.DISCUSSION...
.Short Term...Tonight through Tuesday Night...Onshore flow has
resulted in an extensive area of clouds along the coast, along
with some drizzle or even very light rain. This will continue
through tonight and into tomorrow morning. Meanwhile, fog and low
clouds in the Illinois, Rogue, Shasta, and Klamath Valleys has
once again been slow to erode, and it is unlikely that they will
clear today, as the inversion remains strong, high level clouds
have shielded the region from solar heat, and mid level winds
have been unable to scour into the valleys.
For these areas that have remained sun-free for several days now,
a change in the pattern is on the way, arriving tomorrow as a
cold front with winds and rain, and the potential for clearing on
the back side of the front Tuesday. This system, currently well
to our north, is fed by a Pineapple Express, a dense plume of
moisture feeding into the coast of Washington State direct from
Hawaii. As the boundary moves south, a weak ridge over the eastern
Pacific will begin to intrude on the plume, cutting the front off
from its moisture source just as it pushes through southern Oregon
and northern California. The models have trended a bit slower with
this interference in the latest runs, with the result being a
slightly stronger system as it passes through.
It will be a quickly moving front, with rain beginning at the
coast late Monday morning, and showers exiting to the east around
midnight. This will keep precipitation amounts down a bit, but
given the stronger vapor transport and the more westerly component
to the winds (preventing the strongest downsloping), it will still
be a wet one, relative to our typical systems. Snow levels ahead
of the front will remain well above 6000 feet, but will drop to as
low as 4000 feet as the front passes and precipitation
transitions to showers. This means some light snow is possible
over the higher Cascade passes MOnday night into early Tuesday
morning, but the bulk of snow will fall on the higher peaks.
Winds will be a concern with this system, but mainly for areas
east of the Cascades, particularly in Lake County. With the
westerly component to the overall flow, our typically windy
valley locations will not see the channeling that usually
accompanies these fronts, so the main focus of winds will be the
higher terrain of the East Side, and of course the typical trouble
spots around Winter Rim and Summer Lake. 700 mb winds over that
area are forecast to peak around 65 kt, and this could easily
translate as gusts to the higher terrain, and in the mountain
waves downwind of Winter Rim. A Wind Advisory has been issued for
these areas of concern, and details can be found at PDXNPWMFR.
As mentioned before, the front will exit to the east and
precipitation should come to an end by late Tuesday morning. At
this point, we will see the development of a thermal trough to
our south and along the coast, and building high pressure inland,
naturally resulting in an easterly, or offshore, flow. This
should act to dry the area quickly, and fog and low clouds are
much less likely to develop in local valleys. Some more sheltered
locations, where the east winds won't reach, could still fog in,
but for the most part, we expect mostly clear, although cooler,
conditions Tuesday into Tuesday night. -BPN
.LONG TERM...Wednesday, Nov 17th - Sunday, Nov 21st...
The beginning of this long term period is likely to begin with a
moderate easterly flow in the lower levels of the troposphere across
the forecast area as high pressure builds from the Pacific Northwest
into the Northern Rockies. This enhanced easterly flow will push
drier continental air in from east to west. This is likely to clear
most or all of the forecast area of low clouds and fog. This
clearing is likely to actually occur largely during the day on
Tuesday and then continue into Wednesday morning as easterly winds
maximize. This should result in a mostly sunny Wednesday, though
high clouds from the next frontal system are currently expected to
overspread the area in the afternoon and evening.
Thursday into Friday low pressure and it's associated frontal system
are expected to push onto the West Coast with the center of the low
most likely moving inland between Lincoln City and Astoria. This
will bring another round of moderate precipitation to the forecast
area, especially from the Cascades westward. Snow levels on Thursday
are likely to begin high, in the 6-8kft range and then lower into
the 4-6kft range Thursday night into Friday. This frontal system
will have some moderate to locally strong winds with it with gales
likely across a portion of the coastal waters and along the coast.
Some wind advisories are possible in areas that are prone to getting
enhanced winds out of the southwest, primarily the Shasta Valley and
east side.
Current indications from the GEFS and ECE are that next weekend will
bring a period of high pressure yielding mostly dry weather. Of
course, with the ground being wet ahead of this and the sun angle
low, low clouds and fog could again become trapped in the bigger
west side valleys. Early indications from the ECMWF control run and,
to a lesser degree, the deterministic GFS, indicate there may be
enough cold air behind the Thu/Fri frontal system and related
easterly flow to mix out the valleys next Saturday. Of course, at
this lead time, it's difficult to trust that such a fine detail such
as that will be properly resolved, but it's worth mentioning for the
sake of tracking how that detail evolves with time. ~BTL

.AVIATION...14/18Z TAFs...A clear distinction between valleys west
of the Cascades and higher terrain is evident on satellite imagery.
All valleys with the exception of the Umpqua Basin are socked in
with a low overcast. Cigs in these valleys are mainly in the IFR
category. Overcast conditions are lifting along the coast and are
fluctuating between MVFR and VFR...so right around that 3000 ft
mark. Elsewhere...VFR conditions prevail with only a few altocumulus
clouds and a veil of thin cirrus to contend with. Valleys that
are experiencing the IFR ceilings may see some breaks but
generally are not expected to clear completely today. After
sunset...any cloud breaks in the valleys will quickly fill back
in. Also...mid level cloudiness will increase as the next weather
system approaches the coast but VFR ceilings will remain outside
the western valleys. - Sargeant

.MARINE...Updated 230 PM PST Sunday 14 November 2021...A building
west swell late tonight will mark the advance of a strong front that
will begin moving towards shore Monday morning. South Winds ahead of
this front will pick up tonight and peak during late Monday morning.
A large majority of models suggest wind gusts will excede gale force
within roughly 15 NM of shore north of Cape Blanco as the winds get
pinched along the coast. However, this front should advance on shore
fairly quickly and so the duration of gale force winds are not
expected to last more than 6 hours or so. Winds will shift quickly
to the northwest and decrease after the frontal passage.
Behind the front Monday evening, winds will be quick to reverse from
south to north and the west swell should reach its peak (10-11 ft at
10 seconds). These north winds will develop quickly late Monday
night and are likely persist into Wednesday morning because strong
high pressure offshore and a thermal trough over northern California
will maintain a summer like north wind pattern south of Cape Blanco.
Close to gale force winds will be possible, peaking Tuesday
afternoon, but this time south of Brookings in the outer waters.
Confidence is growing that the pattern will remain active during the
second half of the week. A strong front is possible on Thursday that
may result in rapidly building seas and winds approaching gale
force. -Miles/Sargeant
