In the upper atmosphere the jet stream has a series of ridges and troughs in it just upstream, those features will drive and up and down weather pattern into the end of the week.
Currently a ridge is building in and this morning it produced offshore winds and mild temps.
A cold front will produce increasing clouds with a few areas of drizzle Wednesday night/Thursday morning, followed by stronger northwesterly winds on Thursday afternoon 15-30mph.
Strong northwesterly winds will continue into Friday 15-30 with gusts to 40mph), winds should decrease a little on Saturday and Sunday but still be quite strong at 15-25mph
These onshore winds will keep the temperatures mild and the skies mostly clear.
I still see a strong high-pressure ridge will developing over California next week. This high-pressure system will produce offshore winds and warm temps through much of California. Fire risk will be a concern as there are still no strong signs of significant rainfall.
