Discussion
Short term This evening through Wednesday night... The front
producing rain across the area today is washing out and weakening,
and while showers are dissipating quite rapidly on radar this
afternoon, some areas of rain surely persist under the scope of
the radar beam. Precipitation will continue to diminish through
the evening, and should mostly clear out of the area overnight,
although west facing slopes along the cascades and coastal ranges
may see some light rain continue into the early morning hours.

Beginning tomorrow, high pressure will build in for the first
half of the week. This will result in drying and warming
conditions, as well as prevailing easterly winds in the lower
levels. With the moisture now in the ground and cooler
temperatures settled in, this east wind is likely to create
strong overnight inversions, trapping air within the valleys and
limiting the mixing with the drier air aloft. Fog will be a
concern each morning in the west side valleys, but fog is
possible east of the cascades as well, especially Monday morning.

If fog forms, it will limit the daytime highs significantly, but
if it does not, unseasonably warm temperatures of 5 to 10 degrees
above normal are not out of the question for much of the region.

Also of note, a chetco effect is a likely byproduct of these east
winds, and temperatures along the southern coastline near
brookings could approach 80 by Tuesday afternoon.

On Wednesday, a weak front will approach the region from the
north. The ridge overhead will severely limit its ability to push
into our forecast area, and will likely keep any measurable
precipitation well to our north. While the front will be dry,
cloud cover will increase and temperatures will cool slightly, but
little else will mark its passage. High pressure will quickly
regain control as we head into the extended term. -bpn

Long term Wednesday through Sunday night... The extended period
continues the warmer and drier trend. Easterly winds will
dominate all of southern oregon and northern california. This will
allow for temperatures to be around 10 degrees warmer than normal
for this time of year across the board. Humidity values will also
be lower than normal through the time period, so this may help
there be less fog in the west side valleys in the later stages of
the week. Bs

Aviation 22 18z TAF cycle... A mix of MVFR ifr ceilings and
visibility continues today in moist onshore flow ahead of another
front, and this general condition is expected to continue through
today for areas form the southern oregon cascades west (especially
for areas along the coast and into douglas county. South to
southwest winds will remain breezy to gusty through this afternoon
over the higher terrain, and east of the cascades, gradually
diminishing this evening. Mountain obscuration will continue to
affect most of the forecast area through today with widespread
obscurations from the southern oregon cascades westward. Mountain
obscurations will decrease this evening and tonight.

This evening into tonight, expect ifr CIGS visibilities to develop
along the coast and into the umpqua with lifr ifr expected late
tonight and Monday morning. Areas of patchy fog are expected to
develop at at other valleys west of the cascades, including kmfr, as
well this evening and tonight... With areas of ifr CIGS vis
developing early Monday morning. This is based on the high soil
moisture and increasing stability leading to the chance for some
fog mist and ifr conditions. -cc

Marine Updated 250 pm pdt Sunday 22 october 2017... Seas will
remain steep to very steep through this afternoon and will be
dominated by a 12 second west swell. Very steep seas will decrease
this evening. However, steep seas will persist across the waters
this evening through Monday night. Winds will become northerly on
Monday with strong gusty winds developing for areas from CAPE blanco
south beginning Monday afternoon and evening. Small craft advisory
level winds and seas are expected to persist through Wednesday
morning for areas from CAPE blanco south, then gales are possible
beginning Wednesday afternoon. Areas north of CAPE blanco are
expected to maintain steep seas through Monday night, then areas of
small craft advisory level winds and seas are expected in the outer
waters beyond 10 nm from shore and near CAPE blanco Tuesday into
Wednesday morning. Small craft advisory level winds and seas may
spread over much of the waters north of CAPE blanco late Wednesday
into Thursday. Winds are forecast to lower Thursday night.

Friday into Saturday, the concern shifts to a long period swell
which is forecast to build into the waters. This swell is forecast
to reach 10 to 12 feet at 20 seconds by early Saturday morning. -cc

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
