifts offshore with strong surface ridging taken up residence in
the interior of british columbia. This looks like the set up for
more dry weather, but lowering temperatures as some colder air
filters out of the fraser river valley. 27

Aviation An upper ridge will build over the area today and
tonight with northwest flow aloft. At the surface, onshore flow
will ease this morning and become light this afternoon and
evening. The air mass is moist and stable.

Lots of low clouds today and tonight. A broad and disorganized
puget sound convergence zone over northern king county will sag
south and break up this morning and early afternoon.

Ksea... Low clouds today and tonight. Northwest wind 4-8 knots will
become light this afternoon and evening. Schneider

Marine Northwesterly onshore flow will ease today and become
relatively light tonight and Thursday as weak high pressure moves
over the area. 10-13 foot west swell over the coastal waters will
subside below 10 feet Thursday morning.

Weak high pressure will remain over the area Friday and Saturday
for relatively light winds. Northerly offshore flow will develop
on Sunday as high pressure builds over british columbia.

A coastal flood advisory is in effect this morning for the low
lying areas around the inland waters due to high astronomical
tides and tidal anomalies. It looks like a marginal event at most
based on current observations. Tides will be high again Thursday
morning but atmospheric pressures will be higher which should
preclude any additional coastal flooding. Schneider

Hydrology The skokomish river in mason county is cresting now
at minor flood stage this morning and the flood warning remains in
effect. The river will recede this afternoon and evening. Beyond
that, river flooding is not anticipated over the next 7 days.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

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