Synopsis Warm and dry weather for the weekend into early next
week. A weak weather system will bring cooler temperatures later
Tuesday into Wednesday before high pressure returns for the end of
next week.

Short term tonight through Monday Departing shortwave will
bring an end to shower activity across the area as ridge centered
over the 4 corners builds into the region for the weekend. This
will result in a warming and drying trend for Saturday and
Sunday. Weak gradients should result in less morning cloud
coverage with mostly sunny skies across the area each day. Highs
on Saturday will be some 5 to 10 degrees warmer than today with
several more degrees of warming for Sunday. This means
temperatures in the 70s and 80s. Ridge axis begins to shift east
on Monday as trough well offshore begins to move toward the coast.

This will result in slight cooling and perhaps some high clouds.

Ceo

Long term Tuesday through Friday Trough continues to shift
east toward the coast on Tuesday and then moves onshore Wednesday.

Models and their ensembles continue to advertise less than
impressive moisture associated with the system. It's possible we
may see a few showers but chances look low enough to leave the
forecast dry for now with just some increased cloud coverage.

Regardless, will see additional cooling as onshore flow increases.

Flow becomes more zonal for the end of next week as high pressure
attempts to rebuild across the area. Still some disagreement
between model solutions on the degree to which this occurs but
likely will see a slight warm up again. Ceo

Aviation Northwest flow aloft will become light. Low level
onshore flow diminishing. The afternoon cumulus will clear this
evening. Saturday morning will see a few areas of low clouds and
patchy fog burn off quickly with sunny skies for the weekend.

Ksea... Mostly clear with a northerly breeze through Saturday.

Marine Onshore flow will gradually weaken except for the
late afternoon and evening westerlies in the strait of juan de fuca.

The winds over the weekend and into early next week will be typical
warm summer diurnal northerly breezes that peak in the afternoon or
evening.

Hydrology The daily hydrology discussion has ended until the
start of the next rainy season; it will only be updated as needed
until then.

Sew watches warnings advisories
Wa... None.

Pz... Small craft advisory until 5 am pdt Saturday for central u.S.

Waters strait of juan de fuca-east entrance u.S. Waters

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.
