An Upper Level Low Pressure Trough (Shaded “U” shape with blue arrows) is still controlling our weather. The Eastern U.S. struggles through a major winter storm while we just get rain. The graphic for days 1-3 shows the front that is moving through and away from Oregon. Drying being the front for Thursday. The graphic for days 3-7 shows the next complex frontal system that will be moving through the Pacific Northwest Saturday and the break from storms that follow.  For mountain snow conditions at the local ski areas check out their websites or give them a call. Hope you changed your clocks last night.
