Synopsis for the southern oregon coastal waters..A thermal trough will strengthen along the coast through Friday. Conditions hazardous to small craft will continue across all of the waters with the most hazardous conditions, including gale force winds and very steep seas, occurring from 5 nm to 40 nm offshore from gold beach south. Gusty north winds and choppy seas will persist into the weekend. The thermal trough will weaken Sunday, and winds and seas will diminish at that time.

Discussion
Satellite is showing lingering clouds north of the umpqua divide
and along the northern sections of the coast. Elsewhere, cumulus
clouds are scattered across northern california and southern
oregon this afternoon. With the zonal flow continuing aloft, near
normal temperatures are expected across most areas for tomorrow.

The exception will be brookings as thermal trough will bring
warmer than normal temperatures to that area.

The thermal trough will persist for the start of the weekend
before moving farther inland on Sunday. When the thermal trough
moves inland, we'll see high temperatures in the mid to upper 90's
in most locations in the west side valleys. This is the warmest
time of year and these temperatures will only be roughly 5 degrees
above normal.

With a trough approaching, the concern then turns to the
potential for thunderstorms. As this trough approaches, it will
ingest a tropical disturbance and bring that disturbance north
into the region. After looking over the thermodynamic profile
Sunday night into Monday, we were not that excited about the
potential for thunderstorms. There is a little bit of cape, but
the atmosphere appears too stable to support thunderstorms.

Convective inhibition is showing values from -25 to -50, which is
pretty healthy for weakly forced situations. Overall, we'll keep
an eye on thunderstorm potential Sunday through Monday.

Eventually, a cold front will approach the coast Monday night
into Tuesday. Models do show some spotty precipitation in the
forecast along the coast and this situation could very well
warrant a mention of rain near north bend, but we decided to keep
it out the forecast at this time. Temperatures will cool down
about 5 degrees Tuesday into Wednesday as this relatively cooler
air and a trough moves through.

Finally, this trough will move eastward and we'll have a brief
period or ridging as the four corners high builds towards the
pacific northwest. High temperatures will rise into the mid and
upper 90's towards the tail end of next week.

Aviation For the 18 18z tafs... Terrain obscuration and MVFR
cigs will continue for the umpqua valley this morning. Skies
will start to clear andVFR will prevail for this afternoon across
the region.

It appears the air behind this front,which moved through this
morning, is quite dry. As a result, model guidance is having
trouble predicting MVFR CIGS tonight. However, we feel that MVFR
an ifr CIGS remain a possibility as there should be some lower
level moisture in the umpqua valley.

Marine Updated 200 pm pdt Thursday 18 july 2019... A thermal
trough will strengthen along the coast today and Friday.

Conditions hazardous to small craft will develop across all of the
waters this afternoon. The most hazardous conditions, including gale
force winds and very steep seas, will occur from 5 nm to 40 nm
offshore from gold beach south. Gusty north winds and choppy seas
will persist into the weekend. The thermal trough will weaken
Sunday, and winds and seas will diminish at that time.
