The National Weather Service forecast a "significant combination of hazardous winter weather" for several states.

In a one-two punch, more than 20 states in the Plains, Midwest, mid-Atlantic, and Northeast will be impacted by two back-to-back winter storms, with a third one not far behind, according to AccuWeather.

A second winter storm in as many days is slamming parts of the Midwest before rolling toward the East Coast. Major travel disruptions are likely.

The second winter storm of this week is bringing a widespread area of snowfall as well as some ice. Here's what to expect.
