Monday and Monday night (February 15)
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.
