The first wave of energy and moisture will approach the coast this evening, with snow increasing into Friday. The Pacific Northwest will see the moisture first as a low pressure center and cold front moves into the region.
A second cold front will start to dive further to the south on Saturday, pushing moisture into the mountains of California. Snow will likely continue into early next week as the upper level wind flow will favor humidity pushing in from the Pacific Ocean.
