Synopsis for the southern oregon coastal waters..Winds will remain relatively calm for much of the next week. Seas will build Tuesday night ahead of a weak cold front and may become high and steep as it passes on Wednesday. A thermal trough could develop late this week, producing gusty north winds and wind driven seas by this weekend.

Discussion 21 12z NAM in. 12 12z GFS in through 84hr.

The pacific northwest is now on the tail end of what was a very
wet weekend. The long wave upper trough that shepherded the wet
systems onshore is now over the intermountain states and a strong
ridge remains offshore. The medford CWA is under north northwest
flow aloft between the two systems. Light showers persist this
morning as there are still short waves diving down the backside of
the trough.

Those showers will end later today as the last of the short waves
clears out and the offshore ridge builds in more strongly.

However, a few more fronts will impact northern portions of the
medford cwa, supported by short waves moving over the top of the
ridge.

A warm front will move north through the area Tuesday. In terms of
precipitation, only the most northern portion of the front will be
active. The north coast, umpqua basin, and the adjacent cascades
may see some light precipitation, but the rest of the area will
remain dry. Snow levels will initially be 3000-4000 feet, but they
will rise to near 7000 feet with the warm front.

The trailing cold front will move onshore Wednesday. The
associated precipitation will be a bit more widespread, but still
limited to the cascades west and siskiyous north. Amounts will be
very light. Snow levels will drop back down to around 5000 feet
behind the front.

Any straggling showers will end Wednesday night as the upper level
ridge continues to build into the west coast. The area will then
go into an extended easterly low level flow scenario which will
last from Thursday into the weekend. It will be dry with gradually
worsening overnight rh recoveries over the ridges. However,
overnight through morning low clouds and fog will persist in the
valleys. Some areas might not clear at all.

The coquille river at coquille remains in minor flood stage. The
spring tide has exacerbated the situation, but it now cresting
just below moderate flood stage. See the flsmfr for more
information.

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 800 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

Mfr watches warnings advisories
Or... None.

Ca... None.

Pacific coastal waters... Small craft advisory for hazardous seas

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
