Area Forecast Discussion
National Weather Service Medford OR
301 PM PDT Wed Oct 18 2017

.SHORT TERM...Models remain on track showing a strong incoming
front approaching the area late tonight and moving inland tomorrow.
This is followed by a colder pattern with showers and mountain
snow on Friday.

The impacts expected from the incoming storm include:

*Rain Impacts: Ponding on roadways, debris flows or mud slides
 possible near recent burn scars near the Curry coast and in
 western Siskiyou County tomorrow.
*Wind Impacts: Travel may become difficult for high profile
 vehicles tomorrow due to strong southerly winds along the
 coastal headlands, Shasta Valley, and east of the Cascades.
*Isolated trees may fall near burn scars due to high winds.
*Dangerous conditions for beach goers with high surf conditions
 along the coast late Thursday afternoon through Friday.
*Dangerous seas developing in the coastal waters tonight through
 tomorrow then continuing into Friday. Strong gale force winds
 will accompany these seas tonight and tomorrow morning.
*Snow Impacts: Slippery, snow-covered roads over the higher
 passes in the Cascades near Crater Lake and Diamond Lake on
 Friday. Light snow on highway 140 near Lake of the Woods on
 Friday.

As the front approaches the region, light rain will develop late
tonight along the coast with moderate to heavy rain expected
tomorrow for coastal areas. Rainfall will peak at the coast
tomorrow afternoon into early tomorrow evening. Inland areas are
expected to see rain spread across the area Thursday afternoon and
evening as the front pushes inland. Rain will be moderate to
heavy from the coastal mountains to the Southern Oregon Cascades
as well as in western Siskiyous County. Elsewhere expect light to
moderate rain. Heavy rain over recent burn scars in Curry, extreme
western Josephine and extreme western Siskiyou county will bring
the potential for rock or mud slides which may impact area roads
near these burn scars. A flash flood watch is in effect for these
areas. Please see the FFAMFR for details.

As the front approaches the region tonight, expect south winds to
increase over the ridges, along the coast and over the coastal
waters. Winds will peak at the coast tomorrow morning and expect
wind gusts in the 30 to 45 mph range along the coast with higher
gusts up to 60 mph at Cape Blanco. Winds will increase over inland
areas tomorrow afternoon and evening, when a strong mid level jet
is forecast to move into the area. Although most all areas will
see gusty winds, the strongest winds are expected in areas east of
the Cascades, in the southern Shasta Valley as well as over the
higher mountains. South winds are expected to gust to around 40 to
50 mph in many valleys east of the Cascades and in the southern
Shasta Valley on Thursday with higher gusts of 60 mph possible in
portions of Lake County and over the Warner Mountains in eastern
Modoc county. Of note, these strong winds over eastern areas will
develop in advance of the precipitation Thursday afternoon with
rain moving into the Shasta Valley and areas east of the Cascades
late Thursday afternoon into Thursday evening.These winds will
lower Thursday night behind the frontal passage. A high wind
warning and wind advisory is in effect for these areas. Please see
the NPWMFR for details.

Also of concern behind the front, expect a large northwest swell
to reach the coast. This will bring large wave run ups on the
beach and dangerous high surf conditions. A high surf advisory is
in effect for the Southern Oregon coast Thursday evening into
Friday. Please see the CFWMFR for details.

Behind this front widespread to numerous showers are expected
tomorrow night into Friday along with snow levels lowering to 4000
to 5000 feet. This will bring light to moderate snow to the
passes in the Cascades Thursday night through Friday afternoon.
Around 4 to 7 inches of snow is expected in the Diamond Lake and
Crater Lake areas with around 3 inches near Lake of the Woods.
However, relatively warm road temperatures may limit the amount of
snow that accumulates on roadways during this period. The peak
snowfall is expected tomorrow night through Friday morning. Snow
showers are possible during the afternoon on Friday but
accumulations are expected to be light except for over higher
locations such as near Crater Lake.

Expect only a brief break in the active pattern Friday evening
then a strong and moist warm front will spread precipitation into
the area Friday night and Saturday. This next front  will bring
moderate rain from the Cascades west with light to moderate
precipitation east of the Cascades and in Northern California.
Snow levels are expected to rise to above pass levels on Saturday
as this front moves inland. Another period of strong or gusty winds
is possible with this warm front on Saturday. The strong winds
will be mainly over the mountains, although gusty winds are
likely over much of the area on Saturday.

.LONG TERM...Monday 23 Oct through Wednesday 26
Oct 2017...A strong ridge will build in at the beginning of the
period, and any remaining showers will dissipate during the day
Monday.  Low level easterly flow will develop Monday night, drying
out the air mass further. The offshore low level flow will continue
through Tuesday night. After that the medium range model forecasts
diverge. The GFS weakens the thermal trough near the coast and
brings a weak front into the offshore waters Thursday morning.
Meanwhile, the EC hangs on to a strong trough with offshore flow
continuing into Thursday.  Will go with dry forecast through
Wednesday night before ramping up the POPs offshore Wednesday night.
Will keep any precipitation well offshore through Wednesday night.

&&

.AVIATION...18/12Z TAF Cycle...In the coastal waters MVFR conditions
are widespread right up to the coast down to Port Cape Blanco.
Orford. Expect little change in coverage throughout the day. From
Port Orford south MVFR conditions are farther offshore beyond 10nm
from shore. Inland, low clouds and MVFR cigs extends into NW Douglas
County. IFR conditions at RBG appear to be isolated event and do not
show up on satellite imagery. RBG should improve to VFR by 18Z at
the latest. Elsewhere, VFR is expected.

The next front will bring more clouds to the area. Aside from the
coast, conditions inland are expected to remain VFR until late
tonight with local MVFR inland. /FB

&&

.MARINE...Updated 230 PM PDT Wednesday 18 October 2017...South winds
will increase today across the waters ahead of a strong cold front.
Confidence is high for gales from Cape Blanco northward tonight with
warning level seas most places.

Long period and large northwest swells (around 20 feet at 17
seconds) build into the waters late Thursday into Friday behind the
front, creating dangerous surf and bar conditions. The tail end of
the cold front is expected to move back northward as a warm front,
and winds are expected to increase again Friday night and Saturday
with guidance showing Gale Force Winds again. /FB

&&

.HYDROLOGY...Updated 400 PM PDT Tuesday 17 October 2017... There
will be some hydrologic concerns with the Wednesday night into
Friday system. Currently, soils are dry and rivers are low, but
there will be enough rain to create possible debris flows near
recent burn scars. The river levels will not be an issue itself,
but the debris may obstruct river flows at times, creating
elevated river levels upstream of the block at first, then
downstream of the block if and when it breaks free. If you come
across a flooded road, find an alternate route. Remember to turn
around, don't drown.

Debris floating down the river combined with high surf may create
dangerous bar conditions near the Port of Brookings. -Schaaf
