Area Forecast Discussion
National Weather Service San Francisco Bay Area
412 PM PST Wed Dec 9 2020

.SYNOPSIS...Main concern remains along the coast with high surf and
hazardous beach conditions through this afternoon. Expect a
cooling trend for the rest of this week with Friday morning
bringing the coldest minimum temperatures. This week also marks a
transition into a return of low clouds and fog with the potential
for inland intrusion into the valleys on Thursday. Then we'll
wrap up the weekend with light rain...best chances across the
North Bay but could extend southward towards the Monterey Bay area
at times.

&&

.DISCUSSION...as of 1:48 PM PST Wednesday...A mix of sun and
clouds across the Bay Area and Central Coast today as an upper
slow spins well to the the south and a weak boundary approaches
from the north. This gradual shift in the pattern has ended the
warm offshore flow. A quick check of the 24 hour trend shows many
locations running a few degrees cooler than yesterday. The winner
is Monterey, which is 24 degrees colder thanks mostly to no east
wind.

For tonight - the upper low to the south will eject to the east
and the boundary to the north will push through with little
fanfare. The cloud deck overnight may have a summer like stratus
feel to it, but not super confident on widespread stratus. Behind
the boundary a little bit of clearing of high clouds is possible
late tonight, but more notably will be the northerly wind shift.
The northerly to northeasterly wind shift will occur over the higher
terrain tonight leading to milder temps in the hills with
moderate humidity recovery.

The cooling trend will continue on Thursday with another weak
frontal boundary and more so on Friday. In fact, by Friday it
will feel even colder given the stronger onshore flow and air
coming off a relatively colder ocean. Highs on Friday will be in
the 50s to lower 60s...or a few below normal.

As mentioned on previous discussions a pattern change is in the
forecast for the weekend with the return of rain. Fortunately,
this is exactly the way one would want rain to return with
numerous burn areas. Point forecasts over the burn areas do not
show rain rates of concerns. As always though, with any rain on a
burn area we'll be watching closely.

A low pressure will gradually approach the region from the west
Friday night. A warm front will ultimately lift over the area
spreading light rain amounts Friday night and Saturday. Southern
portions of Monterey/San Benito may not see much light rain from
the warm front. Rain chances move farther north late Saturday as
the warm front lifts northward. More widespread rainfall is then
expected on Sunday as a cold front moves through. Rain amounts
Friday night through Sunday night will be 0.75-1" far North Bay -
SF Bay 0.25-0.5" - less than 0.25" to the south.

Drier weather return early next week, but longer range models show
that additional rain chances will be possible over Northern
California.

&&

.AVIATION...as of 04:10 PM PST Wednesday...For the 00z TAFs. VFR
this evening and overnight, along with light winds. Some concern
for possible MVFR to IFR ceiling onset at KSFO, KOAK and KMRY during
the morning on Thursday as next boundary approaches with rapid
moistening and deepening of the boundary layer. However, cooling
aloft may break up the inversion layer and diminish low cloud
coverage. Currents tafs persist in trending optimistic but will
reexamine when new 00Z model output received this evening.

Vicinity of KSFO...VFR, mainly light and variable wind becoming
onshore this evening into Thursday morning. Low confidence in VFR
forecast for Thursday morning.

SFO Bridge Approach...Similar to KSFO.

Monterey Bay Terminals...VFR, light offshore winds though locally
onshore the remainder of the afternoon into the early evening. Low
confidence in VFR forecast for KMRY Thursday morning.

&&

.MARINE...as of 2:17 PM PST Wednesday...Moderate long period
swells will slowly subside overnight into Thursday. Gusty
northwest winds will increase overnight into Thursday, especially
across the offshore waters as a weak cold front passes through the
waters. Northwest wind and seas will persist as another cold
front passes through Thursday night into Friday. Winds will turn
southerly by Friday night as a warm front approaches the region
but with generally light seas. By late in the weekend or early
next week another large nw swell will pass through the waters.
