1006 am pst Fri nov 16 2018

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 around the middle of next week,
with the potential for widespread periodic rainfall during the
second half of the week.

Discussion As of 09:17 am pst Friday... Smoke and poor air
quality will continue to impact the region today, with the bay
area seeing the worst of the impacts. Visibilities are reduced
regionwide with visibilities as low as 1 mile in oakland and 1 to
2 miles at other reporting locations around the bay. Not expecting
much change in smoke coverage across the bay area as offshore
flow continues to drain smoke down the central valley through the
golden gate gap and out over the coastal waters. Coastal areas may
see some minor improvements in air quality with the possibility
for some weak onshore flow this afternoon. However, there is
abundant smoke over the coastal waters so not expecting onshore
flow to improve conditions meaningfully. Smoke and poor air
quality will continue to be an issue through early next week until
a pattern change occurs.

Overnight lows remained cool in valleys last night, especially
across the north bay where low to mid 30s were common. Smoke will
continue to keep high temperatures several degrees cooler across
the bay area than surrounding areas with highs in the mid 60s.

Other areas will see highs in the low-mid 70s. May see an increase
in smoke in our southern regions this afternoon as onshore flow
advects smoky air inland. Dry conditions are expected through
Tuesday. A major pattern change is still on track for the middle
of next week and into the holiday weekend. This will help to
remove smoke and bring rainfall to the area.

Prev discussion As of 02:52 am pst Friday... The main impacts across
the region in the short-term will continue to be smoke, haze and
associated poor air quality as a result of the camp fire inland to
our north. Poor visibility, below 1 1 2 sm at times, is being
reported across the greater san francisco bay area with
temperatures ranging from the middle 30s in our colder inland
valleys to upper 40s near the coast. Given the weak offshore flow
aloft, air quality is not forecast to improve much through the day
with unhealthy to very unhealthy conditions forecast (by the bay
area quality management district) across the bay area while
slightly better conditions are expected over the monterey bay
region.

The forecast models do indicate a slight increase in onshore flow
near the coast this weekend which may help to improve conditions.

May even see areas of low clouds develop over the pacific late
tonight with the potential for coastal intrusion by Saturday
morning. Something that will need to be closely monitored as smoke
may actually get trapped beneath the low level inversion.

Regardless, dry weather conditions will persist along with
temperatures above seasonal averages each afternoon through the
weekend and into early next week. Overnight conditions will be
seasonably cool, especially inland away from the coast.

Forecast confidence continues to increase regarding a major pattern
shift late next week that would bring unsettled weather conditions
to the region. An initial upper level system is forecast to develop
over the eastern pacific and approach the southern california coast
early next week, missing our region. However, the medium range
models are in better agreement with subsequent systems approaching
the region during the second half of the week. The gfs, ECMWF and
canadian are in decent agreement with the potential for widespread
rainfall developing over the region as early as Wednesday.

Additional systems appear likely to impact the region around
thanksgiving and potentially into the following holiday weekend as
well. With this said, timing and strength of each system remains
difficult to pin-point at this time given model-to-model and run-to-
run differences. Regardless, a more active pattern is appearing more
likely late in month which would also help to improve air quality
region-wide.

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.
