An Upper Level Low Pressure Trough (Shaded “U” shape with blue arrows) is controlling our weather for the foreseeable future. The graphic for days 1-3 shows the complex frontal system set up for the Pacific Northwest bringing rain and possibly a little snow. The graphic for days 3-7 shows more active frontal systems heading our way late this week into next week. For mountain snow conditions at the local ski areas check out their websites or give them a call.
