.DISCUSSION...The past 24 hour rainfall totals as of midnight
showed that the most rainfall fell west of the Cascades with
totals reaching 0.30"-0.75". Medford was an area that saw near
the 0.75" mark! Western Siskiyou County also saw similar amounts
and areas east of the Cascades had around 0.10". Now that things
are drying out, temperatures will fall to the 40s near the coast
and 30s inland with 20s in northern Lake and Klamath counties.
These will be the typical morning temperatures through Friday.
Low stratus is building across parts of Douglas, Josephine and
Jackson counties and on the east side tonight, and there could also
be fog early this morning. This will burn later in the morning, and
afternoon temperatures will get a bump to near normal in more spots.
This means more 60s for west side and 50s east, and we can expect
the same for the next several days. This afternoon and overnight the
upper trough that brought all of our rain will be to our south and
move east. During this time the eastern corners of Modoc and Lake
counties could see a few rain showers with less than a tenth of
an inch forecast. Snow levels will be around 7,000`, so the
Warners could see a few snow showers with minimal accumulations
expected.
Ridging builds at the start of the weekend and near to slightly
above normal temperatures are forecast Saturday. Enjoy it while it
lasts because the next day a trough moves in and brings rain chances
with cooler temperatures once again. Snow levels during that time
are forecast to fall to 5,000`-5,500` once again. There is agreement
that the precipitation could continue through at least Sunday
afternoon. Shower activity could linger into Tuesday before the
upper trough moves east. Drier conditions could return later
Tuesday, and the EC has stronger signals that an Omega Block could
be present that would keep those dry conditions around. This will
be monitored, but for now the highest confidence lies that Sunday
will see the start of the return of precipitation.

.AVIATION...14/12Z TAFs...Surface moisture and cool temperatures are
allowing for fog to develop in low-lying areas early this morning.
Satellite shows low clouds over the Rogue and Umpqua Valley, so
looking for these conditions to turn to IFR in the coming hours.
MVFR to IFR conditions are present along the coast, although it is
intermittent at North Bend. Chances look lower for the Klamath Basin
as breezy conditions persist into the night, although a brief period
of lower ceilings and visibilities is possible if winds ease. Any
overnight development looks to clear out before this afternoon.
VFR levels are expected across most of the area by this evening.
Showers are possible over Modoc County and adjacent areas this
afternoon and evening. -TAD

.MARINE...Updated 230 AM PDT Tuesday, October 14, 2025...Seas will
remain steep to very steep today, highest over the outer waters.
Lighter winds and lower seas will return Wednesday into Thursday
morning. North winds increase Thursday afternoon into Friday with
possible small craft advisory level conditions again south of Cape
Blanco. Long period swell could arrive Friday. -Spilde

.BEACH HAZARDS...Updated 230 AM PDT Tuesday, October 14,
2025...We`re heading into the time of year where distant storms
generate swells with long periods. These long-period swells harbor
more energy than a typical set of waves and have the ability to run
up much farther on the beaches. Model guidance is showing a long-
period swell (7-9 ft at ~17-19 seconds) arriving later this week,
probably sometime Friday and lasting into Saturday before decaying.
This could pose a threat for sneaker waves at area beaches. We call
them "sneaker waves" because they aren`t particularly large or even
high waves, but because they exhibit such high energy, they can
suddenly wash over rocks, logs and jetties without much warning.
We`ll be evaluating this potential and a beach hazards statement may
be necessary at some point. -Spilde
