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 will continue today and through the weekend with chances 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.

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.

UPDATE
Issued at 842 AM PST Sat Dec 2 2023

Dreary start to your Saturday with a mix of sun/clouds, cool/damp conditions and scattered showers. KMUX radar, located in the Santa Cruz Mts, continues to show widely scattered showers moving through the Bay Area and Central Coast. Rainfall amounts over the last six hours range greatly - trace to no precip South Bay southward to a few hundredths Santa Cruz Mts/San Francisco Bay northward. Current forecast calls for lingering showers through out the day and see no reason to update the forecast. While today will not be a wash out, hit or miss showers will be possible.
Additional rainfall today will be on par with the last six hours - a few hundredths to maybe a tenth with a stronger showers.

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
(18Z TAFS)
Issued at 1030 AM PST Sat Dec 2 2023

Mix of MVFR, IFR, and LIFR conditions throughout the area. Radar shows light scattered showers moving through the Bay Area with KSTS and KOAK currently reporting light rain. Unsettled conditions will continue through the afternoon with rain chances diminishing by the late afternoon for most stations. Temporary decreases to visibility and CIG height are possible if showers cross directly over the airport. Across the North Bay, light rain showers remain possible through early Sunday with ceilings briefly transitioning from IFR to MVFR during the afternoon before returning to IFR overnight. MVFR conditions throughout the Bay Area and the Central Coast are expected to transition to VFR conditions during the late morning/early afternoon before returning to MVFR overnight.

Vicinity of SFO...MVFR conditions. Intermittent light rain showers are expected to continue through the early afternoon as radar shows scattered showers approaching the SF Peninsula. Moderate confidence VFR conditions will return by late afternoon between 23-00Z with a few models suggesting an earlier return around 21Z. MVFR conditions will return overnight between 05-06Z. Winds will remain relatively light (<10 kts) and will transition from the SE to the SW by the afternoon.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...MVFR conditions transitioning to VFR during the afternoon. Scattered showers have mostly moved out of the Central Coast with VFR conditions to return between 19-20Z. Winds will stay fairly light and transition from SE to NW by early afternoon. MVFR ceilings return by late evening and will remain until 17/18Z tomorrow morning.
