Synopsis A frontal system will move through western washington
later this afternoon and this evening. The low associated with the
front will move inland well to the north of the area. High winds
will be confined to the coast and portions of the northern
interior. A little break between systems is expected on Saturday.

The active weather pattern will resume Sunday with additional
weather systems reaching the area through the middle of next week.

The systems from Monday through Thursday of next week will likely
bring locally heavy rainfall and windy conditions at times.

Short term tonight through Monday Observations show the
incoming strong frontal system moving through the coastal waters
this afternoon. A brief period of strong winds was reported at
hoquiam and buoys over the coastal waters are reporting strong
winds at this time. The areal coverage of the strong winds is
rather small, with occasional winds or gusts lasting for about 2
hours or so from onset to frontal passage. In the interior winds
will suddenly increase from the S or ssw with the front and will
last for a couple of hours behind the front. Pockets of high wind
are expected near the water over portions of the northern
interior, while the remainder of the interior from about everett
southward sees winds 5-10 mph short of high wind criteria. A burst
of westerly winds just shy of high wind criteria is expected to
develop and last a couple of hours behind the front through the
strait of juan de fuca.

High wind warnings continue for the coastal zones, western whatcom
county, the san juan islands, and the admiralty inlet area into
early this evening while wind advisories are in effect for the
remainder of the lowlands. Mountain wave wind conditions that
produced some damage over the port angeles area has ended.

The incoming front is not impressively wet and is progressive in
nature. Expect shower activity behind the front this evening to
come to an end late tonight or very early on Saturday.

Behind the front, expect a break in the weather on Saturday with
mostly cloudy conditions and only a small chance of showers in a
few areas.

The next frontal system will move slowly onshore across the area
on Sunday. This system will be weakening and splitting as it moves
inland, but it will produce some rain and locally windy
conditions. Post frontal showers will linger Sunday night into
early Monday with a possible, but difficult to time, break between
systems Monday afternoon. Albrecht

Long term Monday night through Friday A strong frontal system
associated with a possible atmospheric river will affect the area
starting Monday evening and continuing through Tuesday night.

Models continue to show the strong potential for heavy rainfall
amounts with this frontal system as the air mass originates from
around hawaii and is moist and warm. The front will pass just
south of the area Tuesday night or early Wednesday then will
likely wave north. The front will likely then pass or move south
of the area Thursday or Friday. Model details have become more
sketchy and confidence in the details starting on Wednesday is not
high.

Blended models were used in todays extended forecast. Albrecht

Aviation A strong storm system is beginning to affect the
airfields this afternoon, with strong winds and widespread rain
showers located in the vicinity of the system's frontal boundary.

Currently, cold front is in the vicinity of the coastline with
rain showers affecting hqm and the clm vicinity. This trend will
push east thru the evening with the wind following closely.VFR
cigs are likely to drop down to MVFR in the rain with some vsby
reductions possible. Winds will be out of the south with gusts
generally 20- 30kts. As the front clears the area tonight, winds
will become more SW and relax somewhat. Should see a break for
much of Saturday with CIGS expected to be largelyVFR.

Ksea...VFR conditions to continue for most of this TAF cycle,
although could drop down to MVFR in heavier rain showers with some
slight reductions to vsbys. Winds are expected to become noticeably
gustier from the south, with gusts to 30kts or so possible thru this
evening. As winds at the sfc continue to increase, wind shear
concerns will lessen. Rain will taper tonight as system exits with a
break in store for Saturday. CIGS should remainVFR with winds
continuing from the south generally 8-12kts without the gusts.

Marine Strong, amplified trough is arriving along the
coastline this afternoon and will continue to push thru western
washington this evening. Widespread rainfall and strong winds remain
the primary hazards with this system
wind observations this afternoon are indicative of gale force winds
across the coastal waters-with destruction is showing a few reports
of 50kt+. Through this evening, sporadic winds to storm force remain
possible but overall should remain largely gale. Elsewhere,
headlines remain unchanged with wind speeds still increasing across
interior waters and as the storm system moves inland, an uptick in
winds to gale force is expected across just about all waters. Winds
are expected to diminish fairly quickly after the system exits
overnight, although there will likely be a quick, but very strong
40-45kt sustained westerly push down the strait where the gale
warning will remain until 12z Saturday. Winds will likely drop to
small craft sometime between 06z-12z in the strait but to avoid
juggling multiple headlines have opted to keep gale thru 12z.

Winds will relax for yet another brief period Saturday very early
morning. The next weather system will be enroute through the day
across the pacific so should see winds begin to increase in the
morning and afternoon. The strait along with northern inland waters
and admiralty inlet should see SCA winds around sunrise, along with
the coastal waters, however, given winds will increase pretty
quickly on Saturday back to near gale force, a gale watch has been
placed offshore. Will need to watch wind speed trends across
interior waters but at the moment, SCA should suffice.

The region will continue to be impacted by a parade of pacific
storms all the way through next week. Headlines of either SCA or
gale will be likely, with the potential for some brief breaks in
between systems. At this time, it is too difficult to be much more
detailed than that.

Kovacik

Hydrology Flooding continues on the skokomish river in mason
county. The river is forecast to recede to below flood stage
Saturday morning.

Extended models continue to show the potential for an atmospheric
river aimed at western washington with the source region for the air
mass from around hawaii in the middle of next week. Snow levels will
be moderately high and rainfall amounts may be high; how high
will depend a lot on how persistent the heavy rain is. There is
the possibility that several rivers around the area could reach
flood stage by the middle of next week. Albrecht jbb
