An Upper Level Low Pressure Trough (Shaded “U” shape with blue arrows) takes over replacing the weak high that gave us the sunshine Sunday. The graphic for days 1-3 shows the next cold front that is moving into Oregon. The graphic for days 3-7 shows the virtual parade of frontal systems that will be moving through the Pacific Northwest through next Monday. 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.
