.SYNOPSIS...
Cloudy skies and cooler temperatures will continue for the majority
of this week with a broad upper level trough over Western
Washington. Weak weather systems will move through the area
throughout the week, bringing chances of showers primarily for
the mountains. A warmer and drier pattern is favored to develop
this weekend.

&&

.SHORT TERM /TONIGHT THROUGH TUESDAY NIGHT/...
A broad upper level trough will remain over the Pacific Northwest
for the majority of the week, allowing weak disturbances to
pass through the region. The majority of locations are expected
to remain dry and the highest chances for showers will be
limited to the mountains. Overcast skies in the morning and
below normal temperatures this week, with temperatures generally
in the 60s and low temperatures in the low 50s. May see some
breaks in the clouds in the afternoon, but generally expect
skies to remain fairly cloudy, especially along the coast. 29

&&

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
Cloudy skies and below seasonal temperatures will continue into the
latter part of the week as long term guidance is in good agreement
in keeping the broad trough over the Pacific Northwest through
Thursday. A shift in the weather pattern is favored starting Friday
as the majority of ensemble members highlight an upper level ridge
building offshore in the Pacific. While there is uncertainty
regarding the intensity of the ridge and axis location, the
majority of members are in good agreement that Western
Washington will be under the influence of a ridge this weekend.
This will trend towards warmer temperatures and drier
conditions. 29

.AVIATION...
Ceilings have been slow to lift this afternoon with a mix of VFR
and MVFR. Guidance continues to suggest improvement for the
interior terminals this afternoon (now looking after 22z) and
conditions rebounding to VFR. There is moderate to high chances
(50-70%) for MVFR cigs to return tonight/Monday morning after
06z-09z. In addition, there is a slight chance (15-25%) for IFR
cigs between 11z-17z for Puget Sound terminals. Improvement to
VFR expected for interior terminals after 22z-23z. Southwesterly
winds 6-13 kt this afternoon for the interior terminals and
more west-northwesterly along the coast/Strait of Juan de Fuca.
Breezy winds this afternoon south of BFI, with gusts to 15-18
kt.

KSEA...MVFR cigs continue to slow lift this afternoon, but still
expecting VFR conditions this afternoon. There is moderate
confidence (50-70%) for MVFR cigs to return as early as 09z
Monday and low confidence (15%) for IFR cigs between 13z-17z.
Improvement to VFR likely after 22z. Southwesterly winds
generally between 6-10 kt through the TAF Period. Breezy winds
this afternoon with gusts generally around 15 kt. 29

.MARINE...
The dominant weather feature will involve broad high pressure over
the Pacific and lower pressure over the interior that will promote
onshore flow through the week. This will lead to gusty
northwesterlies over the coastal waters and steep, choppy seas.
In addition, the central and east portions of the Strait of Juan de
Fuca will likely see diurnally driven increases in westerlies that
may reach small craft advisory strength at times. A small craft
advisory is set to go into effect this evening. Wednesday looks to
be the next strongest push, with probabilities around 45-65% of
winds exceeding 21 kt. The offshore ridge looks to weaken late this
week for lighter winds and subsiding seas.

&&

.FIRE WEATHER...
Little in the way of fire weather concerns remain in the
picture well into the week ahead with upper troughing
maintaining cool conditions, high RH, and periodic chances for
shower activity. A trend toward more seasonable temperatures is
indicated toward late week, but a significant warm and dry spell
is not expected in the next 7 days.
