An Upper Level Low Pressure Trough (Shaded “U” shape with blue arrows) is taking over controlling our weather. The Eastern U.S. struggles through a major winter storm while we continue to get rain. The graphic for days 1-3 shows the next front that is moving into and through Oregon. The graphic for days 3-7 shows the next complex frontal system that will be moving through the Pacific Northwest Friday through Tuesday.  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.
