Synopsis A surface ridge offshore will maintain onshore flow
across western washington into early next week. This will produce
typical early summer weather with mild temperatures and morning low
clouds and afternoon sunshine. An upper level ridge will weaken the
onshore flow and produce a minor warming trend Thursday and Friday.

Stronger onshore flow will bring a bit more cloud cover this
weekend. A weak front could bring a few showers to mainly the coast
on Sunday.

Short term Satellite imagery shows mostly clear skies across W wa
this evening except for low marine stratus that has pushed inland
along the central wa coast. Onshore pressure gradients are around
1.5 mb. This will help recharge the already somewhat moist marine
layer over the interior tonight, so Wednesday morning should start
off with our familiar low stratus clouds covering most of the
interior lowlands. Burn-off should occur around midday again
followed by mostly sunny skies Wednesday afternoon.

An upper level ridge offshore along 135w this evening will move
steadily eastward, with the axis reaching the offshore waters on
Thursday then moving slowly across wa on Friday. The ridge will
weaken the onshore flow for less morning cloud cover Thursday and
especially on Friday. More sunshine coupled with warming from the
ridge will bring a minor warming trend. Inland high temperatures
should be in the 70s on Thursday and in the mid 70s to lower 80s on
Friday. Coastal highs will be cooler, 60s on Thursday with some
lower 70s around on Friday. Kam

Long term The upper level ridge will exit over the id panhandle
Friday night leaving the way clear for a weak front to approach the
region this weekend. Onshore flow will increase again Friday night
which will produce more stratus and a deeper marine layer Saturday
morning. High temperatures will drop back into the 70s. The weak
front approaching the coast will slide inland on Sunday. There is a
slight chance for some spotty showers along the coast and maybe the
north interior. The marine layer will be pretty deep but this could
allow some intermittent sunbreaks to occur in the afternoon.

The onshore flow pattern will continue early next week with a
surface ridge offshore and moderate W flow aloft over the region. So
independence day will have the familiar morning low clouds with some
afternoon clearing and mild temperatures. Kam

Aviation Weak upper level trof over the region will cont moving
slowly e, with upper level ridge following in its wake. Contd nw
flow aloft. The low level flow will remain onshore. Areas of coastal
marine stratus should spread back inland overnight but Wednesday
should see a bit less of the stratus and it should burn off a bit
quicker.

Ksea... Morning low clouds from about 12-18z are a pretty good bet
again Wednesday morning--although oth-sea is only +2mb and yesterday
at this time it was +4mb, so I may trim it back a bit and it could
be that a four hour tempo group might be enough to cover it on wed.

Marine Higher pres offshore with lower pres E of the cascades
will maintain onshore flow of varying strength through this weekend.

The flow will become strong Friday afternoon and evening for the
possibility of gale force winds over parts of the strait of juan de
fuca.

Sew watches warnings advisories
Wa... None.

Pz... Small craft advisories central eastern strait of juan de fuca.

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.
