Area Forecast Discussion
National Weather Service Eureka CA
249 PM PDT WED MAY 18 2016

.SYNOPSIS...Much cooler, cloudy, and rain showers through the
weekend. Gale force northerly winds through Thursday, then
subsiding winds and seas by Friday. Cool and drier conditions for
early next week.

&&

.SHORT TERM (Wednesday evening through Saturday night)...
Early afternoon satellite imagery shows that sunny skies across
the CWA. However, there are some stubborn low clouds hanging
around from Eel River to Humboldt Bay into Arcata and then to just
south of Crescent City. With daytime heating and some mixing in
the lower part of the atmosphere, the low clouds should be
dissipating by late Wednesday afternoon. Temperatures rose to the
upper 80s to near 90 degrees across the Interior, while coastal
areas temperatures tried to rise to around 60 degrees. The sunny
and warm weather, however, is coming to an end, as an unseasonably
strong upper level disturbance drops south from Southeast Alaska
into the Pacific Northwest and Northern California in the next day
or so. On Wednesday night, put in areas of drizzle along the
coastal area and interior low-lying valleys. Most of the solid
cloud cover and rain showers should remain mostly offshore
overnight. NW California should start to feel the influence of the
upper disturbance starting on Thursday.

This upper level disturbance is unseasonably strong for this time
of year. The GFS Ensemble is progging to this disturbance to be
about 180 to 240 m below normal for the 500-mb height. So what
this means for the Northwest California will be much cooler,
cloudy and elevated chance of rain showers starting on Thursday.
Instead of highs in the 80s, the Interior locations will see
temperatures in the low to mid 60s, while coastal areas will see
highs around 60 degrees. Mostly cloudy to cloudy skies should
persist through the end of the short term forecast period on
Saturday night. Showers will be impacting Northwest California for
the same time period. Do expect some convective potential during
the day on Friday and Saturday. With the origin of this system
coming in from the north, do not expect too much moisture to be
accompanied with it. QPF should be fairly light.

Forecast confidence is about average, as it is fairly difficult to
time individual disturbances spinning around the large-scale upper
level system as it remains over Northwest California. Utilize a
blend of ECMWF/GFS/GEM/and high resolution models in refreshing
the forecast package. /RCL

.LONG TERM (Sun-Wed)...
Sunday will be a transition day as an exiting low moves east of
CA while another trough approaches from the PacNW. NW CA will sit
in between these two systems with heights at H5 building to 567DM
which should translate to a fairly nice precip free day...although
a caveat that the European model does show the next low possibly
bring some showers to the region so confidence low on Sunday
still. Multiple shortwaves will move through the the cwa through
Wednesday associated with the next system however precip amounts
look low amounting to only some light shower activity across the
interior...while temperatures should remain near to slightly below
normal.

&&

.AVIATION...
Coastal stratus lingered along the north coast this morning and
began to show improvement early this afternoon as clouds scattered
out. Lingering pockets of stratus may afflict kcec and kacv through
mid-afternoon otherwise expect mostly blue skies across much of
northern California through the early evening. Satellite imagery
showed a a cloud deck associated with the approaching upper trough.
This deck will begin to move over the northwest California between 5
and 8 PM bringing VFR to MVFR ceilings across the region. Ceilings
may periodically lower late tonight as the passing trough brings
drizzle around Humboldt Bay and light rain across northern Del Norte
County. Conditions should improve behind the weak front early
Thursday morning. /KML

&&

.MARINE...
A strong ridge of high pressure across the eastern Pacific will keep
the pressure gradient flexed and maintain northerly gales through
this evening. By early Thursday morning a weak passing front will
cause the gradient to relax north of Cape Mendocino. A small craft
advisory will likely be needed following the gale warning for the
northern outer waters as winds are forecast to gust around 20 to 30
kt through Thursday afternoon. Winds will decrease further on Friday
as a the ridge offshore weakens and a broad surface low moves over
the western United States. This will keep the pressure gradient
relaxed with light to moderate winds expected through the weekend.
Note, however, that some southerly winds should develop nearshore
north of the cape as weak surface low moves across the region on
Saturday afternoon. North winds aren't expected to increase again
until possibly the middle of next week when offshore ridging builds
towards the west coast.

The sea state for the near term will be dominated by large, steep
waves driven by the gales offshore tonight. The steep waves will
gradually subside in response to the decreasing winds Thursday and a
mid-period northwesterly wave system will propagate the waters
through the weekend. Another feature to take note of will be a small
southerly swell generated from a southern hemisphere storm. This
will propagate the waters tonight reaching just about 1 to 2 ft.
around 17 seconds by Thursday afternoon. This will have minimal
impact across open waters but may create some set behavior in south
facing ports and anchorages. /KML
