PORTLAND, Maine — A teeth-chattering cold wave with subzero temperatures is expected to keep its icy grip on much of the eastern United States into the weekend before seasonable temperatures bring relief.
A polar air mass blamed for multiple deaths in the Midwest moved into the Northeast on Wednesday, prompting the National Weather Service to issue wind chill warnings across upstate New York and northern New England.
The Canadian air mass that arrived in the Upper Midwest over the weekend plunged temperatures to record lows in some areas, forced schools to close, delayed commuter trains and subways and kept plumbers busy with frozen pipes. A ski resort in New Hampshire shut down Wednesday because of unsafe ski conditions: a predicted wind chill of 48 degrees below zero.
The coldest temperatures were expected Wednesday and today, after which conditions should slowly moderate before returning to normal, according to the National Weather Service.
