Synopsis for southern washington and northern oregon coast.. A 985 mb low off the b.c. Coast has spread a cold front into the coastal waters that will stall over the waters for a while tonight before moving onshore Wed. A secondary cold front is expected to move onshore late Wed and Wed evening, with another early Thu as a possible sub 1000 mb low moves onshore near the columbia river Thu morning. Higher pres will slow build into the waters from the S on Fri, then another strong low is expected t move in from the sw on Fri night and Sat for more at least gale force winds and high seas.

Synopsis Low pressure moving into british columbia will push a
cold front slowly across western washington and oregon tonight
through early Wednesday. This system will spread plenty of rain
across the forecast area, with snow in the cascades. Strong south
winds along the coast will ease this evening. Rain will slowly
taper to showers and isolated thunderstorms Wednesday and linger
through Thursday. Snow levels will lower to the foothills Thursday
and Friday as a cold upper trough crosses the area. Another strong
system may bring more rain, wind, and cascades snow this weekend.

Short term Tonight through Friday... Forecast is generally
tracking well from the morning package. Snow levels have risen as an
upper low well offshore is lifting the baroclinic band and the
southern warmer side of the jet north. Snow levels are currently
around 6000 feet across the lane cascades and 4500-5000 feet across
the northern oregon cascades. Temperatures and snow levels are
certainly rising for the western part of the south washington
cascades zone with snow levels likely around 5000-5500 feet near mt
st helens. The eastern part of that zone and the upper hood river
valley are holding on to the cooler air a little longer with the
valley hovering in the 31-33 degree range at this hour. Saw a report
of about 3 inches of snowfall in parkdale, but with accumulations
struggling to exceed an inch. Looks like the cooler air will hold on
a few more hours before the southwesterly winds fully mix out those
locations with periods of precip continuing to spill over the crest.

As such, decided to extend the upper hood river valley snow advisory
through 8 pm, but would not be surprised if the advisory can be
canceled early as the southwest flow aloft does a better job of
scouring out the cooler pocket. Elsewhere, the aforementioned warmer
air aloft will see most lower elevations and oregon cascade passes
transition to rain this evening. This happens to coincide with the
likely period of heaviest precip rates keeping the main snow impact
to the highest elevations.

This system continues to bring abundant moisture associated with it,
with 2 to 4 inches of QPF possible for the coast range and cascades
and around 1 inch for the inland valleys. River forecasts continue
to suggest this will be enough to produce some decent rises on area
rivers, but not enough to cause flooding.

Exposed coastal winds have generally reached 45 to 50 mph so far
with CAPE disappointment having the highest gust at 57 mph. Expect
the winds to enhance just a little bit this evening bringing peak
gusts to around 60 mph on the beaches and headlands. Winds should
dramatically ease later this evening and overnight.

The associated cold front from the parent upper low will somewhat
stall out early Wednesday morning and then finally slide south
across the CWA Wednesday afternoon. This brings snow levels back
down to around 3000 feet for the evening. A secondary cold front
will then arrive Wednesday night to lower accumulating snow levels
to between 1500 and 2000 feet by Thursday morning. By then, the
heavier precip rates will have tapered off into a more showery
nature. However, the overall colder air mass will also bring
moderate instability and the possibility of small hail and
thunderstorms to the willamette valley and points westward including
the waters. Little change for Friday as well with showers and
potential coastal thunderstorms continuing. Jbonk

Long term Friday night through Tuesday. The active weather
pattern will continue into the weekend. Models are in fairly good
agreement tracking a low pressure system across the northeastern
pacific and across the forecast area. The trailing cold front
interacts with a fairly robust tap of moisture across the pacific,
transported in southwesterly flow as the main 500 mb pattern becomes
more zonal across the far eastern pacific and western conus. Snow
levels will increase as the air mass warms over the weekend through
early next week. However, confidence in the details of the forecast
remains a bit lower than normal, as the placement of the moisture
plume over the building ridge could either bring a period of heavy
rain to the region, or push north of the forecast area and keep our
region dry with the rain in northwestern washington. However,
confidence is a little higher for the start of next week as there is
general agreement that the next upper trough will swing across the
pacific northwester and bring another round of enhanced rain chances
along with lowering snow levels for the start of next week. Cullen

Aviation Tough TAF forecast with ceilings bouncing between
MVFR andVFR across the area. Looks like occasional visibilities
below 6 miles during heavier rain, but tough to time these
visibility differences in the taf. Expect a mixture of MVFR and
vfr conditions across the area through the evening and into the
overnight hours, but keeping up with these changing conditions in
the TAF will be difficult.

Pdx and approaches...VFR CIGS for now, but periodic lower
ceilings and visibilities are likely. Do not expect visibilities
to get any worse than 4 miles and do not expect any ceilings
below 1500 feet in the period. Southerly winds are starting to
increase and will continue to increase through the evening as the
front approaches. Bentley

Marine Forecast for the low pressure center today has matched
expected conditions with wind gusts peaking in the upper 40 knot
range. Seas have been a few feet lower than expected, likely due
to a slightly lower background swell since winds matched the
forecast quite well. Winds are dropping quickly behind the front,
but the front is slow to move across the waters as wave
development along the front retards its forward momentum. This
may lead to a second peak in the winds in the upper 40 knot range
sometime this evening.

Models continue to back off of the stronger solution for the
Thursday system with wind gusts only peaking in the high end
small craft range. Will continue to monitor this front, but it
appears concern is less than it was earlier this week. In
addition, seas now appear to be focused mainly south and west of
our area with the highest (upper teens) wave heights.

Still watching the next front to arrive on Saturday, but there is
still considerable uncertainty with regard to the strength of
this system. Bentley
