first snowfall in everett/seattle area expected on thursday AND friday. We will see if there right, ya can't trust those weather guys that often but i'm excited!!! here's the scoop.. ... Coldest air mass of the season expected to invade western Washington the latter part of this week... The coldest air of the season thus far is anticipated to arrive later this week as a modified Arctic front sweeps south across western Washington. Daytime temperatures are only expected to be in the low to mid 30s across The Lowlands this weekend and in the teens in the Cascade passes. There is also the potential for significant snowfall to occur over parts of The Lowlands Thursday night into Friday morning as a storm system moves across the area. At this time... the track and timing of this feature were still uncertain. However if the latest numerical weather models do verify... snowfall amounts of an inch or more will end up falling across parts of The Lowlands.
