935 am pdt Thu sep 21 2017

Synopsis An upper level trough will maintain a chance of
showers and cooler temperatures over western washington today,
mainly over the mountains and over the lowlands from seattle
southward. Drier north flow aloft from an offshore upper level ridge
will bring sunshine and a little warming Friday and Saturday. The
weakening ridge will move over the area Sunday and Monday but could
allow transient weak weather systems to bring some spotty light
rain. The ridge will build Tuesday or Wednesday for mostly sunny
weather.

Short term A large upper level trough centered over E wa and ne
oregon this morning will maintain somewhat moist n-ne flow aloft
over W wa today. Radar is picking up small showers forming over n
puget sound which are drifting S over the SW interior. This could be
just left over activity from earlier this morning as the new 12z
nam, 06z gfs, and 12z nam MOS guidance are all dry for the north
part of puget sound and the N interior today. 15z IR imagery
suggests a little reduction in the cloud cover over vancouver b.C.

And parts of the NW interior, so will go with the latest guidance
and hold off on expanding lowland showers today. Otherwise, guidance
agrees that the cascades and olympics will have scattered showers
today as will the lowlands S of the olympics,
the oregon upper level trough and the upstream upper level ridge
over the NE pacific will both slide a bit E tonight and Friday. The
flow aloft should dry enough to end the chance of showers for
everywhere except the cascades. The upper level ridge will tilt e
over southern b.C. By Saturday. There will be a lot of flow through
the ridge both Friday and Saturday which will allow mid and high
level moisture to move across W wa at times. There will be more
sunshine than today, but still periods of cloudiness. The warming
and drying from the ridge should be enough to push area high
temperatures into the lower to mid 60s, which would be just a little
below normal.

The weak upper level ridge remains in place over S b.C. On Sunday
but the models differ on whether a system moving through the ridge
will be strong enough to bring rain to W wa. The 06z GFS is the
wettest, bringing light rain to just about all of W wa. The 00z
ecmwf and 00z canadian models keep all the precip up over b.C. The
current forecast compromises between the two solutions with low
chance pops over the N part of W wa. Kam

Long term Previous discussion from the 335 am afd... The upper
level ridge persists Monday and into midweek keeping the area
relatively dry... Although each model shows a bit of moisture and
thus the potential for showers to dip south enough to be right on
the doorstep... But never really panning out. Not helping matters is
that there is really not much in the way of agreement as to which
systems or which days this will occur. Feels like a bit of a cop
out... But best course of action is to keep the forecast painted in
broad strokes with slight chance pops for much of the extended until
models can gel on something resembling a singular solution.

Regardless of precip... Should continue to see temperatures gradually
climb into the 70s for many locations for the first half of next
week. Smr

Aviation A broad upper level trough over the interior pacific
northwest will slowly migrate to the southeast through Thursday.

High pressure centered along 140w will persist, maintaining light
northerly flow aloft. The air mass is generally stable and somewhat
moist, mainly in the lower levels. Northerly flow will allow the air
mass to dry tonight and Thursday.

Cigs are variable across western wa this morning. Areas of ifr cigs
and vis are mostly affecting the southwest interior and
south central puget sound. Residual showers are also causing some
ifr conditions at the ksea kbfi terminals and pwt (bremerton).

Conditions should improve to mostlyVFR by midday and scatter out
this afternoon.

Ksea... Light southwest flow to 5 kt will become north-northwest by
early this afternoon. Northeast flow just above the surface and low
level moisture will cause ifr CIGS W showers as late as 18z.

Conditions should improve toVFR by midday and clouds will scatter
later in the day.

Marine Weak surface low over interior western wa will move
east of the cascades today. Another weak low will move south through
the coastal waters later tonight and Thursday. High pressure
building on Friday with high pressure remaining over the area into
the early part of next week. Winds are forecast to remain below 20
knots across the waters. Dtm

Sew watches warnings advisories
Wa... None.

Pz... None.
