.SYNOPSIS...Periods of wet and windy weather are on tap through
Sunday night as a vigorous weather system affects the region.
Showers will taper off on Monday. Another front will reach the area
around daybreak Tuesday. High pressure will move over the region
Wednesday and Thursday. Weak fronts will reach the area around the
end of the week.

&&

.SHORT TERM...Rain is moving through the area this evening as a warm
front moves north through Western Washington. A deep low will track
to northern Vancouver Island overnight. A vigorous trough or cold
front will move through the area Sunday and wind advisories are in
effect--first for the coast and then followed by areas Everett
north. Another trough arrives Sunday night for more windy weather.
Monday and monday night will be a break before the next front
arrives around daybreak Tuesday. That system looks pretty run of the
mill--deep low pressure tracks through Queen Charlotte sound
Tuesday morning and gradients over Western Washington are pretty
modest, just another rainy blustery November day.

.LONG TERM...By Wednesday, a bit of a lull in the weather pattern. A
mid level ridge over the eastern Pacific will build north and allow
heights to climb to around 565dm by Wednesday evening. There won't
be much increase in temperatures at the surface, however, as the
biggest and most  impact of the higher heights will be in helping to
bring a brief dry spell into the region. It will not be until late
Thursday evening and early Friday morning when the next chance of
rain will return as a weak system slides into the area. This may be
followed by return to a more active pattern at the very end of the
long term period into next weekend. Temperatures will remain near
normal also through the long term portion of the forecast period.

.AVIATION...A warm front will lift north through Western
Washington tonight for rain across the region. The air mass is moist
and stable. The flow aloft is southwesterly. Ceilings are mainly in
VFR range. Expect gusty SE winds to 30 kt along the coast and in the
North Interior. Showers and gusty winds will continue on Sunday as a
cold front moves inland. A flip to onshore flow will bring lower
cloud levels with MVFR ceilings possible in heavier showers. 33

KSEA...Rain across the region tonight with E/SE winds to 10 kt at
the surface. Winds will become more S/SW by 21z Sunday as a cold
front moves in. Gusty winds to 30 kt possible during the afternoon
with showers in the vicinity. 33

&&

.MARINE...A warm front will lift north through Western
Washington tonight with gales over most waters. Strong onshore flow
will follow on Sunday as a cold front moves inland. A trough will
cross the area Sunday night. Another strong frontal system will
arrive Monday night and Tuesday with seas at the Coastal Waters
building to 20 to 25 feet. High pressure will bring lighter winds on
Wednesday. 33

.HYDROLOGY...Minor flooding continues on the White River at the R
street bridge. Rainfall in the Olympics should be sufficient to cause
the Skokomish River to rise again and produce flooding by late Sunday
morning. But otherwise, no river flooding conditions are expected.

Following the recent heavy rains and additional rainfall expected
tonight and Sunday, the risk of landslides remains elevated. Any
of the rain tonight, Sunday or early this coming week could
trigger a landslide or two.
