What forecasters said that day

The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Medford, OR wrote its last area forecast discussion before this small craft advisory went out at Jan 31, 3:17 PM PST, 4 hours 43 minutes earlier.

Area forecast discussion, Jan 31, 3:17 PM PST, 4 hours 43 minutes before
Area Forecast Discussion
National Weather Service Medford OR
317 PM PST Sun Jan 31 2021

.SHORT TERM...This afternoon through Tuesday...
A broad trough of low pressure off of the Pacific Northwest coast
continues to spin moisture into the area this afternoon. An
inland surge of precipitation today across the interior west side
to the Cascades is now re-configuring northwestward, orienting
more coastward with time. We've had reports up around 2 inches of
rain in 24 hours near O'Brien in Josephine County as of 3 PM PST.

Snow levels have risen across the forecast area to approximately
4500 feet this afternoon, though they might be as high as 5500
feet in some areas. This includes in the Mount Shasta area, where
precipitation has come to an end for now in Mount Shasta City and
on Snowman's Summit.

As the precipitation refocuses along and near the coast tonight
through Monday morning the main focus will be heavy rainfall
along and near the coast and winds out ahead of it. Please note
that the Areal Flood Watch remains in effect across much of
western Siskiyou, Josephine, Coos, and Curry counties through
4 AM PST Tuesday morning. We've had some reports of ponding water
beginning in some areas of Josephine County, but no flood reports
as of the writing of this discussion.

The South Fork of the Coquille River at Myrtle Point and Powers
are expected to reach Action Stage later Monday into Monday night,
with Minor Flood Stage expected at the Myrtle Point.
Additionally, the Coquille at Coquille is expected to go to action
stage early Tuesday. We will continue to closely watch the Chetco
River, but, as of now, only significant rises are expected on it
and action stage is not expected to be reached.

Monday afternoon and evening the frontal boundary is expected to
move eastward along with the heavy precipitation with it. Snow
levels will initially be in the 4500 to 5500 foot range as it
arrives, but then are likely to lower into the 3,000 to 4,000 foot
range as it moves through. Guidance still has a wide range of snow
levels as the front moves through, but went with the NAM12 to a
bit lower as the heaviest precipitation with the front moves
through. In short, we expect a period of moderate to very heavy
snowfall as the front moves through, heaviest in the Mount Shasta
area and mountains of Siskiyou County, and less heavy in the
Oregon Cascades. Expect that there's likely to be a period of
moderate to significant road impacts on I-5 later Monday
afternoon into the evening as the front moves through. ~BTL

.LONG TERM...Tuesday night through Sunday night...The beginning
portion of the long term bears watching for future updates.

The weather story  for Tuesday night through Wednesday has gotten
more interesting, with a now higher confidence that high
temperatures on Wednesday will be the coldest of the week, and also
an increased probability of precipitation for Tuesday night through
Wednesday. The key questions with a lower degree of certainty at
this juncture are the snow level and precipitation amounts.

The snow level falls a blend of models and is forecast to fall from
3000 feet to around 2000 feet on Tuesday night, then rise back to
around 2500 with the heating of the day on Wednesday. Regarding
snowfall amounts, widespread amounts of a dusting to an inch are
forecast above 2500 feet, and 2 to 5 inches in the southern Oregon
Cascades. The 12Z ECMWF leans toward the stronger/wetter/colder side
of the range of solutions and is focused upon late Tuesday night and
Wednesday morning, the 12Z GFS toward the weaker/drier side, while
the 12Z ECMWF ensemble members are about evenly split between
impactful and non-impactful snowfall. Meantime, the 18Z GFS data has
very recently arrived. It has trended slower (with a focus upon day-
time Wednesday lingering into early Wednesday evening), but is
stronger than its previous run, and still weaker than the ECMWF.
Quite simply, uncertainty is higher than usual this near to an
event, higher than we would like it to be. The widest range in
potential impact relates to the 3 passes along I-5 between Grants
Pass and Canyonville. About an inch of snow is forecast there, but
there is a risk of several inches of snow and also a potential of no
snow/for the snow level to remain above these passes.

A couple of days ago, the bulk of model solutions were progressive
in exiting the upper trough from our area with a rapidly diminishing
probability and quantity of precipitation. Yesterday, the mean
ensemble solutions caught on to a slower and splitting pattern with
our area generally between the northern and southern branches, with
some meager risk of light showers above 3000 feet. Lo and behold,
with the passage of another day, confidence has grown in a continued
slowing of the upper level pattern, with a more stretched trough
from northeast (over western Canada) to southwest (farther offshore
of California). As such, this places our area in a location to be
affected by the next wave dropping southeast from Alaska in the cold
northern branch.

Ridging is still expected to strengthen over the eastern Pacific
later Wednesday night into Thursday for a break between
disturbances, but widespread valley stratus during the night and
morning hours. Models have nearly universally trended weaker with a
shortwave moving southeast down the front side of the ridge Thursday
night through Friday. As such, the probability of precipitation has
been lowered from the previous forecast. Also, the high temperature
forecast on Friday is likely to be tricky/dependant on the extent
and timing of clearing of valley stratus. The ridge is expected to
build inland Friday night through Saturday night. Model agreement
regarding a dry forecast during this period has increased. That
agreement diminishes for Day 7/Sunday, but the mean solution
suggests a weak wave weakening the ridge as it passes relatively
harmlessly north of our area with a slight cooling trend and
increase in high level or mid and high level cloud cover to
accompany another episode of night and morning valley stratus. -DW
