Area Forecast Discussion
National Weather Service Medford OR
837 PM PST Wed Nov 11 2020

.UPDATE...Clear skies will be the rule tonight, but with every
rule, there is an exception. In this case, it will be the West
Side Valleys, where fog and low stratus have already started to
form, particularly in the Coquille and other coastal valleys, as
well as in the lower portions of the Umpqua Basin. These areas of
fog should fill in most of the valleys overnight, with clearing
expected tomorrow morning as winds increase ahead of the upcoming
weekend systems.

Major forecast efforts will continue to focus on those weekend
fronts, as well as the active pattern that is expected to
continue well into next week, and perhaps beyond. For more
information on the forecast, and the wind and winter weather
products, see the previous discussion below. -BPN

&&

.AVIATION...For the 12/00Z TAFS...VFR conditions will prevail into
Thursday morning, except for areas of late night through early
morning IFR cigs/vsbys in low clouds and fog/freezing fog over
the west side valleys.  Areas of MVFR cigs in low clouds and rain
will develop over the coastal waters late Thursday morning, moving
into the coast Thursday afternoon and inland to the Coast Range and
Umpqua Basin late Thursday afternoon and evening with higher
terrain becoming obscured.

&&

.MARINE...Updated 200 PM PST Wednesday 11 Nov 2020...Steep northwest
swell will subside by this evening. A front will move onshore
Thursday followed by a very strong front Friday. This second
front will bring gale force south winds to the area, along with
very steep and heavy seas. Winds will reach storm force along the
coast from around Cape Blanco north.

After the front moves inland, very heavy northwest swell will move
in, bring 20 to 30 foot seas to the area Friday night into Saturday.
This will generate high surf along the coast as well.

The active pattern will continue into next week as several more
fronts move onshore, but none are forecast to be as strong as the
Friday front.

&&

.PREV DISCUSSION... /Issued 306 PM PST Wed Nov 11 2020/

SHORT TERM...There is brief break in the active weather today
with mostly sunny skies and mild conditions this afternoon.  Then
the next front will move towards the area Thursday. Another much
stronger and moister front will then impact the area Friday
morning through early Saturday morning. This second front will
likely bring widespread moderate to heavy precipitation and heavy
snow to higher terrain in the Southern Oregon Cascades, east side
and Mount Shasta area. Gusty winds are likely across all areas
on Friday with strongest winds in the mountains. Warning levels
winds are possible at the coast and inland across the higher
terrain east of the Cascades and in the Summer Lake area.

On Thursday, light to locally moderate precipitation will spread
inland along the coast, into Umpqua Basin and into the Southern
Oregon Cascades beginning Thursday afternoon and continue through
Thursday night. Other areas south of the Umpqua divide and east of
the Cascades will see chances for light precipitation Thursday
evening and night. Snow levels will be around 4000 feet, and
locally down to 3500 feet elevation, as precipitation spreads
inland. So expect light snow accumulations in the Southern Oregon
Cascades with up to 2 inches from Lake of the Woods south and 2
to 4 inches north of Lake of the Woods. Models indicate this front
will stall over northwest portions of the area Thursday night
until the next front arrives on Friday.

On Friday, models are indicating that a strengthening low pressure
center will move into the Washington coast and bring a strong
front into the region. This system has strong upper level support
with a 140-160 kt upper level jet. Variability still remains in
the exact track and intensity of the low but overall models are
indicating a solution that would support high winds, heavy rain
and heavy mountain snow across portions of the area as this front
moves inland.

Precipitation: Current models indicate the heaviest precipitation
would affect the coast Friday morning and afternoon, followed by
lighter precipitation Friday evening and night. Storm total
rainfall along the coast and into the coastal mountains is
expected to be around 1.5 to 4 inches Friday morning through
Saturday morning. Inland areas are expected to see light to
moderate precipitation Friday morning, with moderate to locally
heavy precipitation developing Friday afternoon, then continuing
lighter precipitation continuing into Friday night. Rainfall
totals of 0.5 to 1.5 inches are expected in valleys west of the
Cascades, locally higher near Happy Camp and western Siskiyou.

With the heavier precipitation we will be watching rain rates
along wildfire burn scars west of the Cascades, especially for
the Slater burn scar and Archie Creek as well as the Red Salmon.
Models continue to indicate there is a low risk for flash flood
or debris flow in these areas. However, we will continue to
monitor this. Heaviest precipitation on Friday is expected to
affect these areas late Friday morning through Friday afternoon.
Those near area burn scars, and particularly the Slater and Archie
Creek areas, should stay tuned to the forecast and be alert for
weather changes.

Snow: Based on current models, there is moderate to high
confidence for heavy wet snow and strong wind in the Southern
Oregon Cascades and for higher terrain east of the Cascades.
Models indicate snow levels around 5000 to 5500 feet Friday,
lowering to 4000 feet Friday night and locally down to 3500 feet.
Snow accumulations of 10 to 24 inches are possible in the Southern
Oregon Cascades Friday morning through early Saturday morning
with 6 to 10 inches across the higher terrain above 5000 ft
elevation east of the Cascades. Heavy snow combined with high
winds may bring periods of near white out conditions and
significant tree damage, especially in the Cascades. Winter storm
watches remain in effect for the Southern Oregon Cascades and
higher terrain east of the Cascades.  Further south in the Mount
Shasta area, snow levels are expected to start out lower, around
3500 to 4000 feet then gradually rise to 4500 feet as the heavier
precipitation moves into the area on Friday. There is goods
southerly upslope flow into the area during the late morning
through early evening on Friday. This will bring the potential for
heavy snow above 4000 feet in the Mount Shasta areas. A winter
storm watch has been issued for this area. Please see the WSWMFR for
details.

Winds: As the front moves onshore, models indicate that a strong
70 kt low level jet will move into the coast.  This strong low
level jet and a strong surface pressure gradient (10-11 mb from
Arcata to North bend) will bring the potential for high winds
along the coast north of Gold Beach Friday morning and afternoon.
Inland areas will see widespread gusty winds develop Friday into
Friday evening. Models on track, indicating a 60 to 90 kt 700 mb
jet moving into the area, strongest across Southwest Oregon. Very
strong and damaging winds are possible across the higher
mountains, especially from the Cascades eastward. Gusts up to 75
mph are possible across the higher terrain in eastern Klamath and
Lake Counties as well as highway 31 between Paisley and Silver
Lake in Lake County. Please see the NPWMFR for details. Also very
strong winds may affect exposed areas in the Cascades. This
combined with heavy snow will bring increased danger of tree
damage and white out conditions. Other areas may see advisory
level winds with gusts to around 45 to 55 mph, including in the
Shasta Valley and for valleys east of the Cascades. Winds are
expected to peak late Friday morning through early Friday evening
for most inland areas.

As the upper trough and front shift east, precipitation will be
gradually ease Friday night into Saturday morning. However ongoing
showers are expected. Winds will trend lower Friday night into
Saturday morning.

LONG TERM...(Saturday morning through Tuesday)...The trough begins to
flatten out as heavy shower activity decreases. Lighter
precipitation will linger through the day and snow levels will drop
on Saturday to around 4000 feet, producing light amounts of
accumulating snow from the Cascades east, and across Siskiyou
County. Winds will also begin to ease from the Cascades east,
although Saturday morning will still be windy across all of Lake
County.

Model trends indicate that a ridge will build in strong enough to
limit rain potential for locations east of the Coast Range on
Monday. This stronger ridge solution has increased from 21% of
total members to 23%, with an additional 15% (up from 11%
yesterday) of members showing a similar, but slightly weaker ridge
pattern in the WPC clusters. Individual member rainfall totals
have steadily decreased with each run for this time period, so
made edits to lower PoPs east of the Coast Range, zero out QPF in
east side valleys, and lower west side valley QPF to a few
hundredths. If this trend continues expect further lowering.

Another low will track towards the Oregon coast after Tuesday
morning. So far the leading solution is for the low to remain weaker
than the one moving onshore this Friday. This will keep winds light
in the valleys, though ridges from the coast range to the Cascades
and the east side are likely to experience gusty winds. The ridge is
also showing signs of further strengthening over the Rocky
mountains. This combined with a less deep low also indicates that
fronts from this low will struggle to advance beyond the Cascades.
Expect rain that does for to be terrain locked, while the heaviest
amounts stay isolated to the Coast Range.

One final note is that the low will be warmer than the low this
Friday and will be preceded by a day of warming. This will result
in less snow and more liquid precipitation, as early snow level
predictions are above 6000 feet with the first front. After nearly
a week of snow and rain, rivers will be on the rise. Though they
won't be near flood stage, they will still be higher than at any
time since spring. So, caution should be taken when around rivers
as their waters will be cold and underestimation of river current
strength may lead to serious injuries. -Miles
