Synopsis for the southern oregon coastal waters..Southerly winds will continue through Wednesday as a weak front slowly moves towards the waters. The front will weaken and move inland late Wednesday, then a moderate west swell arrives Wednesday night into Thursday. A thermal trough will develop along the coast Wednesday night and Thursday and result in gusty northerly winds, mainly south of cape blanco. Steep combined seas are possible across all the waters on Thursday. Then, on Friday, steep seas and gusty northerly winds may linger across portions of the waters south of cape blanco.

Updated aviation discussion
Discussion Current satellite imagery is showing some high
cirrus clouds moving over southern oregon and northern california
from west to east. Overall, the airmass will be persistent to what
occurred last night, and temperatures will be very similar to what
occurred last night across the area. The only question will be
whether or not the cirrus clouds will move slow enough to keep
temperatures a bit warmer than last night. Have dropped
temperatures a little bit tonight from the day shift, but not as
low as they were last night due to these clouds. Otherwise, the
forecast is on track, and am not making changes. -schaaf

Marine Updated 800 pm pst Monday 12 november 2018... Southerly
winds will continue through Wednesday as a weak front approaches.

This front will very slowly move into the area and thus sub-advisory
south winds and seas continue through Tuesday. The front finally
moves onshore Wednesday, and we're not expecting any significant
impacts to the coastal waters until late Wednesday night or Thursday
morning when a steep westerly swell around 10 feet moves in behind
the front.

A thermal trough and northerly winds develop Wednesday night into
Thursday. Steep combined seas are possible on Thursday due to a
combination of west swell and wind seas. Small craft advisory level
winds are also possible on Thursday, mainly south of CAPE blanco in
the waters beyond 10 nm from shore. Steep seas and areas of gusty
northerly winds may persist into Friday as the thermal trough
remains in place along the coast. -cc keene

Prev discussion issued 405 pm pst Mon nov 12 2018
discussion... A high pressure ridge is in place today bringing
warm daytime temperatures and dry conditions. A weak front will
approach the area tonight and Tuesday, then weaken further as it
moves inland on Wednesday. There is only a slight chance for light
rain along the coast. Elsewhere expect dry weather to continue
and the front will only bring some clouds into the area wedensday.

Of note, ahead of the front expect southerly winds to develop over
the area Tuesday. This may result in some patchy smoke moving into
the area from fires to the south. Current high resolution
forecasts from the hrrr indicate smoke expected to move into
siskiyou and modoc counties during the day Tuesday, then patchy
smoke or haze may spread into portions of southern oregon Tuesday
afternoon and Tuesday evening. Winds become more westerly on
Wednesday though so any smoke that moves into the area may shift
east on Wednesday.

Behind the front, a high pressure ridge will rebuild over the
region Thursday into the weekend. This will bring continued warm
daytime temperatures and dry weather to the area through at least
Sunday.

Aviation... For the 13 06z tafs...VFR will prevail across the
forecast area, outside of the umpqua basin, for the next 24 hours.

Shallow moisture in the umpqua valley will likely bring local
ifr lifr ceilings visibility back to roseburg again late
tonight Tuesday morning. These ifr lifr conditions will improve to
vfr by late Tuesday morning.

Some low clouds were observed this afternoon near the coast of
southern oregon, and these are expected to move northward through
tomorrow, but confidence is low that it will impact any of the
coastal terminals. Keene spilde
fire weather... Conditions will remain critically dry through
Wednesday morning, then improve. But, humidities will not be high
and no rain is expected over the next 7 to 8 days, through Tuesday.

East to southeast winds have decreased today. They will increase
slightly at inland locations tonight and continue at 5 to 15 mph
into early Tuesday morning, while southerly winds develop at the
coast and continue into Tuesday evening. These weak to moderate wind
speeds will not reach red flag warning criteria, but relative
humidity recoveries both tonight and Tuesday night will be poor to
moderate again over the higher terrain across the region.

Recoveries will be worst in siskiyou county.

The improvement in conditions on Wednesday will be due to a very
weak front that will bring a slight chance of very light rain to the
coast then pass through the area late Tuesday in Wednesday. Despite
the improvement, conditions will still be drier than normal. Mild
and dry weather will persist through the forecast period, with light
east winds returning Wednesday night. East winds will continue
through the weekend. Strength of winds later in the week through
early next week is uncertain, but they are unlikely to be as strong
as during this past weekend's episode. The pattern may finally
change and bring a chance of rain beyond day 7. -dw
