Synopsis Highs pressure aloft will bring dry weather tonight
and Sunday. A weak system will bring clouds and a chance of rain
Sunday night and Monday. Higher pressure aloft is expected to
build offshore Tuesday into mid week for a return to sunshine and
warmer temperatures.

Short term An upper ridge will remain just offshore through
Tuesday with northerly flow aloft for western washington and weak
low level onshore flow.

Morning clouds Sunday should give way to partly to mostly sunny
weather in the afternoon. A weather system will move over the top
of the ridge and bring a threat of rain Sunday night and Monday.

Rain will be likely at the coast with lesser chances elsewhere as
the system moves onshore and weakens. Monday looks to be mostly
cloudy all day as the weather system moves onshore.

The upper ridge will rebuild over the area on Tuesday for a dry
day and some sunshine by afternoon. Highs will be near normal
Sunday and then cool a few degrees Monday with additional clouds
and spotty light rain. Highs should bounce back to near normal
again Tuesday. Schneider

Long term A strong upper ridge will be in control Wednesday and
Thursday for dry and warmer weather. Low level flow will become
offshore which should help highs warm well into the 70s - maybe
even lower 80s in some location.

The upper ridge will shift inland and an upper trough will reach
the coast Friday. There might be spotty rain near the coast but
the main impact will be to bring some clouds and a few degrees of
cooling.

Westerly flow aloft will prevail Saturday with low level onshore
flow. Highs should be near normal and no fronts or weather systems
are expected. Schneider

Aviation An upper level ridge will remain over the region thru
tonight for contd nly flow aloft. The low level flow will be weak
onshore. Expect local ifr CIGS MVFR vsbys to dvlp late tonight or
after 0900 utc.

Ksea...VFR; although, CIGS near 1k ft are possible Sunday morning.

Winds will generally be light and variable.

Marine Higher pressure offshore with lower pressure inland
will result in light onshore flow through Sunday. A weak warm
front moving across western canada will cause the flow to become
southerly on Monday. The flow will become light northerly on
Tuesday in response to higher pressure over british columbia with
lower pressure over northern ca.

Sew watches warnings advisories
Wa... None.

Pz... None.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
