An Upper Level High Pressure Ridge (Shaded “Arch” shape with blue arrows) that took over control of the Pacific Northwest weather bringing lots of sunshine and heat is slowly moving away to be replaced by a trough of low pressure (Shaded “U” shape with blue arrows). The graphics for days 1-3 shows a frontal system moving through Oregon cooling us down dramatically bringing in cooler and moist marine air. The graphics for days 3-7 show no major frontal systems over the Pacific Northwest through next Sunday.
