A new round of snow from an incoming storm system for the Northwest will lead to a swath of snow from the mountains of the Pacific Northwest through portions of the northern Rockies, Northern Plains, Midwest, and interior Northeast from now through Saturday.

On Thursday, snow will impact western Washington, including the Cascades, as well as northern parts of Oregon and Idaho and much of Montana. Meanwhile at the coast from Seattle southward to Medford, it will be rain due to above-freezing air in the lower elevations.

That snow will persist into our Friday for the same areas as well as in northwestern Wyoming, portions of the Dakotas, most of Iowa, and northern Illinois and Indiana. This storm is a clipper-like system, meaning that it is moisture-starved and fast moving. Because of these characteristic, snowfall totals will be light for the Northern Plains and Midwest regions. Now in the Northwest at the highest mountain peaks, it will be a different story. Some peaks will likely exceed snowfall totals in excess of three feet through Saturday.

Speaking of Saturday, the snow will wind down across much of Washington and Oregon while it continues across portions of the interior Northwest. Lingering light snow showers can also be expected for parts of the Northeast Plains from a new storm system while the interior Northeast deals with light showers from the current system.

By Sunday, this storm system will depart the region and it’s energy will actually phase with a developing coastal storm, which may bring minor snowfall totals to the Northeast coast.

Again, snowfall totals will be light for most locations. Our snowfall map below reflects the expected snowfall totals from solely this storm system.
