and/or seas 10 feet or higher are expected to produce hazardous
wave conditions to small craft. Inexperienced mariners,
especially those operating smaller vessels should avoid
navigating in these conditions.

Area Forecast Discussion
National Weather Service Seattle WA
858 AM PDT Sat Aug 28 2021

.UPDATE...Satellite showing some areas of patchy fog across the
region this morning, primarily along area waterways and in
portions of the north and central Cascades. Trends already show
the thin layer of fog dissipating, so expect conditions to clear
out by late morning for the majority of the interior. The
exception could be some stratus and patchy fog lingering along the
coast this afternoon. Otherwise, expect sun for areas across the
interior today as shortwave ridging traverses the region. Afternoon
highs along the coast are expected to remain in the 60s, while
highs across the interior climb into the mid to upper 70s. A few
spots across the Chehalis river valley could hit 80. Only minor
tweaks made to the forecast this morning to account for the extent
of the patchy fog. The previous discussion follows below, with
updates made to the aviation section. 14

.SYNOPSIS...Dry and warmer conditions expected this weekend as high
pressure builds over the area. A return to cooler and cloudier
weather expected early next week as we fall into a general unsettled
weather pattern.

&&

.SHORT TERM /TODAY THROUGH MONDAY/...Upper level ridging will
continue to move into the area today. This ridge does not linger
for very long as it will flatten throughout the day and pass over
into E WA by early this evening. Still, this will result in warmer
temperatures today with upper 60s along the coast and most of the
interior lowlands getting up into the mid to upper 70s.

A more zonal influence expected for Sunday as an upper level trough
passes well to the north of the area in northern BC. This should
have little impact to the area save for taking the edge off
afternoon highs, with the coast dipping a bit into the mid 60s while
the interior will typically see mid to upper 70s for the southern
half, lower to mid 70s for the northern half. Monday sees the
aforementioned trough start to dig southward and while deterministic
models have some precip near the area or maybe some isolated patches
within the CWA, ensembles maintain a dry forecast...and will opt for
that solution in the forecast. The main impact will be cooler
temperatures returning to W WA...with afternoon highs for coastal
locations dipping down into the lower 60s while the interior drops
into the mid 60s to around 70.

.LONG TERM /TUESDAY THROUGH FRIDAY/...Deterministic models deviate a
little bit here as the ECMWF keeps the upper level low at the core
of this trough still to the north of the Canadian border while the
GFS brings it further south into WA. In terms of precip chances
however, the two agree that W WA should remain generally dry Wed and
Thu. Serious disagreements in the deterministic models and a high
level of uncertainty in ensembles arise for Friday. GFS deepens the
trough even further with the upper level low dipping down into
northern CA. ECMWF, however, starts to build a ridge over the area.
Both models agree that whatever happens, the area should remain dry.
Most ensemble members trend this way as well. As such, not a whole
lot of confidence toward the end of the extended except to say that
it will likely remain dry.

Will see a gradual warm up over the area as high temps Tuesday will
only be a degree or two warmer than Monday before climbing a bit
more significantly on Wed, with coastal sites getting into the mid
60s while the interior sits solidly in the lower to mid 70s. The
remainder of the long term gets a bit warmer with around 70 for the
coast and mid to upper 70s for much of the interior both Thursday
and Friday.  18

.AVIATION...High pressure will keep the Western Washington area
dry for throughout the weekend. As of 1500 UTC some fog remains in
some of the valleys, but is quickly mixing out this morning.
Clear skies are expected for the rest of the day. Marine stratus
is expected to move back inland starting after 1200 UTC Sunday.
Low clouds and fog should once again mix out fairly quickly after
sunrise. Winds throughout they day will remain north/northwesterly
and will pick up to 7-10 knots this afternoon.

KSEA...Mostly clear skies will remain in place through today.
Winds will gradually pick up to around 10 knots by this afternoon
(around 0000 UTC). Winds are expected to remain northwesterly
through the day before easing during the night as the marine layer
moves in.

.MARINE...High pressure over the NE Pacific will maintain breezy
northwest winds over the coastal waters, west winds through the
Strait of Juan de Fuca and northerly winds through Puget Sound.
Winds will be strongest each afternoon and evening. While winds are
expected to remain generally below advisory criteria, could see some
gusts to 25 kt (along with steep seas) over the coastal waters south
of around Point Grenville this afternoon and especially Sunday
afternoon. Similarly winds through the Strait will generally be to
20 kt, through the windiest spots may occasionally reach 25 kt.

Seas over the coastal waters remain 5 to 7 ft and largely comprised
of a locally generated fresh swell. The next front reaches the
waters around Monday, bringing stronger westerly winds to the
coastal waters and a likely advisory-strength push of west winds
through the Strait.
