Synopsis An upper ridge will bring dry weather with a warming
trend through the weekend. The ridge will shift inland early next
week with onshore flow developing for a return to more seasonable
temperatures and some night and morning clouds.

Short term An upper ridge will build over the area through
Saturday. At the same time, low level onshore flow will be
northerly or even slightly offshore as a thermal trough pushes
north up the coast. This will result in sunny weather Friday and
Saturday with a warming trend. Highs will be in 70s to lower 80s
Friday and in the 80s to near 90 on Saturday.

The upper ridge axis will shift over eastern washington on Sunday
and weak onshore flow will begin to develop later in the day as a
thermal trough over the coast shifts inland. It will be another
very warm day for the interior - likely the warmest of the season
so far - with highs in the mid 80s to mid 90s. The coast should
start to see some cooling as onshore breezes kick in during the
afternoon although the amount of cooling is a bit uncertain for
now. Schneider

Long term Previous discussion... The long-wave upper ridge axis
shifts east of the area Sunday night and Monday. Many models are
rather robust in shifting pressure gradients onshore as the ridge
moves eastward Sunday evening, resulting in significant cooling on
Monday. However, there is the hint of a short wave ridge offshore
at the mid levels that would only result in a partial marine push
Sunday night, with a more significant one Monday evening. Our
current forecast reflects the latter scenario and results in
cooling for Monday, but still warm in the puget sound area and
near the cascades.

After a stronger marine push on Monday, a weak trough of low
pressure aloft combined with moderate onshore flow will result in
night and morning clouds and temperatures near to slightly below
average Tuesday onward. Albrecht

Aviation A strong upper ridge axis will slowly move from its
current position near 135w to east of 130w on Friday evening.

Moderate northwest flow aloft will weaken a bit on Friday. The air
mass will be dry and stable, with clear skies prevailing.

Ksea... Clear skies and north flow for the next 30 hours. Haner

Marine A northeast-southwest oriented surface ridge will
remain over the pacific through Saturday. Meanwhile, a strong heat
low over california and southern oregon will set up northerly
gradients over the waters. Winds over the coastal waters are
following a diurnal cycle, with northerlies peaking during the
late afternoon and evening, then falling off during the morning.

This cycle will repeat itself on Friday and Saturday. Gradients
will weaken on Sunday, then onshore flow will quickly increase on
Sunday night. Haner

Sew watches warnings advisories
Wa... 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.
