Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries...
across the northern waters north of the golden gate, gentle to moderate southwesterly winds will continue through midweek as active weather continues across the pacific northwest. Moderate period northwest swell at 8 to 11 feet will persist into Monday. A series of long period northwest swells will propagate through the coastal waters starting Monday afternoon. As these swells build, elevated seas are expected to prevail for much of the upcoming week, resulting in hazardous conditions for small craft operators.

New SYNOPSIS, SHORT TERM, LONG TERM, MARINE

SYNOPSIS
Issued at 227 AM PST Sun Dec 3 2023

Cool, unsettled weather for Sunday followed by a short-lived warm-up early in the 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 227 AM PST Sun Dec 3 2023

Lingering light rain showers persist over the North Bay and San Francisco Bay Area this morning. Expecting the focus to shift northward throughout the day as a ridge of high pressure begins to build into the Central Coast.

Another cool afternoon is in store with temperatures struggle to warm much beyond the mid 60s across the interior, upper 50s elsewhere and 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
(Monday through Saturday)
Issued at 227 AM PST Sun Dec 3 2023

Expecting a warming and drying trend as we move into the upcoming week. On 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 and dips down into the North Bay by Tuesday night. Across the Central Coast, will hold on to one more warm day as the interior once again warms into the lower 70s on Wednesday.

Rain chances increase across the North Bay and San Francisco Bay Area Tuesday night and sweeps southward across the region.
However, this front is likely to "wash-out" on Wednesday with minimal rainfall over the Central Coast. Cool, unsettled conditions will persist 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 944 PM PST Sat Dec 2 2023

This forecast has proven to be very challenging as guidance has greatly differed from one hour to the next and clouds have scattered out that were forecast to stick around. APC will be in IFR territory between 11Z and 18Z and STS will be in LIFR territory between 8Z and 17Z. While OAK and SFO are in close proximity, it is looking like OAK will be receiving the brunt of things as they are forecast to stay MVFR between now and 20Z while SFO is now forecast to escape ceilings due to confidence being too low.

Vicinity of SFO... Currently VFR. Guidance has differed every hour on what the terminal is going to see in the way of MVFR ceilings.
There is now too low of confidence to include MVFR ceilings in the TAF as the consensus blend of high resolution models is now only highlighting it for the hour of 15Z and GFS LAMP has also significantly backed off with their probabilities with their timeframe potentially being 14Z-16Z. There are ceilings of about 2,000 feet upstream so it is not out of the realm of possibility that SFO may see something, but it is seeming more unlikely. Winds tomorrow will be breezy and onshore.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Currently VFR at MRY and MVFR at SNS.
Climatological models and the RAP are showing IFR ceilings for the terminals overnight while the consensus blend of high resolution models is keeping the IFR ceilings in the Central Monterey Bay Area.
That being said, confidence was not high enough to include IFR ceilings in the TAFs down here, but a low scattered group was included. Both terminals will experience E/SE winds overnight before switching to breezy onshore flow after the clearing of ceilings in the late morning.

MARINE
(Today through Friday)
Issued at 227 AM PST Sun Dec 3 2023

Across the northern waters north of the Golden Gate, gentle to moderate southwesterly winds will continue through midweek as active weather continues across the Pacific Northwest. Moderate period northwest swell at 8 to 11 feet will persist into Monday. A series of long period northwest swells will propagate through the coastal waters starting Monday afternoon. As these swells build, elevated seas are expected to prevail for much of the upcoming week, resulting in hazardous conditions for small craft operators.

MTR WATCHES/WARNINGS/ADVISORIES
CA...None.
PZ...Small Craft Advisory until 9 PM PST Monday for Pt Arena to Pt Reyes 10-60 NM.

Small Craft Advisory until 3 PM PST this afternoon for Pigeon Pt to Pt Pinos 10-60 NM.
