(Today and tonight) Issued at 1259 AM PDT Sat May 25 2024 Deep, moist marine layer this morning allowing for stratus to push well inland. Additionally, a weak passing trough has provided just enough lift to bring drizzle to areas along the coast and in the hills. Several locations along the SF Peninsula, East Bay hills, and Central Coast have actually measured a few hundredths of an inch here and there as a result. Skies will gradually clear inland today with some coastal locations remaining in the clouds. Another cool day with afternoon highs similar to yesterday.

&& .AVIATION... (00Z TAFS) Issued at 550 PM PDT Fri May 24 2024 Most of the region has cleared out, but MVFR stratus continues over the SF Bay terminals and the area around MRY. Not expecting any clearing for those terminals for the rest of the day; if they do clear out, it will be short-lived and transitory. Breezy northwesterly winds will continue into the evening, diminishing at night before resuming Saturday afternoon. High confidence in further stratus development across the region this evening, except at the North Bay terminals where confidence is moderate. Along the coast, and in the SF Bay and Monterey Bay regions, ceilings are expected to decrease to IFR-LIFR. Stratus mixes out late Saturday morning with breezy northwest flow resuming in the afternoon. Vicinity of SFO... MVFR stratus continues through the day. Strong west winds gusting to 30 gusts will continue through the evening. At this time, low confidence that winds will gust above 35 knots. Will monitor evolution of winds throughout the day and will amend TAF if necessary. High confidence of MVFR or marginal IFR stratus at the terminal area tonight, clearing late Saturday morning with strong west winds Saturday afternoon. SFO Bridge Approach... Similar to SFO. Monterey Bay Terminals... MRY should expect MVFR ceilings through the day, with some greater uncertainty at SNS although continuing ceilings are also favored there. Breezy and gusty northwest winds continue through the evening. Overnight, ceilings drop to the IFR- LIFR level across the region. Clearing time is expected late Saturday morning at SNS, and a moderate confidence that MRY clears out at a similar time as well, although some model output keeps ceilings through Saturday. && .MARINE... (Tonight through next Thursday) Issued at 926 PM PDT Fri May 24 2024 Mainly gusty northwest winds will continue over the coastal waters over Memorial Day weekend and to the middle of next week. Afternoon and evening onshore winds will also become breezy to gusty over the bays during the forecast period. && .MTR WATCHES/WARNINGS/ADVISORIES...
