Synopsis An upper trough will bring showers and a slight chance
of thunderstorms today and this evening. Showers will decrease
Saturday as the trough shifts inland. The pattern will remain fairly
wet into the middle of next week as a series of weather systems move
through the area.

Short term Radar and satellite imagery indicate a front has moved
east of puget sound, leaving a more showery pattern behind. Visible
satellite picture indicates there should be at least some clearing
today, though a cumulus field is likely to fill in the clear areas
and there will be showers as an upper trough remains over the
region. The air mass will be unstable enough for a slight chance of
thunderstorms this afternoon and early evening. Snow has tapered on
the volcanoes and the winter weather advisory in the cascades will
be allowed to expire at 11 am. Snow will continue at times in
showers. Highs today will be mainly in the lower to mid 50s.

Showers will taper tonight and become somewhat confined to the
mountains and coast with the loss of daytime heating. The upper
trough over the area will maintain a chance of showers into Saturday
but the coverage will be less than today. Showers will taper
significantly Saturday night as high pressure aloft briefly moves
over the area. Sunday morning is likely to be dry as well over most
of the region.

Another frontal system will bring an increasing chance of rain
Sunday. This system is somewhat split and not too impressive but all
areas should see some rain. Rain will move onto the coast in the
morning. The interior will likely be dry until afternoon when rain
will arrive. Burke/schneider

Long term Previous discussion... An upper trough will shift east
of the area Monday for decreasing showers but there won't really be
any break in the wet weather as warm front rain from the next
frontal system will already be moving into the area in the
afternoon. The warm front should result in a drippy Monday night. A
trailing cold front will keep rain chances high on Tuesday and
Wednesday. Drier weather is expected on Thursday as an upper ridge
builds over the northeast pacific. Schneider

Aviation An upper trough off the coast is expected to
weaken and move onshore Saturday. SW flow aloft over washington
becoming westerly Saturday. Air mass moist and weakly unstable.

Areas of showers east of the offshore upper trough today into this
evening. MainlyVFR ceilings though dipping to MVFR in some showers.

Sunbreaks between the showers at times as well. The air mass is
unstable enough that any warmer sunshine may help develop an
isolated thunderstorm from about 20z-02z. Afternoon convective
temperatures will run from about 47 to 51 deg. Decreasing showers
after sundown this evening but continuing and more widely scattered
into Saturday morning.

Ksea... PrimarilyVFR ceilings today dipping to the upper end of MVFR
in passing showers. The risk of any afternoon thunderstorms is no
more than 20 percent. SE winds this morning should become S to SW by
18z and pick up this afternoon to 10 to 20 kt before easing after
02z. Buehner

Marine A 992 mb low 350 nm west of CAPE flattery will continue
tracking north into the central british columbia coast today. Weak
higher pres to build over the coastal waters through tonight and
Saturday. Onshore flow into western washington today to weaken
tonight.

The next pacific frontal system is forecast to move onshore late
Sunday. A following frontal system is expected to arrive by Tuesday.

Both of these systems look relatively weak and gale force winds
appear unlikely. Buehner

Hydrology River flooding is unlikely over the next 7 days.

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.
