Synopsis The region will continue in an active weather pattern
through the coming week with onshore flow keeping a chance for
showers through most of the week. A cold front will bring strong
winds to the coast and enhance snowfall over the cascades Sunday.

Another frontal system arrives with rain and mountain snow Tuesday,
followed by another cold front Wednesday.

Short term Tonight through Tuesday... Radar and surface
observations showed some scattered showers continuing early sat
afternoon. As a weak ridge of high pres moves across and flow backs
more to the ssw, expect showers to continue to decrease through at
least this evening.

Another trough of low pres aloft swings SE out of the gulf of alaska
late tonight and sun, pushing a cold front onto the coast around
midday sun. The cold front appears to be stretching some as it
approaches the coast with weakening surface pressure gradients, but
low level wind fields in both NAM and GFS both suggest strong enough
winds to justify the potential for a low- end high wind warning for
the coast Sun morning through midday. Will however need to extend
the high wind warning a few more hours past noon, as models have
slowed landfall of the front a few hours, arriving after 18z. As the
cold front moves inland sun, it is followed in short order by a
vigorous short wave swinging across wa early Sun evening. This
should bring an enhanced period of snow to the cascades sun, ESP for
the south wa cascades where orographic lift will be most favored.

Model soundings show some deeper instability along the north part of
the coast Sun night in response to the upper trough swinging
across, so will carry a slight chance for thunderstorms overnight.

Showers will slowly decrease behind the front Sun night throgh mon
night as flow again backs to the south in response to the next
system upstream approaching. A warm front lifts up from the SW tue,
bringing another chance for rain.

Long term Tuesday night through Saturday... Active weather to
continue through the extended forecast period with little-to-no
break in the precipitation. A slow-moving upper-level trough will
keep moisture pushing into the pacific northwest, with low pressure
systems generally riding along a track from the southwest up into
northern washington or british columbia. With this pattern, expect
coast valley rain and mountain snow. Snow levels could fall down to
around 1500 ft behind the front moving through Wednesday night and
Thursday, but still wouldn't anticipate any significant snow below
2000 ft as showers will be dwindling. Saturday, there appears to be
another mild and wet system moving in, bringing snow levels back up
for the weekend. -mccoy

Aviation Despite earlierVFR, MVFR ceilings have increased
inland with ceilings between 1500 and 2500 feet at most inland
locations. However, even locations which are MVFR have
observations of scattered cloud cover between 1500 and 2500 ft.

Visibilities have remained mostly p6sm even with passing showers.

Expect inland ceilings this afternoon and evening to remain
mostly MVFR with occasionalVFR conditions, in contrast to
yesterday when ceilings were primarilyVFR with occasional MVFR.

Jumping ahead to the winds tomorrow morning, have added mention
of gusty winds starting this afternoon at newport and elsewhere
by early Sunday morning. Expect peak gusts between 12z and 18z.

Pdx and approaches... A bit lower ceilings than expected this morning
with mostly MVFR conditions and occasionalVFR conditions.

Southerly winds will increase Sunday morning and gusts may
approach 30 knots shortly after sunrise. Bentley

Marine Winds have started to increase with 31 knot gusts
reported at buoy 89 as of 2 pm and 27 knots at buoy 29. These
winds will continue to increase to gale strength this evening and
quickly to storm force overnight. Therefore, for simplicity, did
not add a short duration gale warning as winds are ramping up.

Front seems to be moving through a few hours later, so have
pushed the timing of the strongest winds back around 3 hours.

Otherwise, no significant changes to the wind forecast.

While winds are ramping up, seas have dropped to the 12 to 13
foot range. Seas will remain here through the evening before
starting to ramp up after midnight. Still expect seas to peak
around 22 to 23 feet near mid-day tomorrow. Seas will be slow to
fall with seas remaining above 15 feet through Monday morning.

Active weather remains through next week with fronts coming
through every 48 hours or so. There is still some uncertainty on
the timing and strength of these fronts, but each of them brings
the possibility of gale force winds and seas approaching 20 feet.

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.
