An Upper Level Low Pressure Trough (Shaded “U” shape with blue arrows) has taken control of our weather sending a lot of moisture into the Pacific Northwest. The graphic for days 1-3 shows the frontal system moving through Oregon. The graphic for days 3-7 shows a series of frontal systems that will keep our weather active through next Wednesday. For mountain snow conditions at the local ski areas check out their websites or give them a call.
