Synopsis for the southern oregon coastal waters.. A thermal trough along the coast will continue to result in gusty north winds today. Seas will remain very steep south of cape blanco, with steep seas elsewhere. A frontal system moving through north of the area Saturday will brush by resulting in some decrease in winds and seas. Winds increase again Sunday causing wind wave dominated seas to build to a new peak on Monday. The thermal trough is expected to push inland and weaken on Tuesday, allowing conditions to improve along and near the coast.

Update
The forecast for this morning into early afternoon has been
updated to better reflect fog and low clouds along and near the
coast and across douglas county.

Discussion
Cool temperatures this morning combined with lingering low level
and ground moisture from recent rainfall have resulted in quite a
bit of low clouds and fog across NW portions of the area this
morning. These low clouds and fog are lingering across SE douglas
county and portions of the coquille and umpqua river valleys. It
is likely to take until early afternoon for this to completely
dissipate. Otherwise, a warming trend will continue today, then
tail off a bit over the weekend, before ramping up, likely, to the
highest temperatures of the year Tuesday into Wednesday. Btl

Aviation For the 23 12z tafs... Along the coast, in the coastal
valleys, and over the coastal waters... Isolated ifr CIGS vsbys in
low clouds and fog will clear toVFR by mid-morning Friday.VFR
conditions will then prevail into Friday evening, then areas of ifr
cigs vsbys in low clouds and fog will develop Friday night,
persisting into Saturday morning. Over the remainder of the
area...VFR conditions will prevail into Saturday morning, except for
patchy ifr CIGS over the umpqua basin that will clear toVFR by late
Friday morning.

Marine Updated 915 am pdt Friday, 23 august 2019...

a thermal trough along the coast will continue to result in gusty
north winds today. Seas will remain very steep south of CAPE blanco,
with steep seas elsewhere. A frontal system moving through north of
the area Saturday will brush by resulting in some decrease in winds
and seas. Small craft advisory conditions are expected south of cape
blanco Saturday into Saturday night. After that, winds will
strengthen again Sunday with an area of gales possible again south
of CAPE blanco from late Sunday morning through Monday evening. The
thermal trough is expected to push inland and weaken Tuesday
allowing conditions to improve along and near the coast. Btl

Fire weather Updated 300 am pdt Friday 23 august 2019...

there was little change made to the forecast, mainly fine tuning of
the relative humidity forecast. A strong warming and drying trend
will begin today. The warmest and driest conditions are likely on
Tuesday, but improvement during the remainder of next week will be
barely noticeable.

While the passage of a weak, dry cold front on Saturday will not
bring any cooling, it will bring gusty westerly winds east of the
cascades with afternoon and evening speeds stronger than normal at
12 to 18 mph with gusts up to 25 mph.

Associated with the warming and drying trend will be night into
morning northeast winds of 5 to 15 mph over the coast range with
moderate mid slope and ridge humidity recoveries tonight through
Monday night.

The air mass will remain stable at least through Tuesday night, and
likely through Thursday morning. Model uncertainty increases beyond
day 5 with differences in the track of a closed low over the
pacific. -dw

discussion... 23 00z nam GFS ec in.

Mostly clear skies prevail across the area this morning, except for
patches of low clouds and fog along the coast north of CAPE blanco,
in the coquille valley, and in the umpqua basin.

An upper ridge is building over the area along with a thermal
trough offshore. A strong warming trend will affect all areas
through Friday. By that time highs will be 5-10 degrees above
normal.

Short waves moving over the top of the ridge will keep it from
building any further this weekend, and this will put the brakes
on the warming trend. Saturday and Sunday highs will be about the
same as the Friday highs. A dry cold front will move through
Saturday. It won't bring any cooling, but it will bring gusty
winds to the east side Saturday afternoon and evening.

The ridge will build in more strongly next week, and the thermal
trough will move inland. That's when it will get really hot over
the area. Another strong warming trend will occur Monday into
Tuesday, and the Tuesday highs will be 10-15 degrees above normal.

The medford high will be near 100 degrees Monday and will exceed
it Tuesday. Wednesday will be similar to Tuesday with mostly clear
skies and hot temperatures.

At some point the ridge will break down and the possibility of
thunderstorms will enter the forecast with slightly cooler
temperatures. The latest GFS run continues to show that lis will
remain positive Wednesday afternoon and evening with pws of around
0.66 inches, which is too stable and marginally dry. However, on
Thursday afternoon and evening there is a significant area of
negative lis from around crater lake southeast through the east
side, and the pws rise to 0.75 to 1.0 inches. That is sufficient
for thunderstorm activity and thus will keep the current forecast
of a slight chance of thunder at that time and location.

Mfr watches warnings advisories
Or... None.

Ca... None.

- small craft advisory until 5 am pdt Sunday for pzz356-376.

- hazardous seas warning until 5 am pdt Saturday for pzz356-376.
