.DISCUSSION...
Showers continue this morning, with accumulations on area roadways
mainly above 2500 feet. Snow levels continue to fall, already
down to 1500 feet at Camas Mountain and in the Scott Valley.
The large trough of low pressure over the Northwest this morning
is still centered offshore. The coldest air aloft at 500mb will
push inland today and tonight from the northwest with -36C to -38C
at that level. As is usually the situation with a showery regime,
pinning down precipitation timing and amounts to 6 hour time
steps is difficult, but the overall result over the next 24 hours
is generally known. Snow levels will likely fluctuate today
between 2500 and 1500 feet, before lowering to 750 to 1500 feet
overnight. Precipitation is likely to occur in 2 pulses for most
areas, one mainly this morning, and the other this afternoon in
some areas and in the evening for most others. We expect that the
Sexton Summit area on I-5, Siskiyou Summit on I-5, and the higher
passes will experience periodic problems from snowfall. This
afternoon and evening expect portions of the Illinois Valley and
Rogue Valley will be affected as snow levels lower. 850 mb
temperatures reach -6C and 700mb temperatures -16C with the last
wave of precipitation this evening. This usually pushes snow
levels down to about Obrien in the Illinois Valley and to about
Medford Airport in the Rogue. Please see your point-and-click
forecast on our website for expected accumulation at your
location.
Guidance has trended significantly downward with precipitation
amounts for late tonight into Thursday morning. For many areas
this will mean less of a snowfall threat for that time period, but
colder overnight lows. This will lead to black ice concerns for
that time period in areas where roads remain wet.
Showers Thursday will be minor, mostly just flurries, as weak
high pressure settles in. Friday presents another challenge as
another area of low pressure approaches with cold air in place.
Snow levels will likely be around 1500 feet. Current indications
are that this system will mostly affect coastal and near coastal
areas, and a winter storm watch might be needed for the Curry
County Coastal Mountains Friday night into Saturday. BTL

.AVIATION...22/12z TAF CYCLE...MVFR cigs/vsbys will be widespread
over the area this morning with isolated IFR cigs as showers persist
and gradually change to snow showers over many inland areas. Snow
levels across the area will lower from 2000 to 2500 feet elevation
down to near 1500 feet elevation this morning. Valleys west of the
Cascades could see a mix of snow and rain in the early morning
hours. However, little to no accumulations are expected at area
terminals west of the Cascades. East of the Cascades, expect light
snow accumulations in showers. Widespread MVFR cigs/visibilities
with showers will continue across inland areas late this morning
through at least this evening as showers persist over the area.
Along the coast, expect conditions to improve to VFR with areas pf
MVFR in showers early this afternoon, with these conditions
continuing into tonight. -CC
.MARINE...Updated 330 AM PST Wednesday 22 February 2017...Steep
seas of around 10 feet, dominated by west swell at 15 seconds will
continue through late this morning over the waters, mainly south of
Bandon. Seas will diminish below small craft advisory levels late
this morning and afternoon. Moderate to locally heavy showers will
continue today and tonight. Winds could be quite gusty with any of
these showers. Increasing northwest to north winds and seas are
expected tonight, continuing into Thursday. Seas are expected to
become steep and dominated by fresh north swell tonight through
Thursday afternoon. Showers will linger over the waters on Thursday.
A low pressure system will then move down from the north late Friday
into Saturday, bringing additional showers as well as the potential
for gusty south winds and steep seas. An active wet weather pattern
will continue into early next week. /CC
