Synopsis for southern washington and northern oregon coast.. A surface low will move from vancouver island area into western wa this morning. Another system will take a similar track later tonight and Sun. The series of systems through the weekend will result in seas building into at least the mid teens. A quieter period sets up Mon and Tue, then active weather returns.

Synopsis Got snow? We will. Head for the cascades this weekend.

Cool air mass remains over the region into next week. Upper low will
push across the pac NW today, with plenty of showers, and snow in the
mountains. Brief let up in precipitation this evening. But, much
stronger system arrives on Sunday, with rain for the lowlands, and
very heavy snow and winds in the cascades.

Short term Today through Monday... Upper low pushing now digging
into the pac nw, with plenty of showers over western washington and
northwest oregon this am. So far, not so much in way of showers over
the interior lowlands, as the westerly flow has been leading to
enhancing the rainshadowing effect off the coast range. Still think
will have some showers over the interior lowlands, but will be much
weaker than those over the higher terrain.

Temperatures not as cold as earlier thought, with many lowlands in
the middle to upper 30s, and 40s along the coast. This due to
prolonged southerly winds. As such, snow levels are sitting around
1500 feet this am. Even the astoria esrl profiler shows snow level
now up at 1800 feet over astoria. Snow levels will sit rise a tad
more today. Will end the snow advisory for the willapa hills and the
coast range, as appears threat of snow is only on the higher peaks.

Silver lining of this strong westerly flow is the highly favorable
upslope orographic flow for the cascades. Models show 35 to 45 kt of
850 mb flow, and combined with the cool air mass, will have enhanced
precipitation rates over the west slopes of the cascades, and to some
degree also for the coastal mountains. Think will get 6 to 12 inches
of snow in the cascades today, with 2 to 7 inches for the coastal
mountains and cascades foothills, generally above 1000 to 1500 ft.

Will maintain current winter weather advisories for the higher
terrain of the willapa hills coast range, as well as the foothills of
the cascades and the higher cascades for today.

Models all indicate decreasing showers later this afternoon into the
evening. So will keep that trend.

A rather wet and vigorous system arrives later tonight into Sunday,
with precipitation spreading into washington later tonight. Snow
levels still at 2000 feet, or slightly higher. This will keep lower
elevations as rain. Precipitation could be heavy at times in the
morning. While precipitable water values of 0.50 to 075 inch are not
all that high, they are higher than have seen in awhile. So, would
expect decent shot of QPF on Sunday. Models vary a bit, but overall
0.50 to 1.00 inch for the coast mtns, and 0.20 to 0.50 inch lowlands.

But with low snow levels, the 0.75 to 1.25 inch over the cascades
will fall all as snow, about 1 to 2 feet of it. Pressure gradients
stay strong over the cascades on Sunday, supporting ridge top
westerly winds of 15 to 30 mph and gusts 35 to 50 mph. With the
powdery snow, these winds will create significant blowing and
drifting of snow. Currently have winter storm watch for the cascades
for late tonight and Sunday, and will let day shift upgrade to
warning. But, very well could see blizzard warning in the cascades
rather then winter storm, due to very windy and snowy conditions.

Again, will let day shift decide this. Not quite as much wind lower
down in the higher terrain of the foothills, but still lots of snow
to fall. Likely to get 9 to 16 inches for late tonight and Sun above
2000 feet.

The cold system will pass the region Sunday night, with decreasing
showers. Snow levels drop again, such that could see minor
accumulations as low as 500 to 1000 feet again. Showers will continue
to decrease through the day mon, and clouds may try to clear from
north to south in the afternoon. But it will be
another chilly day. rockey.

Long term Monday night through Friday... Fairly active pattern
will continue through the long range. Operational 12z GFS and ecmwf,
when compared to the ensembles, are in fairly good agreement
regarding the overall large-scale details. Another short-wave drops
into the area from the northwest Mon night and tue. This system will
have a more maritime influence. Snow levels Mon night will generally
be 1000 to 1500 feet, although down to 500 feet in the gorge and
east skamania county. Model 1000-500 mb forecast thickness values
will be in the 525-530 dm range with 850 mb temps around -5c. This
system slides through the forecast area tue. QPF amounts do not look
all that impressive, but could be enough for snow advisory amounts
in the S washington and N oregon cascades.

Gfs 500 mb spaghetti plots start to show more variation beginning
wed. A deepening upper level trough along the british columbia coast
will allow a more moderate west to northwest 500 mb flow to impact
the area. A leading short-wave is expected to reach the area wed
night. The ECMWF indicates a complex surface low pressure off
vancouver island 12z Thu with an 8-10 mb kast-koth south gradient.

The operational 12z GFS is much different, with a closed low off the
central oregon coast and offshore low-level flow through the gorge.

The ncep GFS ensembles valid 00z Thu are all over the place,
suggesting low confidence in the general forecast. Would tend to
favor the ECMWF at this time and have trended the forecast in that
direction. Eventually, the large upper level trough takes up
residence over the NE pac 00z fri. This would maintain an
unseasonably cool air mass over the region, with snow levels
generally 1000-1500 ft. There is better agreement between the gfs
and ECMWF Thu night and fri, leading to better forecast confidence.

All in all, the extended period will continue the cascade snowpack
improvement, but not expecting any additional valley floor snowfall
during the period. Weishaar

Aviation Cool upper trough sliding southeast across the area
today. Showers increasing currently as embedded shortwave moves
ashore. Expect mainly MVFR CIGS of 1500-2500 ft, with short
periods of reduced vis with heavier showers. Expect -shra at taf
sites, but may see -shrasn briefly mixed in this morning.

Showers decrease by midday with generally improving conditions
for the afternoon and evening. Southerly winds gusts 20-25 kt
will ease later in the morning the switch to southwest-west
through the afternoon. A warm front moves ashore late tonight and
early Sun with conditions lowering to MVFR or lower at the
coast.

Pdx and approaches... A mix ofVFR and MVFR with lower cigs
1500-2500 ft through 18z. Generally improving conditions after
18z with -shra. Southerly winds gusting 20-25 kt will switch to
out of the west to northwest after about 16z. Mh

Marine 1012 mb low pres over vancouver island, b.C. Will track
southeast into western wa this morning and weaken. This feature
will increase winds over the waters. Low end gales are expected
over pzz270 this morning. Small craft advisories for the
remainder of the waters today. There will be a bit of a lull in
the winds later today into late evening before another system
drops south and brings more small craft advisory threshold winds
through Sunday. Also gales are again pretty likely over the
northern waters later Saturday night and Sunday morning so have
put up a gale watch.

Seas are forecast to climb into the mid teens today. The wave fetch
is parallel to the b.C. And southeast ak coast with the core of
the larger seas currently just offshore of vancouver island,
b.C. Bouy 46207 near the north end of vancouver island is reading
20 ft at 11 seconds. The coastal waters should see seas peak
around 17-18 ft this later this morning. Seas slowly subside
later tonight but should pickup to the mid and upper teens late
sun into Mon as more systems maintain the fetch pointed toward wa
& or. Mh
