Eskimos: Hey, where’s our snow??

North American Turned Upside down for temps:

Eskimo snow went south for the winter

The official explanation from NASA:

Snow fell in the U.S. Deep South, severe storms battered the East Coast, and International Falls, Minnesota, set a new temperature record: -46 degrees Fahrenheit (-43 degrees Celsius) on January 21. But in areas north of the United States and southern Canada, temperatures were above normal. In fact, unusual warmth forced residents of Iqaluit, capital of the Canadian territory of Nunavut, to cancel their New Year’s snowmobile parade.

This map of the United States, Canada, eastern Siberia, and Greenland shows temperature anomalies for January 9 to 16, 2011, compared to the same dates from 2003 through 2010. The anomalies are based on land surface temperatures observed by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite. Areas with above-average temperatures appear in red and orange, and areas with below-average temperatures appear in shades of blue. Oceans, lakes, and areas with insufficient data (usually because of persistent clouds) appear in gray.

EarthImage Explanation.

Arctic Ice maintained a pressure gradient that kept cold air dammed up over Canada for the most part.  With the melting of the Arctic Ice and open seas for longer periods, the normal fence holding back the jet stream has broken down, sending the northerly jet stream surging south to Atlanta, who now receive the Eskimo snows, when this air mass meets the Gulf’s warmer, moister flows.    Hence, the Iqaluit snow festival must move to Georgia, USA.
