.SYNOPSIS...
A low pressure system is on track to bring rain, breezy winds,
and chances for thunderstorms to the region on Monday. Showery
weather continues on Tuesday, with a return to high pressure
likely later in the week.

&&

.SHORT TERM /TONIGHT THROUGH TUESDAY NIGHT/...
The next system is not too far offshore with clouds already
starting to move in over Neah Bay and the leading. Most all the
area should remain mostly sunny through the rest of the day
with clouds increasing overnight. Highs should reach the upper
60s with a few low 70s in some spots.

Rain will start to move in along the coast early Tuesday morning
before filling in across the interior after sunrise and into the
late morning. Winds will also start to increase in the morning,
with the peak winds expected late morning/early afternoon as the
frontal system traverses the area. Wind gusts up to 25-35 mph
will be possible for most, through for the coast and areas
around/north of Whidbey Island, gusts up to 35-40 mph can`t be
ruled out. Behind the front, rain will devolve into scattered
showers and a few isolated thunderstorms. The best chances for
thunderstorms will be along the coast and across SW WA Monday
afternoon and early evening, with probabilities of around
15-20%. With the rain, highs will be much cooler, in the upper
50s to low 60s.

Unsettled weather continues into Tuesday as the low center
moves through the area. Scattered showers and a few isolated
thunderstorms remain possible throughout the day. Highs a touch
warmer, in the low to mid 60s.

Unseasonably large waves will begin to arrive at the coast late
on Monday, before peaking early Tuesday morning to around 14 to
16 ft, bringing high surf conditions to the coast. Waves will
slowly decrease throughout the day Tuesday.

&&

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
The low pressure system responsible for Monday and Tuesday`s
weather will continue to dig south, leaving the PNW in split
flow to gentle ridging into the mid and late week. As such,
temperatures begin to warm from Wednesday onward, reaching highs
back into the mid 70s by Thursday. Ensembles and deterministic
guidance are hinting at broader troughing over the NE Pacific
late in the week for potential for more unsettled weather. Low
pressure over the intermountain west will also begin to drift
northward, pushing moisture from the east side over the
Cascades, with chances for showers beginning Thursday through
the end of the week. Upper level troughing over the area may
provide enough instability for a slight (10-15%) chance of
thunder over the mountains as well.

Long period swell will arrive to the coast on Thursday, which
will pose a bigger threat for significant wave runup on coastal
beaches as well as the potential for minor erosion.

.AVIATION...
Increasing high clouds are spreading into the region this
evening as the next frontal system advancing toward the
coastline. Expect southerly surface winds around 5-7 kt and
primarily VFR ceilings, but beginning to gradually lower early
tonight into Monday. Coastal conditions dip first, with MVFR
arriving toward 09z and a likely (70+% chance) of IFR from 12z
onward in increasing rain.

Conditions look to be a bit slower to drop across the interior,
with guidance favoring VFR ceilings into at least early
morning, before lowering into the MVFR category as rain increases
and the lower air mass saturates. Southerly winds will increase
across the area Monday morning as the system approaches, with
gusts to 20-30 kt, strongest along the coast and interior areas
from around KPAE northward. Mix of MVFR/VFR ceilings likely
remain in the interior through much of the day as rain showers
continue. Low likelihood (10% or less) for a thunderstorm near
the coast or south of Puget Sound late Monday afternoon, but
confidence too low for TAF inclusion.

KSEA...VFR conditions with southerly winds around 7 kt will
prevail this evening with increasing clouds and gradually
lowering ceilings. Rain expected to move into the terminal
between 16-18Z Monday as a frontal system moves into the area,
with increasing southerly winds with gusts to 20-25 kt by mid
morning through much of the day Monday. 15-20% chance of MVFR
ceilings for a few hours around 20z with heaviest rain, but
ceilings around 4000-4500 ft remain most likely.

.MARINE...
A low pressure system will begin to move through the area
tomorrow, with a cold front traversing the area waters through
the morning and afternoon hours. Southerly winds will increase
early tomorrow morning ahead of the front. Most of the coastal
waters will see high-end Small Craft Advisory winds, but gusts
to gale force will be possible over the northern-most areas, for
which that has been upgraded to a Gale Warning. Through the
interior coastal waters from Puget Sound up through the Northern
Inland Waters, winds will increase slightly later in the
morning and persist into the afternoon as the front moves
through. Probabilities have decreased for gale force gust across
most of the interior coastal waters, but a few gusts to gale
cannot be ruled out in the East Strait of Juan de Fuca (30-60%
chances).

Winds will decrease but still remain elevated through much of
the day. It isn`t until Monday night into Tuesday when winds
begin to calm down across the area as the low pressure center
moves across the region.

High pressure quickly rebuilds as the system departs on Tuesday,
with winds switch back to north/northwesterly Tuesday morning
and increase to SCA criteria through the outer coastal waters
by Tuesday evening. This pattern looks to persist through the
end of the week. Beginning Thursday, lower pressure over land
will increase the onshore gradient, funneling wind through the
Strait of Juan de Fuca. Winds increase during the day,
potentially reaching gale force by Thursday evening and into
Friday.

Seas 5 to 7 ft will increase through the day Monday, peaking up
to 14 to 16 ft Monday night into early Tuesday. Seas will slowly
decrease throughout the day Tuesday and may briefly drop to
around 8 to 10 ft on Wednesday before climbing back up to around
10 to 12 ft Thursday.

Steep seas through the outer coastal waters will likely return
Tuesday night into Wednesday as the local winds increase and the
dominant period decrease to around 8-10 seconds. Long period
swell 7 to 10 ft with a period of 15-18 seconds will arrive to
the coast on Thursday, pushing the significant wave height back
up above 10 ft. Waves look to start to ease on Friday below 10
ft.
