Extensive midlevel cloudiness continuing to stream through from the south significantly interferes with ability to see extent of low cloudiness in IR fog product satellite imagery. That said, combination of surface observations and the few areas that can still be discerned from above indicates stratus coverage is now widespread around the bays and well into the coastal valleys. All terminals are presently reporting MVFR to IFR ceilings. Latest model output and statistical guidance indicates clearing on Saturday will be on the late side, as an upper level acts to deepen the marine layer and circulate in additional moisture.
Vicinity of SFO, MVFR CIGs now well-established, and expect will persist through Saturday morning. Clearing looks to be delayed until at least around midday and potentially even a bit later. Seasonally typically breezy west winds will develop during the afternoon.
SFO Bridge Approach, Similar to SFO.
Monterey Bay Terminals, MVFR CIGs prevail at both KMRY and KSNS, and expect will persist through Saturday morning, possibly lowering to IFR at KMRY around sunrise. Clearing looks to be delayed until midday to early afternoon. Seasonally typical moderate onshore winds are expected to develop during the afternoon.
