AREA FORECAST DISCUSSION
National Weather Service Eureka CA
259 AM PDT Mon Apr 10 2017

.SYNOPSIS...The showers will quickly taper off this morning to
bring a mainly dry day across the area. Late tonight another
system will bring light rain to the area on Tuesday. Showers will
persist Wednesday morning with heavier rain late in the day.
Showers are expected Thursday with drier conditions possible
Friday and Saturday.

&&

.DISCUSSION...Fairly robust showers are moving through the
northern portion of the area this morning. These are expected to
diminish fairly quickly this morning resulting in a mainly dry,
but cool day. Expect skies will be partly cloudy today.

Late this afternoon and evening clouds will start to increase as
the next system approaches the area. This system is an area of low
pressure associated with a shortwave moving along the nearly zonal
H500 flow. and then curving north before it reaches the coast.
Southerly winds will pick up ahead of this system and keep
temperatures quite warm overnight. A few showers are possible
overnight with this system, but most of the precip is expected to
hold off until Tuesday afternoon when the low finally gets closer
to the coast. Current model runs show this low deepening slightly
as it approaches the coast to around 998 mb. This will bring
gusty winds to the Humboldt and Del Norte coast once again Tuesday
afternoon and evening. Current model runs are show an inversion
keeping most of the winds over the ridges, but this will need to
watched. A wind advisory may be needed for the ridges. The 06Z GFS
run shows 55 KT at 925 mb over CEC Tuesday evening (06Z on
Wednesday). This system will bring light to moderate rain to the
area on Tuesday. Snow levels are generally expected to be above
4500 feet with this system.

Tuesday night a warm frontal boundary is expected to bring some
light rain to the area and this will lift snow levels as well.
Breezy south winds are expected to persist which may limit the
rainfall amounts around Humboldt bay due to downsloping. Warm and
breezy conditions with occasional showers will continues through
the first half of the day on Wednesday. Late in the afternoon a
cold front is expected to move onshore bringing moderate rain to
the area. Gusty south winds are expected with this front as well.
Models are in fairly good agreement on this front moving through.

Late Wednesday night behind the front snow levels are expected to
fall and there will be some showers around. Showers are expected
to persist on Thursday. Showers will persist and snow levels are
expected to fall to around 3000 to 3500 feet, but this may need to
be lowered if models remain consistent.

The GFS and ECMWF are in fairly good agreement the Friday and
Saturday being mainly dry with just a few showers around. The
model discrepancies start on Sunday when the ECMWF brings a strong
system through and the GFS keeps the area mainly dry until Monday
when the system moves through. MKK

&&

.MARINE...A weak cold front moved across the waters early this
morning producing a few showers across the region. The seas
increased and an elevated westerly swell will propagate across the
waters through early Tuesday morning. A high pressure ridge will
build across the region today in the wake of the front. The seas
will gradually subside Tuesday. Small craft advisories will
continue across all the waters through early Tuesday morning. A
weak cold front will move across the region Wednesday increasing
the winds Tuesday night and the short period seas on Wednesday. A
high pressure ridge will build across the region Thursday in the
wake of the weak cold front.

&&

.Aviation...VFR to MVFR conditions will continue at KCEC, KACV
and KUKI early this morning. The lower conditions will be due to
reduced ceilings as a few showers associated with a weak cold
front traverse the region. Winds will continue light to moderate
early this morning. Ceilings will increase later this morning and
today as a high pressure ridge builds across the region. VFR
conditions and light to moderate winds will prevail at KCEC, KACV
and KUKI late this morning through tonight with light to moderate
winds occurring.

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...None.
NORTHWEST CALIFORNIA COASTAL WATERS...
