Synopsis for the southern oregon coastal waters..Strong north winds and choppy wind driven seas will continue across the area through tonight, peaking in the late afternoon and evening. Gales are expected south of gold beach with very steep seas. Winds and seas will exceed small craft criteria over most of the remainder of the area. Winds will diminish tonight into Sunday, but there will still be significant fresh swell over the waters and most of the area will remain hazardous to small craft.

area forecast discussion
national weather service medford or
824 am pdt Sat aug 17 2019

Short term An upper level ridge is centered offshore and a
surface thermal trough remains along the coast. Offshore east to
northeast winds are continuing over western mountains this
morning. This is bringing clear skies and dry conditions to the
area, except for some patchy stratus located north of north bend
along the coast and southwest of roseburg as well as stratus off
the coast.

Conditions today will generally be similar to yesterday with warm
and dry conditions over the area. Winds are expected to be
slightly lower than yesterday but will continue to be breezy
across much of the area, especially in the afternoon and evening.

Northerly winds will pick up along the coast by this afternoon and
become gusty. Across inland valleys, expect breezy north to
northwest winds to develop by late afternoon and continue into the
early evening.

On Sunday, models continue to show the surface thermal trough
weakening. So expect decreased northeast winds over the coastal
mountains. Across the coastal waters, northerly winds will
gradually decrease tonight into Sunday as well. With this pattern,
expect areas of stratus or fog to develop tonight and Sunday
morning along the coast north of CAPE blanco and possibly near
brookings. Coastal stratus and fog will clear in the afternoon on
Sunday then return Sunday night. Inland, expect continued warm
and dry conditions on Sunday. Breezy to gusty west to southwest
winds are expected east of the cascades late Sunday afternoon and
Sunday evening.

Aviation For the 17 12z tafs... At the coast and just
offshore...VFR conditions will continue into this evening. Marine
stratus has developed north of koth and in portions of the umpqua
valley southwest of krbg, and it's lingering over the coastal
waters. Our latest forecast calls for only a couple hours of MVFR
ceilings at koth this morning, but confidence is low to moderate
on this. Confidence is higher on stratus moving in this evening.

Elsewhere,VFR conditions will continue through the TAF period. -

Marine Updated 200 am pdt Saturday 17 august 2019... A strong
thermal trough pattern will continue through this evening, then
slowly weaken Sunday. This will produce strong north winds and
choppy wind driven seas across the area, peaking late this afternoon
and evening. Gales and very steep seas are expected south of gold
beach. Winds and seas will exceed small craft criteria over most of
the remainder of the area. The winds will diminish into Sunday, but
there will still be significant fresh northwest swell over the
waters and most of the area will remain hazardous to small craft.

Seas will subside further into Monday. Winds and seas should be
below small craft advisory levels Monday morning through Tuesday.

From Wednesday into Thursday a mixture of two strong swells may
bring conditions hazardous to small craft back for much of the area.

Prev discussion issued 512 am pdt Sat aug 17 2019
updated aviation discussion.

Discussion... The 2 am satellite imagery is showing a small patch
of stratus dotting northern curry county and southern coos county
with stratus offshore. The remainder of southern oregon and
northern california are experiencing clear skies. This is
indicative to the area of high pressure dominating our area. This
combined with the thermal trough which will produce another warm
day across the area.

The main difference between yesterday and today is that winds are
expected be slightly less today. That being said, we will remain
warm and dry; with moderate humidity recoveries this morning over
the coast range and western siskiyou county. The thermal trough
weakens on Sunday so expect winds to decrease at the coast, and
thus temperatures to also to become closer to normal for this time
of year beginning Sunday.

For the rest of the area, expect temperatures in the upper 80s to
mid 90s for the inland valleys across southern oregon and northern
california all the way through next week. Otherwise, not expecting
any real impacts from the weather.

For the extended forecast, although models are coming into better
agreement that a front will come through associated with a low
digging down from british columbia, don't expect much of a pattern
change with it. Fully believe that the models will end up washing
this frontal boundary and low out like it did with the one that
was supposed to move across southern oregon yesterday (Friday).

Have continued to go with the calibrated ensemble which indicates
the continued dry and warm weather, albeit with a slight drop in
temperature than the mid to upper 90s for the west side valleys
and mid 80s for the east side valleys expected Tuesday and
Wednesday. -schaaf
fire weather... Updated 200 am pdt Saturday 7 august 2019... Warm and
dry conditions are expected across the area for the next several
days. The main concern is for east winds to continue over much of
curry, josephine, and western siskiyou counties this morning.

Recoveries in these areas will suffer, especially compared to the
higher values seen lately, and some of the more wind-prone and
exposed ridges could see strong wind gusts. An inversion just
above some of the higher peaks and ridges has the potential to
lower briefly at times overnight. If this happens, humidities
could quickly drop and winds would peak, but again, only for a
short time.

Elsewhere, temperatures will remain stable through Monday before
becoming a bit hotter by Tuesday into Friday.

Confidence in the long term forecast remains low, but models are
showing a distinct trend towards continuing dry and warm conditions
for next week, with above normal temperatures resulting from a
building ridge aloft. There are a few indications that a weak
impulse could pass through the region producing an increased risk
for thunder, but these should stay well to the north, and are only
expected to bring another modest cool down next weekend. -schaaf bpn
