Another storm system to bring rain, mountain snow from the Northwest to Rockies

A foot or more of new snow could fall in parts of the Rockies by Tuesday night

A storm system pushing into the West Coast from the Pacific Ocean will bring rain and mountain snow from the Pacific Northwest into the Rockies early this week.

Currently, light rain is falling from northern Washington southward through Oregon and Northern California, but as the system advances to the east, precipitation will become steadier and heavier.

By Monday afternoon, heavier rain will be falling in central and eastern Washington, as well as coastal areas of Oregon. And while the rain will be falling from Portland to Eugene and Medford, as you get into the higher elevations of the Cascades, the rain will change to snow.

The same holds true in eastern Oregon, where snow will be falling in the higher elevations but will be all rain in places like La Grande and Burns, Oregon.

High rain totals aren't expected in the region, but some areas of the Cascades and Rockies could pick up a foot or more of new snow through Tuesday night.

The highest snow totals will be seen across the Cascades in Oregon, where up to a foot could fall. Lighter accumulations are expected in the mountains in Washington.

However, it's a different story in the Rockies, where the highest peaks in central Idaho could see a foot or more of fresh powder.
