The upper-level pattern continues to be influenced by a ridge over the eastern Pacific. This maintains the above normal high temperatures observed over the last several days and today, leading to a moderate risk for heat related illnesses for the eastern areas. The Heat Advisory for the interior East Bay and South Bay will end this evening.
GOES-West visible satellite imagery shows the stratus continues to move back over the marine environment clearing most of the cities along the Pacific Coast. Otherwise sunny skies across the area. Stratus will continue to push westward for the next several hours eventually moving back inland this evening into the overnight period following typical June stratus patterns.
High tide flooding will continue to occur nightly along the Bayshore through the middle of next week. The combination of an upcoming new moon and lunar perigee on Sunday, about 7 inches of additional tidal anomaly from a combination of storm surge, thermal expansion of the Eastern Pacific, and about 2 inches inches of Sea Level Rise since the vertical datums were established in the 80s and 90s will add up to bring tides up to 2.0 feet above normal through early next week. While lower than the historic tidal flooding in January (peaked at 2.6 ft) the tides this weekend could end up being the highest observed in the Summer, beating the current record of 1.7 ft from July 2022.

A short-wave trough will cut along the outer periphery of the eastern Pacific ridge over the weekend. This will promote a cooling trend for interior locations into the second half of the weekend lessening the risk for heat related illnesses to minor. Coastal locations can expect the usual June stratus. While temperatures will return closer to middle- June climatology, the main hazards into early next week will be the southerly swell along the coast, plus coastal flooding associated with the high tides.

Southerly surge with coastal stratus and fog impacted Half Moon Bay and Monterey early this morning with reduced visibilities (IFR- LIFR). The fog and stratus also reached through the Golden Gate to the East Bay, but didn't impact visibilities. Inland conditions remained VFR. Diurnal surface heating has started to burn off some of the fog allowing for ceilings and visibilities to improve late this morning. As diurnal surface heating continues this afternoon ceilings and visibilities will continue to improve (back to MVFR and VFR) along the coastline. High resolution modeling continues to show coastal stratus and fog (IFR-LIFR) to redevelop tonight and tomorrow morning. Similar conditions from this morning are expected again tomorrow morning. Winds will follow similar patterns to the past 24 hours with speeds increasing to moderately breezy this afternoon, but diminishing around sunset.
Vicinity of SFO, High confidence of VFR conditions continuing into the overnight hours. Current NE winds will go NW'rly early this afternoon (~20Z). Wind speeds will increase into the middle teens this afternoon, but subside back below 10 kt around or shortly after sunset. Winds will then go westerly early tomorrow morning before going light and variable by the middle of tomorrow morning. IFR conditions are forecasted for tomorrow morning as radiative cooling may result in some patchy low stratus/fog developing.
SFO Bridge Approach, Similar to SFO.
Vicinity of SJC and OAK, Winds will predominately be out of the W/NW at OAK through the period. Winds at SJC will be out of the NW through this evening before going S/SE during the overnight hours. Wind speeds, at both sites, will be in the low to mid teens this afternoon through sunset, otherwise winds will be aob 8 kt. For OAK, morning stratus/fog (IFR) is expected to redevelop tonight and tomorrow morning, otherwise VFR conditions are expected. At SJC, VFR conditions are anticipated the whole period as morning stratus is not expected to impact the airport.
Monterey Bay Terminals, Similar conditions from the past 24 hours are expected for the next 24 hours. Stratus/fog from earlier this morning is starting to burn off with diurnal surface heating allowing for conditions to improve to MVFR-VFR. Stratus/fog (IFR/LIFR) is expected to redevelop and move inland tonight and tomorrow morning. Winds will be light and variable (but may tend to be more onshore winds) through the majority of the period. Westerly winds are expected to increase to 7-10 kt this afternoon, then subside around sunset.

A gentle southerly breeze and moderate to rough seas with a low south southwest swell persist across the coastal waters. The winds will remain fairly consistent through the weekend as the seas subside.

Long period southerly swell will continue through the weekend, 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. Hazardous beach conditions will expand to include Pacific coast beaches along the central coast and the Bay Area coast starting Saturday evening through Tuesday morning. Be sure 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, Coastal Flood Advisory until 3 AM PDT Wednesday for CAZ006-506- 508.
