The Southeast gets a mix of everything

However, it is the system’s slow forward speed that provides the system for a freezing snowstorm that can strike millions of people.

Said Friday morning. “At this time, icing is not expected to reach our far western zones, where a foot or more of heavy snow is possible.”

Inland cities such as Charleston, Pittsburgh, Buffalo, Syracuse and Burlington, Vermont will experience heavy snowfall.
