Western Washington is our destination for today’s forecast. Not Puget Sound though, but rather an entirely different climate on the east side of the Cascades.

At 1155AM, PT, Wenatchee was reporting fair skies with a temperature of 49 degrees. The jet was nearly directly overhead, and was bringing some striated high clouds to the Pacific Northwest in general, but specifically some fog and light precipitation at the higher terrain of the Cascades. This will dissipate, and aside from the continued high clouds, Wenatchee will remain in the clear through Thursday.
The next feature out of the Gulf of Alaska will arrive early on Friday and bring a swift bout of showers to the region, some of which will likely snake its way to Wenatchee, even as most gets wasted in the Cascades. Expect a gloomy end to the week, thanks to the persistent clouds on Friday.

It looks like a pretty grim day on the eastern slope of the Cascades on Friday. Here is the satellite with clouds streaming across the PAcific Northwest associated with the jet.
