Update Easterly to northeasterly pressure gradients are
increasing this evening as a deep 970 mb low near 42n 133w moves
northeasterly toward the offshore waters. Over the waters, brief
gales have developed near race rocks bc in the strait of juan de
fuca and fraser outflow is increasing with northeast winds
increasing through haro strait. Gales were hoisted for the eastern
two thirds to the strait and for the northern inland waters.

Gusty easterly winds have developed through snoqualmie pass and
northeasterly winds are increasing through the fraser river valley
ne of bellingham. At this time, the east to northeast winds are
expected to remain just below wind advisory levels. Across the
area, the strongest winds are expected to occur along the coast
and in the north interior as the low passes by to the west, then
peak in the interior south of everett after the low passes by to
the northwest. Updates below are to the aviation and marine
sections with the public forecasts on track. Albrecht

Aviation Southerly flow aloft tonight will continue through
midday Thursday as low at the surface and loft moves northeastward
through the offshore waters. The flow aloft will become
southwesterly as the low pushes NW of the area. At lower levels,
high pressure east of the cascades and lower pressure over the
coastal waters is resulting in easterly pressure gradients. The
easterly flow will become more southeasterly on Thursday and
southerly on Thursday night as the surface low passes NW of the
area. The air mass is dry at lower levels and moist at mid and
high levels. The moisture will increase from the south tonight
through Thursday morning. The air mass is stable.

Low level easterly flow at lower levels is keeping conditionsVFR
despite the gradual increasing in moisture from the south.VFR
conditions are likely to continue through Thursday. As a frontal
system approaches from the south late tonight into Thursday
morning, expect low level wind shear to become an issue at
terminals exposed to low level easterlies. The low level wind
shear will diminish midday Thursday as easterly flow at the low
levels turns southeasterly.

Ksea... Thickening clouds with ceilings dropping to 040-050 after
08z tonight with occasional -ra. Vis expected to remain p6sm.

Expect sfc wind easterly 13-15 kt. Wind at 020 will increase to
sly 20-30kt about 12z tonight giving some llws. Llws will ease
after 20z as low level flow turns more sely. Albrecht

Marine A 970mb low near 42n 133w will lift NE through the
offshore waters and to haida gwaii Thursday night. Northeasterly
pressure gradients are quite strong to the northeast of the low
resulting in gale force winds over the coastal waters. Brief gales
have already occurred at race rocks in the central portions of the
strait of juan de fuca. Gales will spread eastward through the
strait and into the northern inland waters on Thursday. Gale
warnings are now in effect for all of the waters except for
admiralty inlet and puget sound hood canal. Expect wind to
gradually veer to southeasterly then southerly and southwesterly
Thursday and Thursday night as the low passes by to the NW of the
waters.

Another low, this one now near 33n 156w, is forecast to deepen to
around 970 mb as it moves by to the west of the offshore waters,
then to fill as it moves through queen charlotte sound. While this
low will be passing by farther to the northwest, pressure
gradients are expected to be similar or stronger than with the
first system. So, expect another round of gales. Seas over the
coastal waters with the two systems will likely exceed 20 ft at
times, especially away from the immediate coastline. Albrecht

Prev discussion issued 330 pm pst Wed jan 16 2019
synopsis... Active weather will return to western washington
tonight as precipitation associated with an approaching storm system
moves into the area from the southwest. This system will bring more
widespread rain Thursday with increasing southerly winds Thursday
night into early Friday morning. A stronger system will begin to
affect the area again Friday night - bringing another round of
strengthening winds Friday night and heavier, widespread rainfall
through Saturday. Unsettled weather will linger through early next
week.

Short term... A few light showers associated with a weak
upper level system have been working up along the washington coast
this afternoon. This system will weaken as it lifts northward into
the british columbia coastal waters this evening, brushing the
washington coast as it passes. A more organized round of rain
associated with a frontal system will begin to move onto the
southwest washington coast late this evening. This band of
precipitation will work through the area from southwest after
midnight, with the relatively heavier precipitation affecting much
of the interior before daybreak Thursday morning. At low levels,
strengthening easterly pressure gradients will also result in a
period of breezy easterly winds later this evening as the surface
low approaches the coast. Wind speeds are expected to remain below
advisory criteria tonight. Precipitation will pick up again Thursday
afternoon as the front finally moves inland. In addition, advisory
level winds are expected with southwesterlies behind the front
Thursday night for the coast and the interior north of everett. A
wind advisory has been issued for Thursday night through 4 am pst
Friday morning. Winds and showers should ease Friday morning. This
will be a fairly shortlived lull in the action ahead of the next
system expected to begin to affect the area Friday evening.

Long term... Medium range models remain in good agreement on the
second, pacific storm system expected for Friday night and Saturday.

This system is expected to have a deeper tap of moisture and
elevated snow levels, however models continue to show a very
progressive trend with the pattern, keeping the heavier
precipitation to the south over oregon and northern california. This
may help mitigate the potential for widespread heavy rainfall. Warm
frontal precipitation will begin to spread into western washington
Friday evening and lifting fairly quickly into british columbia
Saturday morning. For western washington the heaviest precipitation
continues to be forecast for the southwest slopes of the olympic
mountains, and may well result in potential flooding on the
skokomish river. Beyond this, the most significant impact with this
system will be the stronger southerly winds indicated by the models
for the coast and north interior - possibly reaching wind advisory
levels Friday night. Showers will linger Saturday, especially over
the higher terrain. Could see another quick break in the weather
Sunday with a series of systems affecting the area Monday evening
through Wednesday. Medium range models continue to hint at a pattern
shift for later in the week with a large scale ridge developing over
the eastern pacific, that would drive drier and potentially warmer.

Weather for much of the pacific northwest.

Aviation... Southerly flow aloft will continue today and tonight
with an upper trough offshore. A frontal system will spread rain
into the area from the southwest tonight as the upper trough
approaches. At the surface, easterly offshore flow will continue
with high pressure inland and lower pressure offshore. The air mass
is mostly dry and stable.

There are mainly mid and high clouds today. Moisture will increase
from the southwest tonight as a frontal system arrives. Offshore
flow should keep the low levels relatively dry. Rain will spread
into the area but ceilings are expected to remainVFR, even towards
the coast.

Ksea... Mid and high clouds at times today. Ceilings will gradually
lower tonight as rain develops but they are expected to remainVFR.

Easterly wind 5-10 knots increasing to 10-15 knots tonight and
becoming a bit gusty. Schneider chb
marine... Southerly flow will increase across the region today and
tonight as a low center moves northeast offshore. Gale force winds
are forecast on the coast and at the west entrance, with small craft
advisory winds elsewhere. Another strong system will reach the area
on Friday with seas building to 15 to 18 feet. This system will move
inland Friday night and Saturday, maintaining strong southerly flow
over the waters. A weaker trough may clip the area on Sunday. Chb
hydrology... The light rain coming into the area this afternoon
signals the return to a period of wet weather that will continue
through early next week. The rainfall totals with each passing
system over time is expected to spark a response in river levels.

Given some of the higher rainfall totals expected across the
olympics, the skokomish may reach flood stage towards the end of the
week. Elsewhere, not expecting river flooding over the next 7 days
at this time. Jbb kovacik
