Synopsis A weak north to south moving weather system will brush
the coast today with clouds and a threat of light rain for the coast
and olympics. Another weak system Sunday night and Monday moving
into british columbia should bring more clouds and a chance of light
rain to mainly northern portions of the area. Higher pressure aloft
is expected to build offshore Tuesday into mid week for a return to
sunshine and warmer temperatures.

Short term Current radar shows some showers along the coast this
early morning... Along with a little blob of showers passing over the
san juans at the time of this writing. Models have been pretty
consistent in keeping this activity west of puget sound and aside
for the minor deviation that is the aforementioned blob over the san
juans... Would expect activity today to be limited to the coast and
the olympics. Current satellite reveals nothing in the way of
surprises as the area is pretty socked in with clouds.

Feels weird to say that this is all associated with a slow moving
upper level ridge nudging its way into the area... But there it
is... A dirty ridge if there ever was one. Enough moisture looks to
be over the area for a generally cloudy weekend... Although some
breaks of Sun look to emerge this afternoon east of the sound.

Sunday will see a return of widespread clouds as an embedded
shortwave within the ridge looks to move through the area on
Monday... Bringing with it a returning chance of showers for most of
the area.

But a ridge is still a ridge... Which means the steady warming trend
that models have been advertising the past several runs looks to
remain on track. Widespread highs in the 60s today... With some
locations possibly hitting 70... Will continue to gradually increase
a degree or two for Sunday. The aforementioned shortwave looks to
knock temps down slightly for Monday... But even then high temps in
the mid 60s will be pretty widespread. Although this is slightly
below normal... All in all a pretty cozy start to fall. Smr

Long term It is pretty safe to say that Tuesday is where the
ridge gets its groove back and sheds the dirty moniker. While clouds
will gradually erode throughout the day... The standout will be the
high temperatures as they rise once more to around the 70 mark for
many locations. With clear skies holding court over W wa for the
remainder of the work week... Conditions will continue to warm with
temps peaking on Thursday as many locations find themselves in the
upper 70s. The ridge exits soon afterward and W wa as models start
to coalesce on a solution for Friday and into the weekend of an
upper level trough starting to enter the area. This will bring temps
back down to around 70 in most spots. Models still disagree with
whether or not this will result in precip though... As the GFS proves
the wetter solution bringing precip area-wide while the ECMWF limits
any pops to the northernmost portions of the area. Leaning toward
ecmwf solution at this time. Smr

Aviation Western wa lies in between a trough over the
intermountain west and a ridge offshore. The flow aloft is
northerly. The air mass is dry and stable with mainly mid-high
level clouds over the region. Patchy fog or low clouds may form
early this morning, mainly in the valleys and along the coast.

Light rain is possible along the coast where there is weak warm
air advection. The interior will remain dry. The ridge will shift
inland tonight for dry conditions. 33
ksea... Patchy low clouds or stratus may form early this morning
for brief MVFR conditions. Otherwise, light south winds andVFR
with dry conditions. Surface winds will flip to light northerly
03-06z tonight. 33

Marine High pressure over the NE pacific will maintain light
onshore flow this weekend. A warm front will clip the area on
Monday with possible small craft advisory winds over the coastal
waters. The flow will turn offshore by midweek as a thermal trough
forms along the coast. 33

Sew watches warnings advisories
Wa... None.

Pz... None.
