Much Colder Air to Return to the Midwest, East Next Week Thanks to a Major Pattern Change

A major pattern change could occur next week, which could bring much colder air to the Midwest and parts of the Northeast. Milder air is in place over the Northeastern part of the country right now but could be pushed out quickly next week with the incoming pattern change. There is also the possibility of a more stormy pattern to unfold over the country when this change occurs and so then we could be talking about some snow coming into the forecast.
