________________

An Upper Level Low Pressure Trough (Shaded “U” shape with blue arrows) is controlling our weather for the near future. The graphic for days 1-3 shows the complex frontal systems set up for the Pacific Northwest bringing more rain. One moved in and the next one is shown on the way. Upper level HighPressure and surface low pressure combine to bring sunshine and dry us out. The graphic for days 3-7 shows that high pressure takeing over for the weekend into next week keeping us dry for a while.  For mountain snow conditions at the local ski areas check out their websites or give them a call.
