The first of two frontal systems passed through this morning with the next front just about to hit the coast. The second front is weakening and directing most of its energy south of Stevens; therefore, the southern Cascades and the eastern slopes will get the majority of the snow today.
Long-term: High pressure builds off the western coast on Thursday. This is likely to block or split any storms trying to make it to the Pacific Northwest Mountains. The week is expected to end on the dry and possibly sunny side of things.
