Today’s Image of the Day from NASA Earth Observatory is a map that shows irregular land surface temperatures throughout the month of November 2018.

“This tends to push storm tracks farther south, which allows for the dominant flow over land to be from the north, which draws cold air from the poles,” explained meteorologist Joseph Munchak who is based at NASA’s Goddard Space Flight Center.

The map represents land surface temperature anomalies in North America for the month of November based on data from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite,
