Area Forecast Discussion
National Weather Service Eureka CA
314 PM PDT SUN JUN 19 2016

.SYNOPSIS...Dry through next weekend. Warm in the interior locations,
with highs in the low 90s. The main storm track remains north of NW
California. Looks like weather disturbances will be steered more
towards Oregon and Washington states.

&&

.DISCUSSION...Early afternoon satellite imagery shows sunny skies across
Mendocino, Humboldt, and Trinity counties. However, there is a SW-NE
cloud band that is bringing some mid to high clouds to Del Norte
county. Do expect clear skies overnight for most of NW California.
However, marine stratus may sneak into coastal area overnight.
Should be a sunny start to the work week. The work week should be
dry, with daytime highs in the 80s and 90s for the interior
locations, and 60s along the coast. There will be nightly
development of marine stratus along the coast.

There will be a weak upper level disturbance that will make landfall
in Washington state Monday night, and that may increase sky cover
slightly for the northern area. Another upper level disturbance will
drop from Haida Gwaii southeastward and make landfall over
Washington state Thursday. Right now, looks like this will bring in
increased cloud cover for the northern area. For the upcoming
weekend, looks like models are suggesting another short wave to head
towards Oregon coast, and that may bring increased cloud cover to
our area. However, models are struggling to handle the timing and
track of these upper level disturbances. The general idea is that NW
California should stay dry and fairly warm, with highs in the
60s along the coast, 80s and 90s inland.

Forecast confidence remains below average. According to the GEFS,
the relative measure of predictability is pretty low, around 10 to
30 percent, from Thursday onward. Thus, changes to the previous
forecast package is minimal. Hopefully the models will come into
better agreement. /RCL

&&

.MARINE...Model continuity continues to improve through the mid-week period,
adding confidence to the forecast. They show a shortwave trough
extending from the Pacific Northwest, with possible cyclogenesis in
the base of the trough several hundred miles offshore, and a massive
600dkm ridge extending from SOCAL to the Mississippi River. Closer
to the surface, an area of high pressure (centered near 40*N,150*W)
will extend east to Northwest California, with northerly winds on its
eastern flank continuing to affect our neck of the woods. As this
area of high pressure strengthens, wind speeds will continue to
gradually increase. In fact, this trend has been seen this afternoon
as some of the outer buoys are showing winds approaching 20 knots.

Not much change in the pattern described above is forecast through
Wednesday. We were tempted to extend the current advisories in place
through this time, as the latest guidance would support this.
However, given the trends for higher wind speeds has been a recent
(last 24 to 30 hours) development, we decided to hold off for
another forecast cycle to see if this trend changes.

Overall, expect northerly winds in the 20 to 30 knot range to
continue across the outer waters, with waves less than 10 feet and
periods less than 10 seconds. For the coastal waters out to 10
nautical miles, winds and waves will be lighter, with no headlines
needed at this time. Additionally, a southerly swell will persist
through much of the week. /PD

&&

.AVIATION...Along the Coast this morning...patchy marines clouds developed from
Humboldt Bay-Arcata Airport with brief IFR cigs by late morning.
The vis remained unrestricted. Other than the coast...VFR conditions
prevailed across the Region today with no significant aviation
hazards. An Influx of mid-high clouds...associated with an offshore
upper level trough...continued to stream into the region through
afternoon. Overnight/tomorrow morning...the patchy coastal marine
clouds may very well be a repeat of yesterday with perhaps a
slight increase in coverage. Also...patchy fog is also probable.

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...NONE.
NORTHWEST CALIFORNIA COASTAL WATERS...
     Small Craft Advisory until 9 PM PDT Monday FOR PZZ470-475.
