Title: Odds of a White Christmas

After a stretch of mild temperatures over many areas of the United States over the past week, snow cover has melted away in some areas. Will cold and snow return to bring a White Christmas to your area?

Below are two charts that show the current snow and ice cover across North America as well as the whole Northern Hemisphere. Snow cover is extensive across Canada and into portions of New England, Great Lakes, Northern Plains and the Rockies. Despite the warm up, snow remains from the big Mid Atlantic snow storm a couple of weeks ago.


Across the Northern Hemisphere the snow cover is most extensive across northeast Europe, Siberia and portions of Asia. The extensive snow cover in those areas will bolster the chances for some colder air intrusions over the North Pole and into North America in January and February.


While temperatures across the lower 48 states will be a little warmer than average this week, a change to colder temperatures and better chances for snow will increase the chances for a white Christmas over many areas of the Northern Plains and High Plains this weekend and into Christmas week.
