What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis A low over northern california will spread showers across
the central oregon cascades and possibly the south interior today.

Onshore flow will continue through Saturday as a weak system
approaches then passes by to the north Saturday, with a dissipating
front, possibly producing some drizzle or light showers late tonight
and Saturday. A return to dry weather and slightly above normal
daytime temperatures can be expected Sunday into early next week with
a more seasonal night and morning clouds regime. The next weak upper
trough is expected around the middle of next week with increased
onshore flow, cooler temperatures, and spotty precipitation.

Short term Today through Sunday... Southwest washington and
northwest oregon is in the middle of two systems. The first system is
an upper low now over northern california that has been the main
driver of our recent showers and thunderstorms over the cascades.

This system is currently spreading showers under a deformation zone
north of the low. National weather service doppler radar shows that
the main precipitation is in southwest oregon similar to the models,
but model forecasts suggest that some of this precipitation will
spread north into eastern lane county and toward mount jefferson this
afternoon. This seems reasonable and will be continued in the morning
update. The models still show it will be stable in our forecast area
with thunder in central oregon and eastward, and with the layered
clouds on satellite imagery, this still seems reasonable as well.

West of the cascades should be mostly dry unless a few showers clip
the eastern valleys areas. Clouds will be persistent today, though
they may thin a bit later this afternoon and evening west of the
cascades.

The low to our south will move slowly eastward tonight and Saturday
as a weak system moves through to our north tonight and Saturday. The
models show a dissipating frontal boundary with this northern system
moving into and through our forecast area, and this is likely the
reason why the models are producing some light drizzle or showers
mainly near the coast and inland to around kelso late tonight and
then over much of the inland areas Saturday. QPF will be light and
pops will be kept low, though we have some low chance pops in some
areas. This will also keep clouds around through the day Saturday,
especially in the inland areas.

A positive tilt upper ridge builds in Saturday night and Sunday,
transitioning the weather to a more typical or seasonal night and
morning clouds afternoon sunshine regime. Temperatures on Sunday will
be rising back into the mid 70s. Tolleson

Long term No changes. Previous discussion follows...

Sunday night through Thursday... The models are in good agreement with
a positive tilt upper ridge over the pacific northwest from Sunday
continuing over the forecast area on Monday. The net result will be
afternoon sunshine after areas of night and morning low clouds.

Temperatures will likely trend back toward or perhaps slightly above
normal. The models then show an upper trough swinging through in the
mid week period with increased onshore flow, possibly some spotty
light precipitation, and temperatures again dropping a bit below
normal. Tolleson

Aviation Mix of MVFR toVFR conditions across the area this
morning. Expect improvement to predominatelyVFR conditions across
the interior after 18-19z. However, a mix of MVFR toVFR conditions
continues along the coast through the day. Expect some gusty winds
across the northern portions of the willamette valley this afternoon
and into the early evening. Stronger onshore flow tonight should
again bring a return to widespread MVFR CIGS inland and at the coast.

Kpdx and approaches... MVFR CIGS for the next few hours will become
vfr after 19z. Gusty west winds 23z-04z with gusts to 15-20 kt.

Expect a return a MVFR CIGS late overnight through early Saturday as
moist onshore flow continues. cullen

Marine High pressure over the northeast pacific and lower pressure
over northern california will maintain N to NW winds across the
waters for much of the next week. Wind gusts should generally remain
between 10 to 20 kt and seas in the 4 to 7 ft range through the
weekend. Winds over the southern waters south of cascade head, will
continue to flirt with small craft advisory for wind criteria today,
so will go ahead and issue an advisory. Northerly winds will likely
increase during the early to middle part of next week beginning as
early as Sun night or mon, which will likely create steep and
hazardous seas.

Pqr watches warnings advisories
Or... None.

Wa... None.

Pz... Small craft advisory for winds until 7 pm pdt this evening for
coastal waters from cascade head or to florence or out 60
nm.
