Synopsis for southern washington and northern oregon coast.. Low pressure north of the waters weakens today and tonight. Another low pressure system approaches from the northwest Saturday morning, and will bring a frontal system across the waters late Saturday night through Sunday morning. Weak high pressure moves across the waters Monday before the next low moves near or across the waters Monday night and Tuesday.

Synopsis An upper level trough of low pressure will make its way
across the pacific NW through tonight, keeping the region in a cool
and showery air mass. Large waves at the coast will ease later today
with more typical wave heights Saturday. A weak ridge of high
pressure Saturday will temporarily decrease the showers, but then
another system arrives Sunday for more rain and mountain snow. An
active weather pattern continues next week, and it looks like snow
levels will dip down into the lower foothills in the latter half of
the week.

Short term Today through Sunday... The strong low pressure system
which produced the large and dangerous surf Thursday is in the
process of weakening while approaching vancouver island and the
olympic peninsula. Cool, unsettled onshore flow will continue to push
showers across the forecast area through tonight, falling as snow in
the cascades. Small hail will be possible with heavier showers due to
relatively low freezing levels.

The last remnants of the decaying low will move onshore later today
and tonight, bringing a surge in shower activity tonight. With
1000-500 mb thicknesses hovering around 530 dm, snow levels will
generally remain around 2500 feet. With this system weakening as it
moves onshore, orographic lift will be modest in the cascades.

General 3 to 6 inch totals are expected from the snow showers in the
cascades through tonight, which is below advisory criteria. Valley
rain and mountain snow showers are expected to taper off Saturday as
a weak ridge of high pressure moves across the pac nw.

Any lull behind this system will be brief, as our next low pressure
system is already in the process of crossing the gulf of alaska. This
system will push another robust pacific frontal system toward the pac
nw coast, with rain spreading onshore by Sunday morning. 12z and 00z
ecmwf ensembles, 00z uw wrf-gfs, and the 06z NAM all suggest winds
will reach or exceed warning criteria for the coast, though the
easterly component to the pressure gradients will likely keep the
stronger winds confined to the beaches, headlands, and adjacent
coastal waters. Given this good model agreement, we will issue a high
wind watch for the beaches and headlands in all our coastal zones.

This event looks marginal; given latest guidance, 55-65 mph gusts are
most likely for the beaches and headlands. There is still some chance
that a strong pacific jet develops a secondary low along the front
somewhere along the oregon or northern california coast. If this
occurs to our south, it could limit the wind potential for our
forecast area.

The frontal system will be in the process of occluding while moving
onshore Sunday morning. This should keep our cascades from really
getting into this system's warm sector, and precip should fall mainly
as snow for the passes and above. Whether or not an advisory will be
needed for the cascades largely depends on whether or not the system
splits while moving onshore Sunday. The fast progression of this
front will probably limit snow accumulations, with about 3 to 7
inches expected for most of our cascades. Valley rain and mountain
snow showers will persist behind the front, with snow levels
generally around 3000 feet. Weagle

Long term Sunday night through Thursday... By the time the showers
taper off behind Sunday's frontal system, the next large upper low
will be taking shape in the gulf of alaska. This will serve as the
parent low pressure system next week, guiding several waves of low
pressure toward the pac nw. Post-frontal showers on Monday will
likely decrease as weak ridging aloft slides across the pac nw. The
forecast becomes more complicated Tuesday, as an increasing number of
models are involving some southern stream energy with the gulf of
alaska upper trough. There are several possible outcomes depending on
how much phasing occurs between the two systems. The models which
show more phasing (such as the 00z ecmwf) develop a stronger surface
low offshore which then curls north into british columbia. This would
bring a rather typical front through the forecast area, with snow
levels remaining well up into the foothills. Some models and
ensembles show weaker or later phasing, thus a weaker surface low and
a more southern track. If that occurs, snow levels could be
considerably lower as precip moves through on Tuesday. For now, we
favor the 00z ECMWF solution, considering the strong pacific jet
stream and baroclinicity available for rapid cyclogenesis. Just about
all models eventually usher in a much cooler air mass by Thursday as
showers continue. The 00z ECMWF suggestion of -5 to -6 deg c 850 mb
temps would likely result in snow levels dropping down into the lower
foothills, but not quite the lower valley floors. Either way, temps
appear likely to swing to below normal by the middle to latter
portion of next week, with continued unsettled weather across the
pacific northwest. Weagle

Aviation Showers will persist today and tonight for a mix of
vfr and MVFR flight conditions. Gusty southwest winds can be
expected along the coast late this morning through the early
evening. The willamette valley will likely have 20 kt gusts
this afternoon.

Pdx and approaches... Showers will persist today and tonight. Mostly
MVFR conditions this morning. There is a better chance forVFR
conditions this afternoon as a trough moves across the willamette
valley. Could see some 20 kt gusts with the trough passage this
afternoon. ~tj

Marine A low pressure system north of the waters will continue
hazardous seas and gusty winds through Saturday. The seas will
likely remain between 17 and 20 feet through Saturday morning.

The seas will briefly drop to below 15 feet Saturday afternoon
and evening before rebuilding with the next approaching low
Saturday night.

Models have been consistent on forecasting storm force gusts
with the next weather system Saturday night through Sunday
morning, and have issued a storm force watch. There is good model
agreement that the seas will build to above 20 feet late Saturday
night. Models show a dynamic fetch is likely, and have forecasted
the seas slightly higher than the current model forecast. Expect
the seas to peak around 24 feet Sunday morning. The seas will be
choppier this round with dominant wave periods expected to be
around 12 seconds. Seas will subside to below 20 feet Sunday
afternoon, and gradually subside to around 12 feet Monday night
gales are possible with the next frontal system on Tuesday, but
forecast confidence of this system is low due to model
variability on the timing and track of the low. ~tj

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.
