Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries...
light winds continue across the waters, except near point sur where breezy northerly winds will persist until Tuesday morning. Possibly another round of dense fog will be over the san francisco bay, san pablo bay, and the delta early Tuesday morning and will diminish towards the early afternoon. Elevated seas between 12-17 feet waves will persist for much of the week as a series of large, long period northwest swells propagate through the waters, resulting in hazardous conditions for small craft operators. Chances of rain over the waters will begin Tuesday night through the end of the work week.

SYNOPSIS
Issued at 232 AM PST Mon Dec 4 2023
A short-lived warming trend will begin today and continue into Tuesday. An approaching trough of low pressure will bring the return to unsettled weather Tuesday night into Wednesday that will last into late week.
SHORT TERM
(This evening through Tuesday)
Issued at 130 PM PST Mon Dec 4 2023
Pretty interesting first half of the day with regards to dense fog. Building high pressure, lack of strong surface flow, and ample low level moisture led to a dense fog event this morning.
Numerous locations around the Bay Area reported dense fog. Given the time of year and lower sun angle fog lingered well into the afternoon. In fact, KOAK continues to show fog with vis less than one mile. Pretty impressive to have fog this late in the day for early December, tend to see this scenario later in December.
Outside of the lingering fog sunny skies prevail with mild temperatures in the 60s (warmer than yesterday at this time).
Biggest weather impact in the short term will be dense fog. Hi-res models continue to advertise another fog event tonight. Ensemble probabilistic guidance gives about a 50-70% chance for widespread vis less than one mile. Fog development/coverage would be greatest over the N Bay Valleys, SF Bay/West Delta, S Bay Valleys, and pockets of the E Bay Valleys. Will have to monitor close, but another Dense Fog Advisory may be needed.
High pressure is still on track to bring another mild day on Tuesday with highs in the 60s to mid 70s. Interior valleys in the mid 70s would be running about 5-10 degrees above normal for early December.
LONG TERM
(Tuesday night through next Sunday)
Issued at 215 PM PST Mon Dec 4 2023
Still looking at a pattern shift Tuesday night into Wednesday as high pressure aloft weakens and a cold front approaches from the NW. Latest deterministic guidance has slowed the next front Tuesday night, but ensemble guidance less so much. Regardless of this trend, will still have a few showers for the North Bay Tuesday night. A cold front will sweep through the Bay Area and Central Coast during the day. As the front moves southward it will lose steam and diminish. As a result, the North Bay could see a brief period of light to moderate rain on Wednesday, but other areas are more likely to see showers and/or light rain. Precip will gradually taper off from N to S. The temporary "break" in precip will be short-lived as another cold front approaches the region Wednesday night into Thursday. This second front looks less wet than the first front with a more showery regime. Some additional rainfall will be possible, but not a lot of additional accumulation. One thing the second front will do is bring in colder air. Snow levels will drop through the day on Thursday and high elevation snow showers will be possible on Thursday and Friday. No notable changes to the overall rainfall amounts: Tuesday night through Thursday evening: 0.25- 0.75" in the North Bay, 0.05-0.25" elsewhere, to barely a trace interior Monterey/San Benito and Santa Clara Valley.
Once precip ends Thursday evening the next weather impact remains on track with colder overnight lows. Clearing skies Thursday night and Friday night and a colder airmass will set the stage for chilly to cold temps. Decent confidence (still 40-60%)for freezing temperatures over the interior N Bay and S Monterey/San Benito. If the forecast holds a mix of frost and freeze products will be needed.
AVIATION
(00Z TAFS)
Issued at 329 PM PST Mon Dec 4 2023
VFR through early this evening, then IFR-LIFR is likely to return for the Bay Area terminals overnight into mid Tuesday morning.
The North Bay terminals should experience this first around 04-06Z, with conditions deteriorating across the remainder of the Bay Area terminals between 07-12Z. A consensus of the high resolution forecast models suggest high confidence in this scenario, albeit with slight differences in duration and exact visibility values. Regardless, plan on an extended period of sub- VFR later tonight into Tuesday morning. Conditions generally improving 17-19Z on Tuesday, with a lower potential (10-15%) that sub-VFR conditions last until 20-21Z (such as what occurred at KOAK today). Prevailing VFR for the remainder of the TAF period with light and variable winds.
Vicinity of SFO...VFR through mid evening with light and variable winds. High confidence (60-70%) in sub-VFR conditions late tonight into mid Tuesday morning. Low to medium confidence (30-50%) in exact timing and visibility values. Overnight amendments are possible. Return to VFR most likely around 18-19Z, however low potential (10-15%) that sub-VFR conditions linger until 20-21Z. VFR should prevail for the remainder of the TAF period.
SFO Bridge Approach...Similar to SFO.
Monterey Bay Terminals...VFR with light winds. Some 5-6SM BR possible around KSNS late tonight into early Tuesday morning.
MARINE
(Today through Saturday)
Issued at 848 AM PST Mon Dec 4 2023
Light winds currently across the coastal waters, but northerly winds will become breezy again this afternoon near Point Sur while gentle southerly winds persist across the northern waters. Patchy dense fog will be over the San Francisco Bay, San Pablo Bay, and the Delta early this morning and will diminish towards the early afternoon. Elevated seas will persist for much of the week as a series of large, long period northwest swells propagate through the waters, resulting in hazardous conditions for small craft operators. Widespread rain chances return midweek.
BEACHES
Issued at 325 AM PST Mon Dec 4 2023
A long period northwest swell will build into the coastal waters this afternoon, resulting in large, unexpected waves that can sweep across the beach without warning through Tuesday. Sneaker waves can sweep people and pets into the sea from rocks, jetties, and beaches as well as move large objects such as logs, crushing anyone caught underneath. Northwest-facing beaches are most at risk for sneaker waves today into tomorrow. Additional long- period swells are expected to move through the waters through midweek, resulting in potentially another round of sneaker waver risks. As these swells build into midweek, large wave heights are forecasted which may result in the issuance of a High Surf Advisory. Be sure to stay updated with the forecast for any beach hazard updates this week.
