Snow cover discussion: The November 2021 snow cover analysis by the Rutgers Snow Laboratory is complete. The data indicate the North America snow cover is lagging behind normal ranking 11th least snowy in the 56-year climatology (Fig. 1). Meanwhile Eurasia is just-the-opposite ranking 9th snowiest since 1966 (Fig. 2). The northern hemisphere averages snowier than normal ranking 18th most snowy (Fig. 3). The polar sea ice cap extent of ice ranks 10th lowest in the satellite era (since 1979). Remarkably, there is no ice in Hudson Bay and waters north of Europe are wide open (Fig. 4). However, sea ice is above normal in the Bering Sea.
