Synopsis for the southern oregon coastal waters..Weak low pressure will move through the waters this morning. High pressure will then build southwest of the area this afternoon through Tuesday. A warm front will move north of the area Tuesday with light to moderate south winds. A cold front will move into the waters Wednesday. Seas will build Wednesday due to an increasing west swell. A thermal trough may develop late in the week, producing gusty north winds and wind driven seas.

>updated aviation discussion.

Discussion Current radar is indicating showers have picked up
in coverage across portions of southern oregon and northern
california. Overall, the precipitation is not expected to be as
heavy, or as long-lasting as what we experienced this past
weekend. These showers are in association with an upper-level
trough moving across our forecast area. This upper level trough
was visible on shortwave IR satellite earlier, as indicated by the
counter-clockwise rotation of the clouds. This trough is digging
southward, and as a result, the showers over our area also have a
southeastward track. Snow levels are already lower--around 3000
feet or so, and they will hover as such today before crashing
toward the west side valley floors tomorrow night. That being
said, the general precipitation will be coming to an end tomorrow
before that happens. Until that happens, a winter weather advisory
is in effect until 4 am for the cascades, siskiyous, and the
marble mountains in the kalmiopsis wilderness. Will allow that to
continue for now, and will need to evaluate how things are going.

Please see the wswmfr for more details.

Meanwhile, the other important information is that the coquille
river at coquille remains in minor flood stage. The spring tide
associated with the lunar eclipse which occurred earlier tonight
has caused the coquille river to begin rising. The river will rise
rather quickly, and will crest around 6 or 7 am today. The river
is expected to crest at 22.7 feet which is only a few inches below
from moderate flood stage (23 feet) where farm structures may be
impacted. Of course, it is difficult to determine just how he
tidal effects will affect the river, but the current forecast is
well on track. If there is a heavy shower that moves over the
area, the river could easily gain the extra water needed to push
it into moderate flood stage. So, if you live near the coquille
river, stay tuned to the updates to the flood warning. See the
flsmfr for more information. Otherwise, the rogue river at agness
has fallen below flood stage and remains at or near bank full.

The river will continue to decrease during the day today. As a
result, have cancelled the flood warning there.

Showers will generally decrease in intensity and coverage today as
a ridge of high pressure builds in. This will create a period of
rather benign weather, with fog and low clouds filling into the
west side valleys, as is customary during the winter. This fog low
cloud combination will linger throughout the days, keeping
temperatures from reaching their maximum potential. Low
temperatures will hover around freezing for areas west of the
cascades (except for the coast which will see lows in the upper
30s). Meanwhile, areas east of the cascades will see temperatures
dip into the teens with some of our traditionally colder areas see
temperatures drop into the single digits over this week with
tomorrow night being the coldest night. This overall pattern will
last for most of the week.

A frontal boundary is expected to drift over the ridge bringing
some precipitation to areas north of the umpqua divide on
Wednesday, but otherwise don't see this system becoming impactful
at this time. -schaaf

Aviation For the 21 12z tafs... Conditions are still rather
unstable early this morning. The last gasp of showers are moving
southeast over the umpqua basin towards medford. This should be
enough to prevent low clouds and fog from developing at medford,
thereforVFR ceilings are expected to continue for most of the taf
period. Further north, conditions are becoming more stable and there
may be enough clearing for MVFR ceilings and reduced visibility at
roseburg and north bend around daybreak. The lower conditions are in
both tafs, but confidence is not high the lower conditions will
develop. There will also be local mountain obscuration near showers,
and at northerly facing slopes this morning.

Skies have cleared out at klamath falls and given the amount of
precipitation there this pas weekend, there is concern for patchy
fog and reduced visibility in the vicinity of the airport around
daybreak for a few hours, otherwiseVFR conditions will continue
through the TAF period.

Stable weather is expected tonight, this along with recent rainfall
will likely lead to lifr ceilings and visibility for all westside
valley locations, including medford, roseburg and merlin airports
later this evening. -petrucelli

Marine Updated 200 am pst Monday 21 january 2019... Weak low
pressure will move south of the waters this morning. High pressure
will then build southwest of the waters this afternoon and remain
there through at least Wednesday. Meanwhile a warm front will
move north of the waters Tuesday afternoon, then a weak frontal
system will move into the area Wednesday. Winds this week are
expected to remain relatively weak. Seas will subside to a minimum
on Tuesday, then a west swell will increase Wednesday resulting
in small craft conditions. Models do show the possibility of a
thermal trough developing late this week, and this could produce
gusty north winds and wind driven seas, strongest in the outer
portion of the waters and south of CAPE blanco. -petrucelli
