Area Forecast Discussion
National Weather Service Medford OR
842 PM PST Mon Feb 1 2021

.DISCUSSION...A frontal system that's affected the forecast area for the
past several days continues to do so tonight, spreading
precipitation across the forecast area overnight. 2 to 6 inches of
rainfall has fallen in western portions of the forecast area,
generally west of Interstate 5. This, in combination with higher
snow levels, has helped melt snowpack in that area, bringing
increased runoff and resulting in significant river rises and some
landslides in Western Siskiyou County and in Coos County that
we're aware of. A Flood Watch for the Coquille River continues
through tomorrow evening while an Urban and Small Stream Flood
Advisory continues for Western Siskiyou, Josephine, Curry, and
Coos Counties, focused primarily on the "small stream" aspect.
Streams in those areas at this hour are running in the top 10
percent in terms of streamflow for this time of year. This
Advisory continues through tonight. Rain rates/coverage should
diminish after that point. Another aspect of this front over the
past several days has been wind. Widespread gusts 40 to 60 mph
have been observed at the coast, in the high terrain, in the Rogue
and Shasta Valleys, and east of the Cascades. Winds will continue
to diminish through tonight but will remain breezy Tuesday as
another low pressure approaches from the north Tuesday night into
Wednesday. It looks like today's winds will be the last strong
southerly flow event for the next week or so as deep flow turns
westerly Tuesday and eventually northerly later this week. Snow
continues as well with this front, with snow levels now at 4000
feet per recent webcams showing snow at Siskiyou Summit on
Interstate 5. Snow tonight into Tuesday morning will be focused
over the Cascades, Siskiyous, and the Mount Shasta region. Snow
levels will continue to lower through the overnight hours with
snow generally diminishing through the day Tuesday.

Our attention then turns to the next low, and the dayshift increased
messaging for the potential for widespread snowfall Wednesday. The
airmass behind the front tonight cools significantly, and the low's
trajectory, north to south along the Oregon coastline on Tuesday, is
one that favors snow down to at least 2000 feet. It will be
significantly colder than the current system where snow levels
bumped up to 5000 feet. So, prepared for wintry travel conditions at
mountain passes as early as Tuesday night, and potentially over
lower passes like Sexton/Canyon Creek on Interstate 5/Hayes Hill on
Highway 199. Right now per the latest data and historical valley snow
patterns the air mass doesn't look quite cold enough to bring
snow to valley floors of the Rogue/Illinois/Applegate Valleys but
it's not too far from it, so it's within the realm of possibility.
Please stay tuned to the forecast as we fine-tune the snow levels
and snow amounts over the next 24 hours. Right now, snow totals
from this low are expected to be 2 to 4 inches in the lower
elevations (2000 to 3000 ft) and 5 to 10 inches above those
elevations. This will be a relatively quick moving system compared
to recent fronts that have stalled in the region, resulting in
about a 12 hour period of snowfall.

Please see the previous discussion for more details on the upcoming
system and the extended forecast.

&&

.AVIATION...For the 02/00Z TAFs...MVFR/IFR conditions and
precipitation have spread to areas along and west of the Cascades
this afternoon, and will gradually move east through tonight. Expect
gusty south winds, widespread terrain obscuration, and snow above
4000 feet as this front moves through, with areas of low level wind
shear and mountain wave turbulence possible.

Once the front passes, winds should diminish, but showers are likely
to continue for several more hours before precipitation fully comes
to an end. Flight conditions should improve, but any clearing skies
over area valleys will likely result in the formation of IFR
conditions in fog and/or low stratus. Areas that do see greatly
reduced flight conditions should improve by late morning. -BPN

&&

.MARINE...Updated 800 PM PST Monday 1 Feb 2021...Winds and seas
will subside tonight into Tuesday morning, but by Tuesday afternoon,
winds and seas will increase again as the next front begins to make
its way through the coastal waters. The front will move onshore
Tuesday night, and while winds and seas are expected to generally
remain in the small craft advisory level, gale force gusts are
possible north of Cape Blanco. Offshore high pressure will build
Wednesday along with a trough near the coast. This will produce
gusty north winds and steep seas across the area, especially south
of Cape Blanco. This pattern will persist into early next week.

.PREV DISCUSSION... /Issued 359 PM PST Mon Feb 1 2021/

SHORT TERM...Tonight through Wednesday...The short term is mostly
a tale of two storms. The first storm will have its main impacts
continuing through this evening, till around midnight, with
additional lighter showers and snow showers through Tuesday
morning. Winter weather headlines have also been issued for a
colder system affecting the area late Tuesday night through
Wednesday afternoon.

High winds likely peaked earlier this afternoon from the Cascades
westward, and peaking right about now on the east side. But,
winds will remain nearly as strong on the east side this evening
before tapering off. A gust of 59 mph was reported at Weed, in
the southern Shasta Valley with high winds also over the higher
terrain.

Snowfall this evening will be heaviest over the higher terrain of
western and southern Siskiyou County, above 4000 feet. There is
also the expectation for lighter though still impactful snow at
elevations between 3000 and 4000 feet in southern Siskiyou County,
and much of the area with elevation above 4000 feet in southern
Oregon. East side snow amounts will be largely up to 3 inches.

Showers and snow showers will be light and isolated to scattered
during Tuesday afternoon and evening with one shortwave exiting
Lake and Modoc counties during the afternoon while the next
disturbance reaches the coastal counties. It will continue inland
with a modest uptick in shower activity expected in the evening in
southwest Oregon and snow levels around 3000 feet.

A cold front will follow late Tuesday night through Wednesday
with snow levels falling to around 2000 feet. Precipitation will
begin late evening and taper off during Wednesday afternoon, but
the bulk of precipitation will occur from around midnight to noon.
Though increased confidence has warranted issuing a Winter Weather
Advisory for a wide swath of the west side, for the Cascades, and
northern Klamath County, there is still moderate uncertainty in
the exact snow level, with a model mean solution that the snow
level will be around 2000 feet. Periods of higher intensity
precipitation and topographical effects could lead to snow at a
lower elevation at times, down to 1500 feet. On the other hand,
relatively warm temperatures at low elevations of the west side
ahead of this system will likely delay or prevent accumulation of
snow. Southwest winds associated with this storm will likely
reach advisory strength on the east side with gusts of 30 to 50
mph late Tuesday night into Wednesday morning.

LONG TERM...From Wednesday Night to Monday Night...Exiting a
very active period of weather around the region a building ridge
will bring an end to this activeness. By stabilizing conditions,
the possibility for fog/freezing fog enters the forecast Thursday
and Friday morning. Fog is currently forecast only for valleys
west of the Cascades and is not currently expected to be very
expansive. The Umpqua and Rogue valley, especially near Grants
Pass, are most likely to have the largest area of fog.

A weak front will break up as it approaches the coast early friday
morning. This may bring trace amounts of rain to some ridges around
Douglas County and increased cloud cover from Cape Blanco and the
Umpqua divide north, and along the Cascades. The increase of mid-to-
upper level cloud cover could cause the fog to erode more quickly
or fail to form all together Friday morning for areas north of the
Umpqua divide. Winds may also become elevated and slightly breezy
along and east of the Cascades, but the extent of these winds mostly
depends on just how intact the upper level portion of the front
remains as it moves through.

Upstream of the ridge, in the central Pacific and over Siberia, the
pattern should remaining active. Lows will continue to batter the
western portion of the ridge, narrowing and shortening it. This will
eventually lead to northwest flow and the opportunity for a
shortwave or two embedded in that flow to move through the PNW. There
are still significant timing differences in the GEFS and EC
ensembles, but the impact is expected to relatively low. The
ensemble means are in fairly good agreement that a shortwave will
eventually bring a front through our area shortly after Monday
night. The impacts for now can be summarized as light rain along the
coast and high terrain, and even lighter amounts of snow. The NBM
has snow levels in the 3000-3500 feet range, with some diurnal
variation due to the colder NW flow. During this time, the ridge
over the region retrogrades into the Central Pacific and blocks more
progressive lows from entering the region.
