Despite the fact spring is showing up early this year, we must remember winter isn’t over yet.

A major winter storm is set to impact millions this week, from coast to coast, with heavy snow, dangerous winds, possible blizzard conditions and for some, the coldest temperatures of the season.

The storm is already showing signs of life along the West Coast, as snow and rain is already falling across the Pacific Northwest, adding to their already blockbuster snow season.

“Storm total snowfall will likely be measured in feet for many of the mountain ranges across the West,” the Weather Prediction Center said.

The heavy snow and extreme cold will move into the Rockies and Midwest as well, where the storm could have its biggest effects.

Blizzard warnings are in place for southern Wyoming, where nearly two feet of snow and winds gusting more than 70 mph will create blinding conditions. The weather service also warns of wind chills falling to 25 degrees below zero.

The storm releases its fury on the Midwest Tuesday through Thursday, with two rounds of snow. The first round on Tuesday will bring four to six inches of snow to much of the region.

Thursday will also bring a swath of icy weather for some big cities, including Chicago. Ice could also be a problem for parts of the Ohio Valley, yet pinpointing exactly where it will occur is challenging this far out.
