Weather Synopsis for Thursday night through Saturday
Our cool and wet weather patten continues as we wrap up the week and head into the weekend. The upper trough responsible for Thursday's rain pushes inland overnight. This will cause precipitation and winds to increase. Expect moderate to strong and gusty winds in most locations. Rain and snow will also make their way over the crest and bring a period of more focused precipitation to the eastern forecast zones.
Instead of clearing out, the trough stalls and expands. It won't be quite as wet Friday and Friday night, but we won't exactly dry out either. Showers and clouds will be most prevalent in the morning. With daytime heating and a little sunshine, we should see clouds gather, and skies begin to part. While you could find a sun break just about anywhere, they'll be more prevalent east of the crest. Friday night, onshore flow and lingering moisture should draw low-level clouds back into the west slopes and passes with a return to cloudy skies.
A more organized storm in the Gulf of Alaska will eject several waves of moisture toward the Pacific Northwest over the weekend and into the first part of next week. The first of these pulses arrives Saturday. Precipitation should start in the Olympics and North Cascades during the morning before spreading further south in the afternoon. Similar to most of these recent events, this storm doesn't look particularly wet, but you'll see an increase in precipitation and ridgeline winds as the front crosses the mountains.

Extended Weather Synopsis for Saturday night through Monday
After several days of mild and wet weather, temperatures will finally start to cool, and snow levels lower. A cold front originating from the Pacific low should push through the area Sunday night. This will bring yet another round of precipitation and stronger winds followed by post-frontal showers. It won't be particularly cold, but we could see snow, or at least a rain/snow mix, at Cascade Pass levels by Monday morning. This doesn't look like the end of our cool and unsettled weather pattern. Additional disturbances appear to swing through the region throughout the week. However, the exact timing and strength of each storm is a bit unclear.
