A trough of low pressure (shaded area that’s “U” shaped over Oregon) is pumping cool moist air in behind the frontal system that passed through on Monday. The upper trough will slowly migrate to the east keeping the chance for wet weather and cooler temperatures with us for a while. High pressure will build in at the end the week. So far, it looks like another nice weekend ahead. We can hope. The next storm system will be approaching the coast Monday.
