.SYNOPSIS...
Just a few post frontal showers today for Western Washington
with the area in between systems. Next system arriving Monday
night with a warm front right behind it Tuesday. Warm front
lifting north Tuesday night. Trailing cold front stalling
offshore Wednesday producing possible record high temperatures.
Cold front getting stretched out Wednesday night with an upper
level trough digging south offshore. What is left of the front
moving through Thursday night. An atmospheric river will set up
over Western Washington Friday and Saturday.

.SHORT TERM /TODAY THROUGH TUESDAY/...
Quick hitting cold fronts like the one Saturday night almost
always cause trouble. Calmer weather today across the area with
post frontal shower activity drying up this afternoon. Still
breezy in some locations this morning but winds aloft are easing
quickly and onshore surface gradients are weakening. Under
mostly cloudy/partly sunny skies temperatures will not warm up
much from the current readings with highs in the mid 50s.
Even though the winds have eased post frontal high surf
will keep dangerous conditions present along the beaches. The
high surf warning will remain in effect today.
Temporary upper level ridge moving through the area tonight.
Low level flow going offshore with the approach of the next
weather system. Some clearing overnight will allow temperatures
to drop into the mid 30s in the colder locations. Most places a
couple of degrees either side of 40. Seas subsiding overnight
into the 15 to 18 foot range. Current forecast has the high
surf warning expiring at 10 pm tonight.
Next frontal system approaching Western Washington Monday.
Parent low for the front well up into the Gulf of Alaska and
moving north northwest. This will stretch out the front and
cause it to become more north south oriented slowing down the
eastward movement of the system. Rain reaching the coast early
afternoon and over the interior by the Monday afternoon commute.
Highs again in the mid 50s.
Front slowly moving through Western Washington Monday evening
with rain coming to an end after midnight. Windy conditions
along the coast and over the Northwest Interior ( but nothing
like we had Saturday ). Lows in the mid 40s to lower 50s.
Next system moving quickly across the Pacific has a long fetch
of moisture with it, all the way back to 35N/150W. IVT values in
the 800-1000 km/m/s range, some of the higher numbers we have
seen so far this season. Rain moving back into the area during
the day. Highs in the mid 50s. Felton

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
Extended models showing good consistency lifting Tuesday`s warm
front to the north Tuesday night. Trailing cold front stalling
off the coast Wednesday as a deep upper level trough digs south
behind the cold front. This scenario puts Western Washington in
the warm sector Wednesday with record highs, in the lower to mid
60s, possible.
Cold front stalled offshore Wednesday night getting stretched
out and weakened as the trough continues to dig south. What is
left of the front moving inland later Thursday into Thursday
night.
Flow aloft consolidating offshore Friday with an atmospheric
river setting up over Western Washington for more rain. Another
upper level trough will dig south off the coast Friday night
into Saturday. This trough will be a little further east than
the one earlier in the week. This has the potential to pivot the
atmospheric river right over Western Washington keeping rain
going Friday night into Saturday.
Snow levels remaining elevated during the extended period with
snow confined to the higher elevations well above pass levels.

.AVIATION...
Scattered showers continue across the area this morning in a
post-frontal environment. Terminals are mostly VFR, though
could briefly see a drop to MVFR at times in any heavier shower
activity this morning. Terminals have also been reporting a
scattered deck between 2000-2500 ft. Cloud coverage will slowly
decrease throughout the day, though high clouds will continue
to stream in overhead. Showers will also taper throughout the
day, though latest hi-res guidance hints at a brief convergence
zone setting up across Snohomish County this afternoon. Winds
have peaked across the area but remain breezy around 15-25 kt
this morning. Winds will start to ease below 10 kt between
18-21Z this morning, then below 5 kt after 03Z Monday. Offshore
flow will start to increase around 12Z Mon.
KSEA...Mostly VFR conditions through the TAF period with a 20-30%
chance of occasional MVFR cigs in heavier showers. Showers and
lower level clouds will start to decrease after 18-21Z this
morning. South to southwest winds around 15 kt with gusts to 25
kt will slowly decrease today, with easing gusts and winds
around 10 kt after 18Z this morning, becoming around 5 kt or
less this evening. Winds will become more easterly after 06Z
Monday.

.MARINE...
Winds remain breezy across the area waters this morning, but
will continue to ease over the next few hours. This will bring
a brief period of calmer winds to the waters through late
tonight before the next frontal system begins to move across the
coastal waters on Monday. Winds will begin to increase again
early Monday morning, peaking in the afternoon as the frontal
system traverses the area. Additional headlines will be likely
for all area waters, though Gale Watches remain in place for
the coastal waters and East Strait of Juan de Fuca where
confidence is highest in gale force gusts (50-80% chc). Winds
will decrease again Monday evening but not for long as another
system will be on its heels for another round of stronger winds
overnight Monday and throughout the day Tuesday. Additional
frontal systems will move through the waters mid to late week,
likely bringing more rounds of widespread headlines to the area
waters.
Seas continue to increase this morning and are expected to top
out in the 20-25 ft range this afternoon. Seas will subside tonight
into Monday to around 12-15 ft before the next system brings
seas back to the 16-18 ft range on Tuesday. Seas will lower and
rise through mid to late week but remain above 13 ft through the
end of the week, with the next best chance for seas above 20 ft
over this weekend.

.HYDROLOGY...
River flooding is not expected the next seven days. Multiple
weather systems moving through the area in the next week. While
current precipitation forecasts are not expected to cause
flooding, this will saturate soils and raise base flows. If the
atmospheric river stalls over the area late next week into next
weekend we might need to keep an eye on our old friend the
Skokomish River. Felton
