The graphics for days 1-3 show the warm front that moves through Oregon today. Weak high pressure will help dry us for a short time today, but the cold front that follows behind pushes in tonight. An Upper Level Low Pressure Trough will persist through the weekend to keep the precipitation chance with us. The graphics for days 3-7 show the next frontal systems that will move through the Pacific Northwest Saturday.
