Synopsis for the central california coast and bays including the Monterey bay - Greater farallones - .and cordell bank national marine sanctuaries - .
moderate to fresh northwesterly winds continue through the middle of the work week before diminishing to gentle to moderate beginning Wednesday. Occasional near gale force to gale force gusts are possible across portions of the northern outer waters overnight Monday into Tuesday morning. Winds will become more west to southwesterly and gusts are expected to strengthen across the northern outer waters heading into the late week and weekend. Overcast conditions and widespread stratus continue across the coastal waters as surface high pressure builds. Significant wave heights across the central and northern outer waters will build to 10-14 feet by mid- week before seas diminish by late week.

Area Forecast Discussion National Weather Service San Francisco CA 1218 AM PDT Tue May 14 2024

New SHORT TERM, LONG TERM

SYNOPSIS
Issued at 1217 PM PDT Mon May 13 2024

Relatively quiet pattern persists through the forecast period with morning marine stratus and clear skies elsewhere. Inland temperatures warm into the 70s and 80s each afternoon with a persistent marine layer keeping coastal highs in the 60s.

SHORT TERM
(Today and tonight)
Issued at 1217 AM PDT Tue May 14 2024

Low pressure aloft will migrate from SoCal into the Desert Southwest as an expansive high pressure ridge encompasses much of the northeast Pacific. Our area will remain on the eastern periphery of the upper ridge with minimal changes to our sensible weather. A relatively deep marine layer around 1.5-2 kft was evident via area profilers early this morning, with low stratus clouds spilling inland across most of the area. Expect the top of the marine layer inversion to remain relatively steady this morning before compressing slightly as high pressure gains a bit more influence.
However despite these modulations it's mostly a rinse and repeat forecast. Cloudy skies for the coast and marine influenced valleys overnight with a gradual clearing towards the beaches during the late morning to early afternoon hours. High temperatures will range from the 60s along the coast and bays to the upper 70s and 80s for the warmest inland locations. As mentioned in the previous discussion some of the model temperature guidance seems a touch too warm when compared to observations over the past few days, so followed the previous forecast philosophy of trending slightly cooler for readings in areas which are likely to see a stronger marine influence. Otherwise not much else to add with overnight lows remaining seasonal in the upper 40s and 50s.

LONG TERM
(Wednesday through Monday)
Issued at 1217 AM PDT Tue May 14 2024

The upper level ridge will gain slight prominence through midweek, however we will remain along its periphery with a minimal increase in temperatures inland. Readings will range from the 60s along the coast to the upper 80s for the warmest inland valleys. A few hot spots may crack the 90 degree mark. Lows will be mostly in the 50s.
The daily ebb and flow of coastal clouds will continue, with coverage spreading inland each night with a gradual retreat towards the coast by afternoon. The upper level pattern may transition more towards troughing by early next week but dry weather still looks to be the most probable forecast outcome.

AVIATION
(06Z TAFS)
Issued at 1038 PM PDT Mon May 13 2024

Currently seeing a mix of VFR-LIFR at the terminals. The marine layer continues to be allowed to deepen thanks to a weak upper- level low with the depth somewhere in the 1,500-1,800 foot range.
This deeper marine layer will allow for stratus to penetrate further inland and impact all terminals within the TAF period.
Highest confidence is in IFR-low-end MVFR at LVK, MRY, SFO, SJC, and SNS and LIFR at APC and STS. OAK has the greatest uncertainty as to whether or not the ceiling will be IFR or LIFR; while not high, highest confidence is in IFR based on persistence and a deepening marine layer, but the terminal's proximity to APC could allow for the terminal to go LIFR. Widespread VFR and breezy onshore flow will prevail by tomorrow afternoon.

Vicinity of SFO...Currently VFR with breezy westerly flow. An IFR- low-end MVFR ceiling will impact the terminal again overnight with conditions improving to VFR by late-morning. Winds will remain onshore and breezy through the TAF period with gusts up to 25 knots to be expected tomorrow afternoon.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Currently IFR with westerly flow at MRY and MVFR with northwesterly flow at SNS. Confidence is highest in ceilings remaining IFR-low-end MVFR overnight. VFR to prevail by the afternoon. Winds will remain onshore through the TAF period. MRY quickly deteriorates again tomorrow evening with SNS looking to deteriorate into the next TAF cycle.

MARINE
(Tonight through next Sunday)
Issued at 1038 PM PDT Mon May 13 2024

Moderate to fresh northwesterly winds continue through the middle of the work week before diminishing to gentle to moderate beginning Wednesday. Occasional near gale force to gale force gusts are possible across portions of the northern outer waters overnight Monday into Tuesday morning. Winds will become more west to southwesterly and gusts are expected to strengthen across the northern outer waters heading into the late week and weekend.
Overcast conditions and widespread stratus continue across the coastal waters as surface high pressure builds. Significant wave heights across the central and northern outer waters will build to 10-14 feet by mid- week before seas diminish by late week.

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