Synopsis for southern washington and northern oregon coast.. A low pres center around 47n/129w this morning will continue to strengthen and move ne today. The low is expected to move ashore near vancouver island later this morning. A slow-moving frontal boundary will reside over the waters this morning before pushing onshore. A secondary cold front moves through the waters this evening. High pres builds tonight and Thu then holds over the waters Fri. A weak front will move across the waters Saturday morning.

Synopsis A warm front is moving east across the region this
morning, with a cold front following and moving southeast through sw
washington and NW oregon later today. This will turn the rain into
showers later today, then showers will continue into Thu as an upper
level trough of low pressure moves across the pacific nw. Fri is
expected to be dry as high pres moves across the region, then
chances for rain return for the weekend as the next system moves in.

Short term This afternoon through Friday... Radar this morning
shows rain associated with a warm front moving across the area. The
front is moving a little bit faster than originally thought, with
the back edge of precip shown stretching from about troutdale south
to the linn county cascade foothills and then west to about newport.

Areas north and west of the line will generally see a break in rain
for the rest of the morning before some showers develop this
afternoon. However, after this morning outside of the cascades, it's
not looking like today will be much of a soaker. For those keeping
track, it's becoming less likely that pdx will break its march
rainfall record.

The parent surface low off the wa coast is expected to lift NE across
vancouver island today. A cold front trailing the low will push
southeast across the forecast area today, slowing as becomes more
parallel to the upper flow late today. With
deep moisture in the air mass preceding the cold front, some
additional rain, turning showery behind the front, with low level
flow turning sharply to the northwest. The trailing upper level
trough is expected to move across Thu morning, with moisture will
generally be limited to low levels below about 10k feet. Once the
upper trough passes, shower activity is expected to become more
reliant on orographic lift and thus will tend to become more tied to
the upwind side of the mountains.

Thu night into Fri a ridge of high pres at the surface and aloft
pushes east into western oregon and washington. Subsidence will
stabilize the atmosphere bringing an end to the showers. Low level
will be slow to dry out though as a low level offshore flow never
really gets going. Added some patchy fog to the forecast for Friday
morning, particularly away from the coast where there may be some
offshore drift that prevents it. Bowen

Long term Friday night through Tuesday... No changes. Previous
discussion follows. Model agreement is better through sat,
with a more progressive pattern over the region. Models continue to
show ridging east of the region on Saturday. Still looks dry and mild
on Saturday, with just increasing mid and high clouds. Now, while
there are still differences in the models, will have to keep some
minor threat of showers in forecast for Sat night into early next

Aviation Conditions are bouncing betweenVFR and MVFR at most
taf sites and will continue for most of the day today. Heaviest
ran has now shifted south of salem, but areas along the coast are
experiencing heavy drizzle which is reducing visibilities at or
below 2sm.

Pdx and approaches... Mix of MVFR andVFR conditions through the
remainder of the day. Heaviest rain has now shifted south of the
region which should limit any visibility restriction. Only
exception will be if lower visibilities from drizzle at the coast
makes it into the valley. This is a low probability and the most
likely scenario is p6sm visibilities and MVFR orVFR ceilings.


Marine A surface low pres is currently centered around
47n/129w. This low will move NE and onshore on vancouver island
later this morning. Southerly winds associated with this low have
picked up overnight, and we are now seeing borderline gale force
winds at buoy 46050. Expect winds generally 25 to 30 kt with
gusts to 35 kt through mid-morning. There may be a few gusts to
40 kt south of cascade head and within 20 nm of shore as some
coastal jet enhancement may occur. Winds will become w-nw and
slacken later this morning and especially this afternoon as the
cold front moves onshore.

Higher pres will become established over the NE pac later tonight
and thu, and will remain through fri. There may be some
borderline small craft advisory NW winds over the northern
waters later tonight into Thu morning. But otherwise, expect
fairly benign conditions during this time. A weak front will move
through the waters sat, which will briefly turn the winds
southerly and may bring some gusts of 20 to 25 kt. Northerly
winds return Sun and Mon and may be gusty at times.

Seas will remain in the 12 to 14 ft range through tonight. Long
period westerly swell will combine with a significant southerly
wind wave component to produce chaotic seas. The seas will
subside tonight and thu, dropping below 10 ft by around midnight.

Seas then remain below 10 ft through the next several days. Pyle

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
