Synopsis Aside from some morning valley fog and low clouds, expect
pleasant weather Wednesday and Thursday before the next front brings
a few light rain showers to the region on Friday. Cool and dry
weather will likely return over the weekend and continue into early
Short term Tonight through Friday... Water vapor satellite imagery
shows a shortwave trough dropping southeastward across the rocky
mountain states. A broad upper level shortwave ridge is building
across the eastern pacific and models are in good agreement it will
amplify and push over the pacific northwest Wednesday and Thursday.
This will lead to a rather benign weather pattern for the region with
generally plenty of sunshine, cool nights and mild daytime
temperatures away from areas of valley morning fog and low clouds.
Expect breezy northerly winds in the willamette valley and along the
coast each afternoon.
The next storm system to impact the region is currently located south
of the aleutian islands. Models are in good agreement this shortwave
trough will progress eastward across the gulf of alaska before
dropping southeastward into the rocky mountain states and eventually
southward into the great basin. Given this storm system's overland
trajectory prior to its arrival, moisture will be limited, but it
appears the attendant front will likely generate at least a few
showers across the area, particularly across our northern coastal and
cascade zones on Friday. Rainfall amounts will be light. Neuman
Long term Friday night through Tuesday... Models and their
ensembles are in good agreement the shortwave trough currently
observed south of the aleutian islands will drop southeastward into
the rocky mountain states before dropping southward into the great
basin Friday night into Saturday. This will place the region under a
cool, breezy and generally dry northerly flow pattern. Cooler air
will likely spread into the columbia basin over the weekend and early
next week, which should result in east winds increasing towards early
next week. Cooler and drier air filtering into the region should
allow many locations to once again drop near or below freezing at
night once again early next week. Models and their ensembles suggest
the area will be dry through early next week so continued the trend
of keeping pops below mentionable thresholds and certainly well below
Aviation The cold front has moved out of the forecast area and
behind it, high pressure is building. Skies are mostlyVFR with
some isolated spots of MVFR with continued cloud cover in the
southern willamette valley. Those areas should becomeVFR by 00z|
Wednesday but will bounce betweenVFR MVFR until then. With
generally clear skies and northerly light winds, there is a
chance of fog development overnight around 12z Wednesday.
However, this will fully depend on whether or not MVFR stratus
builds in earlier than expected, and hinders the cooling process.
At this time, it looks like fog is most likely going to develop
through the southern willamette valley, along the coast and more
prone areas like khio.
Kpdx and approaches... High pressure will keep conditions mostly
clear through 07z Wednesday. Chance of fog development overnight
starting around 12z Wednesday. Winds will remain northerly
through the period and around 5 to 10 kt up to 5000 ft agl. -rm
Marine The cold front has moved inland and the small craft
advisory remains in effect. Seas are expected to build to 10 to
12 ft through Wednesday early morning with the northern waters
easing Tuesday night. Seas in the central outer waters will then
ease to 4 to 6 ft Wednesday night through Friday afternoon.
Tuesday evening, high pressure begins to build across the waters
and remain through Friday morning. Moderate northerly flow will
encourage winds to increase to 10 to 15 kt with isolated gusts to
25 kt, specifically south of newport. These small craft winds
will dissipate Wednesday afternoon. Offshore flow will occur
Thursday through Friday morning.
The next system will move over the waters Friday evening, ramping
up winds and seas into near small craft range. Seas 12 to 14 ft
are possible in the outer waters, with winds 15 to 20 kt with
localized gusts to 30 kt. At this time, the strongest winds are
expected in the central waters. These conditions will hold
through the weekend. -rm

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.
