White Christmas Tracker: In the bag for Upper Midwest
Today's storm has just about guaranteed a White Christmas for most of the Upper Midwest. In fact, this year could be pretty close to "climatology" as far as the southern extent of snowfall. A coating of white is likely to remain south of an Omaha-Des Moines-Chicago line by Christmas Day.
Here's a look at the climatological probability for a White Christmas from NOAA.
Safe travels!
