The storm could bring at least 6-12 inches to areas in the Cascade Mountains in Washington and Oregon and the higher elevations of northern California, forecasters said. Eastern parts of Washington and Oregon could see 1-3 inches of snow.
Wind gusts could top 60 mph, forecasters said.
The storm will join another system from the Southwest over the Midwest, producing travel-disrupting weather for the weekend, AccuWeather.com said.
Snow was expected to spread across northeastern Iowa, Minnesota, northern and central Wisconsin and parts of Michigan's Upper Peninsula Saturday.
A powerful cold front was forecast to mix with humid air, causing severe weather to spread across the South this weekend, meteorologists said.
