Area Forecast Discussion
National Weather Service Seattle WA
252 PM PDT Tue Sep 28 2021

.SYNOPSIS...Showers remain active across the area this afternoon.
The chance of thunderstorms remains through the rest of the day. A
frontal system will begin to make its way through the area
Wednesday. This system will bring breezy conditions followed by
widespread rain. Once the system moves through weather will be
fairly quiet for the weekend and for the early part of next week.

&&

.SHORT TERM /TONIGHT THROUGH FRIDAY/...Showers persist throughout
the region today as onshore flow persists. Moderate to heavy rain
is expected to occur beneath some of these showers. Areas beneath
the Puget Sound Convergence Zone are more likely to see more
persistent rain showers and possibly some thunderstorms. The PSCZ
is not expected to remain mostly stationary over the Everett (and
eastward) area. A frontal system will begin to make its way
towards the area Wednesday. As this system approaches winds will
begin to pick up starting at the coast in the morning and
progressing inland throughout the day. As is usually the case
areas directly along the coast and the San Juans and Western
Whatcom county are expected to experience the highest winds. With
SE winds being somewhat channeled through the Salish Sea winds
at the San Juans and W. Whatcom are expected to reach Advisory
level. Rain is not expected to move into the area until late
Wednesday/early Thursday. Rain will gradually taper off late
Thursday with mostly dry conditions and clearing conditions
expected for Friday.

Butwin

.LONG TERM /SATURDAY THROUGH TUESDAY/...A dry weekend is expected
as an area of high pressure moves into the area. There is a
chance of some increased cloudiness starting Saturday as a
shortwave disturbance moves through British Colombia. We will
begin to enter a bit of an unsettled weather pattern at the start
of the work week, with ensembles showing signs of some weak
disturbances moving through the area. Mostly dry conditions are
expected at this time.

Butwin

&&

.AVIATION...Westerly flow aloft continues with a moist and
somewhat unstable air mass in place over Western Washington. Areas
of MVFR in scattered shower activity will gradually decrease and the
air mass will stabilize this evening. Mostly VFR conditions expected
overnight as the next in a series of frontal systems approaches the
region. MVFR ceilings in rain will spread onto the coast by mid
morning with ceilings deteriorating across the interior of Western
Washington Wednesday afternoon as rain develops.

KSEA...VFR ceilings with scattered showers decreasing this evening.
Ceilings deteriorate again Wednesday afternoon as rain increases
with the next frontal system. A developing convergence zone this
afternoon and evening is expected to remain well north of the
terminal. Breezy S/SW surface winds will ease this evening and
become southeasterly on Wednesday morning. 27

&&

.MARINE...A warm front will lift northward across the coastal
waters overnight tonight. A trailing cold front associated with a
sub 980 millibar surface moving toward Haida Gwaii will sweep across
the waters late Wednesday night into Thursday morning. This frontal
system is expected to generate gales across the coastal waters, the
northern inland waters, and the east entrance to the strait with
small craft advisory winds expected all other waters. Winds will
ease across the waters by later Thursday as surface ridging rebuilds
across the area in the wake of the front. Quieter conditions are
expected Friday into the weekend as a ridge over the coastal waters
gradually progresses inland.

A mix of wind wave and swell will keep coastal seas near or above 10
feet into Friday before subsiding this weekend.   27
