The official start of spring sits exactly one week away, but Old Man Winter isn’t going away quietly. Across much of the Northern United States a strong winter storm is expected to bring several feet of snow to a number of states.

A potential bomb cyclone is hovering over the Great Lakes region as Wisconsin and Michigan prepare for up to three feet of snow. However, two states that sit due West are expected to get the brunt of a strong winter storm.

The National Weather Service issued a series of new winter storm warnings as a new atmospheric river brings heavy snowfall to the Northern Rocky Mountains.

“Meanwhile, an active Atmospheric River pattern across the Pacific Northwest into the northern Rockies will continue to bring heavy lower elevation/coastal rain and high elevation snow for the next couple of days. Additional snowfall totals in the Olympics/Cascades and northern Rockies will be as much as two to four feet through the weekend,” the NWS said.

Idaho: While the NWS capped its national forecast at four feet, the local Missoula office of the National Weather Service is calling for up to five feet of snow in Dixie, ID. “Total snow accumulations between three and eight inches in the lower elevations and two to five feet of snow above 5,000 feet,” it said as 40 mph winds combine for “difficult or impossible” travel conditions.

Those in the region are told to expect considerable disruptions to normal activities and dangerous or impossible traveling conditions. Residents are warned to delay all travel in the impacted areas if possible and told to expect widespread closures and disruptions to infrastructure.
