Synopsis An upper level ridge of high pressure will bring clouds
and cool temperatures to the coast and warmer and drier weather
inland. Thunderstorm chances develop Monday over the cascades but
continue Tuesday and expand westward to the valley as well.

Temperatures trend gradually cooler with rain chances during the
second half of the week as a disturbance tracks across the pacific
northwest.

Short term Tonight through Tuesday... Not much in way of changes.

Warm night inland, where afternoon temperatures reached upper 80s and
low 90s. In contrast, coastal beaches stayed in the lower 60s, with
some spots stuck in the middle to upper 50s thanks to persistent low
clouds. Low clouds now working up the river valleys from the coast
into the coastal mountains, with a few spots reporting drizzle this
evening. Gradients suggest that areas of low clouds will filter into
the south willamette valley late tonight into early Sun am. Also, low
stratus will seep up the columbia river to kelso, but likely stalling
their inland progress around kalama.

Otherwise, not big changes in the forecasts and trends through mon.

Water vapor satellite imagery reveals a shortwave ridge over the
northeast pacific. The ridge axis will slowly shift inland through
Monday, which will produce little change in the overall weather
pattern except for gradually cooling temperatures and an increase in
marine clouds pushing inland each morning. Steeper mid level lapse
rates moving into the region will open the door to the possibility of
some showers and thunderstorms developing near the cascade crest late
Monday afternoon and evening. A slight southeasterly component to the
steering flow could allow a few showers to drift towards the
willamette valley Monday evening, but confidence in this scenario is
low at this point.

As we move forward in time, the next shortwave trough is forecasted
to impact the region on Tuesday. Operational model guidance continues
to waver on rain chances for Tuesday with the latest ec coming in
quite dry. Given the basic pattern and a number of ensemble members
continue to show a pattern favorable for at least some shower and
thunderstorm development, will maintain chance to low end likely pops
for Tuesday afternoon and evening. Neuman

Long term Tuesday night through Saturday... A cooler onshore flow
pattern looks to take hold during the second half of the week. Cooled
temperatures closer to model consensus for much of this period as a
result. Rain chances continue to vary wildly among different models
so left a fairly generic rain forecast at this point. However, pops
were increased most periods, particularly during the afternoon and
evening hours when daytime heating may trigger at least some showers
across the area, especially if the upper level trough lingers over
the region. Neuman

Aviation Onshore flow will push the shallow marine stratus
into the western valleys of the coast tonight and persist through
much of Sunday with ifr lifr conditions. Inland areas mainlyVFR
but ifr to low MVFR CIGS expected to seep into part of the south
willamette valley, and along the lower columbia river to near
kspb by early Sun morning. Clouds inland will dissipate by
midday.

Kpdx and approaches...VFR through Sunday. Western approaches may
see patchy ifr CIGS between 11z and 19z Sunday. Mh

Marine Winds will continue below 20 kt through at least the
middle of next week. Northerly winds continue over most of the
waters through the weekend. However nearshore winds will switch
back to out of the south again tonight, accompanied again by low
stratus and fog.

Seas have settled in the 6 to 7 foot range and will settle to
around 5 ft through most of next week. Decided not to issue a
small craft advisory for rough columbia river bar for Sunday's
morning ebb given the relatively benign reports from the morning
ebb today and similar conditions expected tomorrow. Bentley

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.
