Cold weather will stick around through the weekend from the Upper Midwest to the mid-Atlantic and New England.

 

The bitterly cold air will slosh out by the end of the week and will not dip into the Deep South. Moderate cold (lower-than-average temperatures) will remain in place into Sunday in most areas farther north.

According to Expert Senior Meteorologist Henry Margusity, "The coldest air mass in North America was sitting just north of the Great Lakes over central and northern Ontario and western and central Quebec Tuesday morning."
