troughing. Conditions will dry starting midweek. Another system
Thursday into Friday for additional precipitation, with active
weather continuing into the weekend.
&&
.SHORT TERM /TONIGHT THROUGH TUESDAY NIGHT/...
The latest forecast remains on track with no updates this
evening. A weak round of showers will move onshore tonight and
into Monday morning, dissipating throughout the day. Light snow
accumulations will continue, with 2 to 4 inches likely at
Stevens and Snoqualmie Passes. High temperatures in the upper
40s and lower 50s.
Showers will taper by Tuesday evening as the pattern splits, and
weak upper level ridging nudges into the area. High temps in the
low 50s.

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
Weak upper level ridging will keep the western Washington
mostly dry on Wednesday, with areas of fog in the morning. The
ridge begins to flatten into Thursday, allowing for more
southwest flow and systems to approach the area. Precipitation
chances increase late Thursday into Friday, with troughing
likely into the weekend with unsettled weather and cooler

.AVIATION...
A mix of VFR to MVFR conditions this evening as low-level
moisture remains a concern over portions of W WA. A weak
incoming frontal system will make for widespread MVFR conditions
overnight with the chance for some scattered showers.
Confidence on these showers remains a little shaky /except for
along the coast/ as latest guidance doesn`t seem to be entirely
convinced either with regards to significant impacts to
terminals. Inherited forecast covers this with VCSH...and this
remains the best way to go at this time. VFR conditions are
expected to return to most terminals by Monday afternoon.
The main impact from the front will be an increase in southerly
surface winds with most locations seeing speeds increase to 6-12 kts
early Monday morning and remain that way for the remainder of the
TAF period.
KSEA...VFR conditions in place this evening and should hang on into
tonight...although an occasional dip to high-end MVFR at times
cannot be ruled out, as it has already occurred a few times this
evening. More confidence in MVFR conditions emerging early Monday
morning around 12-13Z, where precip potential may reach its peak.
Some threat will linger into the afternoon hours, but drying is
expected to kick in by 00Z. As mentioned above, southerly winds
throughout the TAF period with speeds generally ranging 6-12 kts.
The strongest winds are expected throughout Monday morning and
afternoon...then starting to ease after that.

.MARINE...
Winds over area waters will remain generally light this
evening. A weak frontal system will moving across area waters on
Monday will boost winds somewhat, but are expected to remain
well below small craft advisory thresholds. Seas running around
8 to 9 ft are expected to rise slightly to around 10 to 11 ft at
11 to 12 seconds tonight into Monday. Seas then fall Tuesday to
around 5 to 7 ft through Thursday when seas look to rise back
up above 10 ft. A small craft advisory for seas remains in
effect through Monday afternoon. Benign marine conditions return
Tuesday and Wednesday as broad high pressure briefly builds
across the area. The next frontal system will move through the
area Thursday into Friday bringing the potential far another
round of marine headlines and impacts.

.HYDROLOGY...
No river flooding is expected over the next 7 days.
