.SYNOPSIS...
A weak frontal system will traverse the area tonight into
Sunday, bringing cool and cloudy conditions as well as chances
for showers. Temporary high pressure Monday before another weak
front arrives Tuesday. Dry and warmer weather Wednesday into
next weekend as an upper level ridge centered over the southwest
builds back towards the Pacific Northwest.

&&

.SHORT TERM /TONIGHT THROUGH MONDAY NIGHT/...
Breezy conditions continue over Puget Sound and Northern
Interior this evening and should gradually taper off late
Sunday morning. Mostly cloudy conditions prevail across most of
the area this evening, through much of the Seattle metro and
central Puget Sound remains partly cloudy. Light rain showers
are being reported along the coast and Olympic Peninsula. These
conditions will persist through the rest of the day today as a
frontal system works it was across the area tonight. High
temperatures remain on track to reach the 60s to low 70s across
portions of the interior with the most sunshine. Chances of
showers will continue overnight into Sunday, with the best
chances remaining along the Olympic Peninsula, through also
expanding into the northwest Interior during the day on Sunday
as well. This will help keep temperatures unseasonably cool,
with highs remaining in the low 60s on the coast, with upper 60s
to near 70 across the interior, with the warmest temperatures
across the southeastern portions of the area.

Monday looks to warm back up closer to normal, in the 70s to
near 80 with more sunshine during the day.

&&

.LONG TERM /TUESDAY THROUGH SATURDAY/...
An upper level low will remain sitting off the coast of British
Columbia through the first half of the week, with another
shortwave trough moving over the area on Tuesday. That will
bring us another round of cooler, below-normal temperatures
Tuesday as well as chances for showers and breezy winds.

By Wednesday and through the end of the week, the upper level
high centered over the Four Corners region will begin to expand
and retrograde west towards the Pacific Northwest. Heights will
rise through the end of the week. Troughing off B.C. will get
pushed north, but there are the potential for a few shortwaves
moving through the flow that may keep us cooler than otherwise
possible. Onshore flow in the low levels will also help to keep
conditions temperate with at least clouds in the morning.
Temperatures generally look to remain right around or slightly
below normal through the end of the week.

.AVIATION...
Southwest flow continues aloft with an upper level trough moving
into the Pacific Northwest. Widespread VFR conditions present over W
WA this evening save for along the coast, where MVFR to IFR
conditions are present, even though precip along the coast has
become more scattered. Deeper moisture with a frontal boundary
arrives Sunday with low MVFR or occasional IFR in stratiform
precipitation developing along the coast and interior areas from
around KPAE northward. A period of MVFR ceilings for central/south
sound terminals is also expected Sunday morning before VFR
conditions resume here by mid-afternoon.

KSEA...VFR ceilings are expected to continue into tonight, but
confidence has increased in a period of MVFR ceilings developing 12Z-
20Z Sunday. Surface winds largely remaining S/SW 5 to 8 knots for
the TAF period.

.MARINE...
A stalled front offshore will move inland Sunday into Sunday night.
High pressure will build behind the front Monday. Another front will
move into the area waters Tuesday with high pressure again building
in behind the front Tuesday night and Wednesday.

Small craft advisory winds continue to linger over the coastal
waters this evening, easing below criteria tonight. Diurnal westerly
pushes through the Strait of Juan de Fuca in the evenings in the
middle of next week could produce small craft advisory winds.

27/18

&&

.FIRE WEATHER...
Cooler and cloudier conditions are expected across western
Washington this weekend as a weather system moves across the
area. Showers will remain possible through the weekend, primarily
along the coast, west slopes of the Olympics, and portions of
the Northern Interior as a front moves inland on Sunday. Chances
of wetting rains on Sunday are between 65-75 percent along the
North coast and the west slopes of the Olympics. Another frontal
system will move across the area on Tuesday, helping further
mitigate fire weather concerns through the near term.

Warmer and drier conditions return by late next week. However,
with low level flow remaining onshore, expect good relative
humidity recoveries during the overnight hours and minimum
relative humidities to remain above critical thresholds at this
time.
