Synopsis Showers will decrease this evening as high pressure
briefly moves over the area for a dry period tonight through Thursday
morning. An approaching cold front will bring more rain by Thursday
evening, with showers persisting through Saturday morning. Some sun
is possible Saturday afternoon. Another front is expected on Sunday.

Short term Tonight through Saturday... Showers have waned across
the area this evening as expected. The only areas of showers remain
in the north oregon and south washington coast and coast range and
the north oregon and south washington cascades. Have kept a 20 to 30
pop in these locations through the overnight and into the morning
hours tomorrow, but expect most locations to stay dry.

Removed the fog mention for the overnight hours as clearing in the
valley is struggling to materialize. Even if the clearing does
develop, winds appear to remain strong enough to keep low levels
mixed. /bentley
previous discussion follows...

models remain rather persistent with stalling the front along the
coast Thursday morning. This will leave most locations away from the
coast with dry weather for most of Thursday under increasing clouds.

However, at the coast, expect rain by late Thursday morning. Rain
returns to the interior by Thursday evening as the front moves
onshore. Rain with this front could be heavy at times. Rainfall
amounts through Friday are around 1 to 1.5 inches along the coast and
in the coast range. The interior could see up to 0.75 inches. Snow
levels will generally remain above pass level, but the cascades could
see another 3 to 5 inches.

Rain looks to turn to showers by Friday afternoon as the front moves
further inland. Despite this, the upper level trough will help to
maintain showers into Saturday. Showers decrease Saturday afternoon
as high pressure briefly rebuilds into the region. This could bring a
few hours of nice weather with occasional Sun breaks on Saturday. /64

Long term Saturday night through Wednesday... Lingering
showers Saturday night will come to an end by early Sunday as
shortwave ridging moves across the region in between systems.

However, the next round of moisture in the form of a pacific front
is not far behind and will likely spread another of round of steady
rain later Sunday. Confidence in the forecast for the first part of
next week is a bit lower, however, as forecast models do present a
rather large spread of solutions. While the generally progressive
pattern may continue, the GFS (and at least a handful of gefs
members) would favor a somewhat drier solution until around early
Wednesday. Continued to utilize a blend of models, resulting in at
least some mention of precipitation through the period, though. Snow
levels remain near or above the cascade passes through the long term
period. Meanwhile, temperatures will remain generally a few degrees
below seasonal normals for the first half of next week. Cullen

Aviation Vfr CIGS cover much of the area this evening with
the main remaining shower activity along the S wa and N or coasts
and in the S wa and N or cascades. These conditions will tend to
prevail overnight and Thu morning, though CIGS could locally
lower to MVFR. Rain and lowering MVFR CIGS with the next front
will spread onto the coast Thu afternoon, and get close to the
inland TAF sites by late Thu afternoon and especially thu
evening.

Kpdx and approaches... MainlyVFR CIGS tonight through Thu morning
with a chance of MVFR CIGS 09z-18z.VFR conditions Thu afternoon
but rain is possible after about 22z. Pt

Marine Winds have dropped below small craft advisory criteria
and that advisory ended a couple of hours ago. Winds will stay
below small craft advisory criteria overnight but ramp up
Thursday, reaching gales in the outer waters late Thu morning or
early Thu afternoon, and in the inner waters in the late thu
afternoon or evening. Gusts could reach 40 to 45 kt with this
incoming front. The winds will ease to small craft advisory
values after the front moves onshore around midnight Thu night.

Winds should drop below small craft advisory values Friday
night and remain so until the next front brings high end small
craft advisory values or low end gales Sunday.

Seas are running around 2 ft above model guidance this evening
and have extended the small craft advisory for hazardous seas
until 11 pm this evening. Seas should climb above 10 ft with the
next front Thu afternoon, peaking around 15-17 ft Thu night,
falling to around 10 ft Friday. Wave models indicate seas will
tend to hover around 10 ft this weekend, reaching their lowest
values Saturday night, then ramp back up into the lower to mid
teens Sunday night. Pt
