Synopsis for southern washington and northern oregon coast.. Thermal low pressure along the coast will shift over the waters tonight. Northerly winds will veer northeasterly this evening and then easterly by Tuesday. Winds will be especially gusty west of the river gaps in the coast range. Low pressure moving north mid-week will bring a southerly wind reversal, possible gusty winds and fog/low clouds.

Synopsis High pressure over the region will bring lots of
sun and warm temps to much of the region through mid week. Cooling
along the coast begins wed, and spreads inland Thu and fri. An upper
level low approaching the north ca coast late in the week will
spread a chance for showers and maybe even a few thunderstorms to
the reigon late Thu and Thu night. Low pres will stick around
through the weekend keeping chances for showers going along with
seasonably cool temps.

Short term Tonight through Thursday... An upper level ridge seen
in water vapor pictures Mon afternoon along 130w, will move inland
over the pacific NW tonight, then linger through wed. With a thermal
induced trough along the coast, most inland areas will see an
offshore flow that will help to keep skies mostly clear through wed.

Models indicating 850 mb temps continue to warm Tue and wed, reacing
close to 15c by wed, which should be good for highs into the lower
80s inland valleys, and which may also challenge some of our high
temp records. Along the coast onshore flow appears likely to develop
late tue, then again Wed as the surface trough begins to shift
onshore. The turn to onshore flow, earliest along the central or
coast, will cut off the diurnal temp rise along the coast earlier
each day.

By Thu models develop a sse flow over the region as a large upper
level low approaches the north ca coast. As the upper heights begin
to come down and the surface trough moves inland, a developing
onshore flow will begin to bring temps down over the interior as
early as thu, although some areas may not see much cooling thu. The
se flow and some diffluence aloft may begin to destabilize the
atmosphere enough Thu afternoon to introduce a slight chance for
thunderstorms to the lane county cascades.

Long term Thursday night through Monday... While models agree on
the upper low off the north ca and south or coast eventually moving
inland, models diverge some on how quickly that happens, and what
happens afterwards at the end of the weekend. As the low level flow
likely remains onshore through the extended period, the differing
models wind up yielding nearly the same forecast; a chance for
showers each day with temps near seasonal normals.

Aviation Vfr conditions expected tonight and Tuesday.

Offshore flow will continue through early Tuesday before easing
Tuesday afternoon.

Kpdx and approaches...VFR conditions through Tuesday. Fairly
strong easterly wind gusts of 20-30 kt will continue through
18z-20z Tuesday, then ease off.

Marine Surface thermal trough along the coast will drift
offshore tonight. This will result in winds becoming increasingly
offshore with wind gusts of 15 to 20 kts. Some isolated gusts
near 25 kts possible downwind of the coastal river gaps
including the mouth of the columbia river tonight.

A longer period westerly swell arrives later tonight into
Tuesday, but wave heights remain below 10 ft. During the latter
half of the week, a southerly wind reversal may develop along the
coast bringing some fog and low clouds. Seas likely will remain
below 10 ft. Small craft advisory level winds could return
towards the weekend, as a front moves into the north oregon and
south washington waters. Tw

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.
