Synopsis Seasonable weather through this weekend, with areas of
morning clouds. Warmer weather is expected next week with interior
temperatures likely warming into the upper 80s to lower 90s.

Short term Today through Monday... Satellite imagery shows mostly
clear skies early this morning with stratus forming just offshore of
the south washington coast. Light north to northwest winds should
expand the stratus south along the coast and inland up the lower
columbia river valley this morning, but do not expect the low clouds
to make it to the portland vancouver metro area due to an upper
ridge. Increased sunshine this morning will allow for slightly warmer
temperatures this afternoon than what was observed yesterday
(Thursday).

An upper trough approaching british columbia will flatten the upper
ridge today for a more zonal weather pattern that will persist
through Sunday. A surface low associated with the upper trough to the
north will form a weak surface front that will brush by the south
washington coast and willapa hills on Saturday. This will result in
increased clouds along the coast and extreme SW washington, and
occasional light rain. This weak front and clouds will result in
slight cooling Saturday afternoon. Seasonal weather is expected for
Sunday with clouds returning to the coast and parts of the willamette
valley in the morning and clearing in the afternoon continuing
seasonal temperatures, that will be slightly warmer than Saturday.

The upper ridge begins to amplifies on Monday beginning a warming
trend. ~tj

Long term No changes. Previous discussion follows... Monday night
through Thursday... Stronger ridging builds next week, but confidence
remains low in exactly how hot temperatures will get. Models diverge
by Tuesday regarding the location and strength of thermal troughing,
which will have a significant impact on temperatures. If troughing
builds such that we end up with strong offshore flow, temperatures
next week could be quite hot - at least in the mid 90s for a day or
two. But if offshore flow is limited, temperatures will remain
slightly more moderate, maybe reaching 90 for a couple of days. The
place with the biggest swing based on the flow pattern will be the
coast, which can get just as hot or even hotter than inland areas
with strong offshore flow but otherwise remains quite moderate.

Didn't make a ton of changes to the forecast temperatures in the long
term period due to significant model changes in the last 24 hours and
previously mentioned model discrepancies. Bowen

Aviation MVFR CIGS return to the coast late this afternoon but
more likely tonight. Expect some -ra or -dz from about ktmk
northward on the coast after 11z Saturday. For inland locations,
expectVFR conditions through 18z Saturday.

Kpdx and approaches...VFR. Light winds becoming northwest around 10
kt later this afternoon through evening hours. Mh bowen

Marine High pressure over the waters will weaken this
morning, relaxing the winds over the waters. The high pressure
continues weaken into the weekend as a weak trough moves
through. The high pressure strengthens again early next week for
a return to a more typical summer pattern.

Seas around 6 feet will continue through the weekend, the likely
build a couple of feet as more persistent northerly winds develop
early next week. Mh

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.
