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.

A Winter Storm Watch that was in effect for several counties has been canceled. Lake effect snow showers will continue across the primary snowbelt Thursday afternoon/evening. This is where another 1 to 2 inches of snow will be possible before the end of the day.
