Strong gusty north winds will develop for areas from cape blanco southward Monday afternoon and Monday night. Gusty north winds and areas of steep seas are expected Tuesday into Wednesday, mainly across the outer waters and from cape blanco southward.

Updated aviation discussion
Discussion The forecast area is transitioning from a wet,
unsettled pattern to a dry and warm one as an upper ridge of high
pressure builds over the region. Weather impacts to the area will be
minimal over the next week, and forecast challenges will center
around how warm temperatures become (especially curry county coast)
and nighttime morning fog coverage and duration.

Midlevel moisture will be decreasing tonight, but stability is
increasing, and low level soil moisture remains high and will
support low clouds and fog in most west side valleys and some east
side valleys. Model data suggests these clouds will lift and clear
by mid to late Monday morning.

Please see the previous discussion below for more details on the
upcoming warm and dry conditions.

Aviation 23 06z TAF cycle... We are transitioning from an
unsettled, wet pattern with plenty of mountain obscuration and a mix
of MVFR ifr ceilings to a dry and warm pattern with areas of valley
morning late night fog and low clouds.

Tonight, expect ifr CIGS visibilities to develop along the coast and
into the umpqua with lifr ifr expected late tonight and Monday
morning. Coastal fog low clouds should clear by mid Monday morning
due to drying, east flow aloft. Areas of patchy fog are expected to
develop 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. East of the cascades, enough data
suggests a period of MVFR to ifr conditions late tonight into Monday
morning. We have added ifr conditions at klmt late tonight through
late Monday morning.

Monday afternoon should featureVFR conditions everywhere. -sk

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

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
