Synopsis The upcoming week looks unsettled and wet. A cold front
will slowly move onto the north coastal areas this afternoon and
through the remainder of southwest washington and northwest oregon
tonight and Monday, stalling and weakening over the southern part of
the forecast area Monday afternoon. The front then lifts back north
across the forecast area as a warm front Monday night and Tuesday.

The front will linger over the area into Wednesday. Another cold
front will move through on thanksgiving with showers lingering into
Friday but decreasing later in the day. The next system is expected
Saturday night and Sunday.

Short term Today through Tuesday... As expected, there is a fair
amount of low stratus and fog in the inland valleys this morning, but
dense fog is sparse, mainly in the south willamette valley. The fog
should continue to decrease and lift the remainder of this morning
and early this afternoon as winds increase ahead of the next incoming
front.

The next front is still well offshore on radar and satellite imagery,
but is continues to be forecast to spread rain onto the north coast
and in the the adjacent coastal mountains this afternoon, and
probably not much farther inland until this evening. The front will
slowly sag south through southwest washington and northwest oregon
tonight and Monday, briefly weakening and lingering in the south part
of our forecast area Monday afternoon.

There will be decent winds along the coast and in the coastal
mountains this afternoon and tonight ahead of the front, with the
strongest winds along the coastal headlands and beaches and over the
higher terrain of the coast range. It will also be breezy in the
inland valleys this afternoon and tonight, with gusts 30 to 35 mph
possible.

There is some residual cold air in the south washington cascades, and
will continue the winter storm warning there for tonight. Snow levels
will be rising across the oregon cascades today and tonight, finally
reaching the south washington cascades Monday morning.

The leftover front across the southern part of our forecast area
Monday afternoon continues to be forecast to lift north across the
forecast area Monday night and Tuesday for more rain. We will likely
see some east wind develop through the gorge and in the portland and
vancouver metro areas Monday night and Tuesday as the main low with
the warm front will be developing offshore and a bit outside 130w.

Snow levels will remain rather high in the cascades as well.

Rainfall amounts through Tuesday could reach 3-5 inches at the coast
and in the cascades, and 0.50-1.5 inches in the valleys. The rainfall
is not expect to cause flooding other than some localized urban
flooding should leaves clog storm drains, though area rivers and
streams will likely see some sharp rises this week. Tolleson

Long term No changes. Previous discussion follows...

Tuesday night through Saturday. 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 Lifr and ifr conditions will likely persist for a few
more hours across the central and northern willamette valley before
increasing winds scour out the low clouds and fog. An incoming front
will bring rain and breezy conditions tonight with a mix of MVFR and
low endVFR conditions for most TAF sites between 06-18z Monday.

Coastal locations will be most susceptible to ifr conditions during
this time. In addition, some elevated instability pushing over our
southern zones could bring a rumble or two of thunder between 03-09z
to konp and keug.

Kpdx and approaches... Lifr and ifr conditions will likely persist for
a few more hours before increasing winds scour out the low clouds and
fog. An incoming front will bring rain and breezy conditions tonight
with a mix of MVFR and low endVFR conditions between 06-18z Monday.

Neuman

Marine A front will move southeastward across the waters later
today and tonight. Winds will increase ahead of this front into gale
force criteria with widespread gusts of 40 to 45 kt. There could be a
few gusts to 50 kt within 20 nm of the coast due to a coastal jet
enhancement of the winds, but think this threat should be isolated
and short enough in duration to keep the gale warning intact for now.

Either way, expect seas to peak near 20 ft early this evening across
the northern waters and later this evening across the central oregon
waters. Seas should subside into the low to mid teens fairly quickly
after midnight and drop below 10 ft on Monday as winds remain weak
across the waters. The aforementioned front will actually stall
across the southern oregon waters Monday before lifting back
northward and spreading gale force winds back across the waters
either Monday night or Tuesday. Seas should respond accordingly and
climb back well into the teens where seas look to remain through
thanksgiving. An additional storm system or two looks possible next
weekend as well. Neuman
