Some snow possible Thursday/Friday Dec. 24/25

A major storm system this week may take a similar track to the one that hit southeastern Minnesota and Wisconsin two weeks ago. This time, the exact track is more heavily dependent on the interaction of smaller scale weather disturbances, and that means there is a bit more uncertainty. There is also more warm air ahead of the storm, so areas such as Iowa that got all snow with the last storm may see a bit of sleet and freezing rain.

For northern Minnesota, accumulations will be heaviest to the southeast and lightest to the northwest. My initial guess is that Duluth will see 3-6", 1-3" will fall in Grand Rapids, 2-5" in Brainerd, and up to an inch will fall in Bemidji. There will be quite a bit of wind with this system as well, so that may make things feel a bit stormier than the snowfall amounts indicate.

After the storm passes, expect a day or two of colder weather, then dry weather and seasonable to mild temperatures for the rest of the holiday period.
