A seasonal weather pattern will continue through midweek with a well established marine layer along the coast. Temperatures will continue to run near or a few degrees below normal at least through Thursday with coastal highs in the 60s warming to the 80s inland while nights remain cool with onshore breezes. An inland warming trend is forecast Friday through the weekend as high pressure builds and 90s become more common for the interior valleys while the marine layer will keep the coast in the 60s.

A 2000 foot marine layer and steady onshore breezes have kept a well established marine layer in place along the coast today. The City has seen little or no sunshine with low clouds still covering the Berkeley hills. Downtown SF recorded its first measurable 0.01 precip of the month this morning as drizzle associated with the marine layer was enough to tip the bucket. No real hot temps to speak of today with mainly 70s around the bays and 80s inland. Even the usual hot spots of interior Monterey county haven't reached 90 degrees yet today.
Given the 2000 foot marine layer and 3.3 mb SFO-Sac gradient expect an early push of stratus tonight with most areas below 2000 feet covered in low clouds by morning.

The 500 mb pattern trends more zonal by around Thursday with 850 mb temps forecast to warm heading into the weekend. Onshore wind pattern will remain in place with a likely well established coastal marine layer. Inland highs back into the lower to mid 90s should become more common for places like Livermore which would be only a few degrees above normal. So a pretty typical late June pattern remains forecast with temps ranging from 60 in SF to the 90s for the interior valleys but not expecting any triple digit heat.
Beyond the weekend as we head towards the first week of July and the 4th of July holiday the outlook suggests no abnormally hot weather with monsoon moisture currently progged to stay over the deserts of southern CA. Best forecast at this time calls for continued seasonably warm days with cool/mild nights that would allow the summertime coastal marine layer to remain well established with SSTs values running in the lower 50s along the coast.
