Synopsis for the southern washington and northern oregon coast.. An occluded front is lifting north through the waters today. Winds are becoming southerly behind the front. Winds decrease between systems Tuesday before another front lifts north into the waters on Wednesday. A weak surface low will approach central/southern oregon coast Thursday into Friday. Another weak front may arrive over the weekend.

Synopsis Generally cool and showery weather will persist over
northwest oregon and southwest washington this week except for
Tuesday and Saturday, which will stand the best chance of ending up
dry.

Short term Today through Thursday... Visible satellite imagery
this afternoon shows a surface low pressure off the pacific northwest
coast. An occluded front is currently in the process of moving across
western oregon. This is resulting in widespread light rain falling
across northwest oregon and southwest washington. As colder air aloft
filters over the region this afternoon, expect the lower to middle
part of the atmosphere to destabilize and precipitation to turn more
showery in nature. There remains a chance this destabilization aloft
will couple at least briefly with daytime heating to allow a strong
shower or two to pop between 4-7 pm, particularly across the central
and southern willamette valley. Shear profiles suggest there could be
a low end wind threat if something develops. Model soundings appear a
bit better for thunder chances over the waters, but the continued
lack of sustained convection upstream suggests this remains a low
threat as well.

Given there should be at least some clearing overnight and with
weakening surface winds, some patchy fog should develop late tonight
into Tuesday morning in the valleys of the coast range and in the
willamette and lower columbia river valleys. Weak shortwave ridging
will push across the region on Tuesday, which should lead to a
mainly dry day across the area with temperatures topping out around
60f.

However, the aforementioned surface low pressure currently found off
the oregon coast will dumbbell around itself and eventually move
close enough to bring another round of rain spreading
north-northeastward across the region on Wednesday. Depending on the
track of the surface low pressure, we could see additional showers
linger into Wednesday night, but generally we should see a reduction
of rain chances with the loss of daytime heating. With the cool upper
level trough still overhead on Thursday, we should see shower
activity increase in coverage and intensity during the afternoon and
early evening hours once again. Neuman

Long term Thursday night through Monday... Models are in good
agreement the shortwave trough bringing showers to the area on
Wednesday and Thursday will be slowly exiting the region on Friday.

This should bring a bit more sunshine to the area, but there may yet
be another round of afternoon and early evening showers on Friday,
particularly for areas away from the coast and across the higher
terrain. Models and their ensembles are in fair agreement shortwave
ridging will move over the pacific northwest sometime Saturday. This
should lead to a mainly dry day with lowland locations likely rising
well into the 60s Saturday afternoon. Models then suggest the
shortwave ridge will shift east of the region Saturday night into
Sunday and open the door to increasingly moist southwesterly flow.

This will likely result in another frontal storm system bringing
another round of cool and showery weather to the area Sunday and or
Monday, but timing uncertainty remains. As a result, pops were
increased to near or above climatology per a blend of model and
ensemble guidance. Neuman

Aviation A occluded front is lifting up from the southwest
this afternoon, bringing steady light rain across the region.

Conditions are generally stillVFR for most locations, with cigs
around 4-6 kft. However, konp and kcvo have seen MVFR cigs
develop over the past couple of hours. So it does appear that
there will be a couple of hours of MVFR conditions right along
and just behind the front. The front will clear the southern
portions of the CWA by late afternoon, then lift through the
north by early evening. Expect conditions will improve to
predominantlyVFR this evening behind the front. There will be
some post-frontal showers tonight, but expect them to decrease
steadily during the overnight hours and be mostly done by tue
morning. It appears that clouds will scatter out some overnight,
particularly over the southern half of the cwa. This should
allow for some fog and low stratus development over the lowlands
late tonight into Tue morning.

Kpdx and approaches...VFR conditions should persist through most
of the afternoon. Expect a few hours of high MVFR lowVFR right
along and just behind the frontal passage during the late
afternoon and early evening hours. Then conditions should improve
toVFR. CIGS may try to lower to ifr or low MVFR late tonight
into Tue morning. Pyle

Marine A low pressure system over the NE pacific is pushing an
occluded front through the coastal waters today. Winds are
shifting to southerly behind the frontal passage from south to
north. Expect gusts of 20 to 25 kt at times through late
tonight. Winds will gradually subside early tue, and generally
remain 20 kt or less through Tue night. A second surface low will
approach the coast on wed, resulting in another occluded frontal
passage. This one looks to be a bit stronger than today's front,
so expect another round of solid small craft advisory winds,
with an outside shot at some low-end gales. Winds subside just a
little on thu, but probably remain gusty as the weakening surface
low slowly pushes onto the central or southern oregon coast.

Another front may arrive over the weekend.

Seas will be hovering around 10 ft through tonight. In addition,
they will be quite choppy as longer-period westerly swell
interacts with short-period wind waves and fresh swell being
generated by the gusty southerly winds. Seas should drop back
below 10 ft by early tue. The Wed Thu system should push seas
back into the low teens for a period, before they drop back below
10 ft late in the week. Pyle
