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

Area Forecast Discussion
National Weather Service Medford OR
928 PM PDT Sat Nov 6 2021
.DISCUSSION...A reminder that we will fall back an hour overnight
with the change from PDT to PST.
An update has been issued to nudge expected precipitation and
snow amounts tonight a bit higher for the Umpqua Divide Region,
mainly from north of Prospect to Union Creek, Crater Lake, and
Diamond Lake. Snowfall of 1 to 3 inches is expected in that area
from earlier this evening through 4 AM PST on Sunday morning.
Snow levels are expected to bottom out around 3300 feet MSL.
The other area with the most numerous showers is expected to be
Curry County.
The next shortwave in this onshore flow pattern will bring
additional light showers, almost exclusively from the Oregon coast
to the southern Oregon Cascades during Sunday...with a few also
into far western Siskiyou County. This activity will linger
longest at the coast and gradually diminish later Sunday evening
into Monday morning. The coast will have about a 6-hour break of
dry weather Monday morning into early afternoon.
As the new suite of model data continues to filter in, the focus
for the next forecast issuance will be on a strong storm to affect
our area mainly Monday afternoon into early Tuesday morning.
A High Wind Watch remains in effect with the potential for gusts
to 60 mph for our usually windiest locales, the coast, the Shasta
Valley, and portions of the east side (including the Summer Lake
area and Warner Mountains). Though, perhaps not quite reaching
high wind criteria, Strong winds are also possible in the Rogue
Valley from Ashland to the south and east sections of Medford.
Snow levels with this storm will vary significantly with strong
upslope southerly flow bringing a 3500 to 4000 foot snow level in
the vicinity of Mount Shasta that rises to 4500 feet, while Cascade
and east side snow levels begin around 4000 feet and rise to 5500
feet. Meantime, snow levels farther west will rise well above the
higher terrain...around 7000 feet near Oregon Caves as precipitation
diminishes early Tuesday morning.
Please see the previous discussion below for further forecast details
farther out in time.

.AVIATION...07/00Z TAFs...A continued mix of VFR and MVFR cigs are
expected through the TAF period, with periods of showers and
mountain obscurations across the forecast area. During periods when
mid to high level clouds clear, there may also be some IFR cigs over
the west side valleys between 06-18z Sunday, with local IFR
visibility in patchy fog. Freezing levels should hover between 3000
and 4000 feet above sea level. -BPN/MTS
&&
.MARINE...Updated 800 PM PDT Saturday 6 November 2021...Low pressure
remains to the north through Sunday. A deep low pressure center will
approach from the west Monday and move inside of 130W off the
central Oregon coast by early Monday evening. Despite uncertainty in
the forecast models in the strength and timing of this low, it
appears likely to produce gales and hazardous seas over the outer
waters Monday night. Tuesday should see improving weather with
fairly low-end winds and seas from mid to late week. MTS

.PREV DISCUSSION... /Issued 308 PM PDT Sat Nov 6 2021/
SHORT TERM...
The radar scope is becoming a little more filled in the last hour
as a little moisture and another disturbance moves through. These
showers are also putting down some quick wetting rain. Grants Pass
saw 0.1 inches of rain over 10 to 15 minutes as a shower moved
overhead earlier this afternoon. In addition, a positive cloud to
ground strike was just observed off the Douglas County coast this
afternoon. Therefore, the slight chance of thunder seems very
appropriate into this evening and tonight along the coast. The
cold airmass aloft will keep the atmosphere rather unstable with
snow levels down to 3500 feet tonight. Snow accumulations from
this evening into tonight should be under 1 - 2 inches over the
mountains and higher elevations. Locations around 3500 feet should
see trace amounts of snow at most.
Heading into Sunday, the cool and unstable pattern remains and
showers will likely cover most locations along the coast and some
of the higher terrain along the Cascades. Rain Accumulation will
vary from trace amounts of rain up to 0.25 inches. Overall, no
impacts here as the unsettled weather and moisture persists over
the area.
By Sunday night into Monday, conditions will dry and clear briefly
as an upper level ridge builds in briefly overnight. We're
forecasting some frost in the valleys west and east of the
Cascades. This may require extra time added to ones commute to
clear off a windshield.
Conditions will begin to change through the day Monday as upper
level clouds build ahead of a well developed warm front. Another
low will begin to intensify out over the Pacific and southerly
winds will subsequently strengthen Monday evening along the coast
and eventually over locations farther to the east. Upper level
winds from 4500 to 9000 feet are quite strong in some of the
deterministic models. Because of this, we decided to keep the high
wind watch over many locations within our warning area. View the
high wind watch on our web page (weather.gov/medford) for more
details on hazards related to the high potential winds.
Aside from the wind, snow also remains a concern within northern
California specifically Monday night. As is typically with
systems which have strong southerly winds up the Sacramento
Valley, the Trinity Mountains and locations around Mt. Shasta
City have the potential to see some snow accumulation. The NBM has
lowered this threat recently as the probability of snow
accumulation greater than 4 inches is only 20 percent versus 40
percent yesterday. In addition, our official forecast has about 4
inches of snow along Black Butte Summit on I-5 with roughly 8 to
12 inches over the mountains in Siskiyou County. Overall, we kept
the winter storm watch going, although the chance for issuing a
warning has diminished based on the latest ensemble data. View
the winter storm watch on our web page (weather.gov/medford) for
more details on the hazard.
Once the front passes through late Monday night, snow levels will
rise from 3500 feet up to 5500 feet and the precipitation will
decrease into the day Tuesday.

LONG TERM...Wednesday through Saturday...The pattern does not
necessarily quiet down Wednesday into Thursday, as a weaker warm
front. Snow levels will be on the rise and thus snow concerns lower,
though the snow melt is likely to sustain flow in smaller creeks.
Friday and beyond, model guidance is hinting at potential ridge
amplification later next week, which would deflect the storm track
farther to the north and result in a period of drier, milder weather
here (albeit at the expense of low clouds/fog, and frost). The trend
is going towards less amplification, which would allow for the
southern end of decaying fronts to impinge on the coast. Some light
PoPs and precip were kept there, but generally places inland from
the coast range remain dry in the extended. A squashed ridge would
allow for more cloud cover though, which will modulate the amount of
fog and frost each morning.
