AREA FORECAST DISCUSSION
National Weather Service Eureka CA
341 PM PST Fri Feb 3 2017

.SYNOPSIS...A potent storm west of Oregon will continue to
produce occasional showers through Saturday. A second storm will
approach on Sunday, generating more rain and gusty winds by Sunday
night. Wet weather with periods of rain will continue next week.

&&

.DISCUSSION...A vigorous surface low NW of Cape Blanco Oregon has
been producing windy conditions and occasional showers through
the day today. The robust southwesterly flow has been borderline
for a wind advisory with gusts from 40 to 45 mph north of Cape
Mendocino. This low will slowly track northward this evening taking
the strong ribbon of southwesterly winds with it. Surface gradients
will loosen up more substantially on Saturday, however breezy
conditions will most likely continue especially over the coastal
headlands and over the ridges. The onshore SW flow will ease up on
Saturday, however we will probably still see terrain driven upslope
showers, primarily in Del Norte, Humboldt and Trinity counties
through Saturday night. The NAM/ARW/GFS and ECMWF also indicate
the potential for a warm front to develop offshore.

A surface front will develop to our NW on Sunday and then push
toward the region through the day on Sunday. The latest suite
of models all indicate a robust low level jet developing by
Sunday afternoon/evening and for southerly winds to accelerate
offshore and aloft as a surface wave develops on the front. The
NAM has 925mb winds of 60-70kt just offshore which is in the
realm of a high wind warning for the higher terrain. Confidence we
will see southerly winds of 60 mph or more for the coastal plain
is not high. Higher resolution model data may shed more light on
it as the event grows closer. The higher terrain of Del Norte,
Humboldt and even Mendocino counties will no doubt see gusts to 50
mph. It's almost a sure thing for the ridges north of Cape
Mendocino. We are probably going to need at least a wind advisory.

The front will push through Sunday night and produce yet another
round of moderate to locally heavy rain. The GFS has a rather
sharp boundary and wind shift line pushing through by midday
Monday, with widespread rain rapidly changing over to scattered
showers. Even though snow levels will fall to around pass level on
Monday, there may not be any snow shower activity for a winter
weather advisory for the mountain passes. We will have to wait
and see how this plays out. It is still 3 days out in the future.

After potentially a break in the wet weather Monday night, a
warmer storm will bring yet another episode of rain on Tuesday.
It will be interesting to see how quickly the snow levels rise on
Tuesday. This sort of overrunning pattern typically produces snow
for Trinity county. Snow levels will need to looked at closer over
the next couple of days. A warning for snow may be necessary if
snow levels remain around 2000-2500 feet Tue. Current indications
are for snow levels to rise up to 4kft or more.

Wet weather conditions will likely continue into Wed as the warm
front buckles and slowly lifts northward across the area. We may
see some drying with lower chances for rain around midweek,
however another storm will quickly approach by Thu for another
round of wind and rain. Each successive rain episode will increase
the probability for rising water levels on creeks, streams and
rivers. Hydrologic hazards may become an issue during the latter
portion of the week. We will have to continue to monitor each
event for the possibility of sustained heavy rain.

&&

.AVIATION...MVFR to IFR conditions and moderate to moderate and
gusty winds will continue at KCEC, KACV and KUKI through Saturday
morning. Showers will continue moving through the area at times
through Saturday morning. The lower conditions will be due to the
showers and reduced ceilings and/or visibilities. Moderate to
moderate and gusty winds will prevail at KCEC, KACV and KUKI
through Saturday morning.

&&

.MARINE...The winds and seas are diminishing across the waters
in the wake of a cold front. However the winds and seas will
increase Sunday as a cold front approaches and moves through the
region. Small craft advisories will continue in effect across the
Southern outer waters and the near shore waters through early
Saturday morning. A small craft advisory will be in effect across
the northern outer waters through Saturday evening due to the
winds and seas. A gale warning may be necessary across the outer
waters Sunday and Sunday night due to increasing winds associated
with Sunday's cold front. The winds and seas will diminish across
all the waters Monday and early next week in the wake of Sunday's
cold front. Small craft advisories are likely across the near
shore waters Sunday and Sunday night due to increasing winds and
seas associated with Sunday's cold front.

&&

.EKA WATCHES/WARNINGS/ADVISORIES...CA...None.

NORTHWEST CALIFORNIA COASTAL WATERS... Small Craft Advisory
until 4 AM PST Saturday for PZZ450-455-475. Small Craft Advisory
until 9 PM PST Saturday for PZZ470.
