Weather Synopsis for Sunday & Saturday
Cool upper level troughing is over the area with some leftover scattered snow showers mainly for the Olympics and northwest Cascades to about Stevens Pass this morning. Scattered clouds, a mix of low and high clouds remain over most areas this morning. Despite the early cloud cover, we expect the giant yellow orb to make an appearance today for all areas. Freezing levels should remain on the cool side and winds will remain light.
Northerly surface gradients on Sunday will become offshore easterly gradients on Monday as high pressure builds east of the Cascades. A moderate easterly breeze should be seen in the Cascade Passes and down around Mt. Hood later tonight through Monday. A weak system off the California coast will rotate up bands of light precipitation on Monday. The low levels will be quite dry such that the main affect for the Washington Cascades will be increasing high clouds from the south through the day with slightly lowering ceilings while light precipitation develops for Mt. Hood in the afternoon. Light bands of rain and snow should develop for all areas Monday night.
