Stratus has retreated to the coast as of early afternoon with mostly sunny skies across the interior. Thus, temperatures inland temperatures will warm into the 70s to mid 80s and the lower 90s across the far interior. Meanwhile, persistent onshore flow and the marine layer will maintain cooler conditions near the coast, generally reaching into the 60s.
The marine layer is likely to deepen overnight to around 2000 feet and with an increased potential for coastal drizzle tonight and into midmorning on Monday. Expecting a slower clearing of stratus Monday morning as troughing off of the Pacific Northwest coast develops and deepens. As such, afternoon maximum temperatures will be 5 to 15 degrees below average. Heading into Monday night, another round of night/morning drizzle is expected along the coast and in the favored upslope regions.

Tuesday is now forecast to be the coolest day of the week with afternoon temperatures some 10 to 20 degrees below normal for this time of year. Temperatures remain below seasonal averages throughout much of next week with the potential for rain particularly across the North Bay late week as a weak frontal boundary sags southward across the region. This is as a cut-off low develops off of the northern California coast Tuesday with troughing persisting through the remainder of the week and potentially into next weekend. Still keeping an eye on the tropical eastern Pacific as it remains fairly active for any moisture that may be brought northward into California.

VFR prevails except for areas of stratus and fog/mist /MVFR-IFR/ along the immediate coast south of Point Reyes. A steady erosion of stratus on the northwestern edge continues to press southward likely due to drawn down mixing of drier air aloft over the coastal waters and land. At the same time a solid stratus intrusion is taking place over the Monterey Peninsula. This pattern will likely continue to evolve as such through sunset at which time nocturnal radiative cooling will commence allowing additional coastal stratus, fog/mist and drizzle to form including an inland intrusion tonight and Monday morning. Conditions improve to MVFR-VFR along the coastline Monday late morning and afternoon.
Vicinity of SFO, VFR except stratus /MVFR/ ceiling 10z-18z Monday then a stratus ceiling redevelops 04z Monday evening. West wind 15 to 25 knots until mid to late this evening, wind otherwise westerly 8 to 15 knots.
SFO Bridge Approach, Similar to SFO.
Monterey Bay Terminals, Stratus /MVFR-IFR/ developing through early evening, tonight and Monday morning. Tempo light drizzle KMRY 10z-14z, conditions improve to MVFR-VFR late Monday morning. West to northwest winds 5 to 15 knots except evening gusts to 20 knots in the Salinas Valley.
