What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis for the southern oregon coastal waters..Gusty north winds and steep wind driven seas will continue to strengthen and spread north this evening, with gales and very steep and hazardous seas expected south of gold beach late through Sunday morning. Conditions will improve slightly Sunday afternoon into Monday, but gusty north winds and steep seas are likely to continue through the week, with periods of gales and very steep and hazardous seas possible again Tuesday and beyond.

Discussion Dry weather will persist tonight with offshore flow
strongest south of CAPE blanco. Most areas will be cloud-free
overnight due to the dry offshore flow, though models indicate
just enough bl moisture that patchy low clouds could develop for a
few hours along the north coast in coos county and also portions
of the umpqua valley.

An upper ridge axis shifts overhead tomorrow resulting in a
sunny, hot day inland. Highs will be near or surpass 100 degrees
in portions of the rogue illinois shasta and lower klamath river
valleys. Since the surface thermal trough will be headed inland,
coastal locations will see a marine push that will bring ocean air
back onshore during the late morning and afternoon. So, brookings
won't be as warm as it was today. Marine stratus may also arrive
at the coast early in the afternoon.

By Sunday evening, stratus will push into all coastal areas and
some drizzle may develop later in the evening and overnight.

Clouds will infiltrate most of douglas county north of the umpqua
divide Sunday night into Monday morning. Most models are showing a
little light QPF out of a rather shallow moist layer, so if it
does precipitate, it's likely just a little light rain or
drizzle. Right now, it looks like the moist layer could deepen
just enough to spill over the umpqua divide for some clouds to
come into the rogue illinois valleys by Monday morning, but we're
not expecting any precipitation that far south. Monday will be
much cooler for most inland areas west of the cascades - about
15-20 degrees lower than on Sunday. East of the cascades, it will
still be warm, with temperatures similar to Sunday over far se
sections, but about 10 degrees lower closer to the cascades. It
should be noted that gusty north-northwest winds will develop
Monday afternoon for most locations. -spilde

Aviation For the 24 00z tafs... Offshore will maintainVFR
conditions for the rest of the TAF period. The exception to this
could be at north bend. Guidance suggest MVFR ifr CIGS could return
to the coast, north of CAPE blanco, including north bend later
tonight. Confidence remains low, as the onset of clouds will depend
on if and when onshore flow develops. For now went with MVFR CIGS at
north bend beginning roughly around 0800 utc, but ceilings may not
develop until later, if at all. Current thinking is that if CIGS do
develop, it will be short lived. However, confidence is increasing
that MVFR CIGS will return along the coast late Sunday afternoon
with onshore flow setting in ahead of a weak front. Br-y bpn

Marine Updated 730 pm pdt Saturday 23 june 2018... The thermal
trough will remain in place along the oregon coast through the
weekend, and small craft advisory conditions will persist south of
reedsport into next week. Meanwhile, very steep and hazardous seas
and occasional gale force gusts are expected south of gold beach
through Sunday morning. A gale warning remains in effect to account
for both the expected gale gusts and the likely hazardous sea
conditions.

The thermal trough pattern will be temporarily disrupted late Sunday
into Monday as an upper level trough moves just north of the area.

This will slightly and temporarily reduce winds and seas, but
conditions are likely to remain hazardous to small craft well into
next week as the thermal trough quickly re-establishes itself. There
is a chance for afternoon gales and very steep seas to return to
areas south of CAPE blanco by Tuesday or Wednesday. -bpn br-y

Prev discussion issued 252 pm pdt Sat jun 23 2018
discussion... Sunny skies prevail over the entire forecast area.

Much of the west side has reached into the 80s, and east side in
the 70s. The brookings airport hit 84 degrees earlier today, due
to the chetco effect. Expect marine clouds to return to the coast
tonight, and maybe a few making it into the umpqua basin. But,
clouds should scatter Sunday morning.

Current water vapor imagery confirms that models are on track
building a strong ridge into the pacific northwest tonight into
tomorrow, bringing essentially a one day heat wave. Temperatures
will be in the upper 90s in west side valleys south
of the umpqua divide, and expect some locations to hit 100. East
side valleys will likely reach into the upper 80s or low 90s.

Confidence is high that Sunday will be the hottest day thus far
this year... For reference, the last time kmfr cracked 100 degrees
was sept 11. The heat will be short-lived; a cold front will
approach late Sunday. Timing of this front will determine how hot
temperatures get... High clouds ahead of the front could limit
highs a few degrees. The front looks to be dry, so other than some
drizzle along the coast, the main impacts of the front will be
relatively cool, breezy conditions. Temperatures Monday will be
near normal (mid 80s over most of the cwa).

After Monday, expect a few days of uneventful zonal flow, then
mid to late next week, the area will transition to a more
progressive pattern. A weak cold front will pass through the area
Thursday, bringing a dip in temperatures from Wednesday to
Thursday. Any precipitation will likely be directed to northern
oregon and southern washington, but northern douglas and klamath
county could squeeze a few drops out.

The GFS develops an upper low over the northern rockies and
drifting southward Saturday, which could bring some showers to
eastern oregon. Confidence is low as this time frame has been
highly variable over the last few model runs. -mcauley
fire weather... Updated 300 pm pdt Saturday 23 june 2018... The
thermal trough will retreat eastward on Sunday with temperatures
increasing about ten degrees across the region. Sunday will also
be 15 to possibly 20 degrees warmer than average. Daytime
humidities will fall to the mid and lower teens in valleys. Breezy
and much cooler conditions are expected Monday as a dry cold
front, except for some drizzle on the coast and coast range, moves
through. The strongest winds will occur east of the cascades
around Monday evening. -smith
