Weather Synopsis for Friday & Friday
Look for scattered showers around the mountains today particularly on and west of the Cascade crest. Accumulations should remain very light with no more than an inch or two here and there. These showers should draw to a close in the afternoon as a high-pressure ridge builds and helps dry out the area. The biggest weather impact today should be the wind. Some locations will see moderate winds even at lower elevations. As the high-pressure builds in the afternoon, winds will decrease and turn more northerly.
Friday night and Saturday should be dry as the high-pressure shifts east across the state. You could find some low clouds and even patchy fog in the Passes and mountain valleys overnight and in the early morning hours. On Saturday our next weather system will approach the coast spreading clouds across the region. Warm air will push into the northwest ahead of the precipitation, increasing temperatures particularly in the western and southern parts of the forecast area. It looks like the high-pressure ridge will hold any precipitation at bay until Saturday night when we see our next chance for mountain snow.
