Synopsis Widespread smoke and haze will continue to result in
poor air quality over much of the san francisco bay area through
the weekend. Otherwise, dry weather with mild temperatures are
forecast to persist through early next week. A significant pattern
change appears likely starting on Wednesday of next week, with
the potential for widespread periodic rainfall during the second
half of the week.

Discussion As of 02:00 pm pst Friday... Smoke and poor air
quality has continued to impact the region today, with the bay
area seeing the worst of the impacts. Visibilities are reduced due
to smoke with the livermore airport reporting the lowest
visibility at 3 4 a mile. Not expecting much change in smoke
coverage across the bay area as offshore flow continues to bring
smoke from the central valley through the bay area and the north
bay counties. Coastal areas may see some minor improvements in
air quality with an increase in onshore flow at times this
weekend. However, there is abundant smoke over the coastal waters
so not expecting onshore flow to improve conditions appreciably.

Smoke and poor air quality will continue to be an issue through
early next week.

Highs through the beginning of next week will be in the 60s to
lower 70s. This is a couple of degrees cooler than recent days, as
the ridge of high pressure overhead will weaken due to upper
level low approaching the ridge. Overnight lows will continue to
be cool in the valleys, with 30s to 40s expected. A surface low
just offshore will drive weak onshore flow and could see stratus
push into the bay area and along the coast tonight and again on
Saturday night. Will see an increase in offshore flow in the
higher terrain on Saturday night and into Sunday. Winds could be
breezy at times in the north and east bay hills with low relative
humidity, so fire weather concerns will continue through the
weekend.

Looking ahead to next week, models are in better agreement that
the first disturbance in a major pattern change will arrive on
Wednesday. There are significant differences between the GFS and
the euro on the amplitude of the shortwave trough, with the euro
much deeper and wetter. However, both the euro and GFS ensembles
are in good agreement of at least some precipitation over the
region. Have increased pops into the likely category during the
day on Wednesday. This pattern change will bring a return of
cleaner marine air, stronger winds, and precipitation which will
help to remove smoke from the area. The next trough is expected
to bring additional rainfall late on thanksgiving and into Friday,
with another trough possible over the weekend. These systems will
bring cooler temperatures, with rainfall amounts still highly
uncertain. While the timing and rainfall amounts of these troughs
is uncertain, confidence continues to increase that a major shift
towards a wet pattern will develop for our region.

Aviation As of 10:10 am pst Friday... Widespread impacts from
wildfire smoke, primarily throughout the sf bay area and delta.

Ifr visibility with periods of MVFR ceilings through the day. Weak
onshore push this afternoon may bring slight temporary
improvements later today, however, some areas such as koak could
see further deterioration in visibility as there is plenty of
smoke offshore to pull back inland. Poor slant range visbys
continue. Little relief from smoke through the weekend.

Vicinity of ksfo... MVFR-ifr visibility in smoke, light wind. Poor
to very poor slant range visibility.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals...VFR with periods of smoke through the
morning. Onshore wind shift later today will pull offshore smoke
inland, similar to yesterday afternoon, bringing generally MVFR
but possibly ifr visibilities late this afternoon through this
evening.

Marine As of 10:00 am pst Friday... Generally light winds will
continue through the weekend and early next week. A mixed moderate
northwest swell and light southerly swell will also persist. No
significant change in the weather pattern expected until mid week
next week at the earliest.
