.SYNOPSIS...
A frontal system will continue to cross the region today,
bringing an additional round of breezy winds, lowland rain, and
mountain snow to western Washington. A low pressure system will
track northward along the coast on Wednesday, bringing in
another round of precipitation and potentially strong winds.
Unsettled conditions will continue into Thursday and beyond as
troughing persists over the western US.

&&

.SHORT TERM /TONIGHT THROUGH WEDNESDAY NIGHT/...
A frontal system will will continue to move across the state
late tonight. Rain will continue across the mountains, but winds
have largely tapered off. Post-frontal showers will continue
into Tuesday morning, especially over the Olympics and Cascades,
with some drying and brief sun breaks for the lowlands by
Tuesday afternoon.

The next incoming weather system will intensity off the coast of
California late Tuesday and shift northward across western
Washington on Wednesday. While forecast models continue to
struggle with the exact track of this surface low feature, it
poses a risk of a low probability, high impact wind event
alongside additional precipitation. East to southeast winds are
likely to pick up during the morning Wednesday along the western
slopes of the Olympics and Cascades, followed by a surge of
stronger southerly winds during the day Wednesday. While
ensemble mean wind gusts continue to range generally between 30
to 40 mph across much of western Washington, a high end scenario
could bring sudden winds reaching 60 mph or more if the low
pressure system tracks in the vicinity of western Washington.
Confidence will increase as more high resolution forecast data
becomes available as the event draws closer. It will remain
extremely important to continue to monitor the evolving forecast
over the next few days, especially given the antecedent soil
moisture which may allow for heightened impacts at slightly
lower wind speeds. In addition to the potential gusty winds on
Wednesday, The lowlands will see up to a quarter inch of rain
while elevations above 2500 feet will see a few more inches of
snow accumulation.

&&

.LONG TERM /THURSDAY THROUGH MONDAY/...
Lighter precipitation is on track to spread into western
Washington on Thursday and Friday as the low pressure system
exits to the north. High pressure is then forecast to build
of the western US coast and build inland towards the Pacific
Northwest, helping to shift the bulk of any incoming
precipitation northward. Conditions may dry out across much of
the lowlands by next weekend, with lowland rain and mountain
showers along the British Columbia border. While unsettled and
cooler conditions will persist, signals for another incoming
atmospheric river system towards the end of next week have
decreased, with models focusing this potential system northward
into Canada.

.AVIATION...
Southwest flow aloft will continue into Tuesday
with a frontal system and associated upper trough moving
through western WA this evening. Gusty southerly surface
winds will accompany the front before easing overnight. Ceilings
will lower to MVFR at times in rain. Precipitation will
diminish overnight with areas of MVFR continuing. A return to
VFR is expected across much of Western Washington on Tuesday
morning.

KSEA...Ceilings will lower to MVFR in rain at times this
evening. MVFR ceilings will remain in place overnight before

.MARINE...
A frontal system will move onshore late this evening. A weak surface
trough will remain over the coastal waters into Tuesday.
Considerable uncertainty remains in the forecast for midweek with
the path and strength of a secondary trough. A broad surface trough
well to the south of the area and high pressure over the interior of
British Columbia will lead to a period of northerly flow late in the
week.

Seas are expected to briefly drop below 10 feet midweek before
building back to double digits again Friday onward.

.HYDROLOGY...
Rivers across western Washington continue to trend downward as
precipitation across the region lightens up. A frontal system
will bring in generally half an inch of rainfall or less through
Tuesday with snow levels near 2000-2500 feet. No significant
rises are expected on area rivers, with the Skokomish River
being the only river to remain in flood stage until Wednesday.

Additional rainfall throughout the week is not expected to cause
any additional rises to area rivers, and flooding outside of the
Skokomish River in Mason County is not expected over the next 7
days.

Additionally, the threat of landslides has decreased across
western Washington.
