.SYNOPSIS...
A broad upper level trough will continue to produce unsettled
and cool conditions across Western Washington into midweek along
with chances for mainly mountain showers. Drier conditions and
a modest warming trend are expected for the upcoming holiday
weekend as a weak ridge begins to build offshore.

&&

.SHORT TERM /TONIGHT THROUGH WEDNESDAY NIGHT/...
The overall weather pattern looks to remain consistent through
the short term period with broad upper level troughing over much
of the western U.S. Cool and cloudy conditions will prevail with
high temperatures remaining below normal, in the mid to upper
60s. Low temperatures will remain around normal, in the upper
40s to mid 50s. Clouds will attempt to give way to some sun
breaks, but mostly cloudy conditions will prevail through the
vast majority of the day. Slight chances for isolated showers
or drizzle from the marine stratus will persist over the
mountains, but meaningful precipitation accumulation is not
forecast.

&&

.LONG TERM /THURSDAY THROUGH MONDAY/...
A shortwave impulse looks to move over the area on Thursday,
bringing a weak frontal system that will traverse the area.
Models are keeping this system mostly dry, with the exception of
some light precip over the northwest portions of the Olympic
Peninsula. Otherwise, cloud conditions will continue for
Thursday. Friday and into the holiday weekend, the model spread
gets larger, but are hinting at weak ridging developing
offshore. This should help to bring more sun back into the
forecast, as well as warming temps closer to normal, up into the
mid to upper 70s.

.AVIATION...
Broad upper troughing over the interior West will maintain
northwesterly flow aloft over Western Washington. MVFR cigs
under stratus is very slowly beginning to break this afternoon.
At this point, will likely just be a brief period of higher-end
MVFR to low-end VFR cigs before clouds fill in and lower once
again overnight. Localized IFR conditions will be possible early
tomorrow morning. The pattern will repeat itself again with cigs
gently raising and breaking up late morning into the afternoon.
Southwest winds 5-10 kt will continue overnight into tomorrow.

KSEA...MVFR cigs with stratus beginning to break up. Will likely
only be a brief period this evening with low-end VFR before
stratus fills back in and lowers to MVFR. Periods of IFR cannot
be ruled out, particularly between 14-17Z Tue. The pattern
repeats tomorrow with a slow lift of cigs with some breaks in
the afternoon. Southwest winds 5-10 kt will continue overnight
into tomorrow.

.MARINE...
Broad high pressure centered well offshore and lower pressure
across the interior will remain the dominant weather pattern
through Wednesday. This will maintain onshore flow with gusty
northwesterlies and steep seas up to for the coastal waters,
especially through the outermost waters where seas may reach up
to 11-13 ft. Diurnally driven westerly pushes will occur in the
Strait of Juan de Fuca as well for Small Craft Advisory winds
each afternoon and evening through the next seven days.

High pressure looks to weaken during the later half of the week
as a broad surface low approaches the central British Columbia
coast and may bring a weak frontal system through the coastal
waters on Thursday. This will weaken onshore flow allowing
winds over the coastal waters to ease and seas subside.

.FIRE WEATHER...
Little in the way of fire weather concerns remain in the
picture into the week ahead as upper level troughing maintaining
cool conditions, high RH, and periodic chances for shower
activity. A trend toward more drier and more seasonable
temperatures is indicated toward late week, but a significant
warm and dry spell is not expected in the next 7 days.
