Sunday night snow?

Most forecast models suggest a system could be cold enough for snow somewhere in southern Minnesota Sunday night.

Today’s forecast model trends have shoved the bulk of the snow south of the Twin Cities. The Canadian model is typical, suggesting a dusting in the Twin Cities with potential accumulating snow in southeast Minnesota and northwest Wisconsin late Sunday into Monday.
