Synopsis for the central california coast and bays including the Monterey bay - Greater farallones - .and cordell bank national marine sanctuaries - .
moderate northwesterly winds persist through Friday morning with occasional fresh to strong gusts throughout portions of the coastal waters. Winds strengthen to become strong and gusty into Friday afternoon with gale-force gusts likely near the big sur coast. These strong and gusty northwesterly winds last through the weekend and into at least the early portion of next week, bringing hazardous conditions for small craft. Moderate period northwest swell will continue to move through the waters this weekend, with a new longer period northwest swell train entering the waters Sunday. Light, long period southerly swell continues through end of forecast period.

New AVIATION, MARINE
SYNOPSIS
Issued at 1201 AM PDT Thu Apr 25 2024
Cool temperatures will continue today. A cold front will bring a chance for light rain beginning tonight, with strong winds Friday night. Increasing sunshine will kick off a warming trend Sat-Tue.
SHORT TERM
(Today and tonight)
Issued at 1201 AM PDT Thu Apr 25 2024
A coastal surface trough will continue to weaken and move inland, allowing a low-amplitude ridge to build. This will cause the marine layer to compress to about 1,500 ft. Compared to the 4,000 ft deep marine layer observed Wednesday, the low overcast today will be more limited to the coast and adjacent low valleys. The standard NW flow will also return as the trough weakens. The cool temperatures will continue, with highs generally in the 60s. This ridge pattern will be short lived as a cold front moves through on Friday.
LONG TERM
(Friday through Wednesday)
Issued at 1201 AM PDT Thu Apr 25 2024
Some light rain is possible starting ahead of the cold front Thursday night, with low PoPs lasting though the day Friday.
22/26 members of the SREF have some precipitation falling at SFO between Thursday night and Friday, but only 4 of them are above 0.05" of accumulation, and none of those are above 0.1". Similar results are found throughout the Bay Area, with slightly more bullish results along the Central Coast. As such, I have increased the NBM PoPs to at least 15% to ensure a slight chance of rain is mentioned, but did not increase the QPF from the WPC guidance, which is near zero. There's a decent chance some rain falls late Thursday-Friday, but it will be light.
The bigger impact will be from strong NW winds behind the cold front. 24 hours ago, it looked like a slam dunk wind advisory along the coast, but the models have backed off since then. NBM is on the high side of the guidance, but only shows a slight chance of exceeding 40 mph gusts along the coast on Friday night. The timing of the strongest winds has also shifted from Friday afternoon to overnight Friday. Based on this, and the fact that other deterministic models are even less aggressive, we are not hoisting a wind advisory at this time. That being said, there will be plenty of gusts above 30 mph on Friday and Saturday with some minor impacts expected.
The weekend will feature clearing skies and slightly warmer temperatures, although Saturday will still be breezy. The gradual warm-up will continue through early next week, as the region returns to seasonal temperatures under mostly clear skies. The next threat of rain arrives late next week.
AVIATION
(12Z TAFS)
Issued at 457 AM PDT Thu Apr 25 2024
MVFR conditions persist through the late morning for most terminals with westerly winds steadily increasing through the day. Most terminals will see CIGs lift to VFR conditions late in the morning of Thursday, with winds steadily increasing out of the west to become moderate to strong, and gusting 20-25+ knots well into the evening. KSFO is likely to see the strongest gusts nearing 30 knots.
Aside from strong winds and gusty conditions, models continue to be in good agreement that stratus will push inland in the early evening near 00Z-02Z Friday. Strong onshore winds help advect these low clouds inland, bringing widespread MVFR conditions once more that are expected to last through the end of the TAF period for most terminals.
Vicinity of SFO... Expect MVFR CIGs to last into the late morning before brief lifting to VFR briefly for a few hours into the afternoon. Some models seem to suggest KSFO remaining MVFR through the TAF period, though highest confidence is in CIGs improving to VFR conditions beginning in the late morning and lasting through the late afternoon. Despite improvement to VFR conditions, low to mid level clouds will continue to be present throughout the duration of the TAF period. Winds will begin to strengthen and gust 25+ knots out of the west this morning, with winds continually strengthening into the early afternoon. MVFR CIGs will return in the early evening, as stratus is ushered in by strong westerly winds. MVFR then lasts well beyond the end of the TAF period with winds slowly decreasing into the late night to around 12 knots.
SFO Bridge Approach...Similar to SFO.
Monterey Bay Terminals...KMRY improves from IFR to MVFR later this morning as CIGs begin to lift beyond sunrise. Coastal drizzle that has impacted terminals overnight will also begin to cease beyond sunrise. Stratus will continue to shroud area terminals through the day today with no improvement to VFR expected. Chances of VFR are only in the 30-40% range, therefore have gone with MVFR prevailing through the entire TAF period for KMRY, and only brief clearing to SCT for KSNS. However, confidence in KSNS clearing to VFR is low.
Winds onshore, moderate, and gusting to around 20-25 knots beginning in the late morning and continuing through the late night tonight.
Stratus and MVFR CIGs last well into the morning of Friday, with coastal drizzle making a return.

(Today through Tuesday)

Moderate northwesterly winds persist through Friday morning with occasional fresh to strong gusts throughout portions of the coastal waters. Winds strengthen to become strong and gusty into Friday afternoon with gale-force gusts likely near the Big Sur coast. These strong and gusty northwesterly winds last through the weekend and into at least the early portion of next week, bringing hazardous conditions for small craft. Moderate period northwest swell will continue to move through the waters this weekend, with a new longer period northwest swell train entering the waters Sunday.
