The Tennessee Valley could see some of the heaviest snowfall, with 6 inches expected on Friday. A wide swath of the country is under winter weather warnings and advisories and will see impacts including "widespread closures, treacherous travel, scattered power outages, and downed branches," the weather service said.

Right now, we are still 48 hours away from the winter event, but as we get closer, it is likely to be upgraded to a Winter Weather Advisory or a Winter Storm Warning.
