429pm PDT Sunday September 25 2022
A well defined marine layer will support summerlike conditions with cooler and cloudier conditions near the coast through early in the week. Meanwhile, the interior is likely to warm into the 70s and 80s with mostly sunny afternoon conditions. Little day-to-day change expected through much of the week.
As of 01:50pm PDT Sunday...An increase in onshore flow and return of a well defined marine layer has resulted in a region-wide cooling trend. As of early this afternoon, stratus blankets the entire coastline while finally clearing across inland areas. As such, temperatures have been slow to warm with upper 50s to lower 60s holding at the coast while the interior is warming into the 70s and lower 80s. Look for additional warming by about 5-10 deg F across the interior through the afternoon while the coast may warm only an additional 5 degrees as the low clouds briefly scatter out.
The weather pattern will change very little heading into the start of the workweek with stratus making a quick return back inland this evening and overnight. Thus, look for only minor day-to-day changes in temperatures and overall conditions on Monday. A mid/upper level trough will then approach on Tuesday with increasing onshore winds and potential deepening of the marine layer. This may be enough to lead to patchy coastal drizzle by Tuesday morning, yet confidence remains low at this time on the development of widespread drizzle.
The mid/upper level feature will then shift inland through midweek while high pressure over the eastern Pacific builds towards the West Coast. This will result in slight warming for the latter half of the week, yet temperatures look to remain near seasonal averages. The overall pattern looks to remain progressive with another weak trough approaching the Pacific Northwest and northern California by next weekend. This should prevent/limit any heat concerns and more importantly dry offshore winds.
as of 04:28pm PDT Sunday...Locally breezy northwest winds for Sunday afternoon that will accelerate through the Golden Gate with stronger gusts in the San Francisco Bay. Stronger northwest gusts will steadily increase into mid-week, particularly along the immediate coastline south of Pigeon Point and down the Big Sur coast. A moderate period northwest swell continues through the week with a longer period southerly swell.
