Frigid temperatures are pouring into the Northeast after a powerful winter storm brought up to 2 feet of snow in some places over the weekend, creating dangerous travel conditions Monday with the risk of frostbite or hypothermia for anyone outdoors with exposed skin.

The National Weather Service's Weather Prediction Center said that frigid air from Canada has inundated the region in the wake of the storm.

"High temperatures today will be more than 20 degrees below normal across much of the Northeast," the NWS said. "The flow of frigid air over the Great Lakes will promote lake-effect snow as well as upslope snowfall over parts of the central Appalachians through this evening."
