A upper level low pressure trough (“U” shape on the yellow line) is moving eastward away from the Pacific Northwest. A high pressure ridge (“Arch” shape on the yellow line ) over Western Canada) gave us just a slight chance of sprinkles Saturday. The serious chance of rain should hold off until about Tuesday, but we’re looking at a slight chance of getting wet until then.late tonight. A frontal system will be moving through Oregon overnight tonight and early Monday. Another trough of low pressure will will head our way pushing yet another frontal system (position shown is Wednesday) that will approach the coast by early Tuesday.
