Synopsis for northern california waters..Light winds will transition to modest northerlies in most areas and localized southerlies along the immediate coast by Wednesday afternoon as high pressure strengthens over the northeastern pacific. This will cause steeper northerly waves to build overnight Wednesday, but even larger seas are expected Thursday morning through Friday morning as a more substantial west to northwest swell spreads across the coastal waters.

Synopsis The very dry late fall continues with mild afternoons
and chilly nights. Areas of smoke and haze will mix with a few
high clouds, dimming the otherwise sunny skies. Dry weather will
persist through the weekend while rain chances improve toward
thanksgiving.

Discussion The rbg cloud phase distinction product off of goes
16 has been especially useful the past few days to display the
differences between the mix of high and mid-level clouds,
localized coastal stratus, and layers of smoke across northwest
california. The smoke aloft and high clouds have clearly thinned
or cleared out across much of northwest california, but smoke and
haze has settled in closer to the surface, with poorer air quality
along some of the valleys and especially the north coast compared
to yesterday. Unfortunately while a passing trough has helped
clear the layers of smoke aloft and allow for more daytime heating
across inland areas, boundary layer winds remain very light. Hrrr
smoke modeling points toward some subtle improvement, so latest
thinking is that the air quality may improve slightly and should
not become any worse. However, surface winds still look very light
on Thursday, with the stronger northerly gradient staying
offshore, so expect some smoke and haze to continue to hang
around, especially the farther south one is from the oregon
border.

The other short-term questions will be stratus along the coast,
and any need for frost advisories tonight. With some warmer
temperatures and somewhat higher dewpoints along the coastal
plain,in areas that are still officially in the growing season,
slightly milder lows should be expected tonight, so have held off
on any frost advisories. Meanwhile stratus has shown up along
portions of the immediate mendocino coast, while the north coast
is still 'clear'. Some hi-res guidance points toward shallow fog
potential late tonight, particularly around humboldt bay, but
expect that it will be fairly localized and short-lived heading
into Thursday morning given the latest trends. Thursday night into
Friday morning may offer more of a potential for coastal
cloudiness from CAPE mendocino to crescent city. Otherwise,
sunny albeit hazy skies should continue into the weekend across
our region. Temperatures will vary little through the weekend,
with highs continued in the mid 60s to low 70s inland, and upper
50s to low 60s at the coast. A wetter pattern may finally arrive
late next week, though some model guidance hints at enough of a
threat that we have a slight chance of rain in the forecast
starting on Tuesday. Aad

Aviation Lingering smoke from distant wildfires continues to
slightly obscure visibilities at most area terminals today, although
generally only to around 4 miles at worst. Gradual improvement in
that regard can be expected overnight tonight and Thursday as
northerly winds increase. Otherwise, low stratus has remained
offshore as of late afternoon and terminals are generally
unaffected.

Late tonight, there are indications that very shallow low stratus
and fog may develop along the immediate coast, potentially impacting
both acv and cec. Given the extremely shallow nature of the moist
marine layer, confidence is very low regarding this development.

Flight categories along the coast will likely be boom or bust
overnight and tomorrow morning, either remaining clear andVFR
(lingering smoke notwithstanding), or tanking to lifr with
potentially 1 4 mile visibilities in the areas that fog develops.

Skies should clear tomorrow afternoon, but higher confidence
exists that more will develop tomorrow night. Brc

Marine While moderate northerly winds will develop across the
offshore waters overnight (with light southerlies along the
immediate coast due to a flow reversal), the more impactful
development will be the arrival of a building westerly swell
Thursday morning. While the aforementioned northerlies may push
wave heights to a steep 6 or 7 feet overnight, the building swell
tomorrow morning will cause seas to climb to around 11 or 12 feet.

These conditions will last Thursday morning through generally
Friday morning, and wave heights will gradually subside Friday.

For the remainder of the weekend and through mid week, generally
light and somewhat variable winds will prevail, and seas will remain
dominated by a modest northwest swell. There are some indications
that stronger southerlies and additional northwest swells may arrive
later in the week, but confidence is very low beyond mid-week. Brc
