Synopsis for the central california coast and bays including the Monterey bay - Greater farallones - .and cordell bank national marine sanctuaries - .
overcast conditions continue over the majority of the coastline with low level stratus coverage to become more widespread overnight. Potential for patchy fog, patchy haze, and light drizzle returns tonight and continues through tomorrow morning which may result in temporarily reduced visibilities. Northerly to northwesterly flow continues over the coastal waters with widespread fresh to strong gusts conditions spreading north to south over the waters beginning Saturday. Significant wave heights gradually build over the outer coastal waters moving into the weekend and inner coastal waters by the late weekend. Hazardous conditions for small crafts continue over the outer coastal waters with conditions over the inner coastal waters becoming hazardous by late weekend.

New AVIATION, MARINE

SYNOPSIS
Issued at 336 AM PDT Fri Jun 7 2024

Cooling continues through the weekend, with temperatures largely near seasonal averages. Warming returns early next week as ridging redevelops, though not expecting temperatures to reach as high as they did the last few days.

SHORT TERM
(This evening through Saturday)
Issued at 218 PM PDT Fri Jun 7 2024

Low stratus clouds continue to linger along the coastline with some sunshine occasionally breaking through this afternoon. Clear skies farther inland have allowed temperatures to climb into the 70s and 80s, with some higher elevations to the east and south in the 90s with breezy west/southwest surface winds. An upper level ridge axis will shift east across our area for the remainder of today and tonight while an upper trough deepens over the open water to our west. The upper trough will produce increasing mid/high clouds tomorrow afternoon helping to cool temperatures a few degrees inland, while low stratus clouds persist keeping temperatures along the coast in the 60s. The slow moving upper trough will result in similar conditions on Sunday.

LONG TERM
(Saturday night through next Thursday)
Issued at 218 PM PDT Fri Jun 7 2024

The aforementioned slow moving upper trough eventually shifts east by early Monday morning, while a cutoff low splits off from the southern portion of the trough over the southeast Pacific. There's some uncertainty in the synoptic longwave pattern across our area, depending on how the cutoff low evolves over the weekend. The warming trend for the middle of next week and beyond remains in the forecast but the max temperatures have trended slightly lower. The warmer temperatures peak on Wednesday, with a gradual cooling trend for late in the week as the cutoff low begins to move onshore across SOCAL.

AVIATION
(00Z TAFS)
Issued at 456 PM PDT Fri Jun 7 2024

Currently VFR at all stations except SNS. VFR will transition to MVFR-LIFR heading into the late evening as a deeper marine layer allows for stratus to intrude farther inland. Confidence is moderate to high that stratus will reach STS, APC, OAK, SFO, MRY, and SNS.
There is more uncertainty on stratus reaching SJC and LVK with models lacking a consensus on inland stratus extent. Forecast RH values remain fairly high at both airports so leaning towards stratus reaching them but, particularly for LVK, stratus may only be present for a few hours mid-morning. Some potential for patchy fog to develop across the North Bay and Central Coast which may cause visibility and ceiling heights to dip - will continue to monitor and revise TAFs as needed.

Vicinity of SFO...VFR transitioning to MVFR overnight. Stratus is expected to return this evening around 08Z with a few models indicating an earlier return between 06-07Z. Moderate confidence that ceiling heights will stay MVFR. Main change to SFO TAF was pushing up stratus departure time tomorrow morning to 19Z from 21Z.
RH values decrease more significantly and winds pick up beginning at 18Z which should contribute to stratus dissipation. A few models lean on stratus dissipation closer to 18Z but confidence is low at this time. Moderate onshore flow continues through the day before weakening slightly overnight. Gusty conditions look to return tomorrow afternoon with gusts up to 25 knots expected.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...MVFR transitioning to IFR-LIFR at SNS and VFR transitioning to MVFR-LIFR at MRY. Stratus return timing for MRY is a bit tricky tonight. Visible satellite shows (as of 00Z) stratus receding slightly along the Monterey Bay coastline which may impact the 01Z ceiling arrival time at MRY. For now, continuing the 01Z arrival time at MRY as stratus coverage should grow as the sun goes down but it may need to be pushed back closer to 02Z. Ceiling heights at MRY and SNS will decrease to LIFR overnight with some potential for fog to develop early to mid-morning (12Z - 16Z time frame) which may cause decreased visibility. Moderate, gusty onshore winds continue through the evening before weakening overnight.
Stronger winds return by late tomorrow morning with gusts up to 20 knots possible.

MARINE
(Tonight through next Wednesday)
Issued at 456 PM PDT Fri Jun 7 2024

Overcast conditions continue over the majority of the coastline with low level stratus coverage to become more widespread overnight. Potential for patchy fog, patchy haze, and light drizzle returns tonight and continues through tomorrow morning which may result in temporarily reduced visibilities. Northerly to northwesterly flow continues over the coastal waters with widespread fresh to strong gusts conditions spreading north to south over the waters beginning Saturday. Significant wave heights gradually build over the outer coastal waters moving into the weekend and inner coastal waters by the late weekend.
Hazardous conditions for small crafts continue over the outer coastal waters with conditions over the inner coastal waters becoming hazardous by late weekend.
