Synopsis High pressure will result in dry and warm afternoons
accompanied by cool nights through the weekend across the
interior. Meanwhile, fairly persistent low clouds and cool
temperatures are expected along the coast. A weak front will bring
a chance of light rain to the north coast late Tuesday.

Discussion Weather today has been very similar to yesterday for
most of northwest california. This isn't really a surprise... As it
was our forecast. A blocking upper-level high drifting to our
north typically means persistence forecasts will work well, and
today has not been much of an exception. Temperatures are running
a few degrees above yesterdays levels across the interior valleys,
with many locations reaching into the 80s. After another cool
night tonight, expect similar warmth on Saturday afternoon. Have
opted not to go with another frost advisory tonight, as the
coldest temps this morning were barely into the mid-30s in those
locations where the growing season is continuing, and should be a
little milder tonight.

Meanwhile at the coast, stratus is behaving like yesterday with
similar coverage along a fair amount of the coastal plain. Some
fortunate areas will see a few hours of sunshine, but most beach
locations and areas around humboldt bay will likely stay socked
in. As the aforementioned upper high drifts off to our east later
this weekend, some slight cooling aloft would tend to favor a bit
more afternoon clearing for the coast. However, low-level winds
are only forecast to become lighter, and even tending southerly,
which does not usually help prospects for near-coastal sunshine.

Will continue to forecast some afternoon clearing away from the
beaches Saturday through Monday, but honestly if you have been
mostly cloudy yesterday and today, I would not expect much better.

Dry weather will persist through at least Monday, though with the
upper-high giving way, inland high temps will begin to cool. This
trend will continue into the middle of the upcoming week. However,
model guidance continues to trend drier, with the first 'front' on
Tuesday night looking rather weak. The mid to late week systems
are looking fairly progressive and focused more to our north. Have
trended rain chances lower accordingly. Aad

Aviation Marine stratus continued to straddle the coast today with
some areas of binovc in the early afternoon. A morning acv pirep
confirmed the marine layer at about 1500 feet as also indicated on
the acv profiler. Limited scattering along the coast still
expected, but the low clouds also expected to fully return across
the coast this evening. Model data showing some drier offshore
flow in the morning... Resulting in earlier Saturday morning
clearing. However, was uncertain on this morning's tafs if
offshore could offset low clouds and fog from reoccurring on
Saturday morning. Inland areas including uki should continue to
have unrestricted conditions. Ta

Marine N winds will increase a bit over the area today, with
the strongest winds in the NW corner of outer zone 470. This will be
enough to generate some marginal small craft advisory seas in the
outer waters from this evening through mid-morning Saturday. W-nw
swell at around a 13 second period will persist into early next
week, with a fresh batch of NW well arriving thereafter. Longer
period SW swell will continue through much of the forecast cycle as
well. Sec

Fire weather Still going to headline some locally gusty
ridgetop winds tonight for the interior, as east-northeast winds
will pick up somewhat... With perhaps some gusts 20 to 25 mph in
exposed locations. This is somewhat of a concern given just how
dry it has been, with continued low rh this weekend, but red flag
conditions are not anticipated. Winds will be lighter from mid-
morning Saturday through Monday, with gradually improving rh
heading into the upcoming week.

Eka watches warnings advisories
Ca... None.

Northwest california coastal waters... Small craft advisory until
9 am pdt Saturday for pzz470-475.
