The high pressure ridge that gave us such a great weekend is moving eastward as a trough of low pressure (shaded area that’s “U” shaped offshore) will start pumping moist air and sending a frontal system our way. The warm front will push to our North, but the cold front will sweep into Western Oregon and the trough will slowly migrate to the east keeping the chace for wet weather with us for the week.
