Discussion No updates needed this evening. A front continues to
dissipate along the coos coast this evening. Despite guidance
indicating the potential for light rain over the far north coast
this evening, observations and webcams show nothing, and thus dry
weather is the expectation tonight. We are seeing a fair amount of
cloud, so that will help hold temperatures up compared to recent
nights. Tomorrow an upper ridge will begins building over the
pacnw, and this will lead to sunnier and slightly warmer weather
for much of our area. This also leads to the development of a
thermal trough at the coast and the gusty offshore (northeast)
winds that often accompany them starting Friday and continuing
into the weekend. This combined with a drying airmass and
continued unseasonably dry fuels will create elevated fire
conditions that are rather unusual for november. Long nights and
good humidity recoveries in the valleys help to mitigate this
somewhat, but the mountains will remain dry and breezy at times.

Please remember this if you plan to venture into the mountains any
time through this weekend. -wright

Marine Updated 800 pm pst Wednesday 14 november 2018... North
winds will increase through tonight and into Thursday, producing
increasing wind driven seas. Meanwhile, northwest swell will build
through Thursday morning. The combination of these two wave groups
will generate chaotic seas hazardous to small craft. The main area
of concern will be 10 to 30 nm away from shore south of gold beach.

This area will have the strongest winds. However, since the swell
is the dominant wave in this scenario, we decided to stay away
from a hazardous seas warning for the area mentioned above.

A low to moderate west swell will remain the forecast through next
week. North winds will weaken by Sunday, then shift to the south
and increase into the middle of next week.

short term... A weak front is moving into the coast and will
weaken and dissipate early this evening. Some light rain has
fallen at the coast near coos bay and northward. Otherwise dry
conditions have continued across the area today with an upper
ridge in place. Some haze and smoke from fires to the south has
lingered over the area today and is expected to shift southeast
tonight. Smoke is mainly aloft and is patchy.

Models remain in good agreement showing the high pressure ridge
strengthening Thursday into Friday with a surface thermal trough
developing along the coast. This will bring a stable, dry air
mass to the region. Expect gusty north winds over the coastal
waters Thursday afternoon and evening with breezy north to
northeast winds inland along the coast. Offshore northeast to east
winds will bring breezy winds to the coastal mountains Thursday
night into Friday morning.

Friday night into Saturday, the ridge and thermal trough will
build northward. Expect continued east winds over the mountains
with winds increasing in the southern oregon cascades Friday
night into Saturday. Saturday, an upper level shortwave will move
down the east side of the ridge. This disturbance is expected to
remain east of the area and expect little impact. East side
locations may see temperatures lower some late Saturday into

Long term... Monday through Wednesday... Models show more
variability in how strong the upper ridge will be early next week
and when it may weaken or break down. The ensemble mean GEFS and
gfs forecasts are stronger with the ridge and slower to break down
the ridge compared to the ecwmf. The GEFS and GFS would favor
continued dry conditions through Tuesday, followed by an upper
trough moving into the region around Wednesday of next week.

However the GFS has trended weaker and drier with this system next
week. In contrast, the ECMWF is quicker to break down the ridge
and continues to show a front and upper trough bringing
precipitation into the area Tuesday night into Wednesday. Overall,
expect a chance for precipitation by Wednesday but confidence is
low on the details of the strength and timing of this system. So
will monitor this portion of the forecast with future model runs.

Aviation... For the 15 00z tafs... A dissipating front will bring
some MVFR ceilings to the coast and the umpqua valley this evening.

Vfr will prevail elsewhere. Smoke from wildfires in california will
maintain a haze across the area, but it should not be thick enough
to restrict visibility.

Overnight into Thursday morning, low-level moisture along the coast
and into the umpqua valley will lead to areas of ifr low clouds and
fog, butVFR will return in the afternoon.VFR will persist
elsewhere. -spilde

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 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.
