AREA FORECAST DISCUSSION
National Weather Service Eureka CA
321 PM PST Sat Nov 26 2016

.SYNOPSIS...Periods of showers and high elevation snow will
continue tonight as a vigorous upper level trough moves across
the region. The rain will ease up on Sunday. A weaker trough will
follow Sunday night and produce light rain amounts through early
Monday.

&&

.DISCUSSION...A strong northwesterly jet max coupled with moist
onshore flow will continue to generate periods of showers through
tonight. The jet max will start to shift eastward and the onshore
flow will ease up during the day on Sunday. Weak instability and
daytime heating may result in some spotty light showers over the
mountains. Most lower elevations will see a break in the wet weather
by Sunday afternoon as a ridge builds closer to the coast. A weak
trough will move over the top of the ridge in NW flow Sunday night
into Monday morning. This shortwave trough does not look very
impressive at mid and upper levels, but low level advection and
surface wind fields show a well defined front moving across our
area by early Monday morning. Amounts will probably be relatively
low overall, but most locations will see measurable rainfall.

Snow levels have been at or above 4000 feet today, based on
surface observations across the area. The exception has been NE
Trinity county where surface reports suggest the potential for
snow as low as 3500 ft. Levels will fall to around 3500 feet
throughout tonight and may briefly dip down to 3000 ft early
Sunday morning. The GFS continues to be much warmer compared to
the NAM. Even at 3500-4000 feet there will still be travel
impacts, primarily on route 36 over South Fork Mountain Summit
tonight. A winter weather advisory remains in effect for elevations
above 3500 feet. Wet slushy snow may occur around 3000 feet,
however confidence is not high it will stick to the pavement and
create travel difficulty on 299.

A small scale surface low produced wind gusts to 50 mph at both
Crescent City airport and the NOS tidal station today. Winds have
been slowly dropping off this afternoon. Westerly winds have
developed behind the boundary and blustery conditions will
continue through late afternoon or early evening. Lighter winds
are expected later tonight and Sunday.

Surface high pressure and an offshore flow regime will start to
take shape on Monday after a front exits the area to our southeast.
Northerly flow and shallow instability near the coast may continue
to generate some showers through Monday night. Most showers will
remain over the coastal waters Mon night. The rest of the area
will be dry with cooler overnight lows. The clearing and cooling
will likely be modulated by fog and low clouds in the interior
valleys.

Overall we are looking for drier weather conditions along with
colder nights through much of next week. The one fly-in-the-ointment
will be another weak trough that will move over the ridge around
mid week. It does NOT look like a very wet and vigorous system in
the model data, but more measurable precip will definitely be
possible. The GFS and ECMWF have slowed down the front. It looks
like late Tue Night and Wed before we see more light. Offshore
flow will spring back up toward the latter portion of the week and
dry weather along with cold mornings will return.

&&

.AVIATION...VFR to MVFR conditions and moderate to moderate
and gusty winds will continue at KCEC and KACV through this
evening. MVFR to IFR conditions and moderate and gusty winds will
occur at KCEC and KACV late this evening through Sunday morning.
The lower conditions will be due to showers and/or patchy fog
reducing ceilings and/or visibilities. VFR conditions and light
winds will occur at KCEC and KACV Sunday. MVFR to IFR conditions
and light and variable winds will continue at KUKI through early
Sunday morning. The lower conditions will be due to showers and/or
patchy fog reducing ceilings and/or visibilities. VFR conditions
and light winds will occur at KUKI Sunday.

&&

.MARINE...Large west to northwest swells generated by low pressure
systems across the Pacific Ocean will continue propagating across
the marine areas through the middle of this week. The winds will
diminish slightly Sunday across the waters. A cold front will
approach the region Sunday evening. The winds will increase Sunday
night and Monday. Showers will move across the waters at times
through early this next week associated with the frontal boundary.
Small craft advisories will remain in effect across all the waters
through Tuesday morning due to winds and/or seas. Small craft
advisories will likely be extended through the end of this next
week due to elevated seas and/or increasing winds. Winds and seas
will be higher across the outer waters and in or near showers.
