December 26, 2011Snow Cover vs 2010
























December 26, 2011 Snow Cover Compared to December 26, 2010
What a huge difference in snow cover across the U.S. this December (2011) compared to last year. December 26, 2011 finds much of the Great Plains up into Canada as well as the Great Lakes and NE U.S. without a snow cover compared to last year (December 26, 2010) when the southern edge of the snow cover extended from the Arkansas/Missouri border across to Georgia. Last year the entire Great Lakes region and down the east coast was snow covered. The only area with snow cover this year that didn't have snow cover last year is the SW U.S. region.

December 26, 2011 Conterminous U.S. snowcover = 27.5%
December 26, 2010 Conterminous U.S. snowcover = 52.9%
