Area Forecast Discussion
National Weather Service Seattle WA
918 AM PST Fri Jan 29 2021

.UPDATE...A few stubborn showers remain this morning, but still
expecting a dry afternoon most areas. The first of a series of
fronts arrives tonight, but will be rather weak. The ones that
follow Saturday night and again Monday will be more substantial in
terms of precipitation along with some gusty winds for the North
Interior. First thoughts on mountain snow are that advisory amounts
look possible for the higher passes (Stevens, etc) and probable for
places like Mt Baker and Paradise. Models and ensembles still
leaning toward a shift in pattern by mid next week which favors a
more north/northwest trajectory with weather systems that reach us.
More on that later. Aviation and marine discussions updated below. 27

&&

.SYNOPSIS...A front will approach the area later today and move
through tonight. Another system over the weekend for additional
lowland rain, mountain snow, and locally breezy winds. Drier
weather late Tuesday into Wednesday as a ridge builds offshore.

&&

.SHORT TERM /TODAY THROUGH SUNDAY/...Mostly cloudy skies for most
of the area this morning with patchy fog across the southern Puget
Sound area. Mainly dry weather today as the next front approaches
later, though some drizzle is possible morning. Showers will move
onshore into this evening and slide east tonight as the weak
front moves through. Lowland rain and light mountain snow through
Saturday morning. Breezy winds with the front, especially across
northern areas including the San Juan Islands, western
Whatcom/Skagit County, and Admiralty Inlet tonight into Saturday
morning with a few gusts of 30-40 MPH possible. Temperatures in
the mid to upper 40s through Saturday.

An upper trough will be offshore through Sunday for additional
lowland rain and mountain snow at times into early next week.
Precipitation for the lowlands will not be steady through the
weekend but rather times of showers for the area. The heaviest
mountain snow will be focused on the Olympics and North Cascades
through the weekend. Amounts of 4-6" possible for Snoqualmie Pass
through Sunday with a transition to rain possible Sunday afternoon
as snow levels increase to near 3500 feet. 6-8" for Stevens Pass
through the weekend. Temperatures in the upper 40s for Sunday.

.LONG TERM /MONDAY THROUGH THURSDAY/...The upper trough will
slowly slide east Monday and Tuesday for additional light lowland
rain and mountain snow. Precipitation may linger into Tuesday
night before drier weather for Wednesday as a ridge builds
offshore. Ensembles are consistent in a system sliding along the
ridge and moving through Western Washington late Thursday of next
week. Possibly a brief period of heavier mountain snow with this
system as well as lowland rain and breezy winds. Below average
temperatures may begin later next week depending on the position
of the ridge offshore as most guidance suggests troughing east of
the area. This will need to be monitored as we go through next
week. Temperatures from Monday through Thursday in the mid to
upper 40s. JD

&&

.AVIATION...Continued southerly flow aloft will persist across
the region through this afternoon with a moist air mass in place.
Current radar still showing some light showers around portions of
the Sound this morning lifting northward and satellite indicates
areas of fog across the central and southern Sound, Southwest
Interior, and along the Pacific Coast. Overall, this continues to
result in a mixed bag of flight conditions across the region this
morning, with many terminals reporting IFR to LIFR conditions
along the central and southern Sound. Overall, expect conditions
to start improving by late morning/early afternoon for IFR/LIFR
terminals as southerly winds and daytime mixing helps to lift
ceilings. However mid-level clouds will begin to arrive and
thicken later in the day ahead of an approaching front. This front
will bring a round of breezy southerly winds to most terminals
tonight along with steady rain and lowering ceilings.

KSEA...MVFR conditions near the terminal, however could still see
ceilings bounce around with some fog remaining in the vicinity of
the terminal. Expect overall improvement to VFR by late morning/early
afternoon. S/SE surface winds 4-8 kts, increasing to 8-12 kts
tonight. Lowering ceilings expected after 06z Sat with the approach
of the next frontal system. Cullen/Borth

&&

.MARINE...Increasing southerly flow across the coastal waters this
morning ahead of the next frontal system. Expect to see advisory
winds begin over the coastal waters by early afternoon. Maintained
the gale watch for tonight for the coastal waters and also east
entrance Strait and northern inland waters zones, as guidance
continues to indicate the potential of gales developing after
sunset through early morning. Another front arrives late Saturday
into Sunday for another round of at least advisory strength winds
across most of the waters. Cullen/Borth

&&

.HYDROLOGY...A series of fronts and associated trough will bring
some reasonably healthy QPF amounts in the Saturday/Monday
timeframe. This will cause some rises on area rivers, but, at this
time, it appears that the QPF and snow levels will remain low
enough to preclude any widespread flood concerns. Current guidance
puts the Skokomish River just short of minor flood stage by late
Sunday evening. The situation will be monitored.
