Area Forecast Discussion
National Weather Service Medford OR
238 AM PST Fri Feb 10 2023

.DISCUSSION...A front has stalled across the area this morning,
with the associated upper level trough splitting as it moved
onshore. The northern portion of the trough will continue to
slowly progress east over Washington today, while the southern
portions closes off and digs south into California. As a result,
shower activity will linger over the area today into tonight, as
the trough pivots and upper level energy passes just to our
southwest. The increased cloud cover and colder air mass will
cause temperatures today to be much closer to normal for February.
Showers will gradually taper off and shift to the east through
tonight, with high pressure rebuilding and drying the area out by
Saturday afternoon.

High pressure will remain in place through the weekend.
Temperatures will be slow to rebound with near normal temperatures
expected on Saturday morning for inland areas and chilly
temperatures below normal at the coast. Saturday night will be a
little bit colder as the clouds clear, only a few degrees below
normal everywhere (the most dramatic difference to normal will be
at the coast).

The next system arrives in two steps, the first Monday morning,
followed by the second Monday night into Tuesday morning. The
first shortwave will arrive from the northwest Monday morning,
producing very light precipitation at the coast and over areas
along and north of the Umpqua Divide, as well as for the Cascades
north of Crater Lake. Expect snow levels between 5000 at 6000
feet along and west of the Cascades and between 4000 and 5000 feet
east of the Cascades. While this first round will not bring
significant impacts to the area, it will break down and displace
the ridge of high pressure from our area, and introduce much
colder air into the region.

The second, much more impactful wave, arrives late Monday.
Conditions are lining up into what is looking more and more to be
a decent low-elevation snow event. The overall flow accompanying
this system will originate from a more westerly direction,
enhancing precipitation along western slopes, and diminishing the
downsloping effects typically seen in many of the West Side
valleys. Temperatures will drop sharply Monday, and snow levels
are forecast to lower to 750 to 1000 feet Monday night into Tuesday
morning. The result will be accumulating snowfall for almost the
entire area, with the exception of areas west of the coastal
ranges. Winter weather impacts are expected Monday night into
Tuesday morning, and with showers lingering due to onshore flow,
impacts may very well continue throughout the day Tuesday, with
all area passes, and nearly the entire Interstate 5 corridor at
risk of travel issues. Confidence is increasing with this event,
as models have depicted this scenario for several days now, and
throughout that time, have also increased snow amounts and lowered
snow levels with each model cycle. Stay tuned for more updates as
models better resolve the details of this system over the weekend.

Ridging then return Wednesday, with dry conditions expected to
continue through the remainder of the week. A deep and broad
Hudson low will slow the progression in the upper levels, keeping
a broad ridge in place over the West Coast for the remainder of
the forecast term. -BPN

&&

.AVIATION...10/06Z TAFs...A front will stall near the Cascades and
extend back to an area of low pressure developing offshore tonight.
Areas of MVFR with light rain and partial obscuration of higher
terrain can be expected along the coast and inland over the west
side, but mainly north and west of Medford. VFR will prevail
elsewhere.

The low will move toward NorCal on Friday. Scattered to occasionally
BKN VFR ceilings are expected at Medford through Friday afternoon
(00Z Sat) and over the East Side, including Klamath Falls, through
03z Sat. With the low cutting to the south Friday night, expect a
mix of VFR/MVFR with areas of light rain and higher terrain
obscurations. Most TAF sites will have at least a period of MVFR
with some light rain showers. But, the best chance for low ceilings
and precipitation is in NorCal. -Spilde

&&

.MARINE...Updated 210 AM PST Friday, February 10, 2023...A front is
moving onshore currently. Southerly winds will ease behind the front
with seas transitioning to swell dominated this morning as another
steep west swell arrives. Low pressure offshore will pass south of
the waters today, eventually moving into northern California
tonight. Strong north winds will develop behind it and persist
through Saturday. This should bring a very brief period of gales
with lingering very steep and hazardous seas south of Gold Beach
Saturday afternoon into Sunday. Additionally, another long period
swell is anticipated to build into the waters late Sunday into
Monday, peaking on Tuesday potentially as high as 19 ft. As such,
hazardous conditions are likely to continue through the weekend and
well into next week. -Sven

&&

.BEACH HAZARDS...Updated 215 AM Friday, Feb 10, 2023...Models
continue steady showing a combination of a building long period
swell, and rising tide will bring a moderate chance of sneaker waves
Sunday. A beach hazard statement has been issued for this event. the
westerly swell continues to build into Monday afternoon, with surf
heights up to 25 feet possible. -Sven
