Synopsis A surface ridge offshore will maintain an onshore flow
pattern over western washington through this weekend with morning
low clouds and afternoon sunshine and temperatures near or a little
above normal. An upper level ridge will move over the area Thursday
and Friday for a brief warmer period. A weak front may brush the
area with more clouds and possibly a few showers later this weekend.

Short term A weak upper level trough moving across the region
this evening is still bringing some mid and high level clouds to the
south half of W wa. There was still a little bit of stratus along
the central wa coast. Quite benign compared to the hammering the
upper level trough has been giving SE wa from severe thunderstorms.

This benign pattern will continue for W wa this week, dominated by
the surface ridge presently centered about 750 nm offshore near
140w. This ridge will maintain a typical mild onshore flow pattern
across W wa through this weekend, modulated by the upper level
pattern. A low amplitude somewhat broad upper level trough will be
over the region through Wednesday. This will allow the onshore flow
to be a little stronger Tuesday and Wednesday which will produce
more morning low clouds and cap high temperatures in the lower to
mid 70s. The marine layer will remain moist enough to allow low
stratus clouds to reform late tonight and again Tuesday night, with
more complete coverage across the W wa lowlands than this morning.

Burn-off should be about the same each day, 18z-19z 11 am-noon,
leaving mostly sunny skies in the afternoon. The stratus will take a
little longer to clear from the coast and some spots along the
coastline may only get some brief afternoon clearing.

An offshore upper level ridge will be slowly approaching the region
through Wednesday, finally reaching about 250 nm offshore near 130w
Thursday morning. The ridge will weaken the onshore flow and provide
a little more warming, allowing high temperatures to reach the mid
to upper 70s Thursday followed by highs in the lower 80s on Friday.

Continuing but weaker onshore flow should produce less morning
stratus Thursday and Friday mornings, but burn-off will likely still
occur later in the morning. Kam

Long term Previous discussion from the 348 pm afd... Medium range
models models remain in good agreement through Friday, showing the
upper ridge axis overhead around midday Friday. This will make it
the warmest day of the week, however low level onshore flow and
morning clouds will continue to limit the warming. Temperatures will
rise into the low to mid 80s through parts of the interior, and
remain in the mid to upper 60s along the coast and strait. Models
still begin to differ on the details Saturday onward. The ECMWF and
canadian models continue to be a little more aggressive with a
system moving from the gulf of alaska into british columbia
Saturday, while the GFS continues to be much weaker with this
system. The GFS continues to keep the area dry through Sunday while
the ECMWF and canadian bring a chance of showers to western
washington late Saturday night into Sunday. For now the forecast
leans towards the majority forecast, with a slight chance of showers
Saturday night through Monday - mainly for the northern portion of
the forecast area. Highs will cool back down to near normal, as the
Fridays upper level ridge shifts to the east and low level onshore
flow stays in place into early next week.

Aviation A very typical pattern of morning clouds and afternoon
sun is expected for the interior of western washington over the next
few days. The coast from about hoquiam south had marine layer
stratus for most of the day today, and it has already started to
push back in. The air mass is stable. Southwest flow aloft will
become northwest on Tuesday.

Ksea... Morning clouds and afternoon Sun are on tap for Tuesday--the
southerly breeze will probably turn around to the northwest for the
late afternoon and evening hours.

Marine High pres offshore with lower pres E of the cascades will
result in onshore flow of varying strength this week. The flow is
strong enough for a gale warning in the central and eastern strait
or juan de fuca again this evening.

Sew watches warnings advisories
Wa... None.

Pz... Gale warning until midnight pdt tonight for central strait of
juan de fuca-east entrance strait of juan de fuca.

Small craft advisories are in effect for parts of the coastal
waters, west entrance to the strait of juan de fuca, and
admiralty inlet.
