And the second system is forecast to move ashore into California on Monday (yellow outlined area on map) Will need to keep an eye on the track of this one as computer models have it lifting far enough north where it could impact northeast Minnesota and northwest Wisconsin bringing some more snow (possibly a significant amount) to parts of the area around the middle of next week, or from ~December 29 to December 31.

The system on Sunday could bring a widespread 1 to 2 inch snowfall to most of northeast Minnesota and northwest Wisconsin the way it looks now, but some changes are certainly possible over the next day or two.
