A couple areas of low pressure, one passing by to our north/northeast with another one diving southeast out of the Northern Plains combined with a cold front which moves through the Northland Monday night will keep the weather a little bit unsettled as scattered snow showers and flurries linger across the area along with partly to mostly cloudy skies.  Highs tomorrow will be in the 20s and 30s with lows in the teens and 20s.  South or southwest winds through Monday evening at 10 to 20 mph with south or northwest winds late Monday night.
