Synopsis Reminder that it is still winter, with shot of colder air
for this week. Will see heavy snow in the mountains tonight and
Sunday, with snow at times down to the lower elevations of the
region. Dry weather on Mon and tue, then will bring back a minor
threat of precipitation for the region. But, not strong threat, as
overall will stay on cool and drier side for the coming week.

Short term Tonight through Monday... Vigorous upper level trough
now digging into the pac nw. Cold front has pushed inland today, with
breezy southwesterly winds and somewhat mild conditions at the
moment, with temperatures in the lower to middle 50s inland. Decent
onshore flow, with winds gusting 25 to 35 mph across the lowlands,
and 35 to 50 mph over the higher terrain of the cascades. Said winds
will ease a bit this evening, but will stay breezy over the higher
terrain through Sun afternoon.

Much colder air aloft will push inland tonight and sun, allowing snow
levels to tumble down to around 500 to 1000 feet by Sun am. Plenty
of showers to push across region tonight, and with snow levels
lowering, think will have good chance of getting some sticking snow
down as low as 500 to 800 feet later tonight into early Sun am,
mainly in the coast range to portland and northward.

Next upper disturbance now about 100 miles off the north tip of
vancouver island. Models insist this low will push inland over south
washington or northwest oregon later Sun am, then across to north
oregon cascades in the afternoon. Thicknesses and temperature profile
support snow fairly low to east of this low, but not sure if will get
all way to valley floors. Will be close, so will keep snow levels at
400 to 600 feet for cowlitz lowlands southward through
portland vancouver metro, and 700 to 1000 feet south of portland down
to salem and eugene. At moment, leaning to 1 to 3 inches of snow for
areas above those levels, with an inch or less below. But, for most
areas below a 500 to 800 feet levels, snowfall will be spotty or
hit-n-miss as will depend on where showers develop move, with brief
accumulations that will likely melt off a bit after it accumulates on

As the day progresses, air mass will cool further, with snow levels
gradually lowering to valley floors by evening. Suspect this may be
best time for lowland accumulations, but likely an inch or possibly 2
incs for those areas, but may be in question as precipitation will be
gradually decreasing.

Snow will still be falling over the higher terrain, with another 10
to 20 inches of snow in the cascades. Travel over the cascades will
be difficult and slow at times, due to combination of heavy snow at
times along with low visibilities from blowing drifting of snow.

Have also issued various winter weather advisories for snow for many
areas. Also, will maintain winter storm warnings for the cascades
where will see another 10 to 24 inches of snow through Sun night.

Cold front will gradually push south across the region Sun night,
with precipitation decreasing. But, will see much colder air push
into the region, with temperatures dropping into 20s. Any moisture
on roadways will likely freeze, with widespread icy spots a good bet
throughout the region Sun night into Mon am.

Still cold on mon, with highs generally in the 30s for the lowlands,
and 20s in the cascades. flanders

Long term Tuesday night through Saturday... Expect the cold
pattern to continue through the middle portion of next week before
some slight moderation in temperatures later in the week. Forecast
models continue to display somewhat different scenarios with various
disturbances moving near or through the region and as such,
confidence in the details (specifically, precipitation) remains
somewhat lower than normal through the long term forecast period.

The mean longwave pattern remains consistent with an amplified upper
ridge remaining over the east-central pacific and generally
northerly flow across the pacific northwest. Thus, the key factor
will be determining if a more northeasterly or northwesterly
component to the flow pattern aloft develops. Maintained some
mention of pops late Wednesday and early Thursday, but at this point
expect the snow level to remain around 1,500 feet or so through this
time period. Otherwise, below normal temperatures and only
occasional infusion of moisture can be expected through next week.


Aviation A cold front is moving through the areas this
afternoon from NW to se. Conditions are improving toVFR with -shra
behind the front with mostly MVFR with -ra ahead of the front.

Gusty s-sw surface wind will shift to out of the w-sw, but
gustiness will continue into tonight, with gusts as high as 30 kt
for the interior and 40 kt at the coastal sites. Winds decrease
tonight and cold air Sunday introduces a chance of snow mixed in
with rain in showers. Showers Sunday may bring a return to MVFR

Pdx and approaches... Improvement toVFR should generally last
through the forecast period with occasional brief MVFR in heavier
showers. South to southwest wind gusts near 30 kt expected thru
02z Sun then slowly dropping off overnight. May see some -rasn
and MVFR CIGS with showers Sunday, but expect little to no
accumulation during the day. Bowen

Marine Seas currently 11 to 15 ft with wind gusts 30 to 35 kt
across the local waters. Expect seas to continue to rise through
tonight with an approaching low pressure system pushing fresh
swell this way. A cold front has passed through the waters with
wind directions having shifted to out of the west rather than
more south.

Not a ton of change in the forecast for the next 24 hours. Still
expect peak seas during the day Sunday 18 to 20 ft near shore and
20 to 24 ft offshore. Seas should peak Sunday morning further
north and early Sunday afternoon further south before decreasing
Sunday night into Monday. Winds will drop some this evening, but
pick up again as the low pressure system approaches late tonight
and into Sunday morning. The peak winds will be beyond about 15
nm offshore.

After this initial system through Sunday night, conditions become
benign until late in the week. There is the potential for a
system to increase winds and seas again Thursday, but confidence
is low in any individual solution that far out at this point.

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.
