Synopsis An upper level trough will support showers across
southwest washington and northwest oregon today and tonight. Dry, but
cold weather is expected Thursday and Thursday night before a warm
front brings another round of rain and mountain snow Friday through
the weekend. The snow levels will start out relatively low Friday
morning, then rise to 1500 to 2000 feet in the afternoon. Showers are
likely to continue into early next week as the upper trough remains
over the pacific northwest.

Short term Today through Friday night... Radar imagery shows
persistent showers over SW washington and NW oregon early this
morning as an upper level shortwave trough is moving over the region.

Snow levels have lowered to around 1400 feet across SW washington and
extreme NW oregon to 2000 feet in lane county, oregon. Web cameras
and surface weather observations indicate that the winter weather
advisories for the cascades and the cascade foothills are on track
and have not made any additional changes to them.

High pressure filling in behind the shortwave will end showers from
north to south this afternoon through tonight. Gradual clearing
combined with a colder airmass will result in widespread below
freezing temperatures tonight. Weak winds and lingering surface
moisture will likely result in areas of freezing fog developing late
tonight into early Thursday, unless stratus forms first and limits
the radiation cooling.

Dry weather continues Thursday and Thursday night as a transitory
upper ridge moves over the pacific nw. The fog should clear by early
afternoon in most places, but light north winds through the
willamette valley may result in later clearing of low clouds and fog
in the south willamette valley.

Another low drops south from alaska early Friday, and models are
consistent in forecasting a warm front returning precipitation to sw
washington and NW oregon Friday and Friday night. The snow levels
will start out low, around 500 feet in the north interior valleys
with the onset of precipitation Friday morning, but warm air
advection should rapidly raise the snow levels to 1500-2000 feet by
the afternoon when the heavier precipitation is expected. Do not
expect any accumulating snow below 1000 feet Friday morning, but the
cascades and cascade foothills will likely see another 3 to 8 inches
of new snow Friday and Friday night. ~tj

Long term No changes. Previous discussion follows... No changes.

Previous discussion follows... Saturday
through Tuesday... Models begin the weekend in fairly good agreement,
with another cold upper trough with alaskan origins digging south
into the pacific northwest. A weak low coming down off the coast as
with previous systems, will enhance the chances for showers Friday
night through at least Saturday night. Thermal fields suggest
continued low snow levels, but not likely to impact valley floors
thanks in part to the low level onshore flow. The dynamics look
favorable through for accumulating snow down into the coast range and
cascade foothills. Showers likely to decrease Sunday and Sunday night
as onshore flow weakens.

Operational model solutions diverge sharply Sunday night through
Monday night, with ec most strongly indicating the weekend trough
weakening, and another east-west oriented upper trough redeveloping
further north along or north of the canadian border. A number of the
gefs perturbations, and eventually the GFS operational run shows
this trend, which will likely result in some warming of the air mass
early next week. For now prefer not to overly commit too much to the
ec or any other model for that matter given the uncertainties, but
will need to keep pops higher than operational GFS pops early next
week, more in line with a blend of nbm, ec and climatology.

Aviation Post frontal showers in northwesterly flow at surface
and aloft today. Showers end as flow turns northerly later in the
day and evening. Generally expect a mix ofVFR and MVFR cigs
through midday wed, thenVFR likely for the afternoon and
evening. Mountains obscured at times through about 00z thu, then
gradual improvement is expected. The interior TAF sites may
have ifr fog develop later tonight into thu.

Kpdx and approaches...VFR prevailing but will likely see
occasional MVFR CIGS through early afternoon. Showers taper off
late in the day and evening. May see fog develop late tonight.

Mh

Marine We remain in a northwesterly flow pattern through the
end of this week. A low pressure system will drop south along
coast today. High pressure over the NE pacific will keep pressure
gradients strong enough for gusts 30 to 35 kt today, then winds
gradually ease from north to south tonight. High pressure
strengthens east of the cascades by Thu for north to northeast
winds, but weaker than today. High pressure inland weakens late
thu as the next low pressure drops in from the bc coast fri.

Expect this one to be a bit weaker, but will likely bring
moderate small craft advisory winds.

Seas will also build with this system, getting back up over 10
feet then peaking around 14 to 17 feet on today. Seas gradually
subside through the day thu. Seas aren't expected to drop back
down below 10 feet, though, until late Thu night. Seas build back
up above 10 feet on sat. Mh
