This map shows forecasted temperature anomalies across North America for Saturday, Feb. 13. A large portion of central North America was under a dome of extremely cold arctic air that was displaced southward. The coldest temperatures, running from 12 to 18 C below average, were found across Western Canada and the northern U.S. Photo: tropicaltidbits.com
So look what happened to arctic temperatures as the cold arctic polar vortex shifted south. Well above normal temperatures in the arctic.
