Thanks to a couple winter storms that brought considerable snowfall to much of the Upper Mississippi River Valley, a "white" Christmas is assured. By definition, a "white Christmas" is one in which there is either an inch of snow on the ground on Christmas morning, or snow falls on that day. While this one is assured, this isn't always the case. The last non-white Christmas occurred back in 2006. That December was very mild with hardly any snow falling.

2009 had ample snow on the ground Christmas morning, but a winter storm brought quite a variety of winter precipitation to the region for the 23rd through 25th. In fact, many locations across the region actually had rainfall Christmas morning rather than snow. Learn more about this storm, what fell and why, via our storm summary for this winter event.
