.SYNOPSIS...
An upper-level trough offshore will push inland over the
weekend, bringing cooler temperatures to the area and chances
for showers. Troughing will persist through early next week,
allowing for temperatures to trend just below to near normal
with continued PoPs. Drier conditions favored midweek onward a
a ridge begins to build from the southwest.
&&
.SHORT TERM /TONIGHT THROUGH SUNDAY NIGHT/...
No major updates to the forecast this morning. Latest satellite
imagery shows stratus slowly rebuilding along the coast and
Olympic Peninsula. Expect cloud cover to increase overnight in
the interior. Previous forecast discussion follows below:
A warm, dry, and sunny day continues across western Washington.
Stratus has eroded across the area with the exception of the
northern tip of the Olympic Peninsula, and temperatures have
risen into the 70s to near 80 in spots, with 60s in areas
closest to the water. Highs are expected to reach the upper 70s
to mid 80s.
The upper level trough that has been sitting offshore will
finally begin to make its way onshore this weekend, bringing
with it increased clouds and chances for showers, mainly over
the mountains and over the western Olympic Peninsula. Most of
the interior will likely stay cloudy but dry. These conditions
will allow for high temperatures to drop below normal, in the
low to mid 70s, with 60s along the coast. Low temperatures
remain in the 50s to near 60 in the metro. This trough will also
bring stronger onshore flow, with breezy conditions across much
of the area on Saturday. Gusts up to 20-25 mph will be possible,
especially across the Puget Sound and the Kitsap Peninsula.
Winds will be a bit weaker on Sunday.
&&
.LONG TERM /MONDAY THROUGH FRIDAY/...
Upper level troughing looks to continue to remain the primary
influence across the area for the first part of the week as
several troughs pass by to the northwest. This will allow for
onshore flow to continue, with morning clouds and afternoon sun.
Temperatures will return closer to normal, with highs in the
upper 70s to near 80.
Upper level heights look to start to rise towards the very end
of the week as the upper level high over the Four Corners
region looks to begin retrograding westward, which may allow
conditions to trend drier and warmer by next weekend.

.AVIATION...
Southwest flow aloft over Western Washington today will increase
into Saturday as an upper trough offshore moves closer to the
region. Low level onshore flow will increase into this evening.
VFR conditions across the area away from the immediate coast will
lower to MVFR (50-70% chance) in most areas west of the Cascades by
Saturday morning. The coast likely sees pockets of IFR/LIFR
overnight. Ceilings will lift back to VFR across the interior
Saturday afternoon, but will likely remain MVFR near the coast with
areas of drizzle and/or light showers. Winds will primarily be out
of the southwest, but increase Saturday for most terminals with
gusts up to 20 kt.
KSEA...VFR into this evening. There`s a 60-70% chance of MVFR
ceilings arriving Saturday morning from roughly 12Z-18Z. Surface
winds light westerly this afternoon will back to S/SW tonight and
rise 9 to 13 knots toward daybreak with a few gusts to 20 kt.

.MARINE...
A weak surface trough will remain over the offshore waters
into Saturday as weak surface ridge shifts inland tonight
into Saturday. This will lead to an increase in onshore flow with
small craft advisory conditions developing in the central/east
strait. A broad area of low pressure will remain offshore into early
next week with a couple of weak fronts reaching the waters Sunday
and again on Tuesday. Winds will rise across the coastal waters on
Saturday ahead of the first front for increasing southerlies and
choppy seas.

.FIRE WEATHER...
No fire weather concerns for the next seven days. Upper level
troughing over the area this weekend will send in chances for
light rain showers, but wetting rains are unlikely for most. The
best chances are over the western Olympic Peninsula. However,
this will keep the airmass seasonably cool and moist through the
weekend. More seasonable temperatures are expected next week.
