.SYNOPSIS...
Mountain snow and spotty lowland rain showers will taper off
this evening. A trend towards cooler and drier conditions will
emerge over the weekend with areas of morning fog through Monday
before the next weather system arrives by the middle of next
week.
&&
.SHORT TERM /TONIGHT THROUGH SUNDAY NIGHT/...
The latest forecast remains on track with no updates. Light
shower activity continues to become more isolated across the
north interior this evening. Expect this trend to continue as
broad, low amplitude ridging gradually slides east into the area
for the weekend. This will lead to mainly dry conditions
areawide Saturday through at least Monday. The exception may be
across far southwestern Washington where dynamics associated
with a cutoff low moving near the Oregon/California border could
spread some clouds or even stray precipitation across into
those areas. Where we are cloud-free overnight, expect areas of
patchy fog to develop and temperatures to fall into the low to
mid-30s.
&&
.LONG TERM /MONDAY THROUGH FRIDAY/...
As the pattern evolves Tuesday through late next week, the door
will open to fairly typical winter frontal systems. The most
likely scenario is precipitation spreading from west to east
across the area Tuesday into Tuesday night bringing lowland
rain, mountain snow, and some areas with breezy winds. At this
time, the potential for significant weather hazards appears low
and the precipitation looks primarily beneficial for the
region, adding some much needed snow to the snowpack in the
mountains. That said, given a weak favoring of above normal
temperatures, snow levels may limit the overall additions.

.AVIATION...
West to northwest flow aloft will continue into Saturday with a
weak upper ridge centered offshore. Low end VFR ceilings will prevail
for most areas this evening. Ceilings will then deteriorate to
low MVFR or occasional IFR areawide overnight as stratus
continues to expand across western Washington before scattering
out again Saturday afternoon.
KSEA...Low end VFR will lower back to low MVFR or tempo IFR 10Z-20Z
Saturday. Low clouds are expected to scatter out Saturday afternoon.
Surface winds S/SW 7 to 10 knots through this evening...then backing
to N/NE overnight and rising to 9 to 12 knots Saturday afternoon.

.MARINE...
Surface high pressure will build into the waters today with onshore
flow easing. Winds will transition more northerly or weak offshore
over the weekend as a surface ridge settles over the interior of
British Columbia. The next frontal system will move into the
waters Tuesday into Wednesday.
Seas will hover near 10 feet for the outer Coastal Waters through
today, before subsiding back into the 4 to 7 foot range over the
weekend through Tuesday.
