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
Aviation 18 18z TAF cycle... Fog and low clouds are lifting very
slowly in the west side inland valleys this morning, and may not
break out at all in the grants pass area. Similar conditions as this
morning are expected in the west side valleys Sunday morning, but
will break out a little earlier as a front moves into the area.
Marine Updated 250 pm pst Saturday 18 november 2017... High
pressure will remain over the coastal waters with mostly light winds
and low seas today. South winds will increase again ahead of the
next front Sunday with gales and very steep seas Sunday afternoon.
Confidence is high that seas will build 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 night
but are expected to increase to near gale again on Tuesday. As a
result we have extended the gale watch through Wednesday. Unsettled
weather will then continue through much of next week. -sven

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.
