A Midwest winter snow storm is forecast to bury northern states in as much as a foot of snow, in a a blizzard weather forecasters are saying may be the season's worst.

The heaviest snow is expected to blanket southeast North Dakota and northeast South Dakota, according to the Associated Press, which said the storm might be the worst of the winter.

The National Weather Service reported Tuesday that most of both Dakotas, Minnesota and Wisconsin are under a winter weather or blizzard warning that will last through Wednesday, and freezing rain is expected between southeast South Dakota and southern Minnesota and going east into southern Michigan.

A major winter storm with heavy snow and strong winds is expected to impact the North-Central U.S. on Tuesday. The same system will bring bring wintry weather to much of the Northeastern states by Wednesday afternoon, the NWS reported. Severe weather is expected over the central plains and lower Mississippi Valley for Tuesday. A strong upper trough moving into the West Coast will bring significant snowfall across local mountains.

Minneapolis, the largest city in the region, should be prepared for between three to six inches of wet snow, according to the AP.

The Brainerd [Minnesota] Dispatch has dubbed the impending Midwest winter snow storm, Snowmageddon, and quoted Duluth-based NWS meteorologist Amanda Graning on Monday:

This is going to happen. This is a big one. We are going to make up our winter here, Graning told the Dispatch. We have very high confidence in this storm. It's going to be nasty.

This year has seen one of the least-snowy seasons in the north Midwest in recent memory, so this relatively modest Midwest winter snow storm has a good chance of being the year's largest. Midwesterners who may have thought they would avoid any real snow this year had better get out the ice scrapers, snow shovels and boots.

In the Aberdeen (S.D.) area, snow totals in this storm could meet or exceed what we've had the whole winter, weather service meteorologist Mike Fowle told the AP Tuesday. March is one of our snowiest months in the Dakotas. People kind of got lulled into a sense of, 'We're not going to get much snow this winter,' and things could definitely change.

Many school districts in both Dakotas have already announced closures, and snowplows and salt spreaders are being prepped for the expected precipitation.

A winter storm watch is also in effect for parts of the Northeast United States, and eastern Massachusetts is bracing for more than three inches of snow and ice, according to The Boston Globe. The storm is expected to hit western and central Massachusetts the hardest.

Snow is currently expected to overspread southern New England Wednesday afternoon and transition to a wintry mix Wednesday evening,'' the NWS told the Globe on Tuesday. The heaviest precipitation should occur from late Wednesday into Thursday morning.''
