Slow-moving storm set to slam Northwest with heavy snow, rain

The Northwest has been hit with a series of storms recently.

Up to another foot of snow fell in parts of the Cascade Mountains in the Pacific Northwest over the last 48 hours and more is on the way.

The storm system is slowly moving east Friday morning, with rain and snow already spreading into Washington state.

The actual storm -- with gusty winds, snow and rain -- will move into the Northwest on Saturday morning and will last through the afternoon.

The storm will continue to move inland, bringing heavy snow to the Rockies on Sunday from Montana to Utah and Colorado. The total weekend snowfall is expected to be measured in feet, and some areas from the Cascades into the Rockies could see several feet of snow by Sunday night.

Rain will fall in coastal areas of Washington and Oregon, with some areas seeing up to 3 inches.

Arctic intrusion

But all of this warm weather will end next week, starting in Midwest early in the week and then the Northeast by the end of the week. Several waves of arctic air will move into the lower 48 states from the Dakotas into the Carolinas.

The cold blast reaches the Midwest and the Great Lakes on Monday and Tuesday, and then moves into the Northeast on Wednesday afternoon into Thursday and Friday.

A second shot of arctic air will move into the Midwest and the Great Lakes the following weekend.
