As 2017 drew toward a close and 2018 began, Arctic air continued to spill into the eastern United States and Canada blasting off bitterly cold air through the New Year’s Eve, the coldest in recent memory for many areas. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image of the frozen Midwest and Northeast landscape on January 2, 2018. See the MODIS temperature anomaly map.
