.SYNOPSIS...
A strong and stable ridge will remain in place throughout the
rest of the week and into early next week. Periods of stratus
and patchy fog will occur through then. East to northeast flow
will strengthen into Friday, helping to erode some of the
stratus that has been around for the last several days.
&&
.SHORT TERM /TONIGHT THROUGH SATURDAY NIGHT/...
The ridge will remain in place throughout the short term. A
passing disturbance to the east will kick up the ENE winds
overnight into Friday morning, but will remain below any sort of
advisory thresholds. Gusts between 15 to 20 mph will be possible
by Friday morning. Given the warmer and drier nature of these
winds, it will help to keep most of the stratus out of eastern
Puget Sound, though indications as of now are that patches of
stratus and fog may still linger through Olympia and as far
north as Tacoma into Friday morning.
The ridge will shift slightly more overhead over the weekend,
favoring clearer skies and less of a stratus intrusion. With
that, temperatures will be somewhat cooler, with highs in the
low 50s and lows dipping into the mid 30s.
&&
.LONG TERM /SUNDAY THROUGH THURSDAY/...
The extended forecast also remains largely dry and still
influenced by the ridge pattern. Winds look to remain light and
at times, offshore. Some light QPF is finally in the grids on
Thursday of next week, but even now, that comes with little
certainty.

.AVIATION...
An upper level ridge pattern will remain in place
through Friday with light N/NE flow. An MVFR deck remains in the
interior terminals this afternoon, with satellite showing
dissipation at the north side of the deck working its way south.
Another low deck is also eroding on the coast (from Forks to
Clearwater). NE winds at 5-10 kt will continue through the afternoon
(with gusts up to 20 kt in the interior at times and portions of the
Pacific Coast). Probabilities for fog/low stratus for Friday morning
remain medium. Areas with light winds will have the greatest chance
of seeing development (foothills of the Cascades, especially in the
Everett and Tacoma/Olympia areas). Stratus that remains into the
afternoon/evening will drop fog probabilities for Friday morning.
KSEA...MVFR deck remains overhead, but will partially scatter from
22-23Z this afternoon. NE winds 5-10 kt with a few gusts to 20 kt.
Probability for fog Friday morning remains at 20-30% (but is higher
to the north and south of the terminal). Probability is conditional
on cloud coverage clearing this afternoon/evening, and winds
remaining light enough Friday morning for formation. Otherwise, IFR
conditions appear more favorable if low cigs/vis develop.

.MARINE...
High pressure offshore remains with a thermal trough along
the coast keeping the flow offshore. Breezy east wind gusts up to 25
kt will be possible in the west/central Strait of Juan de Fuca and
the northern inner coastal zones (where a small craft advisory
continues). Few gusts to 20 kt are possible in the waters off of
Ocean Shores. Otherwise, no significant winds are expected after
Friday through Wednesday. Seas will remain at 4-6 ft today through
Wednesday.
