The calendar says spring but the thermometers will likely be showing winter temperatures to a majority of the U.S. as another arctic blast sweeps in to start the week.

Forecasters say that temperatures could be as much as 20 degrees below normal in parts of the Midwest and Northwest and 25 degrees below normal in the upper Midwest.

Northern Minnesota cities such as Duluth and International Falls could see high temperatures this week that will stay in the teens and lows well below zero.  Cities as far south as St. Louis and Cincinnati could see highs only around 30.

In addition, upper New England faces the strong possibility of a blizzard striking around mid-week.  Parts of Rhode Island, Massachusetts and Maine could see upwards of a foot of snow before the weekend.

Other parts of New England could see several inches of snow as the bulk of the blizzard will just miss their areas.

A warming trend is expected to start over the weekend.
