Synopsis Areas of morning low clouds will burn off to sunshine
through Sunday. The upper ridge over the western united states will
shift closer to the pacific northwest with rather warm temperatures
possible by around Tuesday of next week.

Short term A weak upper trough is fading away and morning marine
layer clouds will burn off through midday. Upper heights over the
area will rise into the weekend as the upper ridge bulges a little
toward the area. There are still likely to some morning low clouds
and fog patches through the weekend, maybe less of that on Saturday
but more on Sunday, but it could go either way and temps wont change
much til next week.

Long term The strong upper ridge over the western u.S. Will bulge
into the area. Thermal low pressure will probably stay east of the
cascades--keeping low level flow weakly onshore, but highs should
get well into the 80s, and maybe the lower 90s for the warmer spots.

The sea breeze will likely keep highs at the coast in the 70s.

Aviation A weak upper trough will skirt the region today.

Generally light west to northwesterly flow aloft. Air mass moist in
the lower levels due to onshore flow and dry in the mid upper
levels. Atmosphere stable.

Satellite imagery shows marine clouds beginning to break up with
some partial spots of clearing at 16z. Areas of residual MVFR cigs
mainly around 2500 ft should lift and clear by 18-19z. Onshore flow
through Saturday will probably allow for some MVFR status to form
later tonight and early Saturday morning, but more limited in
coverage with a faster burn off.

Ksea... Satellite imagery shows the terminal on the edge of a 2500 ft
ceiling and partial clearing to the east. There may be a couple of
hours through 18z with periods of MVFR and also sunbreaks as the
clouds gradually dissipate.VFR should prevail by 18z. The potential
for stratus Saturday morning is less than today but MVFR is still
possible. Will leave a scatter 2500 ft cig in the TAF until more
model date can be evaluated. Dtm

Marine Onshore flow will begin to weaken on Sunday with generally
light northerly flow by Monday and Tuesday. Northwesterly winds may
reach small craft strength over the coastal waters early next week.

Typical westerly winds in the central and eastern strait could bring
small craft winds or gales, mainly during the afternoon and evening
hours through at least Saturday night. More typical diurnal winds in
the strait Sunday through Tuesday could still produce small craft
westerlies during the evening hours. Dtm

Sew watches warnings advisories
Wa... None.

Pz... Gale warning from 5 pm pdt today through midnight tonight
for the central u.S. Waters strait of juan de fuca-east
entrance u.S. Waters strait of juan de fuca.

Small craft advisory until 5 pm pdt today for the central
u.S. Waters strait of juan de fuca-east entrance u.S. Waters
strait of juan de fuca.

Small craft advisory from 5 pm this afternoon to midnight
tonight for admiralty inlet-northern inland waters

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
