Very little to talk about as the stretch of very pleasant if unexciting weather continues.
Today and Wednesday srn CA will be covered by a ridge with hgts around 584 dam. Offshore flow from both the north and east will continue through the period. Skies will be clear through the two day period save for a few low clouds across western SBA county each morning. The offshore push will be a little stronger this morning than on Monday and there will be some canyon winds. The winds will strongest across portions of the Central Coast where they could approach advisory levels. The stronger offshore flow will likely bring a few degrees of warming to the csts and vlys today. The offshore flow will also bring cooler air into the interior. Max temps will end up in the 80s or 10 to 12 degrees above normal. Wednesday will be quite similar to today just a little less offshore flow - so a little less winds and a degree or two of cooling.
A large trof will approach the west coast on Thursday and will push the ridge to the east and hgts will fall through the day reaching 568 dam by the afternoon. The offshore flow will also flip to onshore. Most areas will cool 2 to 4 degrees, but the Central Coast which will be closest to the approaching trof will see 4 to 6 degrees of cooling. Despite the cooling max temps will remain about 8 degrees above normal.

Still not much if any clarity on the xtnd fcst. At least three large systems will smash into the PACNW. The first is slated to pinch off an upper low that is fcst to move into Baja during the day Friday. There now seems like there might be a lull between systems Sat and Maybe Sun and then maybe a stronger system sometime Monday thru Wednesday. There has not been much run to run consistency with the mdls and even less agreement between individual mdls so confidence really remains quite low.
Some rain seems very likely sometime Friday and Saturday although amounts will probably be on the light side. There does seem to be some consensus that Sunday will be the day least likely to have rain although there still is some chc. The details on the system early next week are still quite fuzzy but now it looks like it will be the biggest and wettest.
Hopefully the forecast will begin to coalesce later today or tomorrow.
