WASHINGTON, Feb. 13 (UPI) -- A blast of Arctic air is set to make its way across the northeastern United States into Sunday, bringing a severe wind chill that may lead to below-freezing temperatures.
The National Weather Service said the weather pattern will be "the coldest air mass of the season". The polar vortex is set to induce a wind chill below -30 degrees by Saturday night in areas between the Great Lakes and New England.
