Synopsis Light low level flow today will turn weakly offshore
on Sunday. A weakening front will arrive from the south on
Monday. Low level flow will turn back to offshore as the next
system moves inland south of the area in the middle of next week.

Short term today through Monday Isolated showers will linger
today in the wake of a weak front last night. There should be some
sunbreaks today as well. Showers might increase slightly in the
afternoon with daytime heating, especially over the southwest
interior where it will be a bit more unstable. Highs will be a few
degrees above normal today.

Showers will end this evening as the air mass becomes more stable.

Sunday is looking dry with decreasing clouds as weak high pressure
aloft moves over the area and northerly low level offshore flow
develops. A few showers may linger over the cascades however. The
additional sunshine should allow highs to creep up a few degrees.

A negatively tilted front will move up from the southwest on
Monday for an increasing chance of rain during the day. This front
should be a little wetter than the one last night but it still
looks fairly weak overall with negligible impacts. Schneider

Long term Tuesday through Friday Previous
discussion... Extended models in pretty good agreement with some
showers lingering around on Tuesday. Upper level low off the coast
moving south into oregon on Wednesday pulling most of the shower
activity south of the area. Will cut back on the pops and if the
model trends continue look for the forecast for Wednesday to dry
out in the next few forecast packages. Nothing organized headed
toward western washington Thursday and Friday but with a weak
upper level trough over the area will have to keep a chance of
showers in the forecast. Highs will be near to slightly above
normal, in the mid 50s to lower 60s. Lows will mostly be in the
mid 30s to mid 40s. Felton

Aviation A weak upper level trough is over the pac NW today.

Showers will be isolated to scattered and mainly affect the coast
and mountains. The flow aloft is southerly. Ceilings are a mixed
bag this morning but most areas areVFR. Light onshore flow will
develop tonight with possible MVFR conditions. Drier weather is
forecast on Sunday as the flow flips to offshore. 33
ksea...VFR conditions expected today with south winds at the
surface. Winds may turn briefly W NW this evening. MVFR cigs
likely overnight with onshore flow. 33

Marine Weak low level onshore flow today will become
light tonight and offshore on Sunday. Next weakening front
associated with a 1008 mb low over the offshore waters moving
through on Monday. The low level flow will turn back to light
offshore Tuesday and Wednesday.

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.
