_______________

A trough of low pressure is sitting along the shore (see shaded areas and blue arrows) and will be moving eastward. A  storm system has already moved through Oregon  bringing the   chance of rain back. There will be a break without rain Tuesday and Wednesday due to a building high pressure ridge offshore moving in behind the trough and then another frontal system will bring the chance of rain back between late Wednesday and Thursday .
