Weather Update: Saturday, December 13 —
A surface arctic front made it’s way through West Tennessee late this afternoon. A large and very potent area of High pressure (1040mb) will slide from the northern High Plains east along I-70 towards Central Illinois and Indiana trailing the Alberta Clipper.

This will force a dense arctic air mass south across the Midsouth tonight and most of Sunday. Tonight though most of the day Sunday. There will be a pressure gradient which will resolve by creating a persistent wind from the north. Combination of the arctic air and wind will create a dangerous wind chill near 0°F, or slightly below zero at times, especially near Kentucky/Tennessee border. If you can avoid being outdoors overnight and early Sunday, that would be best. However, for some that is not an option. if you have to be out, frostbite can occur in less than 30 minutes with antecedent conditions Sunday morning. Employ the ‘Four Ps’: People, Pipes, Pets and your plants. Protect them from the harsh conditions.

Tonight And Sunday Morning:
National Weather Service in Memphis has issued a Cold Weather Advisory due to the extreme cold and wind chills generally less than 5°F from midnight until 9:00 AM. I will have a full update and video forecast update coming up on 7 Eyewitness News at 10:00 PM ABC And CBS
