Upper Level High Pressure (Shaded “Arch” shape with blue arrows) moved in to dry us out for the weekend, but that will change by tonight. The graphics for days 1-3 show the next frontal system approaching the Pacific Northwest. An Upper Level Low Pressure Trough will take over this week to help return the rain. The graphics for days 3-7 show the next series frontal systems heading our way Thursday through next Monday.
