Yes, but it has been unusually cold, even by US standards. I quote:
"According to data from the Southeast Regional Climate Center, the following cities recorded coldest ever Dec. 23-Jan. 5 stretch: Bangor, Maine, Worcester, Massachusetts, Buffalo, New York, Flint, Michigan, Green Bay, Wisconsin, Duluth, Minnesota, Rockford, Illinois, Waterloo, Iowa, Lincoln, Nebraska.
According to the SERCC, dozens of other cities from the northern Rockies to Texas to the Great Lakes and East Coast had at least a top-five ever coldest two-week stretch ending Jan. 5."
