Area Forecast Discussion National Weather Service San Francisco CA 1040 PM PDT Wed May 15 2024

New AVIATION, MARINE

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.

UPDATE
Issued at 903 PM PDT Wed May 15 2024

Low level marine stratus this evening has begun filling farther inland as expected and will persist through the overnight hours, with patchy fog and periods of drizzle as well. Early morning low temperatures will remain similar to the past few days, dropping into the upper 40s to mid 50s area wide. Highs tomorrow will once again be in the low 60's near the coast, then into the 70's and 80's the farther you go inland during the afternoon. Onshore flow will result in breezy winds across some of the gaps and passes, especially the Salinas Valley where gusts are expected to reach 30 MPH at times in the afternoon.

SHORT TERM
(This evening through Thursday)
Issued at 1232 PM PDT Wed May 15 2024

The stratus is clearing on schedule and should return this evening. The marine layer is currently around 1500-2000 ft deep as identified by a sharp low level inversion on the 12Z sounding and current observations from area profilers. NAM point soundings suggests the marine layer will compress to around 800 ft over the next 18 hours. This will cause a lower cloud deck Thursday, with more areas impacted by mist and fog. It will also limit the extent of the marine layer, keeping more inland areas in the sun and the warmer continental air mass. Otherwise, the weather pattern is pretty stable with mild temperatures and a weak pressure gradient producing light to gentle winds.

LONG TERM
(Thursday night through next Thursday)
Issued at 1232 PM PDT Wed May 15 2024

The current pattern will remain fairly stable through Sunday. Low clouds in the morning along the coast and adjacent valleys will clear by mid-day. High temperatures will be stuck in the 60s for areas in the marine layer, and in the 80s for the warmest inland valleys. Lows will mostly be in the 50s. By early next week, the global models agree that the jet stream, which has been running E-W across the PNW, will become meridional, with a long wave trough taking aim at California. This trough pattern will persist through next week, bringing a few weak cold fronts, some cooler weather, periods of stronger NW winds, and even the chance for some very light rain, although the air mass looks pretty dry.

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 Thursday to 3 AM PDT Friday for Pt Arena to Pt Reyes 10-60 NM.
