Synopsis Clouds will continue to burn off through evening and
then redevelop overnight. Friday will have areas of morning clouds
then afternoon Sun and warmer temperatures. The weekend will have
sunny skies and warmer temperatures. A warming trend should continue
into next week and the morning low clouds and fog should be mainly
confined to the coast and around the strait of juan de fuca.

Short term Areas that have clouds in the lowlands should see
clearing through evening and then the clouds will redevelop
overnight--but Friday will see the clouds break out faster and it
will be warmer. Saturday should be sunny with just some shallow
marine layer clouds--mainly just on the coast and in the strait of
juan de fuca in the morning. Sunday might have a little more
marine air, but temps only falling off a touch. 500mb heights will
be up around 588 dam over the weekend and 850mb temps will be around
15c over puget sound so we should be back to the weather we had the
past few days.

Long term The air mass should warm into early next week, with
possibly Tuesday being the warmest day, but it is a little early to
say if the ridge will peak one day or the next. Highs should get
well into the 80s, maybe around 90 in the warmer spots--but not near
the coast. Gradients will continue to give a pretty good sea breeze
and thermal low pressure will remain east of the cascades, so the
coast will probably just stay in the 70s.

Aviation An upper trough over the area will weaken tonight and
Friday with westerly flow aloft. At the surface, high pressure
will be offshore with lower pressure inland. The air mass is
stable.

MVFR low clouds will continue to thin and eventually scatter later
this afternoon or early this evening. MVFR low clouds will
redevelop later tonight for most areas.

Ksea... MVFR low clouds should thin and scatter in the next couple of
hours. MVFR low clouds are expected to redevelop late tonight.

Southwest wind 4-8 knots will become northerly this evening.

Schneider

Marine Onshore flow will continue for the next several days
with high pressure offshore and lower pressure inland. Expect
at least small craft advisory west winds each night in the
central and eastern strait of juan de fuca. Gales cannot be
completely ruled out the next few evenings in the strait but it
looks marginal each day. Schneider

Sew watches warnings advisories
Wa... None.

Pz... Small craft advisory until 5 am pdt Friday for 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 5 am pdt Friday
for northern inland waters including the san juan islands.

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.
