Significant Snowfall Becoming More Likely Dec. 24-25

The model forecast tracks for the major storm system that will be moving through the central U.S. over Christmas have shifted to the northwest, and it is beginning to look like most of Minnesota may see moderate to heavy snowfall from this system. The most likely area for heavy snow is still southern Minnesota, where snow totals in the 10-20 inch range look likely. In northern Minnesota, amounts of 5-8" are now becoming a possibility.

The low pressure center will move from near Dallas, TX early Wednesday evening to just south of Des Moines, IA by Friday morning. Snow will begin Wednesday afternoon in southern Minnesota and will probably reach the far northeastern part of Minnesota by late Thrusday evening. The heaviest snow will occur during the early part of the storm, but since the storm will be moving slowly, light snow may persist into Saturday.

Temperatures will cool down behind the storm, but they do not look extremely cold, and we may see warmer than average temperatures by the beginning of January.
