The high pressure ridge that gave us the sunshine has moved eastward to be replaced by a trough of low pressure and that will be replaced by another high pressure ridge.  The result will be sunshine that won’t last very long, but first another frontal system, still over the Pacific, will be bringing back the rain for Friday, though most of it will move into Southern California.  Yet another storm system will move in Sunday bringing with it more rainy days that will continue next week.
