Coastal stratus continues to retreat to the coast early this afternoon with mid-to-high level clouds also exiting to the east. Temperatures this afternoon are forecast to range from the upper 50s to lower 60s along the immediate coastline, middle 60s to middle 70s near the bays, middle 60s to lower 80s in the inland valleys, and upper 60s to lower 90s in the warmest interior spots. These temperatures are generally up to 10 degrees below seasonal averages as a shortwave through continues to impact the region. Breezy onshore winds are also forecast to develop this afternoon with gusts up to 20 to 25 mph through gaps, passes, and the Salinas Valley.
Once again, stratus will return to the coast late this afternoon/early evening and return into the inland valleys overnight through Monday morning before retreating back to the coast by Monday afternoon. Troughing aloft will maintain cooler conditions once again on Monday with similar afternoon temperatures as today. A few passing high clouds are also likely. Similar stratus pattern is expected once again Monday night into Tuesday morning.

A gradual warming trend will persist through the second half of the week as high pressure strengthens over the Desert Southwest. However, persistent onshore flow will maintain a modest marine layer and keep conditions near the coast cooler than inland areas. Overall, HeatRisk look to remain in the Minor category with isolated pockets of Moderate in the warmest interior locations.

The marine layer is about 1,500 feet deep and stratus will begin pushing inland over the next six hours. With a similar pattern as yesterday, the TAFs relied heavily on the persistence forecast for ceiling arrival and clearing times.
Vicinity of SFO, The Peninsula mountains are doing there job to keep the terminal clear for now. Stratus will likely fill in through the Golden Gate, impacting the East Bay this evening before wrapping around to reach SFO later tonight. The exact timing is tricky, but expect MVFR ceilings to arrive sometime between 06Z and 12Z.
SFO Bridge Approach, Similar to SFO. Clouds will likely impact the approach 1-2 hours before reaching the terminal tonight.
Monterey Bay Terminals, MRY already has MVFR ceilings and will keep them through the night. They are knocking on the door at SNS too.

Gentle to moderate northwest breezes persist through Monday as the cold front continues its push eastward. Winds increase to a fresh to strong breeze Monday night with near gale force gusts possible Tuesday late afternoon. As a result, moderate seas begin to build across the outer coastal waters followed by the inner coastal waters.
Ca, None. PZ, Small Craft Advisory from 9 PM Monday to 3 PM PDT Tuesday for Pt Pinos to Pt Piedras Blancas 0-10 nm.
