Synopsis It will be mainly dry with slightly above normal
temperatures this week. A few showers or thunderstorms are
possible most afternoons and evenings over the cascades.

Short term tonight through Wednesday Broad trough continues to
dig southward into the desert southwest with northeast flow aloft
over western washington. Rebounding heights and partial sunshine
allowed temperatures to jump 15 degrees over yesterday's in many
places. Some instability brought some shower and thunderstorm
activity to the cascades from about pierce county southward. This
will be dissipating as the Sun GOES down. Heights rebound further on
memorial day with low level flow only weakly onshore through mid-
afternoon. This will further boost temperatures with some spots
south of seattle edging close to the 80 degree mark.

Lingering instability over the mountains will bring another round of
possible showers and thunderstorms in the afternoon and evening
hours. Flow aloft will be weak northeasterly. Some activity could
drift into the foothills, but most will remain over the higher
terrain. A decent onshore push will initiate Monday evening. This
will cool high temperatures by 5 degrees or so over the interior and
bring some morning low clouds inland. Otherwise, Tuesday looks like
a dry and very pleasant late spring day. Wednesday will cool a
little further with a repeat of morning clouds and afternoon sun. 27

Long term Thursday through Sunday From previous
discussion... This will be a period of quiet weather with mostly dry
conditions and temperatures near to slightly above normal. A weak
upper ridge on Thursday will gradually be replaced by a mainly dry
upper trough for the weekend. The result will be some minor cooling
and a slight increase in shower chances by next weekend. Schneider

Aviation Easterly flow aloft will continue with an upper level
ridge building into northern portions of british columbia. Surface
flow will be light northerly into this evening becoming onshore
early Monday morning.

Vfr CIGS across W wa will continue through early tonight with a mix
of mid and high clouds. Ifr stratus likely late tonight into Monday
morning along the coast with light onshore flow. Some low stratus is
possible across the sound, especially along the sound sound early
Monday morning. Winds generally light through tonight from 3-8
knots.

Ksea...VFR continue into tonight. Mid and level clouds will be
around through this evening. Ifr stratus possible Monday morning,
though may stay to the south. Northerly winds 5 to 10 knots will
become light this evening. Jd

Marine Light northerly flow through this evening will transition
to onshore late tonight into early Monday. Onshore flow will
continue through Wednesday. A surface low will push into the
offshore waters late Tuesday and dissipate into Wednesday.

Gale watch issued for the central and eastern portions of the strait
of juan de fuca for Monday evening into Monday night with a strong
onshore push. Gale force winds will also be possible Tuesday evening
with another strong onshore push through the strait of juan de fuca.

later Monday and Tuesday. Jd

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.
