Synopsis for southern washington and northern oregon coast.. High pressure prevails across the pac nw waters this evening, while low pressure remains nearly stationary well off the ca coast. The low will eventually merge with a stronger system pushing south from alaska, resulting in a broader low pressure system near the pac nw coast later this week.

updated short term, aviation, and marine discussions

Synopsis Rather quiet weather with morning clouds and fog in the
valleys continues through Tue under weak high pres. Wed and wed
night low pres off the ca coast will spread moisture north over the
region as a cold front from the NW pushes through bringing rain, and
then a cool showery air mass for the end of the week.

Short term Tonight through Thursday... Dropped overnight low
temperatures a couple degrees, so now temperatures in the north and
central willamette valley will be flirting with freezing. No
additional changes. Previous discussion follows. -mccoy
the weak upper low off the oregon coast near 43n 129w is expected to
swing inland across central and southern oregon late tonight into
tue. This returns a chance for some showers to the far southern part
of the forecast area, mainly the lane county cascades tonight and
tue. To the north, the area will remain under a weak surface high
pres, with light winds favorable for radiational fog to develop again
in the valleys late tonight and continuing through Tue morning.

Tue night and Wed models indicate some moisture creeps up again from
the south as the closed low well off the ca coast begins to open up.

This spread chances for rain northward, and by late Wed deeper
moisture arrives bringing the prospects for more substantial rain.

As the deeper moisture spreads up from the south, warmer air
associated with it likely raises snow levels above the passes wed
night. the warmer air will be short-lived though, as a cold front
ahead of a deep trough of low pres from the gulf of alaska pushes in
wed night, adding additional lift for a wet night.

Showers will decrease behind the cold front Thu as low level onshore
flow temporarily weakens as a surface ridge of high pres moves in.

Cooler air arrives Thu as the upper trough moves closer. Thickness
values indicate snow levels to drop well below cascade pass levels
by Thu afternoon.

Long term Thursday night through Sunday... Models in good
agreement moving an upper low, with origins in the gulf of alaska,
down the bc coast Thu night and fri, then inland across the region
sat. This brings a showery and quite cool air mass across the
region. Thickness values down into the range of 522 to 525 dm fri
and Sat morning suggest snow levels well down into the coast range
and cascade foothills, with maybe some flakes seen in the higher
hills of the low elevation valley zones. Sun the upper trough is
expected to move east with weak ridging following. A weak short wave
is hinted at Mon in both the GFS and ec, so will need to hang on to
some low pops Sun and mon, with temps warming a bit, but still
likely cooler than seasonal normals.

Aviation Vfr conditions prevail this evening. Skies are clear
aside from some high clouds keug southward. High pressure and
clear skies will result in excellent radiational cooling
conditions overnight, making ifr lifr fog likely for most
terminals by sunrise Tuesday. The exception may be along the
coast, where light offshore flow may keep fog from forming. Fog
is expected to lift clear between 16z-18z Tue morning, though
light northerly flow may jam low clouds against the south end of
the willamette valley until about 20z... Similar to today.VFR is
expected Tuesday after the fog burns off.

Kpdx and approaches...VFR conditions will likely give way to ifr
or lifr fog stratus by 13z Tue morning. Fog is expected to slowly
lift during the mid to late morning hours Tuesday, then scatter
out toVFR conditions with onshore flow by 19z. Weagle

Marine Expect winds to generally remain less than 20 kt
through midweek, but could see some gusts 20-25 kt Tue afternoon
and evening as high pressure to the NW and low pressure to the
sw squeeze the local pressure gradient just a bit. Strongest
winds will be in the southern waters. Models continue to show a
more active weather pattern returning Thursday and continuing
through the weekend. Small craft advisory level wind gusts of 25
to 30 kt and seas climbing above 10 ft appear most likely during
this time. Bowen weagle

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
