Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries...
gentle to moderate westerly breezes continue through the weekend with chance for rain across the northern waters. Northwest swell will build today into Sunday, resulting in elevated seas of 8 to 10 feet that will be hazardous to small craft across the northern waters. A series of larger northwest swells with a 16-20 second period will result in a continuation of elevated and hazardous seas through much of the upcoming week.

New SYNOPSIS, SHORT TERM, LONG TERM, MARINE

SYNOPSIS
Issued at 233 AM PST Sat Dec 2 2023

Cool, unsettled weather for the next few days followed by a warming trend into early next week. An approaching trough of low pressure towards the middle of the upcoming week will bring the return of unsettled weather.

SHORT TERM
(Today and tonight)
Issued at 233 AM PST Sat Dec 2 2023

Isolated showers are moving across the region this morning mainly across the North Bay, San Francisco Bay Area and down into the Santa Cruz Mountains. They may reach the Central Coast late this morning, but amounts are anticipated to be light. By this afternoon, the focus for additional precipitation will shift north across the North Bay.

Another cool afternoon is in store with temperatures struggle to warm much beyond the mid 60s across the interior, upper 50s elsewhere and upper 40s to lower 50s in the highest peaks.
Tonight, look for temperatures to cool into the lower 50s in the hills and around the San Francisco Bay Shoreline to the mid 40s elsewhere.

LONG TERM
(Sunday through Friday)
Issued at 233 AM PST Sat Dec 2 2023

A subtle warming trend will get underway on Sunday and then become more robust Monday into Tuesday. By Monday the interior is expected to reach the lower 70s and mid 70s by Tuesday. This warm up will be short-lived as the next mid/upper level trough approaches the West Coast.

Cooling will take place on Wednesday across the North Bay while mild conditions prevail over the Central Coast. This is when/where precipitation chances increase late Tuesday night into Wednesday.
Cool, unsettled weather will continue into Friday.

Once the precipitation tapers off on Friday the focus then turns to overnight lows. Longer range guidance suggests another round of chilly to cold night with frost/freeze conditions possible.

AVIATION
(06Z TAFS)
Issued at 945 PM PST Fri Dec 1 2023

Currently seeing light rain showers mosey their way across the Bay Area as the weak cold front passes by. The bulk of the shower activity will occur tomorrow during the day before tapering off in the late afternoon. All terminals will remain at or slightly above MVFR status throughout the TAF period, along with APC forecast to be in IFR territory between 12Z and 18Z and STS to remain in the LIFR/IFR category until 21Z. With the exception of APC and STS, there are no forecast visibility reductions to the terminals; however, if a shower were to develop over the terminal, visibilities may be briefly reduced. Best chances for showers are from SJC north.

Vicinity of SFO... Currently MVFR with showers approaching the terminal. There may be some more showers behind this initial round, but a majority of the shower activity is being reserved for tomorrow between 11Z and 00Z. There are no forecast reductions to visibility; however, if a shower were to develop over the terminal, visibilities may be briefly reduced. A clearing period between 00Z and 11Z Sunday is forecast to occur before the hint at another MVFR ceiling at the tail end of the TAF period. Winds tomorrow will be lighter than what they were today.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Currently VFR at both TAF sites; although, this will quickly turn to MVFR as the cloud shield of the weak cold front approaches. Showers were left out of the TAFs; however, it is not out of the realm of possibility that they may need to be included in later TAF issuances if this weak cold front proves to have more integrity to it than what we are seeing so far. MRY will see their MVFR ceiling after 10Z and retain it until about 19Z when there is a brief clearing period before getting it back at 2Z. There is now higher confidence that SNS will obtain an MVFR ceiling tonight by about 13Z and retain it until about 19Z. Both terminals

MARINE
(Today through Thursday)
Issued at 233 AM PST Sat Dec 2 2023

Gentle to moderate westerly breezes continue through the weekend with chance for rain across the northern waters. Northwest swell will build today into Sunday, resulting in elevated seas of 8 to 10 feet that will be hazardous to small craft across the northern waters. A series of larger northwest swells with a 16-20 second period will result in a continuation of elevated and hazardous seas through much of the upcoming week.

MTR WATCHES/WARNINGS/ADVISORIES
CA...None.
PZ...Small Craft Advisory until 3 AM PST early this morning for Pt Pinos to Pt Piedras Blancas 0-10 nm.

Small Craft Advisory from 9 AM this morning to 9 PM PST Sunday for Pt Arena to Pt Reyes 10-60 NM.
