National Snow and Ice - December 2004
NCEI added Alaska climate divisions to its nClimDiv dataset on Friday, March 6, 2015, coincident with the release of the February 2015 monthly monitoring report. For more information on this data, please visit the Alaska Climate Divisions FAQ.
As can be seen in the animated image to the left, several significant snow storms affected the continental U.S. during December while most of Canada was snow-covered for the entire month. Sea ice increased over Hudson Bay and water bodies in the Canadian interior, while the Great Lakes remained ice-free during December. A notable snow event was captured in the image to the left as snow fell in southern Texas over the Christmas holiday. Over a foot was recorded in Victoria, Texas, while Brownsville, at the southern tip of the state, received 1.5 inches. A snow storm that impacted the Ohio Valley on the 22nd and 23rd caused parts of Indiana and Kentucky to receive more than their average seasonal total in just one day.
