Here we are with another blast of very cold air. As I have recently said this is that airmass that was over Alaska. The colder it is there the colder it will be here. Every situation is different. With Valley and around it to the state of North Carolina. Please be very careful, single digit temperatures can cause hypothermia or death.
When traveling make provision for blankets and other ways to keep warm. Drive at safe speeds and watch for black ice. Leave plenty of room for traffic and be kind.
Even Florida will suffer the cold with freeze warnings and crops down there that can be destroyed.
