Winter Storm Nacio will bring snow from the upper Ohio Valley and mid-South into the mid-Atlantic into early Wednesday. Nacio was named Monday afternoon when winter storm warnings were issued by the National Weather Service for more than two million people in parts of Maryland, southeastern Pennsylvania, southern New Jersey and northern Delaware, as well as along the border between Tennessee and North Carolina and part of eastern West Virginia, meeting The Weather Channel's population requirement for a named winter storm.

The snow from Nacio is partially due to upper-level energy accompanying a southward dip in jet stream that is ushering in arctic air across the eastern states. Also playing a role is an area of low pressure developing off the East Coast, and a separate low pressure system in the Great Lakes. This snow is following quickly on the heels of Winter Storm Mars, which will continue to impact New England through early Tuesday.
