AREA FORECAST DISCUSSION
National Weather Service Eureka CA
218 PM PDT Mon Apr 17 2017

.SYNOPSIS...A broad trough over the northeastern Pacific Ocean
will allow multiple weather systems to bring breezy south winds and
periods of light rain to the region through Wednesday. High
pressure will take over the second half of the week bringing
mostly dry weather and warmer temperatures.

&&

.DISCUSSION...Another cool and partially wet day across NW
CA...and this pattern is expected to persist through at least
Wednesday as a broad trough remains over the northeastern Pacific.
Expect convective showers for Tuesday as a cooler and slightly
unstable airmass moves over the region where the main albeit
slight threat of Thunderstorms will exist mainly across Trinity
County during the afternoon period. Convective parameters look
best farther to the east but a passing shortwave may be enough to
ignite storms over the higher terrain in Trinity which should then
track eastward over the central valley. A rumble of thunder will
be possible elsewhere but still does not warrant a mention of
storms. The final front will impact on Wednesday with Thursday
will not be totally rain- free as high pressure begins to build in
behind the weakening upper trough. Stronger ridging will set up
over the western United States bringing mostly dry weather and
warming temperatures for next weekend. Temperatures in the 70s
will be possible across the interior while the coast is looking at
more seasonal values. Models continue to suggest a weak system
may overtop the ridge and threaten our dry weekend, however, this
feature is more likely to dissipate as it impacts the ridge of
high pressure. At most, it could bring a few hundredths of light
rain to Del Norte County. Stay tuned. /kml/jt

&&

.AVIATION...Several weather systems will continue to impact The Redwood
Coast through the forecast period and spread across the interior.
The systems will mostly bring light rain and breezy southerly winds
to the coastal areas...especially at CEC. Brief moderate rain may
drop cigs/vis mainly into MVFR with occasional IFR conditions near
the far North Coast. Showers will impact the North Coast later in
the period.

&&

.MARINE...Marginal advisory level seas will continue through
tonight mainly in response to a very short period...but
conditions should slowly improve through the night.  Southerlies
will increase slightly again ahead of the next storm system by
late Tuesday night. Winds will decrease by Thursday and remain
light through the remainder of the forecast period. SW and NW
swell trains will decay over the next 24 to 48 hours. A more
significant westerly swell will arrive late tonight and Wednesday
with heights reaching 10 feet. /SEC/JT

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...None.
NORTHWEST CALIFORNIA COASTAL WATERS...Small Craft Advisory until 11 PM PDT this evening for PZZ470-475.
