Synopsis Smoke will continue to impact the region through at
least midweek with dry conditions and light offshore winds.

Seasonably mild, dry conditions will then persist through much of
the week and into the upcoming weekend. A pattern change will
potentially bring rainfall to the region around thanksgiving.

Discussion As of 9:51 pm pst Monday... Band of high clouds,
lighter offshore flow and smoke layer is all helping to keep temps
slightly warmer so far this evening with dewpoints trending
higher many places as well. These factors should mitigate
widespread temps falling to near or below freezing for the
interior valleys. Humidity values remain very dry in the hills
with single digit and teen readings still being observed and not
expected to change much overnight. Even though we are out of the
red flag conditions the fire weather concerns remain. Fuel
analysisshows most fuels at or well above all time record dry
levels for this time of year. Of course smoke impacts from the
camp fire continues to impact the region. Winds have eased across
norcal and this has allowed for less smoke dispersion, moreso
across the northern sac valley but also across the north bay and
greater bay area. Unfortunately thick smoke near the firelines can
limit the amount of aircraft usage for the firefight was well. So
good and bad comes with lighter winds. Upshot is to expect
another day of poor air quality most of the bay area on Tuesday.

Obviously future smoke production will be dictated by burning
conditions on the camp fire. Smoke and haze will continue to knock
a few degrees off MOS guidance but in general expect daytime
highs upper 60s to lower 70s most areas this week. Light offshore
winds and low humidity will be a main theme through at least
Thursday.

High confidence for dry weather continuing through the weekend
with perhaps a few degrees of cooling with daytime highs more 60s
than 70s. Return of onshore flow should actually keep overnight
lows a little warmer this weekend as well.

Long range forecast is where all the interest is now. General idea
shows the first storm dropping off the coast and heading towards
socal as an initial system that tries to weaken the ridge. Some
model consistency showing a more organized trough around nov 21st
and into thanksgiving but were still about 10 days out so
confidence remains low on details though a change in the longwave
pattern looks to be in the cards. New 00z ECMWF will be in
shortly. Latest 00z and 18z GFS backed off slightly but ensembles
remain favorable overall for a pattern change for the end of
november.

Prev discussion As of 01:00 pm pst Monday... Not a lot has changed
from this morning - heavy smoke continues to blanket much of the
region with moderate to unhealthy air quality. The smoke is also
impacting temperatures and have adjusted many locations a few
degrees downward to due decreased sun.

Only minor day to day changes are expected with the over sensible
weather for much of the upcoming week. High pressure aloft will
gradually shift eastward and weaken roughly midweek. In the short
term, smoke will continue to impact much of the region keeping
temperatures slightly cooler. The extent of smoke coverage is a
little tricky as a lot will depend on how much smoke is produced
from the camp fire and minor shifts in the surface winds.

Overnight lows will continue to drop to in the 30s at night for
interior valleys. Current forecast will include some patchy frost
for locations colder than 33 degrees, but not widespread enough
for a frost advisory.

The million dollar question continues to be, where's the rain? It
seems like the longer range models have been fine tuning a pattern
shift, but keep kicking it farther down the road. The last few
days the targeted pattern shift has been early next week into
thanksgiving. The latest 12z model suite still shows this thinking
with a trough and possible rain next week. However, the GFS and
ecmwf are at odds with details and timing. Conf still remains low.

None the less, latest official seven day forecast will bring some
light rain to the north bay late Tuesday with slightly cooler
temps. CPC 8-14 day outlook is now showing higher than normal
chance for a wetter pattern as well for ca. Stay tuned.

Aviation As of 10:04 pm pst Monday... MVFR-ifr in smoke and
poor to very poor slant range visibilities through the period.

Light offshore winds tonight and Tuesday morning except gusty in
the salinas valley Tuesday morning. Large scale offshore pressure
gradient weakens Tuesday allowing weak onshore wind to develop by
afternoon. A sharp 500 mb ridge becomes replaced by a dry 500 mb
trough Tuesday, divergence in jet stream winds brings increasing
high clouds tonight and Tuesday.

Vicinity of ksfo... MVFR in smoke. Poor to very poor slant range
visibility. Light offshore wind becoming onshore 5-10 knots Tuesday
afternoon and evening.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... MVFR in smoke. Poor to very poor slant
range visibility. Winds mainly light offshore tonight into Tuesday
except gusty e-se winds in the salinas valley Tuesday morning. Winds
variable to weak onshore Tuesday afternoon and early evening.

Marine As of 9:36 pm pst Monday... Generally light southerly
winds will continue through tomorrow as a system passes by to the
north. Winds will become northwesterly again around mid-week as
high pressure builds back in over the eastern pacific. Light mixed
swell will continue through mid-week before a northwest swell
arrives.
