Synopsis A weak front will bring a little rain this evening.

Showers will become isolated behind the front tonight and Saturday
then end Saturday evening. Another front will reach the area on
Monday. No organized weather systems are expected for the rest of
next week but weak upper troughs will bring a chance of showers at
times.

Short term tonight through Monday A skinny front will bring
a few hours of light rain late this afternoon early this evening
as it moves from southwest to northeast across the area. It will
get a little breezy with the front for a few hours but nothing
too exciting.

Showers look pretty limited behind the front and most areas will
be dry later tonight into Saturday morning. Some showers should
bubble up later Saturday with daytime heating and a weak upper
trough moving into the area providing some lift. An isolated
thunderstorm is possible in the afternoon near the coast and over
the southwest interior where it will be more unstable but the
chances look to low to mention in the forecast.

Showers will pretty much end after Saturday evening as weak high
pressure aloft moves over the area. Low level flow will turn
offshore on Sunday which should help dry things further with
clouds decreasing during the day. Another front will move into the
area from the southwest on Monday for an increasing chance of
rain. Highs will be near to slightly above normal the next few
days. Schneider

Long term Tuesday through Friday Some showers will linger
into Tuesday behind the Monday front but the trend will be for
drying. It looks like an upper level blocking pattern will
develop Wednesday and probably continue into Thursday and Friday.

This should keep any fronts or organized weather systems out of
the area but it also makes for a rather squirrely pattern with low
confidence in the details. There will likely be some dry periods
mixed with times when there is a chance of showers. Schneider

Aviation A cold front will spread rain inland this evening
across western washington. The flow aloft is southerly. The air
mass will remain moist overnight with onshore flow and additional
showers. MVFR ceilings are likely. Drier conditions are expected
Saturday morning as the flow turns offshore. 33
ksea...VFR conditions this evening. Rain spreading to the
terminal by 22-01z. S winds at the surface increasing to 10-15kt.

MVFR CIGS likely overnight with additional showers. 33

Marine Winds will increase over the waters tonight as a cold
front moves inland - small craft advisories are in effect for all
waters. Meanwhile, seas will also build to 10-14 feet at the
coastal waters and west entrance. Winds and seas will ease on
Saturday. The flow will turn offshore on Sunday. The next frontal
system will arrive on Monday, likely bringing another round of
small craft advisories. 33

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

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
