PZZ500 204 Am Pdt Thu May 16 2024
Synopsis for the central california coast and bays including the Monterey bay - Greater farallones - .and cordell bank national marine sanctuaries - .
surface high pressure over the eastern pacific ocean will ever so slightly begin to build and move east today. As a result, the pressure gradient will tighten and northwesterly winds will increase, particularly over the northernmost zones and outer waters. Significant wave heights will build through early next week.

Area Forecast Discussion National Weather Service San Francisco CA 1217 AM PDT Thu May 16 2024

New SHORT TERM, LONG TERM

SYNOPSIS
Issued at 1232 PM PDT Wed May 15 2024

Quiet weather will continue with a persistent marine layer through the forecast period. Morning clouds and mist will clear in the afternoon. Despite the clearing, coastal areas will remain in the cool marine air, keeping highs in the 60s. Inland and high elevation areas will reach the 70s and 80s each afternoon.

SHORT TERM
(Today and tonight)
Issued at 1217 AM PDT Thu May 16 2024

High pressure aloft remains the predominant weather feature over the northeast Pacific as weak troughing prevails across the Desert Southwest. We remain on the eastern periphery of the ridge, with minimal influence so far. In fact, the marine layer remains relatively stable from where it was 24 hours ago with a depth of 1.5- 2 kft. Some patchy drizzle was observed around the Monterey Bay area within the past few hours as well. Expect the upper ridge location to remain fairly similar for the remainder of the short term forecast period with little overall change. It's possible that the marine layer may compress a little given the nearby ridge, but so far it's remained fairly consistent in depth. Otherwise it's another day of low clouds clearing to the coast during the afternoon before returning this evening and overnight. Highs today will remain seasonally cool and range from the upper 50s along the coast to the lower-mid 80s inland.

LONG TERM
(Friday through Wednesday)
Issued at 1217 AM PDT Thu May 16 2024

Expect a transition towards west coast troughing by early next week.
This pattern is supportive of weak cold frontal passages, cooler temperatures, and breezy northwest winds. Coastal drizzle may become a bit more prominent at times as well. High temperatures will be mostly in the 60s and 70s, with the warmest inland areas perhaps breaking 80 degrees. But by and large readings will remain a touch below seasonal averages.

AVIATION
(06Z TAFS)
Issued at 1037 PM PDT Wed May 15 2024

Currently a mix of VFR-LIFR at the terminals. As the marine layer continues to slightly compress, IFR-LIFR conditions are to be expected at all terminals overnight with the exception of SFO which is expected to at least get a low-end MVFR ceiling. Widespread VFR and onshore flow will prevail by tomorrow afternoon.

Vicinity of SFO...Currently VFR with westerly flow. Confidence is high that the terminal will get a ceiling overnight with the uncertainty lying on whether it will be low-end MVFR like what has been observed the last two nights or if it will be affected by the compression of the marine layer and dip to IFR. Either way, VFR to prevail by late morning tomorrow. Winds become more southwesterly through the TAF period.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Currently LIFR with westerly flow at MRY and IFR with northwesterly flow at SNS. SNS is expected to further deteriorate to LIFR with both terminals VFR by tomorrow afternoon.
IFR conditions are slated to return to both terminals by tomorrow night. Winds will remain onshore through the TAF period.

MARINE
(Tonight through next Tuesday)
Issued at 1037 PM PDT Wed May 15 2024

Moderate to fresh northwesterly winds prevail as surface high pressure over the Eastern Pacific continues to weaken. Seas will also continue to abate through Thursday. By Friday the surface high strengthens and moves eastward, strengthening northwesterly breezes and building wave heights through the weekend and into next week.

MTR WATCHES/WARNINGS/ADVISORIES
CA...None.
PZ...Small Craft Advisory from 9 AM this morning to 3 AM PDT Saturday for Pt Arena to Pt Reyes 10-60 NM.
