Synopsis A frontal system will move inland tonight with an
upper trough over the area on Wednesday for some lingering
showers. Dry northerly flow aloft will prevail Wednesday night
and Thursday. A second frontal system will reach the area on
Friday followed by a cool upper trough on Saturday. An upper
trough will linger over the area into early next week.

Short term tonight through Friday A front is currently moving
inland and rain has chance to showers. The mountains will pick up
several more inches of snow tonight before showers taper. Showers
will linger into Wednesday with a broad upper trough over the
area but the trend will be for decreasing activity during the day.

Showers should end Wednesday night with a dry day on Thursday
under cool northerly flow aloft. A second frontal system will drop
down from the northwest on Friday for another round of rain and
mountain snow.

Snow levels will remain low for the next few days with the
lowlands flirting with snow at times but widespread accumulations
are not expected. For tonight and Wednesday morning there could
be spotty light accumulations on higher hills and locations away
from the water closer to the cascades. A puget sound convergence
zone could also bring local accumulations. The Friday system could
also bring a little low elevation snow, especially in the morning
before temperatures warm during the day but low level southerly
winds should be a limiting factor. Schneider

Long term Saturday through Tuesday Previous discussion... The
forecast challenges of the short term continue into the long term
today.

The past 3 runs of the GFS model show upper level troughing
amplifying over the area late Saturday into Sunday. As an upper
low drops just south of seattle, the GFS forms a deformation band
into the central puget sound area Saturday night into Sunday night
and indicates possibly several inches of snow down to near sea
level (the 18z solution is farther north with the band, more into
skagit county). The ECMWF is cold but drier. At this point, it is
anyones guess, but it does appear that cold and unsettled
conditions will keep things interesting through the weekend.

A southern stream system moving into cold air in place over the
region later Monday or Tuesday may make for more interesting
times, though models are having a hard time as the pattern shows
some signs of breaking down.

At this time, the forecast was initialized with the national blend
of models and will be refined as we get closer to the events. But
it does appear that temperatures will remain below normal and
weather will generally be active for the next week or so. Albrecht

Aviation A frontal system will move inland tonight with a broad
upper trough over the area on Wednesday and northerly flow aloft.

At the surface, onshore flow behind the front tonight will turn
more northerly on Wednesday as high pressure builds over southern
british columbia. The air mass is moist and slightly unstable.

Low clouds will be prevalent tonight and Wednesday morning.

Ceilings should improve later Wednesday as the low levels dry
with some areas scattering by Wednesday evening.

A puget sound convergence zone will likely form over central
puget sound tonight, shift south Wednesday morning and then fall
apart. Schneider
ksea... Showers and low clouds tonight. A rain snow mix is possible
later tonight but no accumulations are expected. Showers will end
Wednesday morning and ceilings will lift during the day.

Southerly wind 5-10 knots will switch to northerly Wednesday.

Schneider

Marine A frontal system will move inland tonight. Most waters
will have small craft advisory strength westerly winds behind the
front into Wednesday morning. The central and east entrance strait
of juan de fuca could have marginal gales this evening. There will
also be some 12-15 foot west swell moving into the coastal waters
later tonight and Wednesday.

Winds will turn more northerly on Wednesday as high pressure
builds into southern british columbia and then more easterly
Wednesday night and Thursday as the high pressure shifts
southeast.

A second frontal system will drop down from the northwest on
Friday. Northeasterly offshore flow will develop next weekend as
high pressure builds over the interior of british columbia again.

Schneider

Hydrology River flooding is not expected for the next 7 days.
