Synopsis High pressure aloft will keep the region dry through
the weekend. Sunny skies will be the rule, but weakening offshore
flow will result in more areas of late night and morning fog and
low clouds beginning Thursday morning. The upper ridge will break
down next week with a change to a wet and blustery weather pattern
around the middle of next week.

Short term An upper ridge over the area will flatten today and
tonight as an upper short wave passes to the north. There will be
a resultant decrease in low level offshore flow today with light
onshore flow developing this afternoon or evening. It will be
another warm day today with highs in the mid 60s to mid 70s. Some
record highs will probably be set again today.

The upper ridge will rebound across the area Thursday and Friday
for continued dry and sunny weather. Highs will cool mostly into
the 60s but this is still above normal. Weak onshore flow should
result in some night and morning low clouds and fog but these will
burn off each day for sunshine in the afternoon. Schneider

Long term An upper ridge will keep the weather dry this
weekend. Highs will be a few degrees above normal. The upper
ridge will shift inland early next week with a pattern change to
more typical wetter october weather. Monday looks dry for now with
a weakening frontal system bringing a little rain and locally
breezy conditions on Tuesday. Schneider

Aviation Upper level ridge will remain over the area providing
light flow aloft. Low level offshore flow will slowly weaken
overnight. Some patchy fog remains possible again this morning in
the usual river valley locations. Otherwise, clear skies are
expected.

Ksea... Clear skies. Light northerly winds 5 to 10 knots. 14

Marine Low level offshore flow pattern dissipating today as
high pressure weakens east of the cascades. Light flow tonight
with the low level flow becoming weakly onshore Thursday with
high pressure offshore. Light onshore flow pattern continuing
through the weekend. Felton

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
