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.
