Synopsis for the southern oregon coastal waters.. Gusty north winds and steep wind driven seas will persist south of cape blanco through tonight while a combination of fresh swell and wind waves produces areas of steep seas to the north. A surge of southerly winds and fog is likely to push from california to north of our area through the day Tuesday, with relatively calm conditions expected into Thursday. North winds and steep seas are expected to return by this weekend.

Discussion Hot weather with somewhat heightened thunderstorm
chances is on tap for the next several days, then weather will
transition to cooler, and at times clearer, during the second half
of the week.

Air quality in the rogue and illinois valleys improved
substantially in the rogue valley yesterday afternoon and evening
as offshore winds at the surface pushed smoke from the taylor
creek klondike fires towards the west southwest, thus most smoke
seen in inland areas was aloft west of the cascades and east of
the coastal range was primarily aloft. East of the cascades, the
miles fires continue to bring smoke to much of klamath county, and
the watson creek and stone fires in lake and modoc county
respectively have been very active, bringing copious smoke to
surrounding areas and areas downwind. Air quality will diminish
this afternoon west of the cascades, even in the umpqua basin and
coastal areas... North flow will bring smoke down from fires up in
british columbia, in addition to smoke from fires here.

The main concern in the near term is thunderstorm potential. An
upper trough over the area will shift northeastward today, and a
secondary closed low will develop over the area today into
Tuesday. This afternoon and evening, instability is marginal but
not weak enough to completely rule out thunderstorms over the
cascades and to the east. Tuesday afternoon and night, the 20 00z
gfs and NAM have positioned the low farther east than previous
runs. So, decided to trim the area of schc thunderstorms to be
concentrated farther east. Due to climo, was hesitant to remove
tstorms from the cascades, but the likelihood of thunderstorms in
the cascades looks lower than it did in previous days, and the day
shift can assess the situation when the 12z models come in.

Wednesday into Thursday, the low should fill and shift out of the
area, and we'll transition to onshore flow, and temperatures will
start a slight downward trend day to day. In other words, highs
will be within a few degrees of climo normal (based on years 1980
to 2010) by the end of the week. Thursday into Friday, a dry cold
front will push into the area. So, the slight cooldown should
continue into the weekend, and more importantly, this front should
temporarily clear smoke out of the area. Sunday into Monday, a
stronger front will move into the area, bringing potential for
precipitation and maybe just maybe below normal temperatures.

Aviation For the 20 12z tafs... Along the coast, MVFR ifr
stratus fog will impact the coos douglas coasts through midday
Monday. Ceilings should scatter out around 20z, but wildfire smoke
pushing in from the north may limit visibility to MVFR thereafter.

South of CAPE blanco, expect mostlyVFR, but a southerly finger of
stratus fog will affect the immediate coast near brookings
approximately through 18z. Wildfire smoke may result in MVFR at
times there Monday afternoon.

Stratus fog will also push into the lower portions of the umpqua
basin overnight, but stay NW of roseburg.VFR will give way to
MVFR visibility in smoke at roseburg due to midday afternoon nne
breezes pushing smoke in from the north.

Vfr will prevail at medford through most of Monday morning. However,
expect MVFR smoke to return late Monday morning into Monday
afternoon from the north. Elsewhere, expect wildfire smoke to at
least occasionally reduce visibility to MVFR. Ifr and local lifr
visibility should be expected immediately down wind of the active
wildfires. There is a slight chance of thunderstorms near the
cascades and over the east side late Monday afternoon into Monday
evening, but confidence wasn't high enough to include in the klamath
falls TAF yet. -spilde

Marine Updated 100 am pdt Monday 20 august 2018... A thermal
trough will continue to produce gusty north winds and steep wind
driven seas through tonight, but conditions should stay well within
small craft advisory limits. The gustiest winds and steepest seas
will occur south of CAPE blanco through this evening with advisory
fresh swell continuing through Monday night. Otherwise, smoke from
wildfires to our north could create minor visibility issues
tomorrow. Then, a quick break is expected beginning Tuesday with a
coastally trapped wind reversal pattern. This will bring southerly
winds and fog northward from california to at least florence on
Tuesday. After the mid-week break and a weak frontal passage, the
next thermal trough builds in late Thursday or Friday. This will
bring another round of gusty north winds and steep seas. -schaaf

Fire weather Updated 330 am Monday august 20th... An upper trough
currently sitting over the area will be the main weather maker
today, bringing potential thunderstorms to the cascades and eastward
this afternoon and evening. Thunderstorms will likely be slow-
moving, with stearing flow fairly light. Possibility of dry
thunderstorms is lower than in a situation with fast-moving
thunderstorms. But, very dry vegetation will make any lightning
problematic. Tuesday afternoon and evening, the thunderstorm threat
looks to be concentrated mainly in the southeastern portion of the
forecast area. I was hesitant to remove thunderstorm wording from
the cascades for Tuesday afternoon, given thunderstorm climatology.

But, stay tuned for updates as the day shift further refines the
forecast based on new model runs.

A dry cold front will push into the area Thursday into Friday,
bringing a slight cooldown and periods of breezy winds, particularly
on the east side. Sunday into Monday, a stronger front will move
into the area, bringing potential for precipitation and another
round of breezy winds.

Mfr watches warnings advisories

Ca... None.
