AREA FORECAST DISCUSSION
National Weather Service Eureka CA
358 AM PDT Sun Jul 9 2017

.SYNOPSIS...A weak trough will bring slightly cooler temperatures
Sunday into early next week. Night and morning coastal clouds and
fog will persist with partial afternoon clearing. Warming
temperatures are expected once again late next week.

&&

.DISCUSSION...The typical summer like pattern continues as low
pressure sits over the Gulf of Alaska and high pressure dominates
off to our east. Subtle changes in the forecast will occur though
as the low tries to nudge its way east. The main factor from this
will be seasonable yet warm temperatures for interior areas while
coastal communities remain influenced by the marine layer.
Overnight offshore flow may reduce the expansion of stratus and
fog in Del Norte County, but other coastal communities will
continue to see the standard night and morning clouds with partial
afternoon clearing. These conditions are forecast to last through
mid to late week before high pressure takes over the forecast
leading to hotter temperatures for the weekend.

&&

.AVIATION...Stratus will continue to impact coastal terminals with
IFR conditions today. As of 10Z, KCEC, KACV and KFOT were reporting
ceilings around 500 feet or less. Daytime heating and mixing should
result in improvement away from the ocean by mid to late morning.
Closer to the ocean, expect stratus and perhaps reduced vsbys to
linger through the day. BUFKIT profiles continue to indicate weak
onshore flow and high boundary layer humidities again tonight under
a sharp marine inversion. Thus expect stratus to continue to impact
the coastal airports with IFR conditions tonight through Monday.
KUKI will remain clear through the period.

&&

.MARINE...Robust northerly winds offshore will continue through mid
next week as high pressure over the NE Pacific remains nearly
stationary. The persistent northerly winds in the offshore waters
will generate short period seas for the inner waters through the
early portion of next week. This will make ocean conditions rough
and uncomfortable. A small craft ADVISORY remains in effect for the
outer waters, 10-60NM from shore. The ADVISORY has been expanded
into the inner waters south of Cape Mendo, though most of this area
(PZZ455) will not see 20-25 kt of wind. The ADVISORY for the outer
waters may need to be upgraded to a WARNING if winds reach 35kt
and/or seas reach and exceed 10 ft.

&&

.FIRE WEATHER...Today's temperatures are forecast to be slightly
cooler than Saturday's with RH values falling in the afternoon for
zones 276 and 277. However, with the marine layer deepening
tonight and into Monday, RH values are forecast to have better
recoveries.

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...None.
NORTHWEST CALIFORNIA COASTAL WATERS...Small Craft Advisory until 9 PM PDT Tuesday for PZZ470-475.

     Small Craft Advisory until 11 PM PDT Monday for PZZ455.
