UPDATED MARINE SECTION

.SYNOPSIS...25/212 AM.

Marine layer clouds with patchy fog will reoccur each night from
the coasts to the coastal valleys, expanding into the valleys
into this weekend. Temperatures will trend cooler, with below
normal temperatures through the weekend.

&&

.SHORT TERM (TDY-SAT)...25/212 AM.

The flow overhead will become more and more cyclonic as a very
large upper low works its way into and thru the PACNW. Hgts will
fall from 590 dam to 584 dam by Saturday afternoon. Moderate to
strong onshore flow will be present for all three day as well. The
onshore flow will be strongest (8-9 mb) to the east and in the
afternoons.

Look for three similar days today through Saturday. There will be
plenty of low clouds and fog covering almost all of the csts and
much of the vlys. Clearing will be slower than normal and a few
beaches will see no clearing at all. The low clouds will also
arrive earlier than normal as well. The only exception will be the
western portion of the SBA south cst where local north winds will
likely keep the region cloud free.

Max temps will fall 1 to 2 locally 3 to 4 degrees per day across
most of the area. By Saturday even the vlys will be in the 70s.
These max temps will be 3 to 6 degrees blo normal across the csts
and 6 to 12 degrees across the vlys.

There will be gusty west winds across the Antelope Vly in the
afternoons with peak gusts approaching advisory levels. There will
also be gusty NW winds across the SW portion of SBA county in the
evenings and overnight. These gusts will likely reach advisory
levels Friday evening.

.LONG TERM (SUN-WED)...25/237 AM.

June Gloom will continue unabated through at least the 1st of
July. A series of upper lows will rotate through the PACNW and
keep cyclonic flow over the state. Strong onshore flow to the east
will continue through the period. There will be moderate onshore
flow to the N in the afternoon, but only weak onshore flow in the
mornings.

Night through morning low clouds and fog will continue through the
period pushing over the csts and deep into the vlys. Clearing will
be on the slow side with some west facing beaches not clearing at
all.

Strong near advisory west wind gusts will affect the Antelope Vly
each afternoon due to the strong onshore push. NW winds will
likely continue to affect the SW corner of SBA County in the
evenings.

Max temps will not change much through the period. Looks for mid
and upper 60s at the beaches; lower to mid 70s across the rest of
the csts and mid and upper 70s across the vlys. These temps are 3
to 6 degrees under normal for the csts and 6 to 12 degrees cooler
than normal for the vlys.
