AREA FORECAST DISCUSSION
National Weather Service Eureka CA
207 PM PDT Sat Apr 22 2017

.SYNOPSIS...Light isolated shower activity is expected across the
region through Sunday. A series of storm systems will then impact
the Pacific Northwest Monday and Tuesday, resulting in moderate
rains and locally gusty winds over northwest California.

&&

.DISCUSSION...Post frontal cloudiness and isolated showers were
occurring across the region this Saturday...and these conditions
are forecast to persist into Sunday. A storm system then
approaches the OR/WA coast Sunday night, while to its south, a
plume of PW values from 1-3 standard deviations above climatology
impinges upon NWRN CA. Moderate, to perhaps locally heavy rain, will
develop as a result, particularly over Humboldt and Del Norte
Counties. This initial wave of unsettled weather exits the region
by Monday afternoon, and will be followed by a second wave Monday
night into Tuesday morning. Storm total QPF values over this two
day period are expected to range from 1-3 inches over the northern
half of the CWA...to less than an inch over the southern half.

After Tuesday...light rain chances continue into Wednesday as
minor upper impulses move southeast across the area within NWLY
flow aloft. By Friday, an upper ridge is forecast to amplify
offshore over the Pacific. This will yield a drier and
potentially milder pattern heading into next weekend.

&&

.AVIATION...High pressure has built in the wake of a front that
pushed through the region early Saturday morning. VFR conditions
have been prevailing through the day at all terminals after MVFR
conditions early this morning. See no reason to go against
persistence for the next several hours. Brief lower ceilings,
around 2000-3000 feet, will no doubt be possible this evening,
however easterly flow in advance of another trough will likely
produce some low level drying this evening. The next trough will
generate another push of shallow moisture that will result in
increasing chances for MVFR ceilings and reduced vsbys in light
rain and mist at coastal terminals early Sunday morning. Even KUKI
may see reduced ceilings Sunday morning. Current indications are
for drier conditions and improving ceilings to develop Sunday
afternoon. This will need to be re-evaluated by later shifts for
the potential for longer lasting MVFR ceilings especially at KCEC.

&&

.MARINE...Southerly winds are relaxing this afternoon as high
pressure develops offshore from CA. Winds are then forecast to
strengthen to small craft levels Sunday night and Monday as a
storm system impacts the Pacific Northwest. Otherwise...a
westerly swell in the 10 to 15 second range will persist through
much of the upcoming week. Wind waves will also build in response
to passing frontal systems Monday and Tuesday...followed by small
craft seas associated with the longer period swell Wednesday and
Thursday.

&&

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