The marine layer is roughly 1000 to 1500 ft with stratus building back inland early this morning, although slightly less inland push than yesterday morning.
The marine layer will continue to slowly compress through the short term with a slow reduction in stratus and a warming and dry trend through midweek. The more compressed marine layer will allow patchy fog to develop along the coast and in wind-sheltered valleys this morning and again tonight/Wednesday morning.
While a warming trend is expected through Wednesday, have lowered highs temps a couple of degrees as the overall ridging pattern is trending weaker. As a result, the threat of Moderate HeatRisk conditions for portions of the South and East Bay looks to have ended Highs will climb into the 80s for inland areas, while far interior areas will reach the 90s. Continued cool along with coast with highs in the upper 50s to lower 60s, with 70s for near- coast areas.
We continue to highlight a long-period southerly swell that will bring a risk for sneaker waves and strong rip currents, with a Beach Hazards Statement out through Wednesday. If heading to the coast, stay back from the beach, and away from jetties, piers, beachside rocks, and other infrastructure near the water. Never turn your back to the ocean!

An upper-level trough will approach the West Coast by Thursday. Temperatures will still be similar to Wednesday, with a few spots seeing their afternoon highs slightly lower than Wednesday, mainly south of the Bay Area. The cooling trend will become more pronounced Friday into Saturday as upper-level troughing deepens over the region, leading to a resurgence of the marine layer and breezy to gusty winds. Temps will be the coolest on Saturday with highs generally in the 60s and 70s. Patchy drizzle will could also develop along the coast. Onshore winds will increase, peaking Friday and Saturday with a frontal passage, with gusts 30 to 40+ mph across ridgelines and through gaps and passes. A slight warming trend is still favored for Sunday into early next week, but overall confidence remains low as there is quite a large spread in model guidance in regards to the progression of the upper trough to the east and ridging trying to creep back in from the eastern Pacific.

MVFR/IFR, locally LIFR cigs will continue through morning clearing from inland areas to the coast 16-19z, with BKN cigs clinging to the beaches through the afternoon hours. Typical diurnal winds expected this afternoon, easing through the evening. Similar cloud bases returning to most areas this evening through Wednesday morning.
Vicinity of SFO, MVFR/IFR conditions this morning, becoming VFR after 18z with high confidence. Winds increasing out of the NW/W during the afternoon hours with gusts near 25 kts at times. MVFR conditions returning by 04z Wed, becoming IFR shortly thereafter. VFR prevails once again mid Wed morning/afternoon.
SFO Bridge Approach, Similar to SFO. Increased chance of BKN cigs to linger in the afternoon hours.
Vicinity of SJC and OAK, For SJC, MVFR this morning, becoming VFR after 17z with high confidence. MVFR cigs returning 06-08z with moderate to high confidence in timing. For OAK, less confidence on VFR timing later this morning, most likely after 18z. MVFR/IFR conditions after 03z with moderate timing confidence. Typical diurnal winds for both sites 10-15 kts in afternoon.
Monterey Bay Terminals, MVFR/IFR conditions improving after 18z. Persistent NW flow aloft may only bring intermittent scattering to MRY like yesterday afternoon. MVFR cigs returning after 01z Wed, becoming IFR shortly thereafter. Typical diurnal W/NW winds 5-15 kts.

Gentle to moderate winds will persist through mid week. Fresh to strong breezes resume over the coastal waters mid to late week. Seas moderate through Wednesday with long period southwest swell persisting through the extended forecast.

Long period southerly swell at around 14 to 16 seconds will increase to 17 to 19 seconds by the middle of the week as energetic storms in the Southern Hemisphere continue to affect the California coast, especially for south and southwest facing beaches. Hazardous beach conditions are advertised, specifically for moderate to steeply sloped beaches along the Pacific Coast of the North Bay, San Mateo, Santa Cruz counties. A Beach Hazards Statement for Pacific Coast beaches continues through Wednesday afternoon. Be sure to check beach conditions before you head out. Sneaker waves will run up the beach much farther than other waves, potentially catching beachgoers by surprise and resulting in people being swept into the water. Rip currents are strong enough to pull the strongest swimmers away from shore. Swim near a lifeguard if possible. Stay back from the beach, and away from jetties, piers, beachside rocks, and other infrastructure near the water. Never turn your back to the ocean!
Ca, Beach Hazards Statement through Wednesday afternoon for CAZ006- 505-509-529-530.
PZ, None.
