Weather Synopsis for Friday & Saturday
A low pressure system stalled off the coast continues to rotate showers into the area this morning. Most of the precipitation is focused in the Olympics and western foothills of the Cascades. The low will finally drift southward today and drag most of the moisture with it. While many places may start the day with lots of clouds, the general trend will be for drying and clearing. An unstable atmosphere overhead allows daytime warming to help reinvigorate showers in the afternoon and create some popcorn cumulus clouds. Precipitation should be most prevalent north of I-90 in the eastern forecast zones. As flow shifts more northerly, showers will approach from the N or NE.
While a few flurries and sprinkles could linger into the early evening, the majority of locations stay dry overnight. Mostly clear skies will allow temperature inversions to develop in the mountain valleys and passes, along with patchy valley fog. A high pressure ridge approaches the region on Saturday. Expect plenty of sunshine, light winds, and warm (but not hot) temperatures. The dry and warm pattern should stay with us at least through early next week.

Directions above indicate the direction the wind blows from on the 16-point cardinal scale. These winds indicate "free" winds, or those winds in the atmosphere not influenced by terrain. Topographical effects may produce greater or lower wind speeds in certain locations as well as significant variations in direction.
