Area Forecast Discussion
National Weather Service Seattle WA
930 AM PST Wed Jan 16 2019

.SYNOPSIS...Wet and active weather will return to part of the area
today, with more widespread precipitation affecting the area
interior this evening into Friday. Precipitation will initially be
light to moderate, with a wetter, windier system expected to impact
the region Friday night into Saturday. Unsettled weather will
continue through the middle of next week, before a drier pattern
ensues.

&&

.SHORT TERM...A weak system brushing the area today, bringing
light showers to the coast and southern interior. QFP values will
remain light, with little or no impact with this first wave.

A closed low approaching the Pacific Northwest will bring more
widespread rain into the area from the southwest late tonight.
Easterly low level pressure gradients may tighten up as the surface
low approaches the coast, resulting in some gusty easterlies
Thursday morning. Wind speeds will likely remain below advisory
criteria at least initially. Rain will linger through Thursday night
as a frontal boundary move inland. Winds will become southwesterly
behind the front late Thursday night into early Friday morning. This
will likely be the breeziest period with some potential for advisory
level winds.

.LONG TERM...from previous discussion...Rain looks to taper to
showers briefly Friday afternoon as a weak short wave ridge passes
overhead ahead of the next rain maker. Still seeing evidence of a
notable atmospheric river associated with this system which looks to
pull another round of moderate to locally heavier rainfall across
much of the CWA even as the parent low lifts northeast to the
central BC coast. Luckily given the large displacement of the parent
low and the atmospheric river by Saturday afternoon, much of the
rain will scour out of the area. Could see another quick break in
the widespread rain thru early Sunday but given a look upstream,
another shortwave will approaching the coast. Another round of rain
appears likely at this point.

After Sunday's system, a broader ridge tries to build in. At this
point in time, the ridge appears dirty, with moisture riding over
top of it and perhaps allowing for intermittent periods of rain
thru mid week. Thereafter, a major pattern change is still
forecast to occur, one in which a high amplitude trough will
build across the eastern US, and a high amplitude ridge will set
up along the West Coast. If you're a cold weather lover, you
might want to head east, otherwise, western Washington will
provide for a period of rain-free weather thru the end of the
week.

.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 remain VFR, 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 remain VFR.
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...A return to a period of wet weather will begin today
and continue through early next week. The accumulation of rainfall
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 by this
weekend. Elsewhere, not expecting river flooding over the next 7
days at this time.
