Discussion Minor changes are being made to low temperatures for
tonight in this evening's update. Due to the persistent stratus on
the west side today, high temperatures were cool, and this has led
to current temperatures that are from 2 to 6 degrees cooler than
last night at this time. There are some high clouds over us now,
but there is a definite back edge to these clouds, so we expect
skies to be clear much of tonight above the valleys. This is a
long winded way of saying that I lowered low temperatures for
tonight in many places, but especially on the west side. There is
a frost advisory out for much of the umpqua basin, and this looks
ok. The rest of the area inland from the coast will be cold and
frosty, too, but we're past the growing season there.

Stratus and fog has already formed in most of the west side
valleys. Tonight will be a cold, foggy one, and the forecast
largely has this all covered. -wright

Aviation 19 06z TAF cycle... Lifr low clouds and fog are
developing in valleys west of the cascades this evening. This lifr
is likely to thicken into early Sunday morning. But, it will
dissipate a little earlier than on Saturday as a front moves into
the area. Otherwise,VFR CIGS will develop across the area Sunday
afternoon into Sunday evening. -dw

Marine Updated 830 pm pst Saturday 18 november 2017... High
pressure will remain over the coastal waters with mostly light winds
and low seas tonight. South winds will increase again ahead of the
next front Sunday with gales and very steep seas expected by Sunday
evening, though winds will not be as strong near shore south of gold
beach. Confidence is high that seas will build rapidly to around 14
feet Sunday night from gold beach north, with seas possibly building
to 17 feet north of coos bay. Winds could decrease some Monday but
are expected to increase to near gale again on Monday night and
remain strong through mid-week. As a result a gale watch is in
effect through Wednesday. Unsettled weather will then continue
into next weekend. -sven dw

short term... Tonight through Tuesday... Fog was slow to burn off
in the rogue and illinois valleys today and with patches of fog
lingering in the southern portion of the illinois valley. Because
of this, high temperatures will be much cooler than previously
forecast for locations in these valleys. This break from the fog
will be short lived with only a few hours of filtered Sun thanks
to thin cirrus streaming over the area. Another clear, cold night
is expected tonight and this will make for a repeat of last
night's conditions. Fog will fill in the valleys west of the
cascades and another frost advisory has been issued for the umpqua
and coquille basins.

Fog should be less stubborn Sunday as it will be a transition day
back to an active pattern. The ridge axis will shift to the east
and another strong front with tropical origins will make it's way
toward the area Sunday afternoon. Ahead of this front, winds will
increase and have issued wind advisories for the shasta valley
and portions lake and modoc counties in the traditionally windier
locations. Details on this can be found at npwmfr. It could be
gusty in the rogue valley as well Monday afternoon, but have held
off on an advisory for now. Will see how nearer term models
resolve the winds with future model runs and evaluate further.

Heavy rain will also accompany this front and should begin at the
coast by late Sunday evening. The heaviest rain is expected
overnight Sunday into late Monday morning focused on the southern
portion of the coastal range. Although rain will be heavy at
times, it's nothing more than what we've seen in recent events.

Snow levels with this front start off around 6,000 feet, rising to
around 9,000 feet by Monday morning thanks to the tropical nature of
the moisture. Because of this, snow impacts should be minimal and
restricted to the higher passes for a brief time.

By Monday afternoon, precipitation rates begin to taper off as
the bulk of the moisture shifts to the north of the forecast area.

There will be relative lull in winds overnight Monday. The area
will still be under the influence of moist, southwest flow Tuesday
but it seems models have shifted the focus of the heaviest
precipitation into northern oregon and washington. As a result,
qpf amounts have been lowered over the area for the Tuesday
system, with the most precipitation expected over the southern
coastal mountains. Southerly winds will still be a concern
however, and there could be another round of wind headlines
Tuesday. Snow levels will remain high, above 9,000 feet, as we
head into the extended period. Br-y
long term... Wednesday through Saturday... Models continue to show
agreement that the area will remain under the influence of southwest
flow through Thursday as a ridge remains centered inland to the
east and a trough is centered off the pacific northwest. With this
pattern, also expect high snow levels of 8000 ft or more Wednesday
and Thursday. The 12z models indicate that a front may linger near
or just inland of the coast on Wednesday into Thursday and bring
continued areas of rain. Based on the latest models, there is the
potential for widespread rain showers on thanksgiving day.

Another front is forecast to move into the area from the west-
northwest and bring additional rain Thursday night into Friday. Snow
levels are expected to lower to 6000 to 7000 feet on Friday. Models
support a brief period of dry weather late Friday with showers
expected to diminish by Friday evening and night as the upper ridge
builds over the region. This break may be brief though with models
indicating a moist frontal system moving into the area Saturday into
Saturday night. The GFS continues to be faster and moister with this
system. -cc

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.
