An Upper Level Low Pressure Trough (Shaded “U” shape with blue arrows) is moving away to be followed by an Upper Level High Pressure Ridge (Shaded “Arch” shape with blue arrows). That means dry and warmer weather. The graphic for days 1-3 shows surface High Pressure building over the Pacific Northwest. The graphic for days 3-7 shows the next complex frontal systems that will be moving into Oregon Thursday through next Saturday. For mountain snow conditions at the local ski areas check out their websites or give them a call.
