Synopsis Showers diminish tonight as a ridge of high pres builds
overhead. The ridge brings dry weather for most of the region
Saturday through early Sunday morning. A cold front crosses mainly
Sunday mid-day through mid-day Monday. Expect gusty winds, moderate
rain, and moderate cascade snow, mainly above the passes. Next week
looks to be wet overall with rainy weather affecting at least the
first part of holiday weekend travel. Snow levels during this time
appear to remain rather high with limited impacts across the
cascade and coast range passes.

Short term Tonight through Monday... Showers are beginning to
taper off today from south to north as a short period of high
pressure builds north for the next 48 hours, or so.

Showers should completely dissipate tonight leaving the entire cwa
will dry tomorrow with the far northwest corner of the area being
the last to dry out around daybreak. The clearing skies both tonight
and for many areas Sunday will result in patchy to areas of fog
developing in the valleys.

On Sunday the progressive pattern continues with a quasi-short wave
trough dropping south from the gulf of alaska. The digging trough
will tap into a longer fetch of moisture stretching south toward
hawaii. This brings a warm and moist air mass in ahead of the cold
front Sunday afternoon through early Monday. Fortunately, the trough
and associated front do keep enough southerly motion such that a
threat of numerous hours of rain or snow will be limited. Snow
levels will change from 6-7,000 feet when the bulk of the precip
occurs, to about 3-5,000 feet with and behind the front when the
moisture stream is greatly diminished. The front will have largely
exited the area by Monday afternoon, but may hang on to the lane
cascades until the very late afternoon. Additionally, winds ahead
of the front will be breezy for many willamette valley areas and
windy at the coast. Strongest gusts at the coast appear to be 45-50

Long term Monday night through Friday. Overall confidence has
improved in the forecast for next week today with better model
agreement. Weak shortwave ridging may provide a very brief dry
period later Monday, but the next frontal system will then quickly
approach by Tuesday. This disturbance will bring another round of
steadier rain across the region Tuesday and Wednesday, so expect wet
conditions for any pre-holiday travel. For the thanksgiving holiday,
some chance of rain will continue across the area, but expect
temperatures to be several degrees above seasonal normals, with
afternoon highs in the mid 50s, with perhaps upper 50s at a few
spots. However, snow levels look to remain well above the cascade
passes during the time. Another short-lived break from the rain is
likely on Friday, but the next system quickly arrives by next
weekend. Cullen

Aviation Showery weather continues through this afternoon.

Flight conditions will be mostlyVFR with occasional MVFR cigs
with the heavier showers. The showers will be mainly confined to
the south wa and north or coast and the cascades this evening and
tonight. Patchy fog and or low stratus is possible for the
interior valleys late tonight into Saturday morning. Keug and
kcvo are the most likely airports to see fog since they have a
better chance for clearing skies late tonight.

Kpdx and approaches... Showers will continue through this
afternoon with mostlyVFR conditions. There will be occasional
MVFR ceilings with the heavier showers, but the chance for this
decreases throughout the day. Showers should end this evening.


Marine Seas have improved this afternoon as heights continue
to drop and periods have increased slightly. Conditions will
continue to improve into Saturday as high pressure builds.

However, winds become southerly Saturday as the next front
approaches then increase significantly starting Saturday evening
and Saturday night. Hoisted a gale watch starting Saturday
evening, but highest winds will be Sunday. There remains some
potential for storm-force gusts Sunday, but not confident enough
for a storm watch. In addition to very strong winds, seas will
likely approach 20 ft Sunday. A low moving along the front will
slow its progress and the strong winds and seas may remain across
the waters south of cascade head through Monday morning. Another
front is expected Tuesday with another chance for gales.

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 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.
