Synopsis Dry weather will continue through Tuesday, along with
unseasonably warm temperatures and a breezy offshore flow. A low
passing by to the south brings a small chance for rain mainly to the
southern part of the forecast area Wednesday. Chances for rain
increase through the end of the week as a more progressive weather
pattern returns.

Short term Tonight through Thursday... Models show the upper
ridge over the pacific northwest Monday to shift slowly east through
the middle of the week. A moderately strong pressure gradient east
to west across the forecast area Monday afternoon is expected to
shift more towards the gorge by Tuesday afternoon. This will allow
the east winds to subside some tonight and Tuesday across much of
the forecast area, except in and near the gorge where windy
conditions will continue. The ridge and offshore flow will keep
skies clear through tonight, before some high clouds start moving up
in an increasing southerly flow aloft on the backside of the upper
ridge Tuesday. Temperatures will also remain well above normal
through Tuesday.

Tuesday night and Wednesday models have been consistent on showing
an incoming upper trough splitting as nears the coast, with a cutoff
low heading into central california. Time height cross sections
indicate moisture remains mostly in the upper levels above 10k ft
Tuesday night and Wednesday. Coupled with weak lift, this will limit
chances for any rain to low pops across the southern part of the
forecast area Wednesday. Temperatures will remain mild without a
chance in the air mass, although clouds will tend to hold high
temperatures down some Wednesday, particularly in the south.

Wednesday night and Thursday a weak upper trough trailing the upper
low reaches the forecast area. This will bring an increase in low
level moisture as the offshore flow from earlier in the week finally
comes to an end. While the dynamics and moisture profiles are
something less than impressive, will include a slight chance for
showers to much of the forecast area as the trough moves through.

Long term Thursday night through Monday... Once the Thursday
evening shortwave trough moves through, there is a brief break in
the action before another trough and pacific cold front approach in
the afternoon Friday. There is some suggestion in the models for
this shortwave to also split as it approaches the coast and moves
away from the parent longwave trough out near 150w. Still, this one
looks a little more promising for precipitation chances as a cold
front accompanies the short wave Friday night and the upper ridge by
then has shifted east across the rockies. Decreasing showers follow
Saturday on the backside of the torugh, then Sunday looks
potentially dry as a shortwave ridge moves across. Timing in the
models at this point becomes more questionable, but it appears
another chance for rain comes as early as Monday as a progressive
pattern continues.

Aviation Vfr conditions will continue across northwest oregon
over the next 24 hours. East pressure gradients weaken slightly
overnight but increase again Tuesday afternoon. Expect gusty
east winds in and near the western columbia river gorge, across
the coast range and downwind of coast range passes along the
coast. Winds will diminish slightly overnight but increase again
Tuesday. Pressure gradients finally relax some Wednesday night.

Kpdx and approaches...VFR conditions continue through the next 24
hours. East wind increasing to 15 to 25 kt with gusts to 35 kt.

Decreasing a bit over night then increasing Tuesday. Higher
gusts to 40 kt in eastern approaches near the gorge. Schneider

Marine high pressure continues east of the cascades with a
trough along the coast. Gusty east winds continue in the northern
waters especially below the coastal gaps. Small craft advisory
for the waters north of cascade head will continue through
Tuesday morning. It is possible winds will continue Tuesday
afternoon but models show some weakening of the gradient over the
waters and the coast so winds should diminish a little Tuesday
afternoon. Wednesday a dissipating system approaches from the
southwest. As a result may see a flow reversal reaching the
central coast Tuesday Wednesday timeframe. This will likely bring
low stratus or fog with it. A stronger front is currently timed
affect the waters Friday with south winds in the 15 to 25 kt
range.

Seas have settled to 6 to 7 ft over the waters. Seas remain
below 10 feet through Friday. However a longer period swell is
forecast to arrive by Tuesday afternoon. With the strong and very
strong ebb current occurring this will push the columbia river
bar above small craft criteria. Thursday a long period swell near
20 seconds reaches the waters, but the period decreases quickly
as the swell builds above 5 ft. Current enp and ECMWF wave models
show the swell building 13 to 15 feet on Saturday. Schneider

Pqr watches warnings advisories
Or... None.

Wa... None.

Pz... Small craft advisory for winds until 11 am pdt Tuesday for
coastal waters from CAPE shoalwater wa to cascade head or
out 60 nm.

Small craft advisory for rough columbia river bar until 5 pm
pdt this afternoon.

Small craft advisory for rough columbia river bar from 3 pm to
9 pm pdt Tuesday.
