Synopsis for southern washington and northern oregon coast.. A strong front will bring gale force winds as it drops southeastward across the waters today and tonight. A coastal jet could enhance winds even further within 20 nm of the coast. This front will stall near the south oregon coast early Monday before lifting back northward and spreading southerly winds back into the waters late Monday and Tuesday.

Synopsis The upcoming week looks unsettled and wet. A weak upper
ridge over the pacific northwest early today will yield to a cold
front that will slowly move SE through the region late today through
Monday. The front weakens later Monday then lifts north as a warm
front for more rain Monday night into Tuesday. The warm front will
linger across washington through wed. The next cold front moves
through on thanksgiving. A little drying early next weekend will be
followed by more precipitation the second half of next weekend.

Short term Today through Tuesday... Satellite, weather cameras
and surface observations indicated widespread fog this morning in
the valley. Metars indicated only a couple of locations with 1 4
mile or less visibility early this morning, likely due to ceilings
generally ranging from 200 to 400 ft. Will hang on to the dense fog
advisory in the south willamette valley, but at this point will
refrain from any expansion of the advisory it given the lack of
widespread low visibilities.

A cold front seen in satellite imagery extending SW from vancouver
island early this morning is expected to move SE today and tonight,
moving into SW oregon early mon. An area of modest moist low level
isentropic lift, seen along the 290k isentrope, precedes the front,
and will slowly spread a chance for rain into the NW half of the
forecast area today. Given the current position of front, 00z nam
looked too agressive in spreading the precipitation SE today, so
have leaned towards the other slightly slower solutions. As with
previous model runs, low level pressure gradients along the coast
tighten up with the approach of the cold front late today. Will be
upgrading the current high wind watches to warnings for this
afternoon into tonight, and adding warnings for the higher
elevations of the willapa hills and north oregon coast range. Models
continue to indicate 850 mb SW winds peaking in the range of 55 to
65 kt tonight, which coupled with precipitable water values of 1.1
inches spreading onto the coast with the front suggest some rather
heavy rainfall rates associated with the frontal passage. The front
is expected to remain progressive as it moves through the area
tonight into early mon, so at this point there is no reason to
expect any type of river flood threat. Snow levels over the south
washington cascades still expected to be slow tonight, which coupled
with the heavy precipitation rates suggests some heavy snow for the
higher south wa cascades tonight. Snow levels though expected to
climb above 6k ft by Mon morning. Will convert the current winter
storm watch into a warning for the south wa cascades tonight above
4500 ft.

Models in good agreement showing the front stalling to the south of
the forecast area mon, but with much of the region remaining in a
baroclinic zone, suggesting a continued threat for rain. As a short
wave passes, the upper ridge rebounds Mon night and tue, lifting the
old frontal boundary back to the north as a warm front. This spreads
the main area of rain back to the north, and put the region into a
warmer than normal air mass with snow levels above 8000 feet.

Long term Tuesday night through Saturday. No changes. Previous
discussion follows. Models in some disagreement for this time
period. The warm front from Tuesday lingers some and lifts a little
north Wednesday for some precipitation around, followed by the main
front moving through on thanksgiving for a decent shot of rain.

After some lingering shower Friday with snow levels trying to stay
above the passes, there could be a little drying early next weekend
before the next system approaches. Bishop tolleson

Aviation Much of the interior lowlands remain under lifr
conditions in stratus and fog, whileVFR continues at the coast.

There have been some improvement in vis over the last few hours.

It will be a challenge forecasting the timing of flight category
changes due to the mix of mid high clouds entering the area,
timing of increase in winds to help mix the clouds and fog, and
other factors associated with the approaching system. Overall
expect early morning to remain lifr, then with some mixing later
in the morning lifting to ifr. The afternoon hours should see
clouds breaking up forVFR conditions.

A strong front will spread rain and MVFR or ifr conditions onto
the coast late in the afternoon and evening. There will also be
strong southerly winds developing at the coast, with gusts of 35
to 45 kt possible. The front will begin to spread into the
interior lowlands late in the evening, but expectVFR to prevail
through the evening then most likely see MVFR CIGS and vis
overnight as the front moves through.

Kpdx and approaches... Expect lifr CIGS to persist through the
morning with conditions improving toVFR during afternoon. MVFR
conditions may to develop during the evening, but most likely
overnight.

Marine Winds at buoy 46089 just west of the northern marine
zones have slowly increased overnight as the strong front
approaches. The front will move southeast through the waters so
expect gales to start in the northwest and spread southeast.

Will likely see gale force wind gusts of 40 to 45 kt across the
waters Sunday and Sunday night. Coastal jet development will
likely enhance winds within 20 nm of the coast, and we could see
some storm force gusts of 50 kt within this region. Confidence is
low enough at this point that will continue to mention the
possibility in the forecast, but continue with a strongly worded
gale warning. One significant change over previous forecast is to
extend the gale warning for the central oregon coastal waters
through late tonight. Seas will build into the upper teens and
may briefly reach 20 ft along the front this evening. Seas will
be dominated by wind waves or fresh swell with periods of 8 to 10
second range. Seas will subside Monday to near 10 ft or slightly
below.

The aforementioned front is forecast to stall out near the
south oregon coast Monday morning before lifting back northward
on Monday. When it does so, expect high end small craft advisory
to low end gale force southerly wind gusts of 30 to 35 kt to
spread northward across the waters. This should also result in
seas climbing well into the teens once again early next week
where they look to linger through at least thanksgiving.
