AREA FORECAST DISCUSSION
National Weather Service Eureka CA
343 PM PDT Thu May 18 2017

.SYNOPSIS...Dry weather and increasingly warm temperatures will
prevail across much of the region through next week.

&&

.DISCUSSION...The large-scale upper air pattern will be dominated
by a ridge of high pressure centered over the NERN Pacific and
adjacent coast throughout the extended forecast period. As a
result, clear skies and warm to locally hot daytime temperatures
will become probable for interior locations. Minor upper
disturbances will pass across the area Saturday afternoon, and
possibly Sunday afternoon. The atmosphere is forecast to
destabilize over the mountainous interior with each disturbance,
such that a non-zero threat for a shower exists. Best chances for
any thunderstorm activity may be toward mid week when mid and
upper flow becomes south and southeasterly. Given that we are
still talking 5 or 6 days our the probability is too low to
include in the forecast at this time. Otherwise, dry weather will
prevail. A change from the earlier forecast package includes
eliminating the coastal cloud cover and fog due to nightly
offshore flow on Sunday and Monday. This combined with max h5
heights may give rise to a very warm day along the north coast on
Monday. Marine air looks to return beginning Tuesday.

&&

.AVIATION...Surface high pressure combined with a strong upper level ridge
will dominate Northwest California's airport/airfields through the
TAF period...and keep mostly VFR conditions across the region.
However, along portions of the Redwood Coast by late morning,
stratus fragments developed and were blowing in/out of Humboldt Bay
to ACV. Strands of stratus caused ACV airport to drop briefly to IFR
(BKN006-008)...the clouds were initially so thin that it was not
easily seen on VIS Satellite. Later about 1 PM, an offshore stratus
field was growing...so a brief period of IFR CIGS may occur at ACV
this afternoon. A thermal (heat) trough will interact with the high
pressure resulting in afternoon breezy winds. Conditions will remain
VFR across the interior...including UKI.

&&

.MARINE...High pressure continues to dominate the weather pattern
with some residual northerlies plaguing mainly the outer waters.
This should continue to be the trend for the next 18 to 24 hours,
before high pressure begins to strengthen to our west and a weak
thermal/valley low develops. Resulting winds will likely gust
near 35 knots Friday through late Saturday, warranting the
issuance of a Gale Watch. A steep fresh swell will accompany
the winds ranging from the 10 to 12 feet.

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...None.
NORTHWEST CALIFORNIA COASTAL WATERS...Small Craft Advisory from 11 PM this evening to 5 AM PDT
     Saturday for PZZ470.

     Small Craft Advisory until 3 AM PDT Monday for PZZ475.
