The wind will turn more northerly during the latter half of the week as surface high pressure begins to center itself over the northeast pacific.

updated aviation discussion.

Synopsis High pressure over the region will produce an extended
stretch of mild days, cool nights, and clear skies through the
weekend. The high pressure may break down next week for a possible
return to rain.

Short term Today through Friday... Offshore flow continues as
cool, dry air mass east of the cascades squeezes through the mountain
gaps on its way to the pacific ocean. The strongest winds will
continue to generally be confined to the western columbia river
gorge. Wind is the main factor regulating temperatures, resulting in
a wide range both across the area and diurnal range from day to night
in wind-sheltered areas. High temperatures will decrease slightly
over the next few days as the lower level offshore flow weakens and
becomes slightly onshore. Forecasting coastal temperatures and cloud
cover will be a challenge due to the timing of a southerly wind
reversal which will bring stratus and cooler temperatures. Right now
looks like tonight into Wednesday the central coast should see the
wind reversal and possibly Thursday for the remainder of the coast.

Expect at least one day along the immediate coast of clouds, possibly
fog, and much cooler and stagnant temperatures after the wind
reversal. Despite the change in wind direction later this week, there
remains no rain in the short term forecast.

Long term Friday night through Tuesday... The 12z GFS and 12z
ecwmf are in agreement into the extended forecast. The models show
a well established ridge of high pressure over the area. This ridge
will keep us dry and slightly warmer than normal for this time of
year. Temperatures will be in the mid 60s to lower 70s along the
coast, and low to upper 70s inland. A surface low within the
willamette valley looks to develop, which will allow for a weak
offshore surface wind pattern into early Saturday. Expect very calm
winds throughout the remainder of the weekend, as the upper ridge
slowly moves out of the area. Models continue to agree that the next
best chance for precipitation and cooler temperatures starts early
next week, as a series of frontal systems works their way from the
gulf of alaska into our area. 42

Aviation 06z package expectations: p6sm skc across the area.

Only minor concern might be for fog development where winds
become light overnight but dew point depressions remain far too
large for that be a credible threat. Columbia gorge outflow winds
will continue with kttd gusts around 25kt and potential for
downstream llws.

Kpdx and approaches... P6sm skc through 18 06z. With kpdx-kttd
pressure gradients now in positive territory, expect light and
variable or light w-nw surface winds similar to last night.

Columbia gorge outflow will continue aloft with east winds 25 to
30 kt just above the surface, leading to probable llws mainly
affecting 10l r departures. Will carry llws until easterly
surface winds return around 17z. There is a somewhat weaker
effect at higher altitudes on the arrivals. Weagle jbonk

Marine High pressure aloft to persist for the next several
days. Light offshore flow weakens over the next 24 hours with
highly variable wind directions. Winds expected to become more
dominant north to northwest by Wednesday evening. Wind speeds 15
kt or less through the weekend. Models in general agreement
showing a weakening frontal system moving through the waters
around the 23rd for possible small craft advisory speeds.

Fairly shallow seas will gradually build toward a longer period 8
foot 15-18 second swell Wednesday night. Seas gradually subside
thereafter until building to near 10 feet toward a week from now.

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.
