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 continue to spread
showers across the oregon cascades this afternoon and evening,
possibly affecting the eastern edge of the willamette valley. Onshore
flow will continue through Saturday as a weak system approaches and
then passes by to the north Saturday, with a dissipating front moving
through, 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 Tonight through Monday... Southwest washington and
northwest oregon remains in between 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 radar and web cams show the band of showers extending north along
the cascades to near or just north of mount jefferson. It is possible
a few of the showers may drift off into the eastern willamette valley
before dissipating. This is in line with recent model forecasts. The
models still show it will be stable in our forecast area with any
thunder in central oregon and eastward, and with the layered clouds
on satellite imagery, this still seems reasonable as well.

Otherwise west of the cascades should be mostly dry tonight. Clouds
have thinned in the far western sections of the forecast area but
will stay rather cloudy closer to 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. Not much change on Monday as
compared to Sunday, though the models do start to lower the 500 mb
heights and increase the onshore flow a bit later in the day ahead of
the next approaching offshore upper trough. Suspect the main cooling
will be Monday night and Tuesday. Tolleson

Long term Monday night through Friday... The models show an
approaching and digging upper trough off the coast Monday night and
Tuesday, with a short wave that swings through Tuesday night and
early Wednesday. The upper trough remains in the region Thursday and
Friday through the GFS model is stronger than on the ecmwf. The main
effect is that it will be cooler, cloudier, with possibly some spotty
light precipitation especially north, though details are uncertain
later next week. Tolleson

Aviation MostlyVFR conditions across the area this afternoon.

Scattering clouds along and west of a k6s2-kkls line have improved
conditions considerably. However, moisture and associated cloud field
continues to rotate into the eastern and central portions of the
forecast area with lowVFR CIGS persisting. Meanwhile, gusty winds
across the northern half of the forecast area will develop and
persist through the late afternoon early evening. Stronger onshore
flow tonight should again bring a return to widespread MVFR cigs
first to the coast and later across the interior.

Kpdx and approaches...VFR CIGS this afternoon with some scattering
possible late this afternoon. Gusty west winds 23z-04z with gusts to
15-20 kt. Expect a return of MVFR CIGS late overnight through early
Saturday as moist onshore flow continues. Cullen

Marine High pressure remains over the northeast pacific with lower
pressure over northern california. This will maintain north to
northwest winds across the coastal waters through the weekend and
into the start of next week. Gusts should remain generally between 10
and 20 kt with seas holding between 5 and 7 feet. Buoy 46050 recorded
gusts meeting advisory criteria for several hours, but these have
largely come to an end. Therefore, have cancelled the advisory a few
hours early, though a few occasional gusts around 20-25 kt cannot be
entirely ruled out. Northerly winds will likely increase during the
early to middle part of next week (perhaps as early as late Sunday
night or Monday), which will likely create steep and hazardous seas.
