Synopsis A dry upper trough will maintain breezy weather
conditions through Friday. Near normal temperatures in the
interior today will warm slightly above normal this weekend
before another cooling trend commences next week.

Discussion Skies were mostly clear across the forecast
area overnight, according to satellite imagery. There were some
low clouds in the river valleys, mainly the van duzen. Expect
this will quickly dissipate in response to robust northerly winds
and mixing by mid morning. The northern edge of a more substantial
stratus cloud deck has been stationary along the mendocino-sonoma
county border through the night. The increasing northerlies has
thus far kept the stratus at bay and from surging northward up the
mendocino coast. Latest high resolution guidance from the hrrr,
arw and nmm indicate northerly-northwesterly winds picking up
today. This will force the stratus southward. Otherwise, expect
another day of sunshine with blustery gusty northerly winds for
the north coast.

Inland valley areas will also have breezy conditions today. This
will help to keep afternoon highs right around late june normals;
in the 80s. Geopotential heights rebound slightly on Friday and
temperatures should start to edge upward a bit in the valleys.

Gusty winds will likely put a cap on afternoon highs again, however.

Lows may start out "cool" Friday morning, in the lower to mid 40s
in some of the colder valleys. Strong north winds will also make
it miserable in the mountains, especially in the king range where
northerlies have been gusting to 55 to 63 mph for the last couple
of days nights.

Medium range deterministic models and ensemble forecast systems
continue to indicate a large trough dropping southward from the
gulf of alaska next week. This trough will bring cooling to the
interior. Highs inland will still be quite pleasant through, in
the mid 70s to mid 80s in the interior valleys. Frost is not
expected at this time for any of the interior valleys. Coastal
areas may also start to see more cloud cover, though there is
still a great deal of uncertainty regarding coastal stratus next
week as northerly flow offshore decreases.

Aviation Breezy north persist across much of the area along with
vfr conditions. The only places seeing any clouds currently are the
eel river valley and the southern mendocino county border. Both of
these location will expand slightly overnight, but confidence is low
that it will make it into either kacv or kuki. Northerly winds will
increase again this afternoon with gusts to 30 kt possible once
again along the coast. Tonight most areas are expected to stay clear
once again with a very similar pattern in place. Mkk

Marine A large area of surface high pressure located over the
nern pac combined with low pressure over cntrl ca and the great
basin continues to yield a tight pressure gradient over the coastal
waters of nwrn ca. Gale force northerlies are occurring as a result
over the eka outer waters. Those winds are producing steep hazardous
seas that are propagating across the eka inner waters. Model
guidance indicates these conditions will generally continue through
the weekend. However, Friday night into Saturday the winds and waves
start to diminish slightly. Winds may only be around 30 kt for the
weekend with a few gusts to 35kt. The gale warning and haz seas
warnings may need to be extended through part or all of the weekend,
but will let the next shift take another look at it.

Early next week it looks like winds and seas will diminish more
significantly, especially north of CAPE mendocino. This looks to
persist through much of the week. Mkk
