Temperatures ranging from 10 to 20 degrees below normal are expected to reach as far south as the southern United States, forecasters said.
In addition to the cold, snow is likely in several regions, including the Great Lakes, parts of the Northeast, and the Appalachian Mountains.
Residents in these areas should prepare for colder-than-usual conditions and potential snowfall in the coming days.
