Issued at 1237 AM PDT Sun May 26 2024 Warmer today as a warming trend kicks off through the week. Afternoon highs slightly above normal on tap for next weekend. && .UPDATE...
-- Changed Discussion --
Issued at 854 AM PDT Sun May 26 2024 Much less marine layer influence to start the day. Visible satellite imagery still shows some coastal stratus nudging its way locally inland, but coverage is much less than 24 hours ago. It goes with out saying, much less in the way of drizzle this morning too. Only one or two reports of drizzle. Morning clouds are expected to clear back to the coast with some patchy stratus hugging the coast through the afternoon. All in all, a pleasant Sunday with warmer temperatures than Saturday. MM

&& .SHORT TERM... (Today and tonight) Issued at 1237 AM PDT Sun May 26 2024 Continued quiet weather to round out the weekend. Warmer today compared to yesterday as the upper low responsible for the drizzle the last couple of days finally moves out and a broad ridge builds in its wake. Temperatures warm to around seasonal normals with highs inland in the mid-to-upper 70s and lower 60s closer to the coast. Though dry weather persists, as does onshore flow, providing decent moisture return through the week. && .LONG TERM... (Monday through Saturday) Issued at 1237 AM PDT Sun May 26 2024 Seasonal temps last through the week with no real large-scale change in the pattern. A progressive, deep upper low traverses through the Pacific NW midweek to flatten the ridge a bit. This will keep any further warming at bay through the middle of the week, but isn`t expected to bring any other notable change to the sensible weather. As this feature departs, the ridge builds back and a secondary warming trend continues into the weekend. Not staring down any major heat wave by any means, but there`s a good chance our afternoon highs are slightly above normal by next weekend. && .AVIATION... (12Z TAFS) Issued at 400 AM PDT Sun May 26 2024 MVFR low clouds are affecting most of the coastal terminals early this morning and will persist through the late morning to early afternoon hours before clearing back towards the coast. Thereafter look for breezy onshore winds, although not as strong overall compared to the past few days. Low clouds return early this evening for the Monterey Bay terminals and later tonight around the Bay Area. Vicinity of SFO...MVFR low clouds persisting until around 21Z today before scattering out. Breezy onshore winds this afternoon with gusts to around 25kt. MVFR clouds return tonight around/after 08Z with winds easing to around 10 kt. SFO Bridge Approach...Similar to SFO. Monterey Bay Terminals...MVFR low clouds persisting until around 20Z before scattering out. Clouds may linger a bit longer in the vicinity of KMRY. Expect onshore breezes generally around 10 kt or less this afternoon, except 15-20 kt gusts through the Salinas Valley after 20Z. Winds easing early this evening with MVFR to high end IFR stratus returning around/after 03Z. && .MARINE...
