A trough of low pressure is setting up offshore and will be moving toward us (See “U” shape ) and that means the cooler weather will remain with us for a while longer.  Weak high pressure will warm us up a little early next week then a low pressure trough and a cold front will be moving through Oregon next Wednesday to bring temperatures back down again.
