Area Forecast Discussion
National Weather Service Medford OR
234 PM PST Sat Jan 13 2024
.DISCUSSION...Arctic air is resting just to the north of the forecast
area, causing some noteworthy temperature differences. The current
temperature at Roseburg is 51 degrees, while Eugene is at 26
degrees. Chemult is in the low 30s while Crescent (20 miles to the
north) is in single digits. Warm air from an approaching cutoff low
mixing with this arctic air in places has made observing snow levels
difficult today, to say the least.
Widespread precipitation will continue over northern California ans
southern Oregon this evening as that cutoff low makes landfall. West
of the Cascades, rainfall is most likely. Reports of small stream
flooding in Roseburg and in Eagle Point support Flood Advisories
focused on those urban areas through the early evening.
Rain and snow showers are continuing to move over areas east of the
Cascades. Snow levels have fluctuated through the day, with 3500 to
4500 feet being a good approximation. Strong winds over the Cascades
and farther east are expected to persist through the evening as
well, with the broadest areas of elevated winds across the southern
half of Lake County. A Winter Storm Warning is in place for areas
along and east of the Cascades to communicate the hazardous
combination of winds and winter precipitation.
An upper ridge building behind the current activity will bring
generally calmer conditions through Sunday. Scattered showers will
continue into Sunday morning but coverage will quickly decrease.
Diminishing (60%, falling to 30%) precipitation chances will remain
over the Oregon coast south of Cape Blanco, over the Cascades, and
over parts of Modoc County through Sunday afternoon. Temperatures in
the teens for east side areas and near or at freezing for inland
valleys may refreeze snowfall or accumulated water. Extra caution on
nonporous surfaces may be needed.
Monday looks to remain calm under the upper ridge, with active
weather expected to return by Tuesday afternoon. An upper trough
approaching from the southwest will bring another round of
precipitation. This midweek system won't have the same wintry
impacts as the one that affected the area today. The Oregon coast
south of Cape Blanco and western Siskiyou County are currently
forecast to get 1 to 2 inches of rain, while other west side areas
will get lower amounts. Snow accumulation looks to be limited to
the Cascades and higher terrain east of the Cascades, .
A weak ridge could help keep Thursday dry again. Current long-
term model guidance shows possible abundant activity on Friday
evening that could continue through next week. Both the ECMWF and
GFS graphical models show a low pressure system setting up south
of Alaska bringing multiple fronts to the area. Ensemble guidance
from both models suggests frequent precipitation through next
week for west side areas, with the highest amounts falling over
the Oregon coast. While forecasting for over a week out will not
come with an abundance of confidence in any specific outcome,
there is good agreement between these long-term models that active
weather will be continuing. -TAD

.AVIATION...13/18Z TAFs...Widespread precipitation will continue to
bring lower ceilings and visibilities through the day today. Current
snow levels of 7500 feet or higher west of the Cascades will keep
most precipitation as rainfall. Snowfall is reaching Klamath Falls
at 4000 feet, indicating a quick drop in snow levels past the
Cascades. These conditions are bringing widespread MVFR or IFR
conditions, with areas of LIFR conditions possible under heavy
precipitation. Please note that constant precipitation may locally
lower ceilings, visibilities, and snow levels as well as obscure
terrain.
Low level wind shear is also a concern through most of the TAF
period. Current guidance suggests that 40 knot winds from the
southwest are already present at 2000 feet over higher elevation
areas. Areal coverage will spread through the evening and move east
of the Cascades, with 50 to 60 knot winds possible over Lake County
and 40 to 50 knot winds over Klamath and Modoc counties into Sunday
morning. This east side shear will be at 1500 to 2000 feet.
Scattered showers will continue into Saturday morning and generally
remaining over higher terrain by the end of the TAF period. Low
ceilings and impaired visibility is possible under more a stable
atmospheric pattern, but will depend on remaining cloud cover and
surface conditions. -TAD

.MARINE...Updated 215 PM Saturday January 12, 2024...A strong low
pressure system remains offshore this afternoon. Southwest winds are
gusty across all waters currently with the potential for gale force
gusts through about 7 pm. The low will move onshore late this
evening resulting in a wind shift to northerly. Winds will ease to
around 10 to 20 kt. However, a high and very steep fresh swell will
accompany the low as it moves onshore and behind it, keeping seas
very hazardous into Sunday morning. Latest model guidance is showing
seas peaking at 12 to 18 ft at 11 or 12 seconds, highest over the
outer waters beyond 10 nm from shore, but still very steep over the
inner waters as well. We have extended the hazardous seas warning
through 10 am, then seas should eventually subside below 10 ft
Sunday afternoon. Improving conditions are expected into Monday,
then the next front will approach on Tuesday resulting in another
round of increasing south winds and steep seas. -Spilde
