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 pushed through first then the cold front will sweep into Western Oregon and the upper trough will slowly migrate to the east keeping the chance for wet weather with us for the week. That could spell another nice weekend ahead. We can hope.
