Synopsis Wet and unsettled weather will continue this week. A warm
front was lifting north through northwest oregon and southwest
washington this morning, ushering in more rain. Expect some windy
conditions near the coast this afternoon. A trailing cold front will
linger over the forecast area tonight and Wednesday for more rain,
especially near the coast and in the north interior areas. Snow
levels in the cascades will remain relatively high. The next cold
front sweeps through on thanksgiving with snow levels in the cascades
lowering close to the passes Thursday night and Friday. Look for some
lingering showers Friday before the next system arrives on the
weekend. Look for snow levels lowering back near the cascade passes
again Sunday night and Monday.

Short term Today through Thursday... National weather service
doppler radar shows precipitation over much of southwest washington
and northwest oregon associated with a warm front the was moving
north through the forecast area. The freezing level was 10300 feet at
salem this morning, so it is pretty much rain everywhere except on
the higher peaks. The warm front is forecast to move north later
today and tonight, but a trailing cold front will then be draped over
the area tonight and Wednesday, with the greatest likelihood of rain
along the coast and in the north interior areas as we get further
into Wednesday.

The models still show a good amount of wind south of the warm front
over the coastal waters as we go through the day, with the peak this
afternoon. We should see some good winds along the coastal headlands
and beaches, but it is not clear whether we can reach warning
criteria. Will stay with the current forecast of just under warning
criteria for now for the beaches and headlands. We will also see some
east wind through the gorge due to the easterly gradient induced by
the associated surface low out between 130w and 140w. The east winds
will be strongest today, but linger for a couple of days.

The next cold front approaches the coast Wednesday night and moves
through the forecast area midday on thanksgiving. Snow levels will
remain high initially with this system. The front will move east of
the cascades later in the day on thanksgiving, with lower snow levels
in its wake, possibly lowering to near cascade pass elevations
Thursday night and Friday. Tolleson

Long term No changes. Previous discussion follows...

Thursday night through Monday... We will be transitioning to showers
by Thursday night, which will be diminishing Friday. The models keep
speeding up the next system, which may arrive by Saturday, and then
may linger into Sunday. The next system is expected Monday. After a
brief drop in snow levels Friday mainly in the north part of the
forecast area, snow levels rise gain significantly Saturday before
dropping a bit again Sunday. May get a brief rise in snow levels
again Sunday night into early Monday at the leading edge of the next
system. Overall, the unsettled weather pattern continues.

Aviation As the warm front lifts north across the region today, we
are generally seeing improving conditions at our terminals, though
still some pockets of MVFR conditions. Conditions should remain
predominantlyVFR through early this evening, until we start to
stabilize around 06-09z tonight. As we stabilize, will likely see
cigs sink to MVFR with pockets of MVFR visibility as well.

Predominantly MVFR conditions to persist into Wednesday morning.

Kpdx and approaches... PredominantlyVFR conditions through the day
today. CIGS will sink down this evening to MVFR around 08z.

Generally, east to southeast winds continue through tonight. -mccoy

Marine Warm front lifting north across the coastal waters today.

Already starting to see gale force winds creep into the buoys.

Generally strongest winds today will be over the outer waters, or 10
miles and farther offshore, but will see gusts 30 to 35 kt on the
inner waters at times as well. Wind will ease this evening, with
generally 25 to 30 kt gusts on the waters later tonight into wed.

Another front will approach the region later Wed into thu, with
another round of southerly gales at that time.

Seas building today, mostly due to gusty winds. So, will see choppy
seas today into this evening, with seas 8 to 10 ft early this am
building to 14 to 18 ft by early afternoon. Again, higher seas will
be farther offshore with the stronger winds. Though seas subside just
a tad later tonight, still stay in the 13 to 17 ft range through wed
night. -mccoy rockey

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
