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, but a frontal system sneaks in to bring a chance of rain for Wednesday and Thursday. The graphic for days 3-7 shows the next complex frontal system that will be moving into Oregon Friday. For mountain snow conditions at the local ski areas check out their websites or give them a call.
